Hi, thanks for the idea.
The cog has a 10mm diameter bore in it. It was for the original motor shaft, and the cog was held on it only by a simple nut and the friction force what this tightened nut gave to it. So the actual face of the metal is not 4x18mm... It's smaller due to the hole in the middle of the cog. The shaft of the motor I use also has a hole in it with tiny grooves. I figure I could drill that up to 12mm or so, get a little shaft welded into the cog and drill and tap a few small screws into the motor shaft to hold the shaft of the cog...? Would that work? Would that be any stronger then the 4x 10-ish slot?
