What is the best way to attach to a motor shaft? I was given a motor that has an awesome metal plate that uses a set screw to tightly attach to the shaft, but the best part is the the metal plate is perpendicular, as shown in this picture:

It's the perfect mount to use for projects, but I've searched around and never seen anything like this for sale, which makes me wonder if it was custom-made for this motor.
For my flying crank ghost, I used a u-bolt tightly attached to the shaft, as shown in this picture:

It works okay, but it's never really that secure.
There must be some kind of plate like the one in the first picture, but I don't even know how to Google for it, or to describe it to someone at a shop--"it's this metal plate, with a welded-on hollow piece that fits around a motor shaft and has a set screw to hold it tight to the shaft."

Search for a shaft collar. That will give you the ring with the set screws that you can weld your drive arm directly too. Just measure the diameter of your motor shaft so you know what size collar to purchase.

That's why I'm so glad I stepped up and got that Harbor Freight welder. Now when I need something like this, I just make it.

I just welded up a longer drive arm for the wiper motor on my new FCG rig. Much better than trying to bolt things together.

Thanks for the info on that. I've never welded before, ugh! But maybe I can use JB Weld to glue the metal plate on there. Thanks a lot for the tip on the shaft collar. Now I know what term to Google for!

You're welcome. I am thinking that would best be welded. I am sure you could have it done locally for a few bucks. I wouldn't trust JB weld to that job. I don't like stuff coming apart again.
