Milling/Cutting HDPE Poly Deck

Hi all,

I have a piece of HDPE that I need to cut in order to fit it to my frame. Basically all four corners need to be notched and then I need 4 strap holes to hold it to the frame. I also will need to bevel the edges as they are rather sharp. I have never cut this stuff before and hear nightmares about melting, chipping etc. I have a Jig saw, circular saw, router, orbital sander, 4 inch grinder, and a hack saw. Looking for tips, suggestions, do's and don'ts and the like. Thanks in advance for any help!

I built decks for my frame using 5/8" poly. I made the long cut with a circular saw, short cuts and notches with a jig saw. I then used a 1/4" round with a router to round the edges. For the strap slots I started with 1/4' inch holes drilled a little wider than the desired strap width, ran the jig saw between the holes, then ran the router down the slot to round the edges. I am very pleased with how they turned out and found the material remarkably easy to work with. Good luck

Yup, treat it just like wood. No nightmares necessary.

The resulting snow storm is a little messy, so work where it won't get into everything you own AND you can sweep it up easily.
