Hope you didn\'t pay the big bucks for it.   A guy on ebay has 4\" rounds in many lengths.    I got a 4\" round 4 inch long for $60 with free ship from him.


 


Thats STILL a lot of money,   geesh brass is expensive now,   all metals for that matter.




 


 


4\" diameter with free shipping , probably the same guy from eBay

That’s about par for the course on my saw. I’m actually surprised when it decides to cut something true

Cutter,


 Was that a Harber Freight saw by any chance?

Not sure the brand, I used a friends saw.

I think the material moved, so I didn’t clamp tight enough.

 

eBay is only a click away.

Cut a shaft today for alignment/inspection.

Starting popping in holes next, wish it was that easy.

Hello Cutter and everyone else, I don\'t know if I mentioned this in my few posts.


I am machining almost everything in steel with plans to either electroplate or brass metal spray


the appropriate exterior parts. I have the equipment to do both, just need practice to get it right.


If anyone wants to do the same, I will gladly let any forum member who can make it to Golden Valley, AZ


use my equipment.


Another possible method is to rub a heated spinning part with a piece of brass, as per YouTube.

Stirlingking,


  


That is interesting stuff. Can you do chrome plating also?

It is vegetable season here in the south west and there have been tractors working the fields down range from my shooting area. I have been seriously thinking about firing up the back hoe and digging a below ground shooting range. The only problem is that it takes up quite a bit of real-estate unless it is deeper and then cover it back up afterwards. I guess that it would make for a good bomb shelter if needed but it would probably be a great place for rattle snakes to move into also.

Over the last couple years, I cleared a couple acres of woods and made more grass to mow.    The hardwoods I gave to a friend who burns wood and I took the pines and made a big pile in the back of the lot as a backstop.   I dumped dirt and debris on top which holds things in place and fills any gaps.   The pile is about 30ft wide, 8ft high and a good 6-8ft deep in the center.

Bruski: a couple subjects to cover. One at a time. Underground shooting range:


Have you considered digging a large pit to about chest level and laying one or more


lengths of 2\' to 3\' diameter pipe, plastic, cardboard, or whatever.


Leave a walkway on both ends of the pipe(s), bury the pipe(s) and put a roof over the walkways


(for subterranean).


Install lighting, place targets in one walkway and the shooter on the other end.


I have been racking my brain for years trying to think of ways to build underground for cheap, not


have the sand cave in, and my neighbors not seeing me doing it.


Hope that makes sense. -Stirlingking

Are you using a commercial thread mill?    Some use a tap with all but one flute ground off I hear.


 


Will any barrel fit any hole AFTER the extractor reliefs are cut?

Jerry,

Looking good. Did you blue the barrels? Or did you have someone hot blue them?

Yes, a commercial thread mill ( image )

Also Yes, with a thread mill , the thread can be started at anywhere on the circle.

Mine all start at the zero position, where the extractor goes.

 

Fun Stuff Huh ??

I made up the recoil plate and rear cover recently.    I still have to make the holes in the rear cover for the bolts and cocking switch.  


 


Any ideas for methods / alternatives for holding the cocking switch back,  other than the RGG method with 3 pins?
