Receiver Measurements

[Neil Young]

Maybe this would be a good project to request data from others who are proficient with micrometers, or at least have micrometers--it's not that hard to do. You could then build a data base and perhaps key the measurements to particular variations. We all don't have the drawings, so if you can, post a drawing showing exactly where to measure. Interested?

How 'bout a pic showing where I measured???

"A" is the measurements in post # 12 above...

"B" are these measurements, taken from the barrel hood to the bottom of the receiver lug...

comm, 86434: "A"--.872"; "B"--0.966"
1937, 3649: "A"--.885; "B"--.976" [S/42]
comm, 6782n: "A"--.878"; "B"--.972"
Finn?, 77z: "A"--.873"; "B"--.965"
1917, 8514: "A"--.874"; "B"--.970"

This is a better area of measurement; I believe the lug is held to higher tolerances than that area under the hood...

...And the "B" variance from least to most is only .011"...

I used a Starrett dial verniers for this little test...here's pic of my measuring...

I have several 1" micrometers (well, who doesn't? ) but I prefer the dial verniers...they're easier to use...

If anyone is going to make up a database for these measurements, I'll do a better job with my 5...Serial # link to measurements at least...and measure 5 times & take the average...

Now...Why would anyone grind anything off the chamber hood??? I thought the idea of faking was to *add* characters to the receiver...crossed rifle, skull & bones, any date to a commercial...

What would you grind off??? A year date??? Why???

I don't think whipping out a mic at a gun show and measuring a Luger is a good idea...It's sure to get ugly...and will draw a crowd like blood draws sharks...Even if the guy you're talking to is agreeable, the guy two tables over with a boosted Luger will complain about it...

Gentlemen:
My measurements are as follows:

"G" date, 7158a: "A"--0.875"; "B"--0.969".

BYF42, 3732f: "A"--0.871"; "B"--0.968".

OK: I went back and re-measured all five of mine...This time I made sure I was *not* measuring across a date, or a number on the lug, or across a dent or ding...and I got several different measurements...so the letters/numbers and any dings or dents will affect the accuracy of the measurements...

I also made sure I was as close as perpendicular to the horizontal plane as possible...I noticed that if I went just a bit off 90º that the measurement would change...

The receivers are "fatter" on the sides than on the top/bottom...So the least measurement will be 90º from horizontal...or straight up & down...That's the one we want...
