Hi Dwg - I'd be careful starting a business to make money and buying that type of machinery to do do it. You end up being a poor machinist vs a product designer and seller. Once you have this machinery its difficult to place a commercial value on the parts as your time and machine payback is a rubbery value. You are subsidising the machine and the work. If you can't subcontract the parts to proper machine shops that will make parts 10x faster then you can then how do you scale up? So find better machine shops and when you get quotes find out the cost of 10 units or 100 units to see what scaling up does for you. It's your call but I've been there done that and unless its thought out you don't win. Peter
