I decided to post my build log to this site, it's still in process but near completion and I wanted to share my progress. I'll be uploading in sections tonight.
I have a very restricted workshop and limited tools, so this has been a bit of a challenge to put together. A wobbly drill press, a Dremel and a carbide tipped blade on my miter saw.
I started off by doing a lot of reading on CNCZone and other places to decide on what I wanted for a machine.
I decided to go with an 8020 build as it seemed like it would be fast to fabricate and build, but after pricing the 8020 out and coming up around $1600 with some parts still missing from the price list I realized I'd need to look into some other options. I ended up going with used Bosch/Rexroth extrusions from eBay and also ordered some parts from Bosch directly.
In the attached two photos you'll see my original designs and the 8020 price list, my how things change over time. The end product looks not too much like either of my original concepts below, one which was a moving table design.
