The short/fat Allied one gets smaller that the 45 pipe towards the small end, but - particularly if it's annealed prior to installation - greased drilled dent balls can be pulled (via braided steel cable) through from the large end to the small end, and can re-taper the small end - after the pipe is completely mounted on (supported by) the instrument.

I believe - very roughly - that the 45 pipes might be around .525" at the small end and around .735" at the large end.

Do the 45SLP pipes come pre-bent or straight?

neither.

Have you tried having someone order anything for you made by a Buffet-owned factory?

Nope. They just don't come at all, eh?

Why should I give a crap...AS IF I don't have enough to do...??

smart-@$$ remark:

This is easy to screw up, so I'll end up doing the gig anyway - in addition to repairing the 1st valve casing.

just kidding

I think a Miraphone petruska pipe is similar; I can measure them in a couple weeks and report back. I have access to both pipes. They’re both “smaller.”

Musical instrument repairman in the United States are having to become more like automobile repairman in Cuba.

The shorter Allied leadpipe for large bore tubas is very close to the 45SLP taper and will work well. Yes, it is supposed to be .734 bore but it is thicker walled brass and fits.
