    Pneuframe'd Blazer project

    Been thinking about doing this for a long time.

    Walker gave me a sweet deal on a project 1k Blazer that is an ongoing project (got some things planned) and I really didn't like the trigger setup on it - way too stiff compared to what I've become used to - and I thought a pneuframe might be a perfect fix for that, if I could get it to work.

    (Quick sidebar on the frame being used, for anyone not familiar with Trilogy SF frames... they use an electronically controlled solenoid that supplies air to a small actuator, or ram, inside the frame. That actuator moves a bellcrank arrangement inside the frame that drops the sear and moves the timing rod simultaneously, much like any other Cocker frame. The delay needed to make everything work is dialed in with sear lug height and, in some cases, timing rod adjustments.)

    To make the frame work on a Blazer, the biggest obstacles are the lack of externals - the 3way and sear are both mounted to the body and lack any real means of external adjustment, unlike a Cocker - and I didn't want to make any permanent alterations to the Blazer. (Palmers markers are, after all, an endangered species.) That meant all the modifications had to be to the frame, so some careful considerations were made.

    The frame's sear went - no need for it, the Blazer mounts it's sear to the body - and, after some mockups and measuring, a setscrew was installed in the bellcrank to trip the sear.

    The other tricky bit is moving the 3way. Again, no permanent mods to the Blazer, so I had to come up with an alternative to the rod/bellcrank setup PPS uses to connect the 3way to the trigger. So, I improvised. πŸ™‚


    The SF bellcrank was marked and drilled to allow a linkage to connect to it, and then I bent up a linkage out of an old Stroker trigger rod I found in a box of misc stuff. This was mocked up and the length finalized before trimming and final bending happened.

    That left finding a source of LP regulated air to feed the frame... and Blazers have a 1/8"npt port on the back of the Rock housing that works perfectly for mounting a WGP bullet LPR.

    After I'd popped the internals back into the frame, I aired it up, and it all worked, somehow. πŸ™‚ The timing is a bit tight - I'd like a bit more delay between the firing and cocking cycles if I could get it - but I ran out of air before I could verify the tweaks I made to the timing rod, so for now I'll call it done.

    I've done a bit of work to the frame since this picture to pretty it up a bit - I filled all the leftover holes with epoxy and sanded/painted the frame - and there's still some other work to be done to it, like building a Freak-compatible barrel and deciding on what reg to use once I'm finished dialing it in.

    And God turned to Gabriel and said: β€œI shall create a land called Canada of outstanding natural beauty, with majestic mountains soaring with eagles, sparkling lakes abundant with bass and trout, forests full of elk and moose, and rivers stocked with salmon. I shall make the land rich in oil so the inhabitants prosper and call them Canadians, and they shall be praised as the friendliest of all people.”

    β€œBut Lord,” asked Gabriel, β€œIs this not too generous to these Canadians?”

    And God replied, β€œJust wait and see the neighbors I shall inflict upon them."
