    any pics of the gauge? I cant think of anywhere around a furnace that a vacuum gauge would be unless someone had used it for some sort of early vacuum casting maybe. I hightly doubt that, but I dont...

    Im not sure how true this is, but Ive always been told that when it starts melting the end off of a piece of rebar or steel bar when stirring/poking the melt, it's at pouring temp.

    yea, it looks like he's been at it much longer than that, good gating techniques, pattern making, and surface finish.

    Anyone recognize this guy? It looks like he just started recording his videos on youtube of casting, but he looks like he's been doing this for quite a while. Im just curious if he's one of us?

    it looked like he poured the metal a little too hot, the sand will do that when it's poured too hot, that or just some minor sand wash, but due to the texture, it looks too hot.

    looks like a decent start, Ive seen some people using cheap lipstick for finding high spots when scraping when they couldnt get the prussian blue. I just ordered mine off of amazon tho.

    looks pretty cool, that would be handy for a filament extruder more than the burnout furnace. I usually just stick my plaster mold in a bonfire overnight and pour first thing in the morning.

    The spindle bore in mine isnt a bad size, it can hold up to 1 1/8" stuff, but it is a 9" lathe, so I think it's sized accordingly. For most of the stuff you really do, your not going to have a 6"...

    looks good, I cant wait to see it running! I was curious how you did up the bearings in the wheels, if you went with embedded bronze bushings in the aluminum blocks or how you did that up?
