This is a repost from another forum that a member here asked me to share here. There is a 10 pic limit so I'll have to break this down into two posts.

Ok, IIRC I left off with ordering a section of T3 aluminum and finishing the internals. Well, the T3 aluminum showed up and it sure looks strange compared to the T6 I'm used to. It has a kind of sheen to it that changes color depending on the angle you look at it. It seems to shift from a purple sheen to Fuchsia. Looks kind of sci-fi to me. Here is a pic but it does not do it justice of what it looks like in person. VERY strange.

OK so after cutting down the new T3 tube to 15.5 inches and threading it I made the cutters to cut out the polyurethane baffles. I'll need to make two cutters for two different sizes. Three large ones will go in the tube and two smaller ones will go in the endcap. The large cutter I made from some left over section of the stainless steel tubing.

Wow that stainless was HARD to cut down. This is just a matter of taking down the outside at a nice angle and boring out a bit from the inside to make sure that when the baffle is cut it fits nice and snug.

The last part is to sharpen the cutting edge. I use a file first, then finer and finer sand paper, then finish it off with stones. Gets damn sharp, and yes I've cut myself a few times miss-handling them.

Now I needed something to make the smaller cutter out of. Off to the scrap pile.

Note: BEWARE the scrap pile.

Unfortunately I did not find anything that would work. I ran into the same problem with the Mauser project and wound up ordering some extra thick high pressure tubing. I was hoping to avoid that this time so off to Lowe's I went.
I picked up a couple of "couplers" that seemed like they may work. A 1/2 inch to 1 1/4 inch couple seemed to work ok.

And another mock-up to show all the internals with the tube.
