I use the Vise ProV2 Oval thumb inserts and the trouble happens when I am gluing the insert into the thumb hole after the bowler has aligned the insert. I place a mark on the ball and a mark on the insert to realign to the correct position. OK, the glue I use is the Krazy Glue Gel form. I glue the thumb hole, press the thumb insert into the hole then it always happens about 3/4 of the way into the thumb hole the insert starts to get really hard to push into the thumb hole the last 1/4. I usually have to hit the insert really hard with the palm of my hand or slam the insert on the floor for the insert to reach the bottom the thumb hole.

Does anyone have a better process of gluing the oval thumb insert and keeping the alignment?

I just hate to push the insert into the thumb hole to fast because it makes it difficult to keep the oval thumb insert alined. I could use round thumb inserts where it wouldn't matter but I and alot of people I drill for like these oval thumbs.

Thanks
Mike

Anyone else use 5 min epoxy? Does it work and where can I purchase some?

Turbo sells slow-zip glue for inserts and slugs that is gap filling, also there are other extended time super glues including Loctite 15 second, which is sold at Home Depot.
If you are looking for a specific type of glue, a good hobby shop is another place to find all types of glues and cure rates.

You can get any of the epoxies at Lowe's or Home Depot...

I had issues with my molds coming loose and sliding out w/ regular liquid and gel super glue, so switched to a 30min work life epoxy for my molded thumb slugs. It is a 2 part epoxy and usually about a nickle size amount is plenty for a slug. Hope this helps!
