That's going to be a very versatile system - can't wait to see it all finished (or almost finished)

Funny you should mention Egg. Used a rotary axis for this Revolutionary Egg just this morning and I am eating the omelet as I type. http://www.cooperman.talktalk.net/DSC00339a.jpg

...it's been finished several times. Actually, I did a few test cuts last night and checked the alignment. I am back in business.

I have one more thing on this project's TO DO list. My old floor had the air intake with filter. I did not like this for two reasons. It did not do the best job of removing smoke near the top of the cabinet. I used to crack the cover open about 1/4" on smoky jobs. I was also worried about my new perforated table. If for some reason the beam went through the work, honeycomb and table and hit the filter I thought there was a chance for a fire. With a couple hundred CFM of air, things could get exciting quickly. The beam is way defocused by that point, but even a 2" diameter spot at 40W on paper could catch fire.

I am moving the air intake to the middle front panel.

This is what I counted

39 for frame
8 for the cover
6 for the table

I would get a few extra. Buy a lot of the cheap basic nuts and a bunch of post assembly nuts. The one's with the spring loaded ball are real handy for mounting the skins. They stay in place in vertical slots.

Here is my new venting system. The flow is directly across the work area so the smoke basically disappears.
.

This should improve things.

I couldn't find details on how thick the alum is. It would definitely be safer. I don't know how easy it is to work with. Do you know the price?
