The last core box for my uniflow , just speeding up the setting of the casting resin in front of the fire.
The wood is I think Rimu, from inside the wall on my daughters 100 year old house. They have done some renovations, so I slipped in and grabbed all the old wood. Waste not want not.
Can't show the finished pattern completly but here is one of Claire's plan pots, wood, ideal molding box, even has handles. Dangerously close to a cast.
Deeply impressive (and fast) work!. We need to build a cloning machine . . .
Sounds distracting. We'd spend all our time trying to collect Elle McPherson DNA samples .
Don't you look at my accountant.
He's the only one I've got.
Our old mate, the Oil Burner, would say don't be a Sissy and be worrying about lining it! Build it and run it and if/when you burn the bum out of it , grab another old gas bottle and build a better one.
If you're concerned about thermal efficiency, wrap it in Rockwool(R) or whatever you can find handy.🐑
Satisfaction through immediate Action.
Nice crucible, by the way! .
Cheers, Daryl.
Yes that's what it is ( but looks like a gas bottle) - anyway, having built one before I don't think it matters what you use for a case - the most important part is the hot/hard face part in the middle and the rest can be surrounded by whatever provides insulation! - however I did use two layers of rockwool before (and it was very good too) but as I moved it from place to place in the car, it compacted and the inner started to move around a bit! - so maybe I'll try pumice and/or perlite, which will (only just) be held together by cement of some sort (to keep everything in place), but perhaps I'll still use a thin layer of rockwool between it and the hot face. Maybe try using some of our good old Auckland Scoria as well - this is quite lightweight and rigid and will help support the Perlite (lightweight, very crumbly, but a good insulator).
BTW I think Neil has moved way past the simple bargain basement "rockwool only" furnace now!
But, as you suggest. nothing's really as critical as some people would have you believe it is!
I do still want to build something which can be used over and over and hopefully see me out! (don't have the energy to keep on building them anymore).
Trying to build a burner at the moment, (but, with lots of family matters and junk clearing to be done in my garage - all needing my attention as well, then ...........who knows!).
Strokers Galore!
The pot plant molding box. Dividers are so the outside sand segments are made and removed in thirds, once they are molded / gassed, the segments can be moved out of the way, pattern removed then returned to position with cores in place. Still need a top and bottom mold box. Perhaps next weekend.
Almost getting a little excited to see the aluminium result. I've got a number of cylinders to pour at the same time ( seeing as I'll have a pot full of LM13 ) so it might be a while before I actually melt aluminium.
All ready for sand.
Cases will have to change, rotary valve will go on the opposite side now. Flywheel elsewhere.
