The Inside Diameter of the Tenere damper tube is 18mm. If you chase up a meter of 20mm diameter aluminium rod and have someone turn a 1.5 degree taper in a lathe. Start the taper at 16mm...should work out fine..

Then simply a matter of drilling a hole through the other end to make a T.

Doing something similar with a broom handle also works, providing the the taper is even.
