But the way it mounts at the bottom will be the same. My 66 bars threaded onto the studs, no tire clearance issues.

Well. Ya'll can call me a fool. I use panhead machine screws, lock washers and lock nuts instead of rivets. Never had a problem.

That is some beautiful work. Precisely why I love these machines--because they invite you to have a relationship with them, and then reward you for the effort.

I like the vise tool, by the way. More like what I'd have made instead of that expensive jig in the earlier post. Nothing wrong with, just more than is necessary IMHO.

I wouldn't think so. Especially with a little loctite on there, as the only force exerted on the screws is shear, and no way they're getting severed with so many of them around the circumference. Probably Harley riveted them on not just because it's secure but to save time in assembly--which means more profit margin per part.

In fact, it looks like one could bend some little flat washers in a vise with one whack a piece, and they'd take up the distance between the nut and drum, effectively acting as a locking tab. So, the nut would stay put and you'd just turn the screw with a wrench torquing a screwdriver that had a square-section shaft, or with an old-style manual impact driver. Bet they'd never budge...

This one probably won't work on big twins..

Actually, Max, I think you've located the right part, as the specs say it is intended for FLs and other big twins. That said, here is the same tool on eBay for $197 with free shipping... amazing how much some people (like W&W Cycles, evidently) try to gouge us Harley owners...

Anyhow, for $200 it's beginning to equal the time and materials to make a similarly beefy one, IMHO. The linked eBay listing says it fits 37-52 EL,41-72 FL.

Follow-up to the last post.

I just priced the steel stock and thought (very briefly) about how much beer it would cost me to use my neighbor's lathe and mill to make one up...

...just ordered one from the link in the above post.
