DECORATIVEMOULDINGS1INTRODUCTIONtrend routing technologyINTRODUCTIONKITCHEN &BATHROOMJOINERYWINDOWSAND DOORSThe use of the router for jobs on-siteand around the home is certainlyunder estimated. In this booklet wewill be illustrating thirty simpleexamples of its application.The router is the most suitable toolto use for many applications simplybecause it will get the job donequicker and will give a far superiorfinish than when using other powertools. Sometimes, applications justsimply cannot be done any otherway.We have divided this booklet intofive sections. Section 1 gives anintroduction into safety, holding thework and use of templates. Theother four sections are grouped intoWindows and Doors, Kitchen andBathroom, Joinery, and DecorativeMouldings.
2INTRODUCTIONtrend routing technologyv Always switch off the router and isolate from themains supply when changing cutters or makingadjustments to the router.v Before re-connecting to the mains supply, makesure the power switch is in the ‘off’ position.v Ensure that the power cable is kept well away fromthe cutter and cannot tangle or catch on the workpiece,jig or fittings.v Check before starting to cut that clamps will notobstruct the path of the router. When cutting through thefull thickness of the material, ensure that the cuttercannot foul the vice, bench edge or other obstaclesbeneath the workpiece.v Most construction sites only allow the use of 115vpower tools and this may be a deciding factor whenpurchasing power tools.v When routing, a flat and stable work table isessential.SAFETY FIRST
3INTRODUCTIONtrend routing technologyv Always wear eye protection such as goggles, andwear ear defenders if routing for a lengthy period.v Do not allow loose clothing to dangle over the workarea. Roll sleeves up and ensure long hair is tied back.v Keep fingers clear of the cutter and never touch anypart to try to slow or stop the cutter.v Practice the procedure first before switching on andconcentrate carefully on what you are doing.v Use dust extraction wherever possible. Manyrouters have dust guards as standard or as anaccessory.v Take care when handling cutters as they are sharp.Store them carefully.v Always feed the cutter into the material against therotation of the cutter.v Do not switch on the router with the cutter incontact with the workpiece.v Make sure the router has come to a complete stopand isolate the power before making adjustments.v Where possible release the plunge lock and retractthe cutter.
4INTRODUCTIONtrend routing technology1. Quick-action clamps are effective forholding the workpiece or jig to the bench and canbe positioned in seconds. Sash cramps or TrendClamp Guides are ideal for holding larger sectionsfor preparation and assembly.HOLDING THE WORK2. Toggle clamps are useful where repeatedclamping is required such as on work-holdersand support jigs. Alternatively if an obstructionfree surface is required, end socket clamps canbe used and require a 9mm hole in the materialor waste-piece.
5INTRODUCTIONtrend routing technology4. Cams, blocks and wedges used with asacrificial top may be more practical, where theworkpiece may be large and its surface irregular.They combine a quick-release facility togetherwith an obstruction-free surface for the path ofthe router.3. In situations where clamps or othermechanical devices are impractical, pins may beused. Where these may spoil the workpiece,double-sided tape or hot-melt glue can be used.This will only work if the material is flat, clean anddust-free.
6INTRODUCTIONtrend routing technologyA template is often used to simplify demanding copyrouting operations or as an accurate method ofspeeding up repetitive work. It also reduces the risk ofspoiling expensive materials. The use of a template willtherefore provide a solution for a whole range ofpossibly otherwise difficult operations.A guide bush is used for guiding the router around thetemplate. The guide bush itself, with its base fitted flushinto the base of the router, has a bush flange concentricto the cutter. This runs against the edge of the template.Templates can be cut from any piece of smooth sheetmaterial that is easy to work with and finish. Thematerial depth must be greater than the flange depth ofthe guide bush.TEMPLATES & GUIDE BUSHES
7INTRODUCTIONtrend routing technologyWhen designing the template shape remember that thedifference between the cutter and the outside guide bushdiameter needs to be allowed for. This offset iscalculated by deducting cutter diameter (d), from theouter guide bush diameter (D) and dividing theremainder by two. For external templates deduct thisamount from each edge of the template. For internaltemplates add this amount to each edge of the template.The offset for specific guide bush sizes and cutterdiameters is shown in the chart above. Choose a guidebush that allows at least 2 to 3mm clearance around thecutter allowing the waste to clear.inches mm10 11 12 14 16 17 18 20 22 24 26 27 28 30 32 40mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm- - - - - - - - - - 3.5 4 4.5 5.5 6.5 10.5- - - - - - - - - - - 3.5 4 5 6 10- - - - - - - - - - - - - 3.9 4.9 8.9- - - - - - - - - - - - - - - 7.3- - - - - - - - - - - - - - - 5.7- - - - - - - - - - - - - - - 4.1- - - - - - - 3.5 4.5 5.5 6.5 7 7.5 8.5 9.5 13.5- - - - - - - - 3.5 4.5 5.5 6 6.5 7.5 8.5 12.5- - - - - - - - - 4 5 5.5 6 7 8 12- - - - - - - - - - 4 4.5 5 6 7 11- - - - - - - - - - 3.9 4.4 4.9 5.9 6.9 10.9- - - - - 3.7 4.2 5.2 6.2 7.2 8.2 8.7 9.2 10.2 11.2 15.2- - - - - 3.5 4 5 6 7 8 8.5 9 10 11 15- - - - - - 3.5 4.5 5.5 6.5 7.5 8 8.5 9.5 10.5 14.5- - - - - - - 4 5 6 7 7.5 8 9 10 14- - - - - - - 3.6 4.6 5.6 6.6 7.1 7.6 8.6 9.6 13.6- - - 4.2 5.2 5.7 6.2 7.2 8.2 9.2 10.2 10.7 11.2 12.2 13.2 17.2- - - 4 5 5.5 6 7 8 9 10 10.5 11 12 13 17- - - 3.8 4.8 5.3 5.8 6.8 7.8 8.8 9.8 10.3 10.8 11.8 12.8 16.8- - - 4 4.5 5 6 7 8 9 9.5 10 11 12 16- - - - 3.5 4 4.5 5.5 6.5 7.5 8.5 9 9.5 10.5 11.5 15.535 4 4.5 5.5 6.5 7 7.5 8.5 9.5 10.5 11.5 12 12.5 13.5 14.5 18.5- 3.9 4.4 5.4 6.4 6.9 7.4 8.4 9.4 10.4 11.4 11.9 12.4 13.4 14.4 18.4- 3.5 4 5 6 6.5 7 8 9 10 11 11.5 12 13 14 18- - 3.6 4.6 5.6 6.1 6.6 7.6 8.6 9.6 10.6 11.1 11.6 12.6 13.6 17.6- - 3.5 4.5 5.5 6 6.5 7.5 8.5 9.5 10.5 11 11.5 12.5 13.5 17.57/641/85/323/1613/6433.244.855.566.3899.510111212.71315161818.2192022.225.428.57/3215/641/45/1623/643.825/647/1615/321/2--5/8-23/323/4-7/811 1/81 1/4OFFSET =D-d2GUIDE BUSH DIAMETERCUTTERDIAMETER= offset
8INTRODUCTIONtrend routing technologyTEMPLATES & GUIDE BUSHESGuide bushes are available in different diameters toallow various diameter cutters to be accommodated.Many makes of router do not offer a range of guide bushsizes. Therefore a sub-base should be fitted to the baseinto which the full range of guide bushes can be fitted.These are available in diameters of 10mm to 32 in 2mmincrements, and also in a 40mm size.Templates for use with guide bushes should not bemade from too thick a material otherwise it will restrictthe depth of cut. MDF, hard plastics and Tufnol are idealmaterials to use as they are flat and stable.TEMPLATE CONSTRUCTIONTo construct a template, often jigsaws or other powertools can be used to remove the bulk of the waste. Buttake time to make sure that the template edges are freefrom irregularities, as they will be reproduced in thefinished workpiece. Often the router itself can be usedto shape or produce the required slots and apertures inthe template.FEED DIRECTIONWhen routing, follow the correct feed direction,depending on whether it is an internal or externaltemplate.Keep the bush flange tight against the template andupon completion of the cut, release the plunge towithdraw the cutter rather than lifting the router away.Sub-base
9INTRODUCTIONtrend routing technologyTemplates are also ideal for use with cuttershaving shank mounted bearings. Theadvantage over guide bushes is that the finalshape will exactly match the template, makingthe template construction easier.Shank mounted bearings faciliate deep cuttingand profiling. In operation, the first cut ismade with the bearing engaging the template,and thereafter deeper cuts are made with thebearing following the board edge (see pages30/31).For external templates the router’s feed direction shouldbe anticlockwise. The cutter will also tend topull the router towards the template.For internal templates the router’s feeddirection should be clockwise.Cutter ref. 11/40Cutter ref. 18/55Cutter ref. 13/40
101WINDOWS&DOORStrend routing technologyAfter installing a new window or replacing a tiledwindow-ledge, timber window boards can be purposemade.1. Allow for the overhang at either end whencalculating the length of timber required. Choose thesize of overhang to match those in other rooms.2. A bull-nose moulding will be required on three ofthe edges. For 1” thick board, use a 1/2” radiusrounding-over cutter, Trend ref. 46/150X1/4TC orsimilar. Adjust the height of the cutter so that the topquirk is just clear of the top surface. The roller bearingfitted to the end of the cutter acts as the guide and runsalong the centre of the board edge.FITTING WINDOW BOARDSCutter ref.46/150X1/4TC1st pass 2nd pass
11WINDOWS&DOORStrend routing technology13. Make sure the board is wellclamped, and rout across the end-grain first. Then repeat thisprocedure for the other end andfinally rout with the grain. Invert theboard and then repeat thisprocedure to complete the bull-nosemoulding. Always rout in the correctdirection as shown.4. Notch each end with a jigsawand place in position. For fixing theboard in place, countersink andcounterbore holes for the screws.To conceal the holes, use amatching plug-maker, cutting plugsfrom a section of waste board. Thiscan be carried out by fitting therouter with a one-piecedrill/countersink cutter and a plug-maker.1.Make sure there are noimperfections in the edgebefore routing to preventreplication in the mould.2.Always make a trial cut on ascrap piece of material toensure the correct settingshave been made.3.Rout the end-grain firstbefore routing with the grain,to prevent ‘breakout’.4.Use the depth-stop, so thatthe cutter can be retractedsafely after each operation,without losing the depthsetting.ROUTING TIPS
122WINDOWS&DOORStrend routing technologyHinges can be recessed quickly and accuratelywith a light duty portable router fitted with a 1/2’diameter two flute cutter.1. First construct a jig from MDF or plywood. Markout the aperture according to the size of the hinge leaf.Allowance must be made for the offset between theoutside of the guide bush and the cutter diameter.Providing the template material is square, use the routerfitted with a sidefence to cut the aperture.2. Mark accurately the required positions of thehinges on the door and the frame.3. Clamp or pin the jig in turn for each recess androut in a clockwise direction.4. Remove the small radius in the corners with achisel.HINGE RECESSINGKeep the surface area ofthe jig to a maximum tosupport the base of therouter.Cutter ref.4/2X1/4TCKeep the support piece deep,for securing the clamps sothat they will not interfere withthe path of the router.
13WINDOWS&DOORStrend routing technology25. When setting the router to cut the correct depth, thedepth of cut can be pre-set using the hinge leaf itself.A. Place the router on the edge of the door and plunge thecutter until it touches the surface.B. Activate the plunge lock and release the depth stop.C. Place the leaf betweenthe turret stop and thedepth stop and tighten thedepth stop.D. Withdraw the hingeleaf. The depth is nowaccurately set to recess thehinge leaf.Hinge placed between depth stop andturret stopThis is a portable template jig designed forrecessing hinges in wooden doors and frames.The apertures and edge stops are initially setand the template is then ready for accuraterecessing of the frame and the door withoutadjusting the jig.The TREND HINGE JIGSwivel end plateTo locate on end ofdoor to give 2mmclearanceApertureGuide bushfollows thisEdge stopFor adjustment to suitwidth of hingeAperture blockFor adjustment to sethinge length
143WINDOWS&DOORStrend routing technology1. Mark the centre line on the door edge at theheight required for the lock. Mark the length of themortise and position of the spindle. Fit a long reach twoflute cutter, ref. 3/83D and adjust the sidefence to suitthe width of lock. Remove the waste in several passesand repeat the operation on the other face to achieve thewidth of the mortise.2. To rout the faceplate, first insert the lock andscore around the face plate with a sharp knife to preventfeathering on the door edge. An adjustable template canbe constructed for repetitive operations from thin MDFor plastic material. Rebate slots for adjustment screwswill ensure the jig is central to the centre line of the door.MORTISING DOOR LOCKSCutter ref.3/83DX1/2TCRebated slots
15WINDOWS&DOORStrend routing technology33. Clamp the jig to the door and adjust the depth ofcut to suit the thickness of the faceplate. Rout in aclockwise direction around the aperture. Remove therounded corners of the recess of the face plate with achisel. Increase the depth of the mortise with a chisel or3D-Bit if the lock body is over 75mm in length.4. Before fitting the lock, the spindles and key holeapertures on either face must be cut. To allow easyremoval of the lock when fitting it, leave it in the lockedposition i.e. with the bolt protruding.
164WINDOWS&DOORStrend routing technologyThe router is ideal for producing letterboxopenings, as the cut will be square, straight andclean.1. Mark the position of the aperture on both sides.Score the position on the opposing face to preventsplintering when the cutter breaks through.2. Make a template from either plywood or MDF,allowing for the offset between the cutter and the guidebush.3. Place the jig on to the door and secure withclamps or double sided tape. Fit a 30mm guide bush anda two flute cutter ref. 3/83DX1/2TC into the router.CUTTING APERTURES FOR LETTERBOXESCutter ref.3/83DX1/2TC
17WINDOWS&DOORStrend routing technology4The Trend Letterbox Jig is an ideal adjustabletemplate system for routing recesses in doorsquickly and accurately. The jig has a size-adjustingdevice which ensures the template aperture isalways square. Produced from aluminium, it willcater for apertures from 210 to 310mm long andfrom 46 to 82mm wide.4. Rout in a clockwise direction around theaperture, taking several passes to complete theoperation.If the letterbox has a sprung flap, rebate the aperture tocater for this.The LETTERBOX JIG
185WINDOWS&DOORStrend routing technologyTRIMMING A DOOR TO LENGTHWhen trimming doors to length, the cuttermust have enough length to cut thethickness of the door. This will in mostcases necessitate the use of a long reachcutter with 1/2” shank cutter and a heavyduty router.The trimming operation could be carriedout using a clamped batten with the sideof the router acting as the guide fence.Alternatively it could be done using aguide bush and a template.1. Remove the door and mark the required length.Score it on both sides with a marking knife to preventany feathering.2. Measure the distance from the outside edge ofthe cutter to the straight edge of the base.3. Clamp a batten guide this distance away fromthe marked line.4. Cut in several passes at increased depths untilthe full width is reached.

They can be used formarking and setting out, and for guiding portablesaws, jigsaws or routers.The CLAMP GUIDEWhen trimming internal doorsmany passes are taken toprevent overloading the cutterand the router.The same procedure is usedfor external doors when arebate is required.Cutter ref.3/83DX1/2TCCutter ref.4/2X1/2TC
206WINDOWS&DOORStrend routing technologyDecorative edgings for archways or arch formersfor brickwork can all be made using a simple beamtrammel attached to the router.1. Construct the beam trammel from 1/4” plywoodand 4” in width. The length will depend on the diameterof the arch.2. To fix the router securely, a 30mm guide bushfitted to the base of the router locates in a pre-drilledhole in the end, allowing for adequate support for therouter. Alternatively, the wood trammel can be screwedonto the base of the router using two of the threadedholes in it’s base.ARCHED MOULDINGS

This can eitherbe a screw or nail, or a bolt which is drilled through theplywood allowing the trammel to rotate.4. A decorative mould can be built up, using avariety of panelling cutters. Flute spacing and depth ofcut can be adapted to suit.5. The next operation is to cut the arch with astraight cutter and remove the waste. Reposition therouter and repeat for the inner radius. The moulding ofthe inner and outer edges can be carried out either byusing an ovolo cutter before cutting the arch free, orafterwards using a bearing guided ovolo.
227WINDOWS&DOORStrend routing technologyVISION PANELS IN DOORSWith the enforcement of fire regulations, visionpanels often need to be cut into existing doors.When a number of doors require this, then therouter and a template become invaluable.1. Remove door from frame and lay door flat on twotrestles and mark the size of vision panel required.2. Score with a knife on both sides, especiallyacross the grain to avoid any feathering.3. Drill holes inside the four corners of the requiredaperture and cut with a jigsaw from corner to cornerleaving 3mm of waste on the inside all the way round.
23WINDOWS&DOORStrend routing technology74. Construct a template from 12.7mm MDF. It’saperture should be the same size as for the vision panel.Allow enough material in the template to support therouter and to prevent clamps interfering with the path ofthe router.5. Clamp the template into position.6. Fit a heavy duty router with a template profilercutter ref. 46/09X1/2TC and trim the aperture in aclockwise direction.7. Square the radiused corners with a jigsaw. Withhollow doors timber strips should be inserted and gluedfor mounting the glass. Finally fit glazing bead and glassin position.BearingCutter ref.46/09X1/2TC
248WINDOWS&DOORStrend routing technologyROUTING MORTISE AND TENONSBoth the mortise and the tenon can be producedquickly and accurately with the router and asidefence.1. First mark the position of the mortise. This isusually equal to a third of the material width. Mark theunderside if you require a through tenon.2. Whenever possible choose a router cutter equalto the width of the mortise. Clamp support pieces eitherside to provide extra stability for the router base.3. Plunge down at either end of the mortise,remove the middle section in a number of passes.Cutter ref.3/20LX1/4TC
25WINDOWS&DOORStrend routing technology84. When routing a through mortise, leave the samesettings of the sidefence and repeat on the underside ofthe timber.5. Square both ends of the mortise with a chisel.6. Use the pre-cut mortise to determine the widthand length of the tenon.7. Clamp the timber sections with the tenons sideby side and cut the shoulders simultaneously. Using abatten to guide the router.8. Remove the rest of the waste by working therouter freehand. Work towards the shoulder line, thusleaving a good support for the router.
269WINDOWS&DOORStrend routing technologyFITTING INTUMESCENT STRIPOften doors and frames in domestic and industrialapplications are subject to fire regulations and aregraded according to their construction with a firerating. Safety regulations specify the fitting ofintumescent strips and smoke-seals. These haveto be recessed in order not to interfere with theoperation of the door.A 10mm diameter straight cutterTrend ref. 3/6 X 1/4 TC can be used to create thegroove for intumescent strip. It is used inconjunction with a light duty router fitted with it’sside-fence.1. Holding the door vertically, firstly remove thedoor furniture and mark the position of the strip on thedoor edge.
27WINDOWS&DOORStrend routing technology92. Adjust the side-fence and the depth of cut to suitthe strip. Rout along the length of the door in the correctdirection.3. For one hour ratings or wide strips a secondpass will be necessary after adjusting the sidefence.Repeat procedure for remaining edges.4. Alternatively, use the Trend Intumescent stripcutter set ref. 346. This purpose-made tool consists ofa 10mm wide slotter and bearing mounted on an arbor.It works on the face of the door or alternatively on theface of the frame allowing the strip to be inserted intothe rebate. Being bearing guided it reduces setting uptime and the slotter will also give a better finish than aconventional two flute cutter.Half hour rating One hour ratingDoor applicationsHalf hour rating One hour ratingFrame applicationsFrameDoorPlease refer to the local authority fire officer for the preciserequirements for your area.

2810WINDOWS&DOORStrend routing technologyTENON SHOULDER SCRIBINGThe shoulder scribe joint between mortise andtenon of a profiled frame requires special tooling.Matching cutters are available to machine theprofile on rails and stiles, and scribe the shoulderof tenons in 35mm and 44mm doors andframework.1. First prepare the timber sections to the correctdimensions. Mark the position of mortise, tenons andthe shoulder detail on the rails.2. Cut material to length, allowing for a smallamount of waste at both ends of the stiles. Cut themortise into each stile, see page 24 for details.3. The tenon is then routed to suit the mortise. Theshoulder scriber should be mounted in a table toprovide greater accuracy with the backfence modifiedso as not to obstruct the tenon.PushstickBackfenceCutter ref.SSP/1B
29WINDOWS&DOORStrend routing technology104. Use a piece of waste material behind the rail toprevent splintering. This is known as a ‘spelch piece’.With the shoulders of the tenons complete, cut theprofile on the stiles and rails. Once again, mount theprofiler in the table with the bearing on the cutterslightly proud of the backfence to govern the depth.5. Before applying any glue, test the joint by dryfitting and assembling the workpiece. When you aresatisfied apply the glue and cramp-up while the gluesets.Backfence Cutter ref.SSP/1A
30WINDOWS&DOORStrend routing technologyREBATING WINDOWS TO ACCEPT DOUBLE GLAZED UNITSSingle glazed windows can be upgraded withsealed double glazed units without having toreplace the frame or the sash.1. First remove the putty and any brads or pinswhich hold the glass in position.2. Remove the glass carefully then clean the rebateof debris. The depth of the rebate will require deepeningwith a router. This can be achieved in two ways:3. Fit a straight fluted cutter such as a 3/6X1/4TC.Using a batten as a guide for the router, place the cutteredge against the rebate and fix the batten against theside of the router. Repeat for all sides.11Batten
31WINDOWS&DOORStrend routing technology4. Alternatively, the rebate can be cut with a bearingguided profiler ref. 46/92X1/4TC which will initiallyfollow a straight edge clamped to the sash and thenfollow the edge of the rebate as it cuts deeper.5. Square the corners of the sash to remove theradius left by the cutter. Apply a bead of silicone or puttyto the rebate before inserting the new double glazedunits.6. Finally secure the glazing beads with pins,additional silicone on the back edge will keep moistureout.11TemplateTemplateBearing
32WINDOWS&DOORStrend routing technologyREPAIRS TO ROTTEN EXTERNAL JOINERY121. Timber windows can often be affected by theweather. Often wet rot will be confined to only onecertain area. It is therefore more economical to simplyreplace the rotten section with new timber and therebyadd ten more years to an otherwise sound window.This can effectively be done with a hand router.2. First remove loose rotten timber from affectedarea. Open the sash and make sure it is wellsupported. Make a template from a piece of 12.7mmMDF, leaving it wide enough to clamp and support therouter. Mark out the correct size of aperture and cut itout either with a jigsaw or router and a sidefence.
33WINDOWS&DOORStrend routing technology121. When making the template allow not onlyfor the removal of the rotten timber but asignificant proportion of the surroundingarea.2. Where possible avoid routing too close tothe joint between rail and stile which wouldweaken the window.3. Choose a cutter and guide bush thatallows good clearance for the swarf.4. Choose a cutter that has a sufficientlength of cut to obtain the depth required.ROUTING TIPS3. Fit the router with a 30mm diameter guide bushand 16mm cutter (Trend ref. 4/26). Secure thetemplate to the window with clamps rather thanscrews to avoid marking the surface. Machine therotted area, taking a number of passes with the routerin a clockwise direction.4. Remove radiused corners with a chisel and cuta timber insert to suit the recess, leaving the thicknessslightly larger to allow for finishing to obtain a good fit.Treat all exposed timber surfaces with a preservativebefore gluing. When the glue has cured, use a handplane to blend timber insert flush with the sash.Cuter ref4/26X1/4TC
34WINDOWS&DOORStrend routing technologyINSTALLING ROUTERSEALTrend Routerseal incorporates a dovetail barb whichprovides a simple self-fixing system, without requiring agluing operation.The seal can be used on the frame or the sash, by firstusing a matching dovetail cutter ref. 31/10L to form achannel into which the seal is tucked.Remove the sash from the frame and use the sidefenceon the router to act a guide.The seal is inserted in the face of the closing side of thesash, and will compress when in contact with therebate.13Dovetail Cutterref. 31/10L
35WINDOWS&DOORStrend routing technologyThe seal is very versatile and can be routed into the apexof the rebate in the frame.When routing in situ, the base is guided along the frameedges. As the corners of the frame will cause anobstruction, a chisel will be required to complete thejob.For insertion, the seal is easily slid in from one end ofthe rail or stile, or tucked into the apex or closing faceof the frame. The corners should be mitred and siliconecan be applied where the seal meets to prevent moistureentering the hollow section.13
36KITCHEN&BATHROOMtrend routing technologyJOINING KITCHEN WORKTOPThe joint between worktops that meet has often beenmade by fitting a surface mounted joining strip. Theseare both unhygenic and unsightly.Postform jigs can be hired or purchased to produce anear invisible joint within 15 minutes.The main use of the jig is to produce the mason’s mitrewhich consists of a male and female routed edge whichwill perfectly match.The underside is recessed to accept panel buttconnectors which will hold the joint together tightly.Biscuit jointing is recommended for greater strengthand alignment of the joint.14
37KITCHEN&BATHROOMtrend routing technologyThe jig consists of precisionmachined slots which guide therouter. Bushes are positioned invarious combinations of holes toalign the jig on the worktop.

The jig is held in placeby either quick action clamps oroptional clamping brackets.14The Trend COMBI 1001cutting the female sideof the jointThere are several applications for postformjigs, from cutting 90° joints, mitre cornerjoints for hobs, peninsular joints and cornerfinishes, either straight or rounded.221/2°HOB CORNERLEFT & RIGHTHAND JOINTPENINSULAR
38KITCHEN&BATHROOMtrend routing technologyCONCEALED HINGES FOR KITCHEN DOORSThe use of concealed hinges are the most popular wayof securing unit doors. It is important that the hinge islocated correctly into a pre cut hole.A drill stand and machine bit are the tools usuallyrequired. However, the router is also an ideal tool forproducing neat accurate holes, using a machine bitdesigned for use with a router and a simple template toobtain accurate holes. Machine bits are available to suitpopular diameters of concealed hinges.The template is constructed from MDF with battens toposition it on the door edge. The router is held in placeby the guide bush located in the aperture on the jig.15Router Hinge Bitref. 105/35X1/2TC

Cut new panels to size, allowing for anypipework and fixing locations.2. Mark the new bath panel with location for thedecorative work on the panel.3. Design a template to the shape of the panellingyou require from MDF or plywood. To make thetemplate use the router with a beam trammel to producethe arcs and batten guides for the straight edges.Ensure that the template is accurate and free fromblemishes as these will be replicated in the finalworkpiece.16
41KITCHEN&BATHROOMtrend routing technology4.

Trimming CuttersBearing guided trimmers can be used for trimminglaminate or hardwood lippings flush with the workpiece.To achieve best results and to prolong the life of thecutter, no more than 3mm of overhang should be left totrim. They can also be used for shaping material to atemplate.2. Profiling CuttersProfiling cutters have bearings mounted on the shankand are used for trimming the workpiece from atemplate. This type of cutter is advantageous whenfollowing templates as the ratio is 1:1, eliminatingcalculations for the offset or margin when cutting asquare edge.20Cutter ref.T46/0X1/4TCCutter ref.46/09X1/2TCCutter ref.46/91X1/4TC
