Brass or copper inserts for a bbl spider

[Richard]

Sometime ago a saw a great idea for the inboard spider inserts. The issue I am having with the softer inserts is with a bbl that you have to come down on the tapered portion of the bbl shank. ( Rem Varmint Contour ) After you do several bbls the inserts start to mushroom. I saw a ball brg with an aluminum insert to match. Great idea!
I can figure one out but thought it would save time if you could point me to the thread.

Richard,
I first saw them when an Aussie friend showed me what he uses. I will PM an email address for another friend that does this also. He has photos and will be happy to exchange info.

Appreciate it

Thanks Butch

Dean will be mad at me for calling him an Aussie.

Richard,

This is what I think you're talking about.

Save McMaster Carr to your favorites. A first class website, and if they don't have it, it probably doesn't exist.

cooper or brass

Cooper won't scratch stainless, brass and aluminum will.

Thanks again!!

A lot of good links and I appreciate it very much.

BTW: Brass and Aluminum scratching bbls has never been an issue with me. I have Aluminum jaws in my new hermes and never had problems. Same way with brass inserts in the spider. I have used copper also.

Copper Inserts

Hello Copper is the way to go it will hold the barrel under the torx your talking about. I had made some from aluminum kept have the barrel move a little couple thou. during chambering. Went to copper I have not had that issue since.
