Electric carving knife to start with, then an orbital sander

hey what grade paper? grab a selection of course , medium and fine Shelpi and have a test on the foam. Have found over the years a fair bit of variance. ;)

I may not agree with what you have to say, but I'll defend to the death your right to say it.

Can I ask where to get good firm foam from ?
Clarke rubber perhaps ?

I use an electric bread knife to first get the foam into the shape I want. Then I use my belt sander with #60 Grade belt to carefully finish off the foam. Then I stretch and glue a thin polyester material over the foam using spray contact adhesive. I learnt this method from an upholsterer years ago.
I've never been able to find dense enough foam at clarke rubber. I'd be interested to know what clarke store stocks high density foam...
Arrogance.....A way of life for the those that having nothing further to learn.

I give it to an automotive trimmer. It's so easy.
