    Let me know as well. I was looking at hdpe. I have a load of it ready to melt but not sure how I can melt all of it to make a spoilboard 360 370mm.

    HDPE is on the soft side and not good for tapping, so clamping parts down if you use this methods not good to be very good.

    Is trespa waterproof so I can use coolant? Looks hard to find

    It's not 100% waterproof but very low moisture content, the stuff is very expensive and is hard to find.

    I'm no expert on the stuff Jazz uses it for spoil boards that's why I now use it for jigs and an added spoil board to my existing board.

    In uk it's called Tufnol and it's also very expensive. Often used for making Jigs etc because very stable and easily machined. Thou it's dusty stuff to machine covers everything in yellow layer of fine abrasive dust.

    I'm thinking aluminium spoilboard might be best for me when I'm using coolant. I'd consider another tslot bed on top on my current one but it's expensive. I need something I can surface as well.
