POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

lol, I said that, square headed thing as a joke mostly. I dunno of you guys have seen old shafts on any antique machinery, but they all had square headed pointed screws haning out of them everywhere, and the pulleys or sprockets still fell off of em..

I suppose its just cause that's what I worked on most of my life.

Take a set screw, or grub screw, lathe a point in it, or deepen the cup, anything you can think of to get that screw a deeper dig into the shaft. then blue loctite it in there as tight as the allen head will stand.

If you hadn't made such a pretty pulley, I would have suggested you go down to the motor store and pickup a taper wedge lock style, two piece pulley
like you'd find on an air compressor or other decently sized motor and get one of those installed. Those don't fall off.......ever

Yes, the belt will be running out at the pitch line, but there still wouldn't be room for a square headed pointed lock bolt in the bottom of the V.

I'm glad you know what you're doing, so are not becoming confused because, IMHO, too many contributors don't read all the replies and don't know what's going on. It's a chronic condition and probably has no cure.

or drill a dimple in the shaft so it holds and does not slip. It then allows you to get the pulley off if you ever need to without a problem. Because a good fit becomes an impossible pull when you raise that mark from the cup pointed set screw.

I read your previous suggestion regarding the square head set screw, but I didn't get the joke.
No problem. You're entitled to your opinion. It does make more sense to me as a joke.
However, please include "LOL" or :grin: or the like when it's not a serious suggestion. It's the internet.
