Cast a wheel for the BX's mower. It weights in at about 4 times what my previous largest cast was.
This was a test to see what could and would go wrong. A lot did but then I was trying a few new things. I am pleased that the results are as good as they are.
Started with a wood pattern. It is butt ugly but could be used if cleaned up. Thinking most of the holes seen in the first image is due to shrinkage. Not surprising given how massive this thing is. Would like to do a version with spokes.
To create the axle hole the head was cut off a 5/8th inch bolt. The cut end was rounded and polished. The bolt was coated with soot from a candle. The threaded end was embedded in the sand above the pattern. When the pattern was removed the bolt remained. After casting the bolt was pressed out of the wheel.
I have an image of the bolt that will be added later.
The top of my casting seem to come out smoother than then bottoms don't know why. Maybe the folk on alloyAvenue know.
They say it there is porosity it will show in the gates. Looks good.
