2000 to Present with progressively more difficult projects starting with the most recent.
The first Chariot stand-on riding floor scrubber . Responsible for internal design of sheet metal parts, welded assemblies and plastic surfaces, to achieve desired functionality.
Completed model. (Colors are for ease of visibility only) Created key external components from Industrial designers imported file (ICEM).
Views of rotational molded tank showing internal surface detail required for machine functions.
Additional view of tank details.
Chariot lower frame: Designed modular welded sheet-metal component & sub-assemblies. Weight is transferred from the center front drive unit, down the middle channel about mid-way, then spread laterally down the sides to the rear wheels
Upper frame: Sheet-metal sub-assemblies, also modular, support upper body of operator and controls.
Electrical housing (Rotational molded) & sheet metal control panel attached to upper frame section.
Vacuum formed bumper assembly provides flexible protection to customers facility.
Rear cover attaches over the rear axle & back of control panel. Tilts back or can be removed completely to access batteries.
Developed original layout for swinging squeegee: Linkage pivots around the center shaft of the front drive unit to allow nearly 100% pick-up of water on 90 degree turn.
Steering components for front drive unit. Designed brackets & shafts for maximum adjustability. Sourced chain & sprockets to achieve 3 to 1 steering ratio from lock to lock.
Tank with internal bag (bladder) system. Bag designed in sheet metal module to allow it to be cut from a single piece of material then seam welded together.
Vacuum installation & seals. Rear surface of rotational molded tank allows exhaust from vacuum motors to dissipate downward through the body of the machine.
Chariot Burnisher for which I did the original functional development work.
Compact 17 inch scrubber cost reduction & improved squeegee. Total cost was reduced by 50% . Squeegee performance improved by more than 50%.
Screenshot of completed model with squeegee.
Improved squeegee assembly (top view) showing transition (in blue) which allowed more freedom of movement without sacrificing any performance.
Bottom view showing stainless steel inserts (dark gray) on both sides of center opening providing additional weight to the otherwise lightweight aluminum assembly.
Cross section showing smooth transition from intake (gray portion above thin squeegee blades) to hose end of transition piece.

Cutter front & rear views.
Glide sit-down riding scrubber. I helped release most of the final drawings for production.
Compass multi surface machine, able to inject chemicals & recover them as well. I helped with releasing final drawings.
Required to improve function of this floating side squeegee for previous generation ride-on scrubber. Inset shows old design.
Redesigned fan housing with integral cord-wrap & wheeled handle.
Designed Engine Stands and Cradles for the Boeing 777 engines, as well as Tow bars, and some hydraulic tubing. 1992 to 2000 liaison between engineering & production personnel
