One in my shop, I have done close to 1,000,000 with it. Had to replace one heater (easy) and one controller (also easy) over the years. I make for myself and friends. Most casted in one day 6000, all were lubed same day but with 2 of us at it. I usually do about 1000 a day after that the right hand stops operating the press but the left hand keeps lifting the beer.
I have 1500 lbs of ingots ready to start this fall. I make 45, 38, 9mm and 40. All molds are from Magma. Make sure you get their mold release.
I also have the feed through sizer from them and make my own lube. 60% pure bees wax, 20% paraffin 20% Do All (has a mixture of lubricants in it including carnuba wax) and red candle wax dye. I have made my own three foot long mold for the wax and slice it in pieces correct length for sizer.
