Cutting and Crowning a short barrel

[shortgrass]

I want one!

All it takes is time and material! "theyard.com" for aluminum. Steel would be better, as ridgeway mentioned.

This. I always tell customers with oddball jobs, or jobs I am not tooled and schooled in, that at the end of the day we both need to be happy. This usually equates to money. Sometimes even if the money is right, if it is a pain I pass.

Make it out of carbon steel...you will thank me later

Aluminum ones work for me. I got 2 of them. A titanium one would be nice

I don't take every job that someone wants done, maybe turn away more than I take. But, I always explain why to the customer. Could be time, cost, lack of experience, or just something I don't want to do. I also try to steer them to someone who will do it, or to the info so they can do it themselves. As an example, glass bedding, my ocd kicks in and it takes me way longer to do than makes sense for somebody to pay me.

I still remember old TJ used to tell me when I hung out at his shop "I don't do furniture"

Naa...it won't be that bad. Aluminum is nice, will get ya by, but steel is my choice. I guess when you deal with heavy parts on daily basis, you tend to design with ridgity and longevity in mind.

The only thing stronger than steel is MORE STEEL!

I wish I had a picture of the birds nest of chips that came out of it. I think it was 3 full trash bags.

Aluminum is produced by machining aluminum. If you start with a cubic inch of aluminum, and machine it correctly, you could probably create enough aluminum to keep Budweiser supplied for a decade.

If made of steel, it would not need the diameter that one made of aluminum would. Start with thick walled tubing. It's out there, it's just a matter of finding it. 4" xxh pipe has a wall thickness of .674 according to my pipe chart. 3" xx has .6 wall. According to API standards I think I remember the material is C1044/C1045, also known as "stress proof". There is such a thing a xxx and quad x , but it's rarely seen in the 3"-4" diameters.

I started with 6-inch aluminum so it could bolt up to a D1-5 backplate.

I’m guessing I miss read, but do I understand you to say they make a stress proof tubing? The stressproof I use is 1144 TG&P in the solid form.

Pipe for well hook-ups (surface equipment plumbing) is made of C1044/C1045. Pipe. I think tubing can be purchased in many different grades. Tubing-Pipe,,, 2 different things. We get cold drawn round bar specified as "stress proof" C1144, used in some 'job shop' applications for repairs.

We did a lot of frame parts and swingers made from 4130 chrome
moly tubing. You could make it stiff and very light at the same time.

Nice piece! We use a Viper jig in the 4 jaw but you created a masterpiece sir

 

[LVLAaron]

You can't get these, but this is the design I borrowed.

 

[WindSurgeon]

Thanks to all. I found another gunsmith locally that cam recommended and described what and how he will do it and has the tools. I'm visiting his shop this week to go over it.

Wow!!!! That is fine!!!!

I take an old railgun barrel and make it into a fake action. You can put it in your normal spider setup then
