I had pretty good luck using a small disk type pad on the cordless drill. This pad is about 2-1/2" diameter, and is like a flap sander with a disk behind it. I used the coarsest grit I could get, which I think is 40. Final shaping with a surform. Minicell is kind of tough, in that it's rubbery texture is a little hard to grind. Once you get the feel, it goes pretty quick. Of course, I didnt do as fancy a seat as Joes. I intend to take a closer look at that next month...

: Hi Lee;

: I can't help you on that one, but I was hoping you could perhaps help me.
: I'll be carving my minicell soon, and I'm looking for the best carving
: tool(s) to use as well. I'm not familiar with the zig-zag japanese rasps,
: could you elaborate on exactly what they are? Actually, I'd like to hear
: how you carve in general. I'm a bit afraid of going right at the foam with
: a fast removal sander as some use - I'd rather do it slowly and waste some
: time as opposed to esthetics . . . My plan is to build a seat assembly ala
: Joe Greenley, and only time, and tool selection/control will tell how that
: turns out . . .

: Thanks in advance, Spidey
