Troubleshoot This-2

[Kaylee]

Sorry sm.. I came late to the party.

Reading the Mr. Tuner's post, I was thinking it had something to do with the MSH, but only because he mentioned it as a modification from stock, and well.. that seemed the logical first place to look.

That said, I hadntt a clue how it would possibly be affecting things... gads! The things you see... color me impressed you guys!

When you can snatch this 45ACP case from my hand, it will be time for you to leave, little Grasshopper.

You know, I've never understood why Dude didn't just draw a weapon, shoot the master, and then take the pebble from his cold, dead hand. Seems like it would just have been easier...

OK, stud, grab your brass and put your hand out...

Specs and Tolerances

FroHickey the Young Jedi Knight asked:

Um... if the parts are all within spec, but the tolerance stackup was making the pistol not work, doesn't that mean that the specs are wrong to begin with?

Very good observation and spot on...(This guy's got potential)

The individual parts in question were all within tolerance spec, but just barely so. All of them together stacked up until the GROUP was OUT of spec...but since I didn't see the problem, right off the bat, I checked each one alone instead of considering the group as a whole. Mistake.

Tolerances have a plus/minus and can be at either on the low or high end of that tolerance and still be in-spec. When the combination stacks up in the wrong direction, then there could be a problem.

F'rinstance...Frame raceways ways are as wide as possible, but within spec. Slide rails are as narrow as possible, but still within spec. You are
gonna have a very tight slide to frame fit. At that point, just .001 inch
out of spec on either one will require lapping before the slide will move.
Go in the opposite direction, and the fit will be sloppy loose...even though
the clearance is within allowable spec.

To put that .001 inch in perspective, an average sheet of 20-bond typing paper is about .005 thick. Not much. Now consider that a very good dial caliper is only accurate to a .002 inch tolerance...plus/minus .001 inch, and
you can see how a little thing can be missed. And...It's the LITTLE things
that getcha.

Cheers all!

Kaylee!

You were the only one who caught that important clue...or at least the
only one who said so...Color ME impressed. You go girl!

As we were bangin' our heads tryin' to figger this thing out...about 4 hours
into the thing, the owner said: "By the way, that's not the stock MSH.
I changed it just before this problem started."....
That's when I started lookin' closer...and that's when I noticed the "Dead Hammer."

I thought about shootin' him, but discretion got the better of me.

Kaylee...Nobody calls me "Mr." except traffic cops and used car salesmen...
and when I hear it, I know that it's gonna cost me money...

Kaylee.....
See - you joined in sooner.
I ruled out the MSPG housing only because I understood [I thought] from reading "still in spec" and did the same thing before MSPG swapped out.

I get in to trouble when I think...that was how I read the original post.

Since I don't know ( obviously) if the leade is not enough, or a lead build up from 200grSWC, "just a smidgen" will not everything operate - still allowing a flat primer?
