Convert radial or 3/8-10 drilled shaft to 5/16-14

[HawaiianEye]

How difficult would it be to convert a radial shaft or a 3/8-10 shaft to 5/16-14?

In my mind, it seems that it would be a lot easier than what some of the cue wizards on here do with a lot of their other repairs.

Is it as simple as plugging the hole, re-drilling it, and then putting in the insert?

Thanks for any information.

Hi Eye
Nope. It's even easier than that. You don't have to plug it. The deeper hole after the insert would be filled with epoxy.

Thanks, sir.

Is the inside diameter of the shaft the same as the outside diameter of the insert?

No Sir
Radial uses a 5/16" hole. 3/8x10 is usually smaller but some still use 5/16" also.
Brass and phenolic all threaded 7/16x14 o.d. inserts use a 3/8" hole. If you were to use one of those self aligning inserts that have a 7/16x20 short thread, then I would plug the hole with phenolic because it's my opinion that a thread length that fine and short, doesn't belong in wood. Constant tightening can suck it out.

What he said. ^^^^ Great answer to your question, especially the phenolic and 7/16x20.

Easiest conversion there is, IMO. Bore, thread, glue, done. I've installed hundreds of inserts like that into wood, and have never had one come loose that I know of.

Easy yes, Don't you think Predator had a good reason for using a non wood plug under all thier uni loc inserts besides spending more time and money on thier product?
