Thanks guys, just what I wanted to hear not one of poo-pooed the idea of the scrap heap challenge. The budget is small and I'm not going to invest too much money in the build, the most expensive part will be the motors and drivers. I want to use it as a learning curve and then try to help others avoid the pit falls. Wood scraped for tests and trials that don't work will head for the wood burner that does my heating. I've got a feeling it might get a bit warm.

I've been looking at the Solsylva machines and watching vids on youtube of the builds plus reading other forums post along with this one. One thing that I have decided on is it's going to be a bench top machine and the dreaded mdf limited to the cutting bed, as it don't burn that well.
