: Does anyone have suggestions for tools to use shaping a foam seat?
: I've started using an angle grinder with 50 grit disc,but I can see it will
: get tough to control as I get deeper.
: Can anyone post a pic or description of sharkskin?

: To indicate when I've got down to 1/2" I plan to put 2 saw cuts on the
: bottom of the seat from the back to the middle. I hope this will work?
: should also provide drainage.

Here is an interesting way I carved two seats.
Take a 12 inch piece of metal strapping ( the kind used to strap wooden crates). Then bend it over on itself and tape the two ends together. You are then left with a rounded section on one end and a taped section on the other. Next, take a blow torch and heat up the rounded section. As soon as it is hot, try scraping your foam block with it. It will cut like butter. Keep heating and cutting until you have a good shape. Then finish with sand paper. Good luck - steve
