1911 Frame

NEED SOME ADVICE!

Hello Guys,
I'm working on a custom 1911 that I'm building myself and am doing some smoothing and slight weight shaving on the steel frame.

Where exactly do these pistols frames usually due to stress, so that I will not bother areas that might affect this?

Thanks in advance for your help and advice!

It's me again.
My internet protection software bleeps out certain words like - - . That's why I usually say piece or pistol.

What I was referring to in this post was frame - - - - - .
 
Well it's still doing it even w/ dashes between the letters.
What I'm refering to is little hairline openings in metal caused by stress. The same stuff dumb people smoke!
 
If I had internet protection software that wouldn't let me type the word "crack" or "gun" I think I would be unloading some software.

"He took his glue GUN and fixed the CRACK in the door to the DRUG store in FishKILL, New York." ;)

In reference to your post, I am sorry, but I do not know where the stress points are.
 
Around the cutout for teh slidestop. Left side of the frame, along the rails.

BTW, does your sofeware also act up when you inquire about or use words pretaining to the human body?

I agree with Jim V. Most points where cracks initiate and propagate are design cuts in the structure (such as holes through the structure or areas with the structural cross-section has been reduced).

However, there is an interesting phenomenon about crack initiation and propagation in metals -- even steel forgings and castings. The loads applied to a structure are transmitted throughout. Therefore, loads will always seek weak point(s) and if the weakness is sufficient, a crack will initiate.

While the 1911A1 slide assembly has inherently weaker design points (not to say they are sufficiently weak to cause crack initiation under normal use, loads, and stresses), one can create a point for crack initiation and a path for crack propagation if one modifies the structure too greatly. Accordingly, I respectfully suggest you exercise care in "whittling" away structure -- particularly proximate to any design feature that creates a reduced structural cross-section.

Incidentally, this is why the use of "hot rounds" (beyond the manufacture's specifications) is not a good idea. When loads and stresses simply become too great for the structure, crack(s) will always initiation in metallics.
 
Thanks for the responses, guys.

Jim V, yes it does also negate references to certain body parts as the software is designed to keep pornography out of our home. I'm going to have to figure out how to override the firearms deletions, though.

RWK, being an engineer I understand and appreciate your points. I will indeed be very careful and I also dont believe in "hot rod" loads. I only have arms that I like, not ones I want to blow up.

Thanks,
Dave
