Bolt sleeving

[Rflshootr]

What size is the bolt body turned to before installation of the sleeves?
What does everyone use to bond the sleeves to the bolt body?

Of the ones I've done, I reduced the diameter to around .650" and used JB Weld as bond. Before, I tried with Marinetex, and the result was bad.

I was advised to use JB Weld by experienced gunsmiths and it really worked.
