maybe welding them together just might add enough length that you need, before grinding them level.

been busy drilling and tapping pilot holes, brazed the tips of the triggers to fix them being undersized


breechblock





after I solder the breechblock on, I need to come up with a way to hold my lathes knurling tool in the mill spindle and make the spurs on the hammers.. and can forsee a few problems, but try to also knurl a piece of bar stock to use as a barrel rib

Well I now have a piece of flat stock knurled for the hammer spurs,  arms feel like they are going to fall off from turning those mill feeds with that much downwards pressure, don't think I can do 17inches of this for the barrels and survive.  This was the first time I've ever seen the clamps on my spindles angle adjustment slip before. honestly scared me I Shouldn't continue. 

there isn't a local source for this is there? like lowes/homedepot.. even considered anealing a file and using that for the hammer spurs.  Does anyone have a preference on sight ribs being diamond knurled/horizontal/vertical striped, or I have a revolver that is just simply flat but sandblasted. they are supposed to stop glare

I think a file might eat your thumb if you used it for a hammer spur, but might be ok if quite heavy for a sight rib.

Hacksaw blades seem to get used in gunmaking a LOT.  There's an AR bullpup with the trigger linkage being a hacksaw.

while working on it, I've been testing those hacksaw blade-plungers alot.. and the spring tension tends to bend them outward (which will later be stopped by the stock) which I originally thought that bending would cause failure in the hacksawblades. but maybe because I hit them with the blowtorch to anneal them or just me being wrong. there are no signs of failure under extreme conditions. hurray

Decided to get fancy and add a captive pin for removing the barrels like the ar-15's have. so to break the rifle down for transport takes only the tip of a bullet


added some round endpieces to add meat for the grip screw. will probably extend this section in my cad drawing If I ever have more laser-cut. also sanded everything~


cut that section out of the hammers and soldered a pin for the pushrods and the spurs. cut that section out of the triggers for their springs. and started making the hinge/ejector part of the barrels

Looking very nice

The last time I did any knurling on a mill, I made up a fixture, with a slot cut for the piece to sit in and clamped the piece together with the fixture to the table.
The slot terminated and formed a stop so the part would not slip.

Yeah it's extra work but it saves the clamps from slipping.

Thanks for the advice, but I meant the angle of the mill head moved on me, scared me I might break something for a few minutes.. but it is a strong mill and everything looks fine.. probably just backlash between the worm gear for rotating the head.  The next attempt after that I did 1/8" passes instead of the full width and had no problems

What mill have you got? Out of curiosity.
I'm thinking about a second mill, with a longer X axis travel, and more capacity to do larger assemblies etc.

I hope I didn't try teaching you to suck eggs, not the intention.

oh I thought I posted a picture.. the barrels are 22lr liners soldered into 5/16x1/2" tubing and then soldered together. I still have two 6" pieces left over from the original 22" liner for the pistol shaped pieces I also had laser cut

Wow, thank you. While trying to figure out what material to make the butt pad from and going through pictures of black powder guns with solid brass pads, I have been playing around with the idea of adding a patch box to the stock.  But, after spending a few hours shaping the stock I don't have the courage to put dents into it clamping it in the mill.. who votes that I add one to hold... cartridges or cleaning supplies or gold doubloons or whatever

can add firing pins now

and about the pistol.. I think I'll do 6inch barrels like the first set I made and later destroyed from over polishing







also it was an after thought and will be refined on the pistol, but I made the ejector spring inward to stop friends from slamming the action shut without pressing it in and bending it...again
 (thats why the first pistol has a ramped section now)
