    Vibrating concrete in small casting

    making plaster moulds I found that adding a surfactant significantly helps with air bubbles. I tried several different flavors of dish soap. Ajax lemon flavor was by far the best! Anything with an oxyclean prevents hardening.

    Laser welding update!

    Definitely showing discolored on the id. But not burn thru. I haven’t been very involved. Think they are running around 450W with a revolution time of around 15s. With a second pass without the wire feed on.

    I have (had) a little one, smaller than a hocky puck. Had a suction cup kind of back. Push a button and it had a little pump in it to **** down the cup. Great for hanging things. Think i got it as a Christmas stocking stuffer.

    Concrete release agent

    Can’t see anything. Not sure about concrete. But when casting plaster moulds i add a very small amount of Ajax lemon dish soap as a surfactant and viberate with a palm sander. For some unknown reason only the Ajax works and actually cures faster. Others inhibit the curing.
