I am looking to buy, or make, an inexpensive extruder. Any ideas?

I've often thought that you could make an extruder out of a decent quality
caulking gun. Not the $1.99 jobs at the cheapo hardware store, but the
professional types that are made of much heavier stuff.

It ought to be cheap to do. The limitation, obviously, would be that you'd
only be able to extrude fairly small shape and your reservoir of clay would
also be pretty small.

But it might be worth a shot.
