man you have almost convinced me to take up casting. if i could squeeze 30 more seconds in a day i would make time to do it. It looks like your retaining wall really helps with your work. would you recommend having a stone table or something to replace the retaining wall. sort of a casting work bench?
excluding the 3d printing and mould making, from the moment you decided to make the pour, how long did it take? i mean the actual pour. from getting your already made moulds together, putting on your gear, so on so on. is one pour basically a day project or can you knock it out in a few hours?
