My method is not extreme low cost but it depends on what you wish to do.
I started by buying a used 70's Series 1 cnc Bridgeport for $850, which was in very good shape except electronics. Then bought Larken 3 axis retrofit for $2000.
Now this sounds kinda high compared to you guys, but it's built like a Sherman Tank and will still be here in 100 years. Come to think of it, kinda looks like a tank too. The machine had 3 great high torque steppers and the ways are hand scraped for accuracy. The quick change Erickson 30 taper spindle was a nice bonus as was the variable speed head. The Larken controller gives me a full 3 axis simultanious.
It may not have a big table but it can hog just about anything. With this I can go on to build other machines. Just thought I'd share my machine with you. |
