Congrats on the pipe. Now how about telling us about this tuba? If you think it's "very special" I guarantee the rest of us are curious!

Knowing that you pros goof stuff up on occasion makes me feel even better about the fact that I got a useable leadpipe on my first try (ever!). I posted these in my thread about this little horn, but here they are again:





Did you use any forms or anything to get the shape bloke or was it all simply by hand? I used a block of wood with the corner rounded off to help get the 90° bend (it didn't quite come out to 90, but it works!).

Bloke,

Was your leadpipe pitch filled, or did you use a "Cerebend" product?

Looks great, bloke!

I usually overbend each curve a tiny bit so that when I use draw rings to fix the ovality I made by bending the pipe, the curve bends back just right. (but bloke already knows all this stuff!)

I've always found the fabricating part easy. Wish I could get some tutoring in repairing!

I have better luck with cerrebend, so I'm particularly happy to have no buckles.

I just love that smell of melting pitch out of the pipe... Be sure to warn neighbors, roommates, spouses that the smell and the smoke is completely normal .

Nice pipe, Bloke!
