The Dufferin Glider Joint is the 5/16x14 piloted pin that looks like a JP Speed joint, not threaded all the way down.

The pin is screwed into an aluminum insert in the butt as we have seen in these forums, I have pics saved from Mike Webb's posts and others.

I am unclear on something.

If I want to put a fully threaded 5/16x14 pin in it, can I just unscrew the Dufferin pin from the insert in the butt and replace it with a 14 pin?

Would it require heat?

I thought I found a post describing this but now I can't find it.

I have a two old Dufferin cues in nice shape with this joint. I would like to be able to use them with other shafts, for example Joss.

I found this picture in an eBay sale and wondered if some hack was trying to change the pin. I don't want to be some hack. I can have it done by a cue repair person if I need to, but thought I would look into doing it myself.

I would say that shaft split because they tried to twist the insert out. Those inserts just pushed in.

Thanks.

Is it reasonable to pull the pin from that insert and replace it with a more standard pin?

What does it take to get it out?

I assume if replaced I would use Loctite on the new pin. I guess I would have to measure it and cut it to bottom in the insert.

This was the original joint screw. 1 3/4" long. I heated it to remove it.

LOCTITE????
PLEASE, leave this section! 😃

I have seen pins are epoxied into wood. I figured a metal pin into a metal insert would call for Loctite.

So...should there be epoxy, adhesive, glue, or just bottom the pin tight?
