Tell me about these kit cutters:
Ask the hard question first of these folks.
How large of sheet can you cut.
How thick of plywood can you cut?
How long wil it take?
One of the guys listed can only cut up to 20 inch long sheets with his home equipment, but will send it out for double the cost.
Another guy listed takes about 5-7 months per project.
I don't use any of the noted, because of such. For your large sized project, you need a large sized cutter. Ask them yet another hard question, "How much does your machine cost?" If it is about $10-15,000, it is a small machine. If they say $50,000 to 1/4 million, it is a large machine, and that is where you want to go.
