Building an historic brass cannon Ep 2 - hand shaping the barrel on my lathe

[Music] all right everyone we bought a really deep hole all the way up through the center of the cannon barrel what it measures out to is around 21 inches we got that board all the way through now the neat thing about it is that we can see the golf ball that's in there with just a little bit of movement just like we wanted that's a good thing that gives us a little room and there's some variations in the golf ball sizes and also it's a little too loose we'll just put a piece of wadding around the ball here's the plan I need to turn this thing around and I need to cut on this end down here I need to turn down for the little ball that's at the breech end of the cannon and kind of get a I'm going to start laying out where I want everything on the cannon I also need to make a plug to go in here this is what we made the pulleys for my kids Christmas presents if you saw that video if not I'll put a link above you can check out that video and it just so happens that this drop piece is going to be big enough to cut a little shouldered plug to go in there that Center drilled and then I'll probably take some some Loctite and Loctite it in there for now that'll give me a center place to work from all right let's give her a try here Wow that's a tight fit that's going to be perfect I'll put a little CA or Loctite in there to hold it in place and then we'll have a center drill to be able to hold the center when we machine on it two more we got it quite a bit of machining down here on this end to do ok so we've taken the cannon bear we've turned it around we've got it on the live Center down here and I've done just a little bit of measuring if you look right down here I put some Dyke and bluing on the barrel this ring which it just scratched by turning it by hand is the point of the drill bit where it should have stopped to give us one inch of barrel thickness all the way around this is one inch this leaves us about one inch 900,000 left just short of two inches I'd like to put a ball of some kind on the end not really sure how I'm going to do that this point is where traditional machining as we know it kind of goes away and I've got to just kind of work the tool and work this in a little bit of an unconventional way because I'm going to wind up turning some of this brass probably by hand some are like what we would do on a wood lathe so pardon me if it doesn't follow the conventional machining methods right now we're going for not necessarily a fit we're going for a look we've got all our fit already done or at least roughed in now we're going to go for the look so I think I'm going to stop right here for now for one reason I want to use this to drive all my work out here on this end I need some way to be able to clamp that in the jaws over here I'm going to leave that and we'll probably wind up before we put our finishing passes on it coming back over here and cleaning this up because all this needs all the handwork done on it what I'm going to do is just do a little shaping to put the crown on this barrel we're going to go over and start doing a little hand shaping using some hand tools I am by no means an expert at this but I've gotten to where I can I can turn I can turn a few parts out fairly nicely this is how they did a lot of a lot of parts back before a lot of mechanization is the hand turned it so here's what's going on we put a little bit of crown on the barrel might come back and touch this up here in a minute we're cutting about 12,000 off the diameter back to the steady rest that's so our shrink fit will fit on there now I'm going to come back and probably cut another ten thousand saw fit so that I have plenty of room to work with here when we get down to final diameter all right well we're many more hours into the machining and what I'm going to attempt to do at this point is do a little hand turning right here try to get a little bit of the tooling marks out of there and then we're going to get a little bit of chatter here I turn that by hand and the tool wanted to chatter because of the the angle that I had to get out to get in there so what I'm going to try to do is work this right here with a mill file just a little bit I'm going to try to real lightly hand turn this out and get hopefully some of that to those tooling marks off because it's a lot to try to sand out of there later I just want to finish this end of the cannon barrel because once this end of the cannon barrel is done the major part of the machining of the barrel is done and we'll have to move on to the next step which is mounting the trunnion rings on here I think what I'm going to do first is I've got a little negative rate carbide cutter in here I'm going to just skim cut this this is a where it got dropped and then we'll come in here with a tool rest will dress this will soften this corner to match these corners like here and then all cannons have some sort of like ball at the end of it night kind of like this but I'm going to do a little something with it I'm just not sure he would I don't know what do you think [Music] so question is do we like it or do we mess with it some more so my answer for tonight gonna be I think I like it let it stay right here close to you another day thanks for watching I hope you enjoyed what you saw here today be sure to subscribe to my channel and like us on Facebook please somewhere down below here is a link we've got a lot more really cool stuff coming is that right camera guy is there a link down there send me a comment I'll try to get back to you as soon as I can click whatever link click something see you soon
