hmm carbon hss cheap dear i dont know il see what my pocket can afford when i come to buying a new one

hi alan il bear that in mind and when i get the money as i have to buy a new one i will buy hss

ah ok so the strip goes on the inside i imagined it going externally il look in to the solder and when i can il make an order as for the staying well i will go for the best method, iv been looking in to the copper for the back head it calls for 13g would 2mm be ok as the fittings wont be screwed straight in i will be making bushes 2mm is .337 smaller then 13g i can get a small peice big anougth to make he back head as i dont have the money or the need to buy a big 300x300 sheet

many thanks mike

hi to you both yeah it was the tich just a rod, i was going back and forth hardly any movement but it grabbed on the wind out. and if i was to scrap it (i was seriously considering it) i would of had to remake a few parts and fourtunly then it was a carbon steel tap im glad i got it out so is the wife because im very inpatient normally but last night must off been a good day

many thanks to you both for your replys

just broke a 7ba tap in a 3/16'' piece of stainless steel tried knocking it round nope dried knocking it thru nope in the end i heated it to bright cheery red and broke it out with a carbide scriber then drilled the rest out, result nackerd tap nackerd scriber but saved work piece,

so my question is would the heating of it to such a heat

a) changed the structure of the tap and made it more brittle as before the heat it wouldnt break up.

b) i was just really paitant and as the scriber was harder then most things that would fit in to the hole it finally gave in

don't laugh to much my pride is failing me

hi all again the barrel is nearly done just a couple more bending sesions then we should be there as mw said the next thing is the long join down the boiler tube, im guessing that a strip of copper the same as the boiler is used and rivited in a zig zag patten alternating side to side. will 1/16 copper rivets be ok to do this and how wide should the strap ideally be?

many thanks once again mike
