DIY CNC in new Woodsmith

Just got the new Woodsmith magazine and it had the first of a two-part article on building your own CNC. Only skimmed it so far, but it looks as if the bed and frame are made out of plywood, with the bed made as a torsion box. Second part will cover building the working parts.

Interesting, the guide rails for the Y axis are made from plywood and they are guiding metal V bearings. I wonder how long it will be before the rails fail!

The plans call for the plywood rails to be capped on both edges with aluminum angle to provide a long-wearing surface for the V-bearings. I don't think I would build one, but with an estimated cost of $1,300 for all materials and parts (not including the cost of software), it might be a way for someone to get into CNC work. The 24" x 48" bed area is also an attractive feature.

Tom , I can’t find the article, but
this is a Joes cnc , and to keep costs down Joe uses metal angle iron for the V bearings to ride on.
The V bearing also need to be continually adjusted as the angle iron wears. I was going to build this version myself,as to me it’s the best bang for the buck , but I’m really wanting use linear bearings now .
At 10:30 you can see how the carriage works on the rails

Woodsmith CNC router

Hi all,
I am almost complete on the Woodsmith CNC router build. See my blog in Lumberjocks for details.

I can assure you the rails are very robust and I am convinced they will last a long time. It's a great build but room for improvement. The pics below are quite old, I'll get some new ones up.
Feel free to contact me if anyone wants to discuss the build.
