I always think of my father when I see Myfordboy find other uses for common items that most people would discard as trash, e.g., cutting a plastic milk bottle to make a funnel. My father grew up poor during the Great Depression and never let anything go to waste. He always insisted, "I'm not cheap, I'm frugal. There's a big difference."

@sumorabbit21603 жыл бұрын
@@tommothedog It's my understanding that green sand uses water as a binder, unlike Petrobond which uses oil. I've seen a few people poking small vent holes into green sand to vent any steam pockets, but this seems to be done on larger castings. I'm sure the more I get into casting I'm going to run into these issues, but one bridge at a time lol. myfordboy did a video awhile back which included sand prep and core making, if you've not seen it it's well worth a watch kzbin.info/www/bejne/omTSoZ6wdtuJh80

Looks like the casting turned out well. I had wondered when you just dompted greensand on the mold and how good it went between the fins. Surprised the 3D software did not allow you to put the text in the print. Extruded text can be done in Fusion 360 as I have done it. Every time I see a casting video makes me wish I had the setup to do it but at 73 think it is too late to start.

I have to wonder.. Why not make a extruded aluminum frame. Something that either the flask sits on firmly, or the frame attaches directly to the flask. Put some guide rails on it with a gantry as well. To the gantry attach a base of sorts. This base can by rather thin and hook directly to the lifting screws on the pattern, and since it's constrained by linear rails, you can lift the pattern straight up out of the sand. So "fewer" worries about the hand shifting a tad and knocking over a fine detail? I dunno
