Hi Chris,.....nice machining as usual!
This is not the only way to make a barrel,...when I made my first one in 2010 it was at the height of 'brass madness' and I was quoted £97 for a half metre of 2inch tube!?!!
I thus was forced to 'roll my own' by annealing 1/8 brass sheet then forming around a piece of scafold pipe using the wooden jaws of B&D 'Workmate'.......then squeezing to roundness using crab clamp which brought accuracy (roundness) to 0.5mm...and then finally, finishing on the Chinese mini-lathe which lives in my conservatory.......So, this brings together many of your recent stuff like cost of materials and far east machine tools etc!......keep up the good work!
Wow Bob, that's a seriously creative solution! Brass prices are totally out of control aren't they - I'm not looking forward to my next order!
......The silver soldering is tricky but when you get it right it results in an invisible seam once polished. Actually, I have become very interested in the earliest clock-making methods and thats how the old time makers like Tompion etc made tubes and barrels
Thank you for sharing, I didn't know that. I am also very interested in the traditional clockmaking methods. There is so much practical good sense in the way they did things, some of the 18th century texts are an absolute goldmine of techniques and ideas. They just had to figure out how to do almost everything themselves... many thanks Bob!
Fabulous watching you work. Is that a new lathe?
I've had that one for a few years now - it's an old 9x20 that I picked up along with a bunch of other tooling from a retired clockmaker who lives nearby. It's come in very handy for when I need the extra swing like in this case. Although I find I prefer the little red lathe for most everything else - just love the variable speed :)
