Component Fabrication: Mesh motor guard and aluminium skidplate

Posted: March 7, 2015 in Component Fabrication
Tags: , , ,

This custom made mesh guard is designed for the Team Associated RC18T and is intended for the open recess where the motor sits. The process of construction can be applied to other projects requiring a similar component. I have tried various lexan guard mods but found that they were not to my liking for reasons of aesthetics and or function. This mesh guard shields the motor from rocks and allows airflow around the motor and allows for greater heat dissipation.

PART 1: ALUMINIUM MESH MOTOR GUARD

Whenever I make a custom part I always prototype the part by making a template out of cardboard/posterboard. By prototyping you can verify dimensions, test fitment and test the process of making the part in 3D. I match the material thickness of the prototype with the material I intend on using for the custom part. This is very important especially with complex forms as material thickness will have an effect on dimensions drawn in 2D.

Parts & Materials Used:

x1 Team Asscociated 18T Chassis – #ASC21001
1/16″ (1.58mm) pattern aluminium mesh
2mm high density foam
0.5mm posterboard
Painters masking tape
Selleys ‘Kwik Grip’ contact adhesive

PART 2: ALUMINIUM STONE DEFLECTOR/SKIDPLATE

This is the secondary underside component to the mesh motor guard (Part 1).

It is a custom alloy skid-plate designed to deflect larger debris and hard landings. It is made from 0.032″ thick 6061 aluminium sheet. Although this part appears simple creating this form is quite difficult due to offset bends on a small area. Not all steps are shown because there are quite a few.

Parts & Materials used:

0.032″ thick 6061 aluminium sheet
1.0mm posterboard
Painters masking tape
x2 3Racing titanium countersunk hex screws (M2 x 6mm)
x2 Annsmann anodised aluminium nylock nuts (M2)
Silicone Carbide abrasive paper (various grit)
Polishing compounds

      Hi Rooster,

      Thank you very much for your kind comments! 🙂

      I am happy to hear that you like my work Rooster and appreciate the small details. You must also be custom builder! RC building for me is a true labour of love.

      I am more than happy to share my obsession with people like yourself!

      Cheers.
