Todays Project - What did you do today?

I bought the cheapest cutting board I could find which was most likely HDPE. I drilled it with a fairly slow spindle speed and high feed rate. I got curly chips wrapped around the bit but the hole was clean and no melting. Same when I ran a two flute endmill over the cut parts to square them up. Turning this stuff on a lathe might be a pain but for this application the material was easy enough to work with for sure. I plan to make a few more to hold my 5C collets. I just need to find a few larger cutting boards.

Edit: I did try to cut the holes initially with a 7/8th spiral drill bit after making a pilot hole but that just wasn't going to work, the 7/8th spade bit worked slick though. The holes were chamfered with a cheap de-burring bit like this one.
