Oh man!? Too funny...? I read your reply too quickly, and I thought you signed your email "Love, Brent".? I'm flattered, but I don't think our friendship is quite there yet! :)? Had a good laugh about it when I realized my mistake.

I got both items at Aliexpress.?


I bought both M6x12x.3 and M5x10x.3.? Currently running the larger ones.? I'm considering stacking these with flat washers to get a little more "spring".


I purchased the 5x6.35 version to fit my 5mm shaft to the 1/4" worm.

The couplings are just slightly too long to fit without any modifications.? Firstly, I had to put a serious bevel on both sides of the coupling.? I did this with the drill press and a file.? This allows the coupling to just sneak into the recess of the worm block, as well as the slight recess where the bearing sits in the motor bracket.? The coupling still won't quite fit, so I also had to shim the motor bracket out slightly.?? You can see the bracket is not quite fully seated against the worm mounting plate.?? I just put a piece of wire in there to tighten up against, but you can really use anything you want.???

In the future, I will probably just drill through the 5/8" pocket where the bearing sits so it can be pushed inward towards the pulley, overhanging just a couple of mm.? This will allow? a larger recess for the coupling to fit in, and I should be able to tighten the bracket properly.? The bearing can be "floating" since it will effectively be kept in place sandwiched between the coupling and the pulley.? I'll put a couple of 1/4" washers on the shaft to keep the pulley from rubbing the outer race of the bearing.

Or maybe this will finally be the push I need to design my own brackets.
