Actually you can post pictures on forum topics, even if it is a project. You could even do that from a “blog” as well.

Anyway, I was wondering about Y-axis “racking” and if you have noted any at all with your setup?

Here is what I ended up building.

I started out with a Greg Paolini basic design, then designed and added the following upgrades:
  • A Y-axis lifting mechanism
  • Serious Dust Control w/4” attachment
  • Added side mounted adjustable dust baffles
  • Used 1/4in Lexan for router mount for see-though ability—Used this functio to later add a Ridgid 2hp router with self-lighting. Lights shine right thru the plastic and onto work piece

NOTE: I originally had a minor issue with the parallelism of my left right movement. At one end of the 16in capacity I would start out at set elevation and by the end of the movement to the other maximum, I was off by as much as 0.050” in elevation. I basically had to scrap the channels in the MDF until I got my errors down to ~0.005” to 0.010” of error. This then made making long dados (with several 16” spans) possible and easily repeatable. I used a simple digital caliper to measure the size and location of the dado using a 1/4” bit.
