Re: [FTC]: Set Screws Suck!!!

Also, try to not use set screws whenever possible and keep axles themselves stationary, but the components (wheels and gears) free to rotate on the axle. So, whenever possible, remove axle hubs and add shaft collars.

Re: [FTC]: Set Screws Suck!!!

+1 on filing the set screws flat on the tips. Things were much more stable once we did this.

If you are filing manually, put a wrench into the setscrew and hold the two together then rub along a stationary file or flat sandpaper. It's easier to keep the file perpendicular to the set screw. I like using a bare grip as it is easy to judge if you are being too aggressive either with pressure or speed or both by the heat you are generating. It should never be uncomfortable to hold.
