Making a Sharps Barrel in my lathe.

Hi Homebrew,
do you think it would be safe to run factory loads in a barrel like yours?

Hi B F, If the barrel bore was really good should be no problem with a good proof test load. I`m only making barrels on my lathe for black powder loads or equivalent ones in nitro powder and lead bullets only, more forgiving in a rough barrel as mine is no way perfect and will heat treat both barrel and receiver when finished machining. I have the Lyman load data for classic American calibers and all the loads for the 45-70 are for smokeless powder, but keep the max pressure to 28,000 cup. So I will be loading black powder and 405gr bullets and watching the "ouch" bit on my shoulder, :ouch...it hurts:, Homebrew.357.

:killzonesmiley: Hell, with all this holy stuff around you need a gas mask on and a knife to cut the air. Speaking of cutting , there`s a pic of some real action cutting the octagonal so you know I`m not pulling your wiser. It getting there, have done 4 sides so far. Homebrew.357.
Attachment 32077, Cutter shaving off a nice curl from the barrel and a pile from a few passes , the trik is to keep the cutter sharp.

I am in awe of you! You have done what I have been wanting to do only I only wanted to re-bore shot out 303 barrels to 357. I was thinking of using the feed to drive the rifling cutter at a different speed to the chuck so as to achieve the rifling twist desired. Anyway, I didn't get that far. But you have inspired me and given me some ideas.

Regarding the question of whether your barrel would be safe with factory loads, I would say absolutely.

Are you planning on shooting only naked cast bullets or do you have paper patching in mind? There are folks shooting paper patched 45-70's with stunning accuracy at ridiculous ranges. Think 800 yds with all ten shots in the centre of the gong. The centre is a bit bigger than a tennis ball but still. I'm guessing about a meter diameter, maybe smaller.

Hi .303 guy, I suppose there`s a lot of ways of doing this , like a sine ways rifling bar, just have to look on the internet for ideas. I just got lucky with my gearbox and bike bits , and the end result is allways different to what you think, I was going for a twist of 1-18" and through I had it, but no it came out 1-20" so it will have to do. Now the barrel is cut octagonal and stopped short at the breech end so I could grind the tulip bit that the Sharps barrel has at the breech end . Now all I`v got to do is polish and clean her up and at this stage will get it heat treated , but after xmas, I`m having a holiday, cheers, Homebrew.357.:thumbsup: Attachment 32290, Octagonal done. Attachment 32292, A raw Sharps Octagonal barrel, hope it shots strait.
Attachment 32288, Grinding the tulip . Attachment 32289, Bit of a polish should help.

Hey at least with those flats cut on it you can hold it in the vice real good :thumbsup:

You deserve one.

go enjoy your xmas break homebrew ,cause as said hell have you earned it and boy has this been an amazing thread to follow!

Hi Guys, Hope you had a good xmas and put a dent in the brown ale supply, I need three homebrew kits at least to stock up my supply. Have done a bit more to my Sharps barrel, octagonal finished and have cleaned up the breech end ready for thread cutting, it will be 1.5 metric thread , and have cut the muzzle crown , looking good. The block of 4140 has arrived for the receiver , so will be farming that out for cutting the breech block hole and for something to do I have made a double cavity mould with to ali blocks , weight range, .430/45 I think, won`t know till I do some casting. :beer: Cheers, Homebrew.357.
Attachment 33691, 4140 block. Attachment 33692, breech end tulip. Attachment 33693, ready for thread. Attachment 33694, nice crown on muzzle.
Attachment 33695, ali blocks for mould. Attachment 33696, have to see what thay cast.

Just couldn`t stand the suspense of not knowing what my new mould would cast out at, so had a bit of lead casting today. Results, .463"dia, and the double cavity mould cast one at 425grs, and one at 406grs, so all in all not to bad, now will just have to wait till the Sharps is finished to see how they shoot. :o :XD:, Carn`t stand the suspense.:thumbsup:,Homebrew.357. Attachment 33760

Don't think we can either :)

Well you will have to wait guys, I have just got my call up for my final hip op, about six weeks on crutches and sitting around. I know, will look at making a gun cover with bead work on it, Cheers, Homebrew.357.
Attachment 34357, Something like this.

Hi homebrew.357
I just read your thread on this build on practical machinist-a even better read than this thread.
I look forward to seeing the progress once your back on your feet.

all the best with your opHB and hope ya recovery is as just as quick.will be thinkin of ya.

Hi RES, Yes I have posted this build on two US forums, they couldn`t believe it as well, so the Hawken and the Sharps build is on (Practical machinist and The home machinist forums in the US, you have found me out, but give you some more to read, just look for Homebrew.357 in the gun smithing section. I tell you guys when this hip op is done will be running it in so I can get back in the bush for a hunt, Cheers, Homebrew.357.
