    What is going to be the orientation of the MACs in the mount? Mags straight up, down, or to the side? Seems like if the are sideways you wouldnít have to worry about ejection as much since one would eject up and one down. I think thatís how the old M1 carbine dual mounts were orientated.

    Magazines up! Again, mirroring the VP. This was cleanest- only hang up for this option was clearance for ejected shells but weíre good to go.

    First piece of mount / grips platform done- going to clean it up and size the other parts.

    Post clean up and sizing. Clean up means filing away all the bits and edges from plasma cutting then filing it drilling holes clean/ to size. Each one of these will be a unique hand made piece!

    Does the plasma cutter guy live next door?

    I would be broke if a cnc laser guy lived next door.

    I’m very lucky- almost!

    Community Workshop: 2.9 miles away, open every day 7am to 11pm “Like a gym, but for people who build stuff”

    This has enabled me to produce parts in under 48 hours from model to cleaned up piece. I’m making a lot of parts now!

    Another drawing, front sight piece. Made the barrel holes .25 so I could align em and drill the .5 holes myself.

    Nice fit, thread protectors will pin this back on both barrels, may integrate some barrel shrouds as well. Remaining grip parts submitted.. once complete, I will have all the parts on hand and can Assemble this monster.

    This is like when George R.R. Martin says he's working on other projects instead of finishing Game of Thrones ;-)

    The 12 gauge is full speed ahead, donít worry- itís just out of my hands for now and this seemed like a fun idea. I wasnít going to just sit on this while I waited!

    Spade grip parts are in queue for cutting as of last night. Weíve come to the part of the project where Iíve done all I can at the moment. Waiting on parts to be cut, waiting on a part at the shop, waiting on parts in the mail. When each of those come through, assembly can begin. Turning to router assembly so we can work on a dummy bolt and wood furniture test piece for the shotgun upper.

    For sure, they could be mounted and configured in almost any way. But spade grips are better. And Iíd like to make a second grip/ stock so the whole thing can be shouldered...
