It seems the Q: "how to add levelers" to a table that was not originally equipped with them is not uncommon.
Suppose low friction inserts were available in 1/2-13 & 5/8 - 11 were available.
1.) would that be of any interest?
2.) would there be a preference for delrin, or for rolled LE/CE phenolic?
3.) if metal was preferred, plain old coupling nuts could be used. Perhaps slimmed down on the OD on a lathe in the larger sizes.
User would drill a hole & install with a liberal dose of JB weld, or similar.
All the loads are in compression, so the fact that the inserts would not be threaded on the OD (so "anyone" could install them without owning 1" or larger tap) is not a factor. Delrin does not actually bond to most glues/epoxy's. However, with 4 notches and a ring in the OD, it would never come out or turn. Phenolic bonds, but would have at least one notch for glue relief in a blind hole.
I've recently been making tiny leg levelers for furniture, so it got me thinking about the pool table items. The ones in the picture are for shop-made rubber-footed adjusters into stainless feet. (not shown, need to take camera back to shop) Only 1/4 -20. But same concept.
Inserts are capped, so the epoxy does not get inside and cause a problem. So long as installer does not get too much in the front.
