A Neat Trick

I went to visit an elderly gunsmith friend today with a problem.  ??? I had a receiver shell that had been squeezed (probably in a vise while removing a barrel) and needed to spread it back out.  I was considering making a wedge, a tiny little jack, and several other methods, but he said to take a short (or shortened) fine thread bolt and matching nut, polish the ends and simply unscrew the nut inside the receiver opening until it was spread to the necessary width.  So simple, so cheap, and it worked in about 15 minutes including sawing off the bolt and polishing everything.  I hope somebody else can benefit from this tip sometime too!   Smiley

The shell was a little smooth side low-wall receiver and I believe it was a 5/16" machine screw and nut I used.  FWIW, fine thread is better than coarse, of course.  Smiley

You did notice that this thread is 15 years old didn't you?  I don't know the exact amount I had to "un-collapse" the receiver shell, but it was enough that a breech block wouldn't begin to enter it.  I would guess about ten to fifteen thou, at least if not more.  The point is (or should I say was) the overall effect was that the shell was pressed in enough to be unusable but was easily pushed back out with no heat and no special tooling... with very satisfactory results.  Yes, that low wall receiver subsequently got used.

Hey Frog that is exactly the way I fixed a Hi Wall action that I collapsed removing a Barrel. When I discovered what I had done I spoke a lot of those strange words regarding my heritage. Then thought about it for awhile. I came up with the same procedure. Took a little effort and patience but I got it
where a original Breech block would slide in and fit as though it had never been messed up. As a result of this experience I also made up a set of shims for both Hi Wall and Sharps Borchardt receivers. These are the two actions I do the most work on by choice. Have not yet needed to straighten a Borchardt or another Hi Wall. Got real careful after that. All it takes is a hard look at the design of Single Shot receivers and you can see that all the strength is in Recoil front to back. Almost any Clamping over the Flat side will collapse the action into a Trapezoid shape. And by the way folks, some have posted ("Just put the Breech block into the Receiver for support") That will not always work, first the bottom of the Block is not a tight fit and the Side walls of the Block are empty at the bottom and will  collapse, so now you have two pieces to fix. Solid shims are the best. I use mine in conjuction with Gage Blocks for a tight support fit from top to bottom. Also keep the Lower Tang in the receiver for just a little added support. Regards FITZ.

Hey Fitz,
For probably one of the only times in my life I can honestly say “it wasn’t my fault!”  Cheesy I bought that receiver shell stripped at one of the first OGCA shows I went too... it was cheap, and I guess the seller knew what he had, but fortunately for me it was an easy save. 

After 15 years I can’t remember whether it was Frank Miles or Charlie Dell who turned me on to that trick, but I recently stumbled on a pair of wedges that Charlie and I made for a similar task.  By comparison, the “screw jack” works a lot more easily.  Smiley

PS  Be sure and put the last Friday and Saturday of June on your calendar for a little Southern Schuetzen.  Didn’t DW move back up there?  If yes, bring him along!  Cool
