Gas delay has been used on one of the best suppressed pistol ever. The H&K P9S plus the P-7,P-13 and the mighty desert eagle use gas delay. I wish more major caliber pistols used frame mounts as barrels are easy to build and no Nielsen device is needed. If you are having problems getting a barr...

To error is human! We all do it, Weather you are an old-timer or a newbie. So lets turn this into a teaching moment. 1. 90% of machining is set up. Old machines have backlash, tolerances stack due to wear. Check and recheck before cutting 2. SWAG doesn’t work in finish machining! SWAG= Scientific wi...

Looks like a fun project. Thanks for the update!

HaHa! You got me thinking about making a Die Filer, It wouldn’t be hard to make one or change the shaper into a horizontal one. On the shaper you would only need to remove the clapper and install a clamping block for the file. Yeah that would certainly make a stout die filer! Way better than using ...

West of Texas State in the hill country. In Houston’s vacation spot. I picked up the shaper 6 years ago from a older guy north of Houston who had a crane repair business. He had a bigger one and didn’t need it anymore. He had a nice shop I was jealous! LA and the east coast have all the good machine...

Is the chamber fluted? Does the barrel have a flat or splines where it interfaces with the frame? If it does, that would make it easy to keep the barrel bleed hole lined up with the frame hole when pressing in the barrel. I’m a older shooter. Was thinking of myself when I wrote that. The idea of ri...

Well I just ordered 2 (the last 2) of these chambered barrel blanks. https://chaszel.com/product/9mm-heavy-barrel-blanks/ Two chances to get it right. The one I linked to earlier was less money for more barrel blank, but it wasn't chambered. I didn't realize chamber reamers were so expensive. If I ...

The gas bleeding into the lower chamber creates a secondary variable pneumatic recoil spring so the primary coil spring can be lighter. As the the bullet moves down the barrel the pressure reduces in the gas chamber until the piston cuts the vent off. I would think that the system would work equally...
