Does anyone have the Garand d28290-18-SA Trigger Housing and the SA Trigger blueprint or a drawing showing all of the dimensions?
I searched the Forum without luck so far, still working on internet searches.
Thank you in advance.

Bob, Thank you but for what information I need Item Name: Rifle, U.S. Cal .30, M1: Diagrams & Pictures Price: $40.00 is kind of outside what I require. All I really need is these dimensionsQuote:

I can pull the drawings, but the dims are datumed off of different features. The answer wont be .455" or anything like that. Its all tolerance stack.
I need to wait till I get off of work
Jesse, no rush thank you for the help.Quote:

You can see how the way that those particular parts play with each other will have a very wide tolerance.

Check these out.
The dimensions are all datumed from the trigger pin.
In this case the two surfaces (in the blue bubble) can be:
.620-.005" and .74+.020"
Doin the math leaves you at a slot dimension of .120" to .145".
The other details (in green) are even harder cause they are made from radii. These parts were designed to be made and measured and gauged in such a way where they would play nice with each other and nothing else.
Maybe this helped? Also feel free to check my math. Im cutting and pasting on a work break.
(Drawing from 1937)

Jesse, That is exactly what I was looking for, if you have the rest of the drawing I can pull the other measurements I need. Your math is good, I got the same. I bought some demilled stuff and I'm just playing around with it. I'm getting stir crazy at home due to COVID so I find little stuff to toy with.Quote:

Thank you again.
With the ancient D-28290 drawing the number i got was .502-.523".
My dims were from the:
Trigger pin to back of the trigger slot;
Max .710 and Min .690" . This takes into consideration where the front of the slot datums to the trigger pin (.010"+.000-.010")
Hammer pin to the forward surface of the trigger hook engagement slot;
Max 3.205" and Min 3.200"
Tolerance between the hammer and trigger holes of +-.002 on the 1.990" dim.
Please check my math
I'm glad somebody who worked for Winchester took home most of the prints. The latest I have is 1942.
Oh.. the google link didn't work and I never got the other. But thank you for trying I do appreciate it.Quote:

I think that's the safety cut out, I think the trigger cut outis .700 - .701"Quote:

These are all very old drawings though.
Garand, M1, M14, M16, Carbine, 1911, 1917, Militaria, Small Arms is the place to go for prints though. All of it is the most up to date (as one can get anyway).
I have everything of his as relates to the M1.
Now to go machine some grooved lower bands (as soon as I get a concave radius slitting saw).

I was looking at his original "?" dimension that he was looking for.
That trigger slot is .700"-.710" with a positional tolerance of centered with the trigger pin to .010" forward of the trigger pin hole
Attachment 110536
Perfect that will give me the .089 -.090" measurement I need.
I saw that site, bob seijas provided it but since I do plan to go that deep in to the Garand its more information then I would ever need.Quote:

Ah,, I see my mistake. Yeah don't know what I was thinking, it was the slot I was after. Sorry about that, must have had a brain fart.Quote:

:D
I also screwed up another dimension on that last picture. its really bothering me.
This is corrected Attachment 110553
Yeah, it would not have been smart to base my measurements on the dimensions I asked for in the picture since this is a wear point from the trigger guard latch.Quote:

CPC, got what I needed but thank you for the offer :)Quote:

Being in manufacturing they tell me a story. Special interest is with very early prints. I have forged lower band without the groove and lightening cuts as well as the slant cut op-rod
Thanks!
