Progress is slow here.
The current task is still the tapered column tapering 300mm by 100mm. It is coming along (as in the earlier photos).
The main chore after hammering it for an hour or two is annealing the big copper section, that requires a 30 min drive to a mates workshop to use his Oxy set.I emptied the gas last time I was there (not a good look) :angry-banghead:
It is a heavy job to hold and hit with the hammer at the same time. The other slow down is it is a very noisy job that can only be done when the neighbours are not at home. One of the family said they could hear me banging the crap out of it 4 houses away! Nice :violence-smack:
I have flared out the first 50mm of the bottom end like a trumpet bell now, ready to meet the domed boiler lid (the top of the boiler is 520mm across). The remain job to making all the small dents into one smooth surface and it is a bitch of a job because of the way I stitch the copper together (one thing I would do differently next time)
I am cheating on the lid of the boiler and using a 2nd-hand round copper sink. I could cry just thinking about cutting a 300mm hole in it to fit the flared column.
There are some bloody good people on here I must say. A piece of 6" copper pipe for the man-way inspection hatch arrived in the postal a month or so back from a very very kind AD'er. Thank you to you again, SIR :handgestures-thumbupleft: Now I am working on the lid and seal for that now too. By the time I cut the 300mm centre out of the copper lid/sink and then the hole for the 6" inspection port there will bugger all left of the bloody beautiful copper sink. So best I don't cock that one up
