PMI II

[Heavy_D]

Just picked up a PMI II. My plan is to make something cool with it. so much Inspiration from here, Would certainly like to make a freak insert barrel, and polish the heck out of it, maybe put it into a KP-2 style custom stock.

Does anyone have a source for Brass tubing in canada? online metals shipping isn't cheap for the few pieces ill need. Also any thoughts, input/ opinions on the build appreciated, you guys make some amazing stuff!

Jordan might know where to get materials

I get most of the brass I use from Amazon. Occasionally I need to buy from onlinemetals.com but not if I can help it, shipping is nuts.

For a barrel tip, yeah... but it's too big bore to use as a barrel, 18mm is .708.

I'd been using the .692 tube from onlinemetals.com combined with the 21mm tubing from Amazon, but now that I'm out of that I've used a combo of stock Sheridan barrel tube and the 21mm/19mm tube to make my Freak setups.

Cool thanks for the info, Was just reading one of your other posts, with links to the carbon fiber and brass you use. You build amazing stuff!

The shipping rates even went up here. Its almost $40 shipping for anything longer than a foot

I have ammo tube for sale, but am stateside so shipping would suck. for putting it in wood there's 2 methods, walz's way and traditional c/k series trigger groups, I use the latter

Melted the solder off the feedneck, looks like they unfortunately gouged the receiver with a grinder when they modified the original feed tube. Also fashioned a Valve tool from a 1/2" bolt, worked great!

[Heavy_D]

Got it De soldered and the 5'' freak tube is made from the OG feed tube, just waiting on a brass 21mm ID tube to sheath the back 3/4 of the top tube. Also debating Drilling and taping out the OG hardline for a Macroline fitting.

Very nice! Are you going to do anything with the transfer port between the top and bottom tubes?

[Heavy_D]

well I have to extend it somewhat as the top tube will be thicker, should I enlarge the Diameter as well, from valve chamber up through into the bolt?

[Jordan]

Up to you, really... I typically go with 7/32" (a hair under 1/4") because I drill up through the bottom, then tap it so I can use a setscrew to locate and center the ports in the valve. Gives the air charge a direct route that way.

It seems to help with achieving high enough velocity on compressed air.

[Heavy_D]

great ideas, ill certainly upsize the Diameter
