Anyone use LB phenolic to plug a 3/8-10 shaft hole, and then retap? My concern is once repaired, the tread will loosen on the pin while in use. I have seen a black plastic used, but not sure what they are using. thanks for any advise. Steve
 
Not sure I've seen LB, but have certainly seen some canvas based stuff used before for this.......
 
Hi,

We use garolite le for all our shaft inserts. 1/2" dia x 2" with a 1/8" hydraulic glue relief hole in the center. Glue with G5, face the drill and tap in 4 hours.

Not one failure on over 250 shafts made.

Omega DPK used black phenolic as a feature on all of their cues and we are omega groupies and followed their lead on this feature on our cues.

Good luck,

Rick G
 
Why did you choose garolite?

Canvas or Linen phenolic both work fine to plug and tap with. I make brown phenolic inserts with 1/2-20 OD threads and .290 ID hole ready to install, bore and tap.
 
I've had no issues at all using phenolic, Threaded or non threaded because It holds glue well.

I've seen some cues with delrin inserts/plugs though, and that's another story. It does not hold well, especially when not threaded into the shaft. I've fixed a few of them that pulled out just enough to cause a issue with the faces matching up.

good to hear

Thanks for all the replies, I have the canvas based brown as well. might try that for the second go around. thanks for the help

edit: Any changes to the minor dia for 3/8-30 i used .3120, and seemed a bit loose. Going to try .308 or so next time. Thoughts please

I'm going to suggest that changing your minor dia. via a smaller tap-drill
won't give you a tighter fit. You could use a .296" and it would still be loose.
Your minor is not the problem, it's the major.
Taps & pins can vary greatly in their major dia.
Put calipers to your tap then measure the pin and you'll see what I mean.
