1903A1 Action Wrench and Vise Jaw Special Drawings

[rcathey]

Bill,

Couple thoughts so far.

The plates that take the hardwood inserts to hold the barrel indicate a groove of 1.469" wide to hold a 1.490" wide insert. They call it a "press fit" but, 1 - that ain't a press fit and, 2 - I don't see why it would need one. I'd just make that groove match your inserts (or vice versa).

Looks like you've covered a dimension with your yellow cloud on the hardwood insert. The big end looks to be .955" diameter and I THINK the small end says .825" but it's covered.
Also, on that subject, it appears to me that they've drawn the two ends non-concentric. I can't imagine why they'd go that route but the center points are offset by .0625". Weird. Why not concentric?

Comments so far?

That picture was one I was trying to work-up with a friend but we were lost on a few of the dimensions. I got the original drawings from another fantastic user on here in the group. I don't know if he's ok with me using his name so I won't publish it. Anyhow, here are the JPG. without the edits, we put in. Might clear things up.

Looks like I guessed wrong on that dimension for the wooden insert.
And now I see what it's saying. It's saying that the centerpoint for BOTH circle is 1/16" above the surface of the wood. That makes much more sense. I've attached an updated drawing.

I still don't get the interference fit between the wooden insert and the clamping plates. A 1.490" wide block isn't gonna fit into a 1.469" wide groove!

And again, I can save these in any format you need. Just let me know and shoot me your email address. I'll send them over.

Home from work and time to read your post. I looked at the drawings in Brophey's book and it has the same measurements. says press fit but, that's one heck of a press fit. Even with the - .010 it's still a .011" difference. Guess I'll find out when I get it made and use it.

Thanks, for the help!

It's good to have connections!
The water jet shop I use through work hooked me up. He did a great job. Appears to be very little draft from one side to the next (as would be typical of sloppy or hastily done water jetting).

I had him make it from whatever stock he had on hand so it's aluminum. I think it'll work fine though. If my "Auction Gambling" 1903 ever comes in, we'll find out.

Came out really nice! it's going to be interesting to see how the Aluminum performs. I don't see a provision for a handle, how are you going to crank it?

A big ol’ crescent wrench. I might bolt a handle to it yet though. We’ll see!
But yeah, it did come out quite nice.
