I cut 4" coasters (about 230 per sheet) out of 1/4" MDF for a local sports plaque maker and with the new vac setup, I've eliminated having to use any tabs. Off the machine into the customers parts bin. Before I setup Gary's vac box, I always had to use tabs which made for a LOT more work. I've been able to lower my price to the plaque shop because my labor has gone down ALOT. He wins and I win.
