Ron, hard to explain if I'm a hobbiest, or a business, or what. I cast parts for a couple of businesses on a regular basis, mostly small investment cast items. If you want to deal with me directly that's fine, but if you would rather go thru a business I can refer you to them and ill still be the one doing the castings. LOL.. My main concern would be the thickness of the parts at the greatest cross section due to wax shrinkage. Dreeves and cheapo have seen my casting set up, its nothing fancy but gets the job done. I'll pm you my phone number and we can chat.
