That is undoubtedly the best use of an inverted ironing board that I have ever seen. Couple of tips- as BobR2 said ground the system. There is no doubt that cutting and grinding create static electricity. I have been building cabinetry and furnishings for the aerospace industry for 20 years, and we use shop collector systems that use galvanized tubing with diameters of 4'' up to 20", and everything is grounded. People underestimate the hazards of prolonged dust and /or fume exposure. Polyamine resins, isocyanates, carbon fiber and glass shards are just a few of the things you DON'T want to breathe, and we modelers work with them all the time. The dust from many hardwoods are classed as toxins by OSHA. Go to their website for more dust collection info. Finally, the vacuum cleaner hose may be handy for odd turns, but the spiral wire wrap design slows down the airspeed in the hose- and creates noise. Don't believe me? Connect two or more vacuum hoses together and turn on the system- it will absolutely HOWL! Use hard pipe wherever you can. Dust free is the goal, but less dusty is the reality. Good luck!
