Not mine, and not my design... other than the ubolt for a shackle on the router, this looks pretty good for the price.

If it were my design, or redesign, I would replace the ubolt with a plate and i went away from unsupported linear shafting rails... so it would have a light frome (3/8" or so) and open bearings to keep chatter out.. and brakes on X and Y to lock for passes..

on serious review of the pics, this DOES have "bounce" in it, evident by some gouging... would work very well... or he price, it looks like it would work.. the single bearing per side is offset wiht the "Shackle" on the rail

I wonder if that would hold to tolarances for a good stock.

For a few dollars move I would sell my original machine with several patterns.
