Very nice.

Since joining this forum, I've been of sort of a tool collecting binge. I have a bunch of older, different brands and some of you have seen my Proto display board, and even are helping fill it, thanks!!

I love it, and would like to see the Proto one!

The only issue I see with the foam on the top layer is labeling. I've messed around attempting to CNC socket / wrench sizes into the Kaizen foam and it doesn't work so I've always just used either a paint pen or silver sharpie. Nice thing about the HDPE is that it's fairly easy to engrave the size labels although, I am having issues getting the feed/speed right for a 1/32 tip router bit. I keep getting the "melted" bits hanging on to the cut but I'm afraid to speed up such a small bit for fear of breaking it. If anyone can offer insight to this I'm using a 1/32 tapered ball nose with a 5% taper to engrave the size labels .88" into the plastic (to reveal the center color for contrast) but continuously get the "hairy hang-on" ****. Any feed/speed suggestions? As far as I can tell, they don't sell a regular up-cut bit in 1/32 for plastic.

Not sure if any answered this but.. I found when milling plastic if I supply air blowing at the bit, where its cutting, it keeps the "hairy hang-on" **** to a min. now to keep reading.

Yeah I'd take one too if you'd ship to Canada?

I have a huge dust collection system hooked to the setup which I thought would serve this same purpose but it really doesn't.

industrialcnc.com China made but honestly, it has worked / held up very well.

+ me too. Just stumbled onto this thread and want one also.

I can't guarantee a turn-around time but PM me.

Super late to the party, but could you cut a pocket in the main color to make engraving into the contrasting color easier? Like have a 0.5" radius around the lettering to make your depth cut not take a big bite on your 1/32" bit?

The only issue I could see is if dirt, grease, gunk got in there it wouldn't be easy to clean, but a little bit of clear epoxy could help that.

Have you tried a veining bit for engraving? I use one to engrave arrows so assembly know which direction to attach hangers on particle board. Here's a link. Not the same one I use. I will drop you a pm when I go back to work Monday when I find out the exact bit I use.

Here's the machine I run.
