While searching the Internet for computer-controlled tools, I found out that there is a new machine called CarveWright. I'm thinking of buying the machine to create model cars and other projects. One problem: $2000 plus shipping and sales tax for the machine. Other machines like ShopBot cost more money. I have some arthritis and cerebral palsy. I'm not sure if there are cheaper machines. I have Wishblade personal media cutter. My computers are on the second floor of my house and my workshop is in the garage below the first floor of my house. I can't go up and down the stairs well.
