Yes is the answer to sdb's question. A basic pressure pot is at least $125, a 1/2 gallon of alumalite is gonna run you around $60 and the you either need to make your molds or buy them. Google 'Cactus Juice' and find the site for Turn Tex which is where Curtis Seebeck has his stuff, including cactus juice for stabilizing wood, and he also sells pen blanks, and I think knife scales. You can mold just about anything in the Alumalite, it's just a matter of preparing the stuff properly and getting in the molds correctly. It's pretty great once you get going, and a pine cone would be easy in my opinion--I've actually done some 'mini' ones, and they made a great pen blank.
