Looking for a gear, any gear with an 8mm shaft bore will work, with two screw locking mounts. This way I can lock one and drill a hole in the shaft for my gears which have a single lock. Willing to pay for it's cost and even return it after I am done if you like.
Anyone have a spare 8mm bore gear?

I have an aluminum 13t HTD5 pulley with an 8mm bore sitting in a box; 3 set screw holes.
Any reason you don't just file or dremel a flat on your shaft, though? Also unsure how you'll be able to drill without ruining the threads in the pulley.. or why you even need the pulley?
Motor shafts tend to be case-hardened steel, which really isn't something you want to be drilling into with an ordinary bit.

You could mark the spot, pull the gear, then drill it. I agree with brent though, drilling through the pulley will ruin the threads, and you dont need anything more than a flat spot and some loctite.

I have carbide drill tips, should drill thru it. It would not work unless I have the gear to hold onto while locked onto the shaft while drilling. Much cleaner that way. I guess it will just have to ruin the threads.
On my stock brushless motor it is a mess with just a flat spot. I remove the gear every month just to realign and tighten again, it is always turned to the side. This is a scooter with 10" wheels so there is more force on the gear then a skateboard would.

I'm still convinced there's a better way to do it, but you can PM me with an offer.
Are you using a drill press, or...?

If your dremel press is rigid and you're holding the shaft in a vise, I don't see how helpful a guide hole could be.
Also:
If your axes are parallel and you make a perfectly horizontal flat on your shaft, there shouldn't be any reason for your pulley to wander. Your system obviously won't be 100% perfect, but the set screw should do a pretty good job of stopping any sideways motion. In theory, anyways...
( I've never personally had any problems with my flat-on-the-shaft setup, but then again you might ride a lot more than me )
