Do you use a parting tool to cut off your barrel?

[geo.ulrich]

I cant argue with that. I will keep bandsawing and you keep parting, no worries. If I ever get the opportunity to have some testing done so far as grain structure I'll share the results. I know a guy that can probably help with that. It may turn out to be a non-issue. Would not be the first time I was wrong, and Im ok with being wrong

Alex, I don't think its so much about being wrong then being misinformed, if you need something ground for testing let me know. ground then they will acid etch to magnify is what they should want .....

Anybody ever use a hacksaw while the muzzle is in the lathe? it's not a clean cut, but facing would take care of that.

Tried once took more elbow grease than I would want to give on any regular basis. And woul be easy to be more crooked than the .100 needed to clean up a parting cut. So way harder for little gain. But it will work

That's hilarious ! If I ever get crazy and build a home barrel drill/rifling machine I know what I'll be using to learn with .

I have a piece of 1.25" 100ksi rebar used in security installations that I is pretty tough. hmmmm. --Jerry

 

[msinc]

Re-bar is tough, no argument...but it has a lot of inclusions and what appears to be trash and air bubbles within the bar itself. If you have ever scoped a Ruger barrel you will understand exactly why I made the Ruger using it comment. As far as really making a barrel out of it???? Well, you can drive your car with your feet if you want to, even part a barrel with a hammer and cold chisel.......but that don't make either one a good idea!!!!!!

I have been reading the post very interesting to say the least George Ulrich ask me about parting off I don't do my machining like the most of you do I part off in a steady rest with a tool ground to eliminate chatter I like a nice chip rolling off if a barrel is heavier than I like I set up in steady rest go to the bandsaw cut off a little l long an face off the barrel an reset up the steady rest an finish crowning if a gun barrel is stressed relieved properly the bore will not open up very informative post to say the least.

Band saw, parting tools and I don't get along anyway!

Did a small, simple test. Parted off about 4" of a muzzle awhile back. Found it laying around and it had the normal huge part off burr on it. Took that, chucked it up and faced less than .010" off just to clean up. Found a snug fit reamer bushing and attached it to a grizzly rod. Pushed it through from end to end and did not change the feel when exiting the parted end. No tight or loose spots. Consistent feel all the way through.

 

[carlsbad]

Experimental results are how we validate theories. I'm birthing a barrel today in honor of Independence day and my bandsaw is unavailable. As a result of this thread I did change my way of parting. I parted first in the chuck with a very sharp parting tool and a slow feed rate, faced off .015, then made several small cleanup passes until I had the clean cut lands I wanted. Hit with emery paper, took my tight bushing and checked it. Ready for chambering. After I chamber, I will reverse and align for the threads and proper crowning.

This thread has definitely raised my awareness of this important issue.

I use a parting tool and may have just found here with this thread why friends groups are getting fliers. Gabe22BR shot a 600 yd match with me this weekend and would have had a new unofficial world record had I not been parting off my barrels .

and this is the rest of the story

Thanks guys for this valuable info, keep it up!!!

Well it could have not been the wind is your friend or the loose nut on the end of the stock lol great job Tim I think you did your part

 

[Will Henry]

I know of a barrel which was made of a piece of re-bar. This was made by Ron Smith in Alberta as a bit of a joke and it shot very well. Ron is a pretty talented barrel maker. WH

Yep, was the crazy nut behind the stock, trying to read the wind...

I know being close minded to anything will only hold you back. Records from just 10 years ago seem big now. Things keep improving, but the "its always worked for me" mentality is not whats driving it.
I guess what Im saying is I have seen horrendous work that still shot at the record level. Sometimes things work in spite of us, not because of us. I think discussions like this are important.

The discussions I treasure, are from using on many projects, the top smiths in the country. These include Dwight Scott, Jim Borden, and last but surely not least Mike Davis. What a fine cast, and I am but a shadow, and fantastic listener. It has proven valuable beyond imagination. Mike could answer questions, that neither of the others could on correct brass prep. He knew of my interest to purchase a lathe. He shot long range where the others didnt. There are no smiths here I put on their level.

Almost forgot the Smith that planted the seed in me for choice of lathe. When Speedy took the job in Colorado, he listed his shop equipment, he owned 2 South Bend Heavy 10 lathes and decided then if I could ever own a lathe, that would be the one. Have since learned the great Seely Masker owned 3 of these fine machines.
