I agree - a PDF drawing with dimensions and notes is a cheap insurance policy.

Something else I like to do is show imperial measurements in red. With a page full of metric measurements its easy to forget that 1 or 2 might be in inches (IE for 1/2" shafts on gearboxes). That isn' ...

Really clear drawings definitely help. Apart from a 2D dimensioned drawing, a small 3D render of the part is customary. Add short call-out notes for more complicated features and never assume the mach ...

LOL, just for once I know something you don't Laughing Pinion wire is a length of rod (maybe 150 to 300mm) with spur teeth cut all the way along it. You just cut off the length you need for one pinion ...

My favourite solution for this sort of problem: buy some pinion wire and make your own pinion. Make it as long as possible and ream the bore under size. Also leave the teeth on the back of the pinion ...

Wow, that's painful to look at! They must have profile milled all the aluminium parts and then not bothered to do a secondary operation to square up the inside corners - very slack. It looks to me tha ...
