I have a new motor coming for my disc/belt sander I feel like I'm working one handed without it. Between that and the plasma cutter I can make a lot of sparks! I have been using the drill press alot beyond it's capability but if you cut two pieces at a time by tacking them both to a plate or doing two ends at once I can swing a 4" holesaw for the fishmouths etc. A 14" chopsaw works well also if you do two cuts about 17 degrees to the centre of a tube it makes a nice fishmouth that needs minor or no grinding depending on weld method. I like the Pferd brand of grinding and cut off wheels, they seem to remove quite a bit of stock without vanishing themselves. Good thread! Know where the extinguisher is and keep looking up if you're working by yourself. It's a good excuse for a sip of something anyway
