Did mine and posted bad pics earlier. Still trying to decide on how to fill the two unthreaded holes so I haven't actually used it yet. I think I may go with the solder method you used, and if it works I may even fill the threaded holes that way just for cleaner looks. Also considered a few other methods like press fitting some SS rod or marine grade rivets. Ruled out rivets because you don't want to interfere with the center post in any way.
I don't have another mod beside the Paps that this will fit either although for a minute I got really excited thinking it might go on my P+. Alas, it did not...
Thanks for the pics.
The solder was a pain, not sure it so much adhered to the ss as much as made a zero tolerance/perfect fit plug.
Eventually I ended up filling the solder from the underside of the too plate while it rested flat on a tin lid, otherwise the solder just fell out all the time , especially doing two seperate holes. The flux was a little bit of a pain to clean off and the surface of the ss discoulored in a few places due to all the experimenting, and needed more sanding and polishing of the the knurled area to hide the visible signs of this. Sanding the solder back to a nice smooth surface was easy though.
If I was doing this over I would definately fill the holes first before any sanding or polishing of the knurling.
It was pointed out to me that the knurling on the bottom of the AGA-T kinda matches the Paps locking ring, and with a bit of a sand and polish it gets closer still.
Keen to see one of these fully deknurled though, and how big the resulting step would appear.
