Re: Making a sharps barrel in my lathe.
Thing`s were going good, have done three passes a long the barrel, so resharpened cutting bit and away for the forth cut, the gremlins had put a spanner in, Chattering, my fillings where rattling, What`s wrong , I checked it all and could not find any thing wrong. Had a think, wont`s changed, I remembered the cutter had small flat at the tip from sharping , could that be doing it. So recut and set up again, fingers X, yep, sweet as, well there you go, you learn things by doing it. I will not grind the od , will try my shaving way, and seeing it`s set up for that and it worked for my Hawken barrel , so should be ok. I can not put a follower at the back of the barrel, I`m cutting a taper with tail stock off centre, the front side is true to the lathe bed, so you carn`t use one. There will be some spring when cutting the octagonal, same as my Hawken barrel, it`s fat a bit in the middle , just make the barrel stronger. Will make a round disc to fit my rifling register with eight holes for cutting the octagonal and when doing it I only cut half the flat with the cutter, to hard to cut in one go. Cheers guys, keep your fire going over there. Homebrew.357.

Re: Making a sharps barrel in my lathe.
I like the approach of getting the job done with the tools at hand. I will look foreward to the using the lathe as a shaper to cur the flats. or you could go old time and draw file the flats. build up the arms for sure!

Re: Making a sharps barrel in my lathe.
Hi Hammermill, No will not draw file it, or shave cut it, I just realised I have to chamber it first while it is still round for a good datum point, so will be setting up to do this and will be doing it very slowly . Will lathe out as much as I can and then try my chamber reamer I made, but have to harden it first and I made it with no throat end, yes I do make mistakes, so will have to make up a D bit for this at .458" dia .

Re: Making a sharps barrel in my lathe.
Hi all, as you can see I`m really doing this in a back yard way, but because I have no precision measuring other than my T.D.I and micrometer, and as I said I will get the breech block and the hole for it done at a tool shop as I don`t want to stuff things ups. All so, I made a chamber reamer, but with no throat or lead, so again as not to stuff things up has anyone got a spare 45-70 reamer I could borrow for a while, just to do this one job, I would pay for postage here and when finished send it back to you in the US . I would get a better job with the right gear. Cheers, Homebrew.357.

Re: Making a sharps barrel in my lathe.
Yes you are right, must show nz dollars, I thought that was US dollars. Gave David Manson a buzz, finish reamer, us $110 ,p/s, he said it would do the whole job, back to a rock and a hard place. Mite have to look at tool makers over here and when the job is done I could sell it, as it`s only for one job. Cheers, and keep warm over there. Homebrew.357.

Re: Making a sharps barrel in my lathe.
Hi, While I`m waiting for the block of 4140 steel for the receiver had a go at making a resizing die for 45-70 , so using a t/c cutter and setting the top slide over a bit for the case taper, just feed in the top slide with the hand wheel and fine cuts to take out the spring it came out good. I used a new case to set up and the slight taper is not hard to machine , so I have new die for the 45-70.
So why am I looking at chamber reamers for , when I can just machine it, , guess what I`m doing. Homebrew.357.

Re: Making a sharps barrel in my lathe.
Hi Hammermill and Redneck, Yer, It takes a bit for the old brain to click in, after I finished the sizing die had a glass of my brew and bingo, I thought I have all ready made a chamber with the flaming die. Mind you it is done to s a a m I specks for the 45-70, but my be a bit tighter and no lead in to the rifling, just a 5-7 degree slope and a loaded case fits in nice and snug . Had to take a snig more out for the case rim to fit as they very in size a bit , so now I have a 45-70 chambered Sharps barrel and just need to make it octagonal . .Homebrew.357.
