Rear lower frame angle SBH

[kywoodwrkr]

Does anyone have the accurate angle that the framerear lower corner of the SBH is supposed to be milled to?
I'm trying to make a fixture to hold the frame and desire this angle.
Our CMM machine was disaasembled last spring in anticipation of a new one and some dumder head clerk at the capitol "lost" our purchase papers. We have to regin them.
So, I am now in need of an accurate reading on this angle.
Thanks in advance.

In Dougan's recent book is shown Mr. Ruger's original 1952 Single-Six frame drawing. This shows an included angle of the lower rear corner at 82 degrees, 15 minutes . . . +/- 10 minutes.

There is also shown a sketch of the grip frame, with an included angle of 82 degrees, 30 minutes, but it's noted as "first layout".

Some included copy in the book states that the prototypes were set at 85 degrees to match a Colt grip frame, but the first production guns were run at 83 degrees.

Not sure if that helps, but it should be "in the ballpark" for consideration. Were it me, I'd get hold of a gun and do some measuring.

Thanks to Mr. Dougan for digging up this info and including it in his book.

Measured the frame using an SPI protractor and was trying to convince my self that the angle was 82 degrees and 20 minutes by eyeball.
I think that I will go with the published angle of 82 degrees and 15 minutes and dock my grade accordingly! :-)
Making a fixture to hold frame while doing various and assundry 'things' to it.
We actually refer to those projects as toaster projects.
Avoids a whole lot of concern on some folks parts.
Thanks again.
