Hi everyone. I am new to this forum and would like some help please. I have an old Bosch PHO 2-82 planer and would like some advice on the best way to connect my workshop vac. The problem is that the waste vent on the planer helpfully is a roughly 6cm x 4cm parallelogram! I have tried duct-taping it to the vac but hopeless. Any suggestions how to make an adaptor or where to buy one please?
