    molten metal temp

    I must admit I don't use mine as often as I probably should. I tend to rely on the 'poor man's pyrometer' - dip a preheated steel rod in the melt then see how much (if any) sticks to it, to judge whether pouring temperature has been reached, as well as other clues like what colour of hot it's...

    molten metal temp

    I'm a year late to this party, but I really like mine, built mine similar to Henry Davis AKA HT1 metalworks', using a MIFCO replacement thermocouple tip that needs no protective sheath. I know some guys on the home foundry forums forums who instead buy cheaper probes then make or buy graphite...

    Ammco 6" Metal shaper

    Nice! I do all my sand molding and casting out of my 12x16 detached shed, I can get a lot done in there but space to lay down more than a few molds at a time is the main bottleneck. Looking forward to seeing the casting! Jeff

    Giant metal boulder sculpture (art casting with sand molds)

    Pic of the boulder sculpture looking closer to finished, David has been busy. Though the lighting doesn't make it easy to distinguish the metal pieces from the stone... Here's a profile on the artist, that's me in the background working on an experimental tree bark mold while he was being...

    Casting sand

    Nice setup. I have some casting videos up on YouTube also. FYI Tim Smelko retired since you bought your sand, so the Smelko Foundry Products in Milton you knew is now called Foundry Supply Source, and they've also moved to a new address. Still in Milton though. I have an email from almost...

    Cast Bronze Plaques

    12 of the same plaque, or 12 different 100 word plaques? That's a lot of pattern letters... Jeff

    Casting sand

    I really meant to come.back to this thread sooner! Sorry. I hope late is better than never... Do you think you might have the organoclay binder that can be used to make oil bonded sand? If so that is something I've been hunting for, for a few years. Nobody wants to sell me less than a...

    Casting sand

    I've worked with greensand, petrobond, and lost foam casting. The insulation foam panels (blue/pink) is easiest to carve/machine since you don't end up pulling out the little foam beads by accident, and theres no bead texture on the surface of the patterns. Kelly Coffield on YouTube has some...

    Aluminum bronze bolting plates

    A new client in Montreal needs 2 of these to attach and support a bed frame to a strut trolley for a pulley-bed system. They are working with a CAD guy and sent me the 3d model to look at, so that I could let them know what needs to be changed to turn their model into a usable foundry...
