Sounds like you are progressing nicely Greg. I'm really looking forward to seeing this thing fly!

I'm with ya Greg, my problem is you can't use a larger wrench or bigger hammer to bring them into submission.

Nice looking machine, love the racks. I cheated and bought ones from McMaster. :)

I used rack and pinions, on my 4' x 4' router. Heavy design for cutting wood & aluminum. wrustle will love my 25,000 rpm spindle! Yes, need flood coolant to avoid melting 1" aluminum plate. :)

Video was first run (little tweaking was needed)

First recommended addition.. ESTOP!

After posting a video like that Tom - we all expect a build thread now...

No.....we want to see a "chip making" video!

roundrocktom, Thanks for the "in action" video.
Don't ya just love those aluminum extrusion structural? I don't mean paying for them, just using them.

Good video, thanks. Do you use a router bit or a milling cutter on aluminum.

Thanks for the video Tom

For speed and rigidity, solid carbide end mill. In the video that is a Melin drill mill. 1/4" 90 degree tip, so can peck drill nicely for 1/4" holes. Cutter will drop 0.176" into the backer board (1/4" bit). Catch is to remembering that when you design in 0.125" tabs (oops).

Greg -- your machine looks nice and rigid, so you have some other options other than plasma cutting!

Local metal scrap yard had a bunch of those extrusions... 8' long, with dented ends. So they were scrapped.
