I'd like to find a tools seller in Europe where I can get various conical hand-reamers 1:20 to be used for small & large bore trombone receivers and possibly American/European tuba receivers. I know the German company Boehm, but there one of the larger reamers costs a fortune. I suspect I could get a much better price at an internet selling machine tools shop, but have hard times to find 1:20 reamers (Morse and 1:50 is easy). Maybe I may tap at the knowledge of this fine forum to locate a seller?

Yes, that is the one I know about - and tool 106 - the tuba reamer . is 179,00 Euro plus shipment -

Since an american tuba shank is almost 1:20 in taper, and has the measurements - left inch, right mm
Code: Select all
Shank Receiver Bottom Conus 1:xx Shank Receiver Bottom
1.1250 0.575 0.519 20.089 28.58 14.61 13.18
I thought I could find a cheaper standard 1:20 reamer to do the job ??
For example a Jarno taper #5 ??
Code: Select all
Large end Small end Length
#5 0.625 0.500 2.500
Do anybody know a place to order these cheaper than the specialized Boehm tools ??

I found these - but they are too small in diameter
