Got the forearm tip added. Continuing to work on the forearm attachment mechanism, which includes the placement of the rear sight base because the forearm attachment is part of the sight base. Here is a pic of the forearm tip

As I work on the barrel attachment I decided I wanted to make a small spanner wrench that can assist with seating the barrel and also removing it. It will be stored in the buttstock under the trap butt plate. We own a small VMC that my son uses to make products for his camera accessories business and also his high power rocket accessories business. So he machined out the profile for me, now I will finish it. Second pic give a size reference

I have a similar spanner that came with my Ballard-Pope takedown set. Mine is just cut out from a piece of 1/8" steel.

Progress has been slow for various reason. However, I have now finished all the metal to wood fitting, (or at least I think so) with the trap butt plate. It is cast off 1/4" with additional 1/4" toe out

Cut the mortise in the butt stock under the trap for the spanner wrench. At its deepest the mortise is 1/4 x 3/4 x 3 1/2" deep. And may I add into walnut end grain. below are a couple pics (note: the screw will be machined to be the pin portion of the wrench and only stick out about 1/8" when done)
I need to consider how and what to line with under the trap door and down into the mortise

That is really looking good, is that a Biessen trapdoor butt plate?

Need to make the rear express sight base. It also needs to add a locking feature on the bottom of the barrel which will serve as a forearm attachment. The trick of this is to bore a tapered hole that will fit perfectly with the taper of the barrel. To do this (first 2 pictures) shows how I setup the lathe taper attachment so that I can bore a perfect match. I used the barrel itself as a pattern for the required taper.

The next 2 show first rough drilling the the work piece and then boring the tapered hole using the taper attachment

Last pic shows the material slide onto the barrel. Turned out very well. I will now start milling it as required using the mill with its vise and also the dividing head.

If I could be so bold, why taper bore it and not just turn the barrel? I assume you will solder it in place?

You can do it that way but since I have the equipment to taper the mount I chose to do it with that equipment. I will also use the setup to make the front sling attachment and front sight band.
