@Mike8623 , I have included you and @pdentrem on an invite to view and download my gunsmithing .pdf book library.

I've been working on my takedown extensions. Just have to machine the sides a bit to get in my mill straight, then mill the insides a bit then work on the outsides. Mag tubes should be here today.

We'll see how it goes.

Well progressing along. Gonna take those 4 corners off, thinking about that raised divot on the receiver and the recession for it on the takedown plate......but it is all coming along.

I used my belt sander to contour that block!

Thanks for the advice. I'm trying to keep it a rectangle as long as possible so that I can get a good grip in my mill.

What do you think bout that divot. Shape, size, force application etc etc.

 

[pdentrem]

The divot and bump was a fit and try many many times. I used my milling attachment for the divot, the rest was file work. Took awhile!

So the height must be one turn of the threads high...... .050 inch. I'll think bout it tonight before going to sleep. I plan most my day while in bed and before i go to sleep the night before. The takedown extension part will be easy, gotta think how I'll do the counterpart on the receiver.

 

[Mike8623]

The divot and bump......you figure they mainly are for alignment or is their a structural poundage engagement element to it.

 

[pdentrem]

They are the positive stop. So fitment is important. I made the bump fit the divot, as it is easier to remove a small amount at a time then weld in more. Yes you need one turn to clear and a couple thousandths additional as the block has not made a full revolution until it passes the bump, so the bump is less than the .050”. It has no bearing on recoil fortunately.
