Good point @longhairedboy I used a set screw and I’m pretty sure I’ll never be able to remove my motor pulley without some serious Dremel Tool destruction of one or more components. Thread locker really works! and when the screws are small and fragile, the thread locker wins!
Although I’ve had some successes using a heat gun to gently persuade the thread locker to release its grip.
I just received my two Tacon Big Foot 160’s in the mail. Super excited to use these monsters. I want to make a keyway for both, but I’m scared I’m gonna screw it up. I don’t have the know how to replace the shaft if I do screw it up. Are there any tutorials with video or pictures. I do own a dremel. I’ve had it since Christmas, but have yet to use it.
replacing the shaft is real easy. just take off the circlips, undo the grub screw in the back of the can and tap it out with a drift or dowl.
you may need to heat it just a little with a torch if its tight.
I received a few keyways from @torqueboards. 12mm and 8 mm keyways if I remember correctly. Would making a 12mm keyway be fine or would combining the two to equate to 20mm which would cover the entire length of the pulley be necessary?
The tacon bearings and shaft are pressed in, which is nice. You don’t need to take out the bearings to get the shaft out of course but the shaft is pressed in tightly. If I were u I’d leave it in and keyway it connected. Putting it back together without a press could screw it up
@torqueboards I’m deciding if I should get the keyways done at a machine shop or do them myself with my dremel. Does the position of the keyway make a difference? Center of the shaft? Near the end? Near the beginning?
I’d estimate your paying at least… $30-40 bucks. I’d suggest buying a new motor with a keyway and just use that one as spare and run it with just 2 flat spots.
I recently had the same problem and I just drilled a small cone at the right place that fits the cone tip of a grub screw perfectly! pretty easy to do with any drill press and extremely solid connection between pulley and shaft!
