BJ - I saw a plan for making the sander like you mentioned recently but, wow, it looked complicated - other problem I have is very limited space, with emphasis on very (maybe I should just get rid of a car!) - but appreciate the suggestion and will look at that again.
Doug - What you're describing sounds like the kind of thing I was thinking of - seemed pretty simple - maybe I'll just play around with that idea a bit and see what materializes - I KNOW I saw a jig plan somewhere - with all the links I've got, you'd think I could hit it - curved sled sounds interesting too!
