The needle at work

This is a Bidoz tube with inner tube mounted on a Würm needle, which is a perfect match. But notice that the bass bottle can move on the plastic inner tube. This can be avoided with a small drop of super glue between the inner tube and the bottle. Notice also that I mount the needle with the taper close to the vise to avoid any wiggling.
