Butch, As I stated, George is right. I was referring to the Rule 101 about checking something in the machine the work was done in. We do check chambers for final runout in the original set up.

George, To inspect a piece faced in a precision way, What you describe is certainly the best way. However, it is common to check a finished chamber for runout and that is usually done in the original setup which involves the original machine. I think there...

George,, I must certainly agree with your 101 inspection rule, However, I know of no way for starters other than to veryfy the machine your working with. Surface grinding a part simple duplicates the path of the machine for example, but top and bottom may not be parallel. Facing a...

Wilber, given a 700 action , add bases and check with a straight edge . You will find notoriously that the two bases are not in alignment. It is comon for the rear bridge to be tilted backwards and often neither one will be level because the rear bridge may be tilted to one side or...

AL, yes, you could face a large surface with the crossfeed locked , then retrace it with a good dial indicator. If you have access to a good surface plate, you could also check by laying it on its newly faced surface with a dial . You will be checking it for any rocking motion with the...

In the Houston warehouse story its somewhat ex[lained how the action and barrel threads were lapped together. When you consider that some lead screws may not be perfect or may be worn in some spots, Its hard to believe that all barrel tenon's have perfectly uniform threads. I might also add...

No doub't it has bben tried. Back quite a few years ago, I asked Ferris Pindell how best to fit a barrel to a mauser action. He replied that it would be near impossible to seat a barrel on both the internal and external shoulders. That he had tried. That came from a way more savy guy...

Just wondering if you do this with all your AR guns, and are your programs better for it

In any typical action, I cannot see were equal surface area could be found for an internal shoulder and receiver face. Since that is unlikely, compression would never be equal. The other side of this and as AL states in a different way, is you cannot both stretch and compress a barrel...

This post will be read by savage lovers as pure Blastphemy, But I have been playing with a savage for some time, making changes often. I did away with the floating bolt head, actually pressing it into the body, and found no difference in its performance.

It should be mentioned that on equiptment lists, often the sleeve is not mentioned, just the brand of action

This seems common with the jet lathes of that size. The seal at the chuck end runs on the spindle, but on the other end the seal runs on a sleeve wich is part of the bearing adjustment with the bearing lock rings. The problem is that that sleave is not alway concentric causing the seal to...

Yes, the Ruger ppc chambers are very generous. I have seen this in both a 22 and 6 PPC Ruger

Skeetlee, Take the time to become intimately familiar with your machine. Make small parts. Put numbers on paper and learn how to sneak up on them, like it is a $1000 dollar part that can't be tossed. Think forward about what is the best way to proceed, before you do anything. Keeping...

I think its fair to say that many of the sleeved remingtons seen today are not very new. Most were built 20 or more years ago. As such custom actions were not as common as today. Those sleeved remingtons, often lacked the refine methods that would be used today, like truing. It was...

Skeetlee, My lathe is a 12 x 36 belt drive. I did not buy the stand, as it was not very ridgid. I made one using 3'' angle steel all welded with a 1/2 plate on top. The base has adjustable feet which allows it to agree with the floor. Using a rubber spacer under each foot has made it...

Thanks AL, sounds good

Getting firing pins to function like they belong in a Benchrest rifle is really the frosting on the cake. Poor quality shrouds are common, but the culprit is actually the bolts. I really doub't that the threads are put in very many bolts with a piloted tap. Done in a machine or not, the...

I have one for right handed metal, with left handed thumbhole, yup its factory. Like you, I need a rt-rt

Al, did the increased capacity change the loading density, or is it still 101% fill.
