I was fortunate to have an email exchange with Melterskelter and he told me about this great resource. I have a small foundry, beer keg size, that I have been using for aluminum casting and I really want to get into doing cast iron. As a hobby I refurbish old machines and have a number of pieces I would like to fabricate. I saw the pictures of melterskelters camelback straight edges and decided it is time to start learning about cast iron work so here I am looking forward to reading up on as many threads as I can. JB
