Bore the hole .002" undersized.
Live thread it in two passes.
That'll be tight. Wax the pin.
Shamfer the hole with a 60* center.
I make these inserts for myself.
It's chamfer. And I know this is dealing with 3/8x10, but what's the viable option of doing this in 5/16x14 with a pilot?

I have done quit a few 5/16 piloted joints using phenolic. The last few years I have used Juma. Haven't had and problems with either.

I'm sure that you gathered that these inserts are not finished out on the inside. Having said that, you could certainly machine, bore, and thread for the 5/16-14 threads. It would certainly work, but I think over time it might fail on you. The length of these are such that the top 3/8" or so, depending on how deep you put it, will be left proud of the joint face when you glue it in. There's a couple of reasons for this. One is to give the user some latitude on how deep he wants to install it. The other is so that you have enough of the material left to get a good grip on it with a pair of channel locks or vise grips. If everything fits right, it will get pretty snug as it gets to the final depth. Of course, for the typical installation you would just machine the extra away before you drill, bore and thread. For your piloted 5/16-14 setup you would need to leave the amount you want for the pilot, machine it to your pilot diameter, and then drill, bore, and thread for the 5/16-14.
If I'm not mistaken, Nova cues used phenolic inserts. I don't know if they had any longevity issues or not. I don't think they built that many cues though.
Shoot well!

What size pilot did Nova use? And I know what size pilot my Schon and It's George has, what are the sizes of other companies pilots? Larry what was the pilot size you used?
Ok guys, here's how this will work.
I just can't spend the time to get into the whole pm each and everyone kind of thing so here's what I will do.
Joey is sending me his design, and I'll make a few test pieces and send them back to him to test.
Once we are there, I'll put together pricing and make a pretty big run on them. I'll come back to this thread and post the pricing and quantity packages. I think the pricing will be very favorable, even in smaller quantities.
From there, anyone who wants one can call our office and place the order. We can take credit cards or paypal and ship within a day. If we are out, they will tell you at that time, and you can choose to keep the order in so you have a place holder in line, or you can hold off until later and reorder.
You should expect a couple of weeks for me to build the samples for Joey. After that I should be able to run a thousand pretty soon and I'll post it up here.
My plate is pretty full, but I've committed, so I'll make it happen.
