gbull thanks for the diagram, I chambered the barrels last night and used .043 for the head space. I\'m still making parts but at a slower pace than I had hoped for. I finished the bolts and used cutters latest extractor version, I think he got the idea from the 10-22 extractor. I have to thank cutter again for the help and information he has given me during this build. He very kindly loaned me a jig to machine the bolts for the extractors and even loaned me a completed bolt to copy from. Thanks cutter that jig works great.
The bolts are now completed and the notches are cut is the rear barrel plate and the barrels for the extractor clearance. I tested the extractors by removing the firing pin from a couple of bolts, setting the bolt carrier on top of the rear plate while the barrel group was vertical and dropping a couple shells in the barrels. The extractors worked well and extracted the shells when I pulled the bolts back.
The box cam installation is complete in the brass cam carrier and the flats are milled on the sides. Some of the frame parts are complete but not assembled yet. I\'m still plugging away and one of these days there will be some shells put through it. Here are a couple of pictures of the progress.
Have a good one.
Dwight
