Adapt the vacum cleaner port of the Makita PJ7000J Lamello/Biscuit Joiner to accept 36mm OD hoses of Kärcher and the Festool shop vacuum cleaners. (Careful. Festool has 27, 36 and 50mm tubes.) Both sides are slightly tappered for a tight fit. ##This design has been tested and it works perfectly## The .AD_PRT file is the original design document made in Alibre Design / Geomagic Design. It is parametric can can be changed to fit the other Festool sizes. I won't create them because I have no such hoses to test that they actually fit.
