    JST,

    I just relooked at the video. Now I see what you are seeing---plywood sheeting laid on the ground to make my pouring trolley run more smoothly. My humblest apologies for not realizing what...

    Whoa! Water injected UNDER the melt—-the worst possible situation. As they say “you can put water on (molten) iron, but you can’t put (molten) iron on water”—-trouble in the making. I’ll have to...

    I have not personally witnessed concrete popping due to hot metal spills. That said I have had little opportunity to do so as I have never really worked in any foundry except my own and all my...

    Yes, I spent quite a bit of time trying to come up with a foundry setup that would allow me to safely work solo.I actually love working with folks but hate relying on them.

    No, that guy in the video was me! I can see why you might have mistaken me for him. ;-) ;-) ;-)

    Truth be told I did not know who Joe was. Google came to my rescue.

    I don’t always let them cool completely to room temp. Letting them get down to 250 is well past cool enough. They will be in that range 4 or 5 hours after pouring. If I leave them for 12 or 15...

    Here is a video of the first 26 pour. I left it long on the end so you could watch the coal gas that evolves from the mold catch fire and slowly char the flasks. Subsequent to this pour I applied...
  11. New Design 26" Prism/Straight Edge/Parallel/ Level is ready to go!

    About two months ago I started talking about making a new straight edge/prism of about 24" length. One of many good suggestions I got here was to make it just a little longer---26" That seemed...
