Well... that didn’t quite work how I hoped! Having finished my plywood former and cut the stainless steel for the top layer the ply and steel started to ‘slump’ at the edges of the ‘cut-out’ under the pressure of the press! I quickly remedied this by lifting the steel sheet off the plywood and placing an acrylic sheet between them. The results were instantly much better with a clean and even line around the form. My feeling is that the tolerances are too little for the size of the mould and the depth of the form I was trying to achieve. I can’t deny that I am a little disappointed as I was trying to give up using acrylic in my mould making altogether but if I stick with using plywood for the depth of the mould and then have one layer of acrylic under the top sheet of steel then at least I have greatly reduced the quantity of acrylic I use. I’m not going to give up here though I will still keep looking for an eco-friendly alternative. I’m wondering if a slightly thicker sheet of steel would be better or if I could use a bio-plastic alternative? If you have any recommendations that you think I could try please let me know. This all proves that there is still so much to learn! Considering all the problems I have had I am very happy with my first test pressing from this mould. I’ve made some minor changes and hopefully with the second test it will be good to go! I will share the results with you all soon.
