wow, machining a square hole that size is not something i would want to do. great job on that!
as for knurling there’s a lot of tutorials on youtube. to sum it up the part needs to be a specific diameter depending on the pitch of the knurls.

I recommend it! For shop work, or just lounging… These will be all the rage, mark my words.

Thanks Ross! Methuen is a bit of a hike but it sounds interesting… I haven’t fired up my Makerbot in a while, might be a good chance to get it running again.

Hi!
I came here via Hackaday, but then your pic of narragansett made me wonder where you were from.
We are having a boston reprap user group meeting in about a month and I figured you might be interested. You seem to be a bird-of-a-feather. Here’s more info if you are interested.

Yes, good call… I originally wanted to have a sealed enclosure for dust ingress reasons, and iterated through several designs with aluminum ribs, etc. to transfer heat out of the box. I was worried about it not being enough, so in the end I added an 80mm case fan in the bottom of the enclosure, and a bunch of holes out the back, toward the top: http://www.flickr.com/photos/jmillerid/6073043565/in/photostream

Have you considered dropping a fan or fans into the PC/Display enclosure? I’d be concerned about overheating with the processor, power supply, display and hard drive (HD to much much lesser extent) all in the same enclosure. Some forced convection might be just what the doctor ordered…

It’s a good question. Here’s some good info on plywood grades: http://www.plumcreek.com/Portals/0/downloads/productInfo/V995.pdf

For reference, here’s the quick cost comparison I did on 3/4″ plywood grades (4×8′ sheets, available at Lowes, as of 6 months or so ago):
“Pine Rtd Sheathing” (I believe this is CDX) – $19.97
“BC Pine ULX Exterior” (this is what I bought) – $28.97
“Arauco Plywood ACX” – $37.02
“Oak Hardwood Plywood” – $44.97
“Maple/Birch B/B Plywood” – $47.98
MDF (for comparison) – $29.98

Ah, stupid me: I shoulda just Googled in the first place. A = grade of one side (good); C = grade of the other side (meh, but not D).
