Looking good. My only concern would be the wear on the aluminum angles but you've already acknowledged that will be "wear" parts and need to be replaced. Also, I didn't see any mention of bearings for the lead screws.

The bearing setup shown above is only because it makes the whole thing a lot easier to plan and assemble. However, I'm currently testing the same bearings+angle method used on your machine and a lot of other CNCs. It's an extremely popular method but I'm searching for the easiest, most cost-effective way of doing it. My aluminium angle is only 1/2" so I would need to buy yet another 8' length only for the bearing supports. It's not exactly cheap and I would only use a small fraction of it. Using square tubing would make assembly easier, but I also don't have that.
I do have six smaller bearings that fit my 1/4 threaded rods. I can't remember where I got them, but they were in my box of parts that I've accumulated for the last five years with the goal of building this CNC.
What trimmer or router are you using on your machine?

THIS ONE It's a little bigger than most people use on these home made CNC machines but another builder of the "book machine" did it and was happy with the results so I bought one too. I upgraded the collet system on the router though to these precision ones. Which allowed me to hold smaller bits which was essential for the mini coin doors. THIS is where I purchased my carbide end mills by the way. Prices are amazing, product is awesome. Only downfall is the $75 minimum order. Unfortunately or fortunately depending on how you look at it, it's pretty easy to meet the minimum with carbide even at their low prices.

Hitachi M12VC, 3.3 kilograms... it's quite heavy, I hope your machine isn't flexing in the middle? ???
From what I've read, most people seem to be happy with the Bosch Colt, which only weight 1.5 kilograms. Then again, from what I've read, the M12VC is also the quietest router in that price range.

I just got a Hitachi M12VC from my parents! The cost of this project just got a lot lower! :applaud:
Thank you both!
This thing is really quiet at 8000 RPMs! :o
