I had a guitar case once that had a smoke smell. Bought a small negative ion generator & put it in the case for a day...problem solved. I've kept it plugged in in the shop & when I open the door in the morning, it works so well I can't even smell the wood that's stored there.
Thanks for the comments, Michael. Yes, it is exciting. My crucible is stainless steel. There was no adhesion of aluminum to the crucible. As I reported earlier, I'm melting aluminum cans & pouring ingots for use in casting. On the first melt, there was considerable slag. Re-melts of the ingots have yielded nice clean aluminum. Would be interested in knowing what powder you're referring to. As Ken mentioned earlier, I'm climbing a steep hill & most of my current activity on this is educational. But I'm going to figure it out & get it right!
Hi, Ken, I appreciate the comments.
I like steep hills, I'm a climber.
At my age, having a hill to climb is part of what keeps me going.
New things to learn,
Lost wax is the method I'm planning on using.
I agree with everything you're saying, sir.
One of the reasons I'm progressing so slowly, at this time, is the accumulation of proper materials to do this & spending time to "study it as a science before attempting to practice it as an art."
Yes it is getting interesting & exciting for me.
Once I get a few things in place, I can provide myself a steady stream of realistic looking metal parts with which to work.
Then the real fun begins, I can start bolting this thing together.
The day job's been spilling over into my fun time again.
Did get this plug poured.
It will sit down in the furnace & the fire will be laid below it & around it.
The 4" stainless bowl will be the crucible in which the aluminum will melt.
By having a core that stays in the fire, the fire itself will not be disturbed when pours are made.
It's all about heat retention in the furnace.
I've done my homework on this over the past 2 - 3 weeks & I know that aluminum melts at 1220 f & that 304 stainless, which is probably the alloy used in my bowl, melts at 1400-1450 f.
So I've got a 200 deg window + - ? in which to work between melting alum & melting the bowl.
Will start the fire "cool" & slowly bring it up to the point where the alum melts & try to hold it at that heat by controlling air flow to the fire.
I'm continually impressed with the slick, polished surfaces I'm seeing in this.
If pouring a refractory mix gives me this quality finish....I'm really hot to see some poured aluminum model parts
