Shaft collar

[OneIron]

I know this is probably a dumb question but here goes. Friend of mine wants me to replace the shaft collar. Nothing fancy, just black delrin. Is the collar conical or cylindrical? Just curious whether I will need to use my taper bar to size the collar or just cut it to size as a cylinder.

I know I could just measure another collar but It's going to be a while before I get back to my shop.

Thanks!

Best to practice on some scrap before doing customers work.
I have never seen a non conical shaft collar.
They are usually the taper of the handle.

If the collar on the cue now is conical then it needs to be conical.If not then you can cut it cylindrical.I wouldn't use delrin.You may have problems with it not glueing well.

Best Wishes,

I agree with the other replies, and that You definitely don't want to use delrin there, nothing but problems will follow. It is durable, so Maybe on a butt cap if machined and installed correctly, but personally I don't even use it for that.

Delrin is no good for collars. Use Juma, double black linen, or something else. Delrin (acetal) won't hold glue.

Not quite true, there are now special primers with some specific glues that allow the bonding of acetyl to alot of other materials . The down side, they are really toxic and very nasty to deal with.

Using alternative materials as been suggested is a better option.

Thanks. I didn't know about the primers, but that toxicity thing puts it off my menu.

Thanks, everyone. I've got some black linen I'll try. It's a customer's cue but a very inexpensive oriental model. Customer is insisting I do the repair and he'll take the risk.

I threaded a Delrin and used Gorilla glue as a test .
Two days later, I machined the delrin .
By the time I got down to the wood, delrin pieces were still inside the threads.

The Gorilla is a beast. A local Lowes store had a block of wood Gorilla'ed to a cinder block. You couldn't wack the block off with a hammer.:grin:

Hi,

If you check with Gorilla Glue they say don't use on phenolics. Try 2 part epoxy.

Rick I've used it multiple times in the past with phen & have never had a single issue. The quicker drying white works great as well.
