Measurements for Mosely/Marshall inverted punch receiver piece?


Recommended Posts

Since I've finally gotten to cleaning up and refurbishing my C&E Marshall / Mosely staking set, I hoped someone could take a couple measurements for me. My set is missing the tube which receives the bottom end of inverted punches. I have been using a makeshift piece with bolts and nuts in its place and it's time to try to fabricate something better. If you have one of these staking frames, could you measure the outer diameter of the tube and the diameter of whatever is underneath it and connecting it to the frame base?

I believe the 4.7mm hole is slightly eccentric. If you could estimate about how far off center, that would be great too. I imagine it can't be more than a few tenths of a mm. Finally, what is that piece made of? I would not expect hard steel.

I never did find out the size of that piece. I am in the process of assembling a lathe and my first order of business is to make that part (or some approximation) when my 3 jaw chuck comes in. If that does not work out, then yes I may ping you! Welcome to the forum.

I’ve got a few errands to run this morning, but when I get back I’ll grab you some measurements of one of these here. It’s takes just a second to pop them out of the base. I do have extras so if you want one I’ll send it to ya, but either way I’ll grab some measurements for you. I haven’t set up my re-plating station yet, but even then some of these anvils are so damaged that they wouldn’t be worth trying to plate, so I probably have 6-7 extras. 
   The center hole is offset and the back side has a bevel ground into it where it touches the anvil front. I’m assuming this is to make sure you install it so the offset hole to catch the inverted stake is in the correct position.  I took some random photos to try and show the details. As long as you don’t have a little giant anvil it’s offset.  The little giant ones appear to be dead center.

This is so helpful thank you. It looks like I was misjudging that part's function. I assumed it was drilled eccentric so that it could be rotated for alignment like the knurled top piece works. But that bevel means it is fixed in one position.

I measured the horizontal position of the hole on the underside of the die plate where the punch comes through and am surprised to find it is not centered. It's about 1mm offset and I guess that bottom receiver compensates by being off center. What a weird design.
