It is more work than just poring sand and resin on the back but it really pays off in ease of moving and storing.
I have fuse molds done this way that are 15 years old and the seams are still tight and and aligned. Only my molds that do not have the end grain on the flange have wandered, such as my DLG Pod molds and a couple of early TD
Yes Dave, you had lost me for a while there. However, the above description is very persuasive! I really like the "twist the entire mould" and "they just pop out" part!
Got me thinking and re-thinking!
