2. This is what you will be marking out today. – Using your plan from 3D modelling to help you
3. These are the tools you are will be using: - Learn their names! Steel Rule Dividers Scribe Centre Punch Engineers Blue Engineers Square Hammer!
4. Start by cleaning your material to remove any dirt or grease – This helps the engineers blue go on.
5. Egineers Blue Apply the Engineer’s Blue to the metal, but only cover ¾ of the metal.... The rest is a waste!
6. Take the Engineers square and place it against the longest side of the metal, so that the thinner ‘blade’ of the tool is running just inside the edge of your piece of metal. – Take your scribe, and using it like a pencil, mark in the engineers blue a line from top to bottom We do this because the edge of the material is not 100% or at 90degrees to the other side, hence our hexagon would be wonky.
7. You should end up with something like this... Try and keep the gap between your line and the edge of the material as small as possible to minimise waste!
8. Now place your steel rule against the top edge exactly, and right against the line you just drew. - Now make a mark with the scribe at a measurement of 25mm. - This is the centre of the line you just drew as the width of the metal is 50mm. Make a mark at 25mm...
9. Slide your ruler along the top edge, still keep it inline with the top edge and make another mark at 25mm Keep Rule flat against top edge! Make another mark at 25mm but further along
10. Now draw a line ‘through’ both of the 2 marks you just made...
11. This gives you the exact CENTRE LINE of the piece of work
12. Measuring from the right hand end vertical line, make a mark along the line you just drew at 25mm (this will be the centre of the spinner)
13. And Again at 0mm (this will be the left side of the spinner)
14. You should now be left something like this.... 0mm 25mm 50mm
15. CAREFULLY Line up the point of your centre punch with the 25mm mark and sharply hit it with a hammer JUST ONCE!
16. Do the same at the 0mm mark and the 50 mm mark so you have 3 dents, each 25mm apart.
17. Take your dividers, and using the adjustment wheel, set the gap between the two points to exactly 25mm using a steel rule
18. Put one end of the divider in the dent you just made in the middle, and then draw a quarter of a circle in one of the corners as shown....
