I have only trued a couple of uppers and that was because the customers complained about grouping issues. Both rifles exhibited a visually skewed barrel/receiver relationship. When mounted between centers runout was apparent on the assembled uppers. Barrels showed no runout between centers. One...

If you are looking to pin it in place then it typically is beyond the scope of homebrew Smithing. The FSB must be held in precise alignment while the fsb is drilled/reamed. A jig or fixture is best. I do them all the time, PM if interested.

I use strips of copper sheet, you can cut through the leather pretty easily.

Be sure to use a non graphite antisieze or grease on final assembly. The 3 torque and loosen cycles should be with dry and clean threads, it burnishes the threads and allows for an accurate final torque reading.

Don't quite follow- did the screw head break off leaving exposed screw shank or is it flush with the receiver? Did it break when you were removing it or reinstalling it? If it broke and left a portion of the shank exposed I would try Kroil or similar, a bit of heat and either vise grips or...

Only bed the scope base if it needs it. Mount it using just the front screws and just snug them. If the rear of the base is not contacting the receiver then bed it. Seeing how the stock has the block, if you want to bed something then do just the recoil lug.

Bedding the Choate may prove difficult. If it is a typical plastic molded Choate getting the bedding compound to stick to the stock is the trick. Every plastic stock I have seen that was bedded eventually popped the bedding loose. Personally I won't bed a molded plastic stock.

That is nice PCR. What is this pipe tape?

Not sure what pipe tape is but if you are referring to duct tape or similar it's not enough clearance, especially on a wood stock. A wood stock will expand/contract due to environmental factors such as temperature and humidity. The humidity here in CO is not as bad of a factor as say, Missouri...

Don't bed the entire barrel. Just do the first 1 1/2" or so in front of the recoil lug. I like to really rough up the surface of the stock where ever Devcon will go. I usually undercut everything by at least an 1/8" with all kinds of nooks and crannys. This does a couple of things: by...

You can use red Loctite but it does not have the heat resistance the Rocksett does.

Sorry guys, I should have clarified that dimension. .620 is generally the length of the threaded shank. I would not be the least surprised if Rainier denies your claim due to the machinist tinkering with the threads. He destroyed the evidence of the faulty threads.

Don't worry, your not bashing them, your just being honest. IMHO Kimber is really over rated for what you get vs what you pay. I have worked on Kimbers out of the box that would not run, and for stupid stuff that should have never left the factory. 2 with barrels that overhung the ramp, one...

Spec for 1/2 x 28 is .620. I have found that some devices are short threaded so when I thread a barrel I typically go to .600. The brake is fine, the SureFire stainless is hard as hell and the only time I have seen one damaged is when the remnants of a hardened pin rolled the first 3 threads...
