Well, that entire coating on the lid came off in chunks after 6 hours of firing, the other fire mortar worked much better. Furthermore Al203...
I hear ya and completely agree about the thermal insulation bit, we can consider this an experiment to see how it will last. :D Finally put the...
Thanks! Haven't gotten that far yet, I've predrilled holes through the insulating fire bricks and rounded over the edges so I don't have a sharp...
Checked through all shelves, there's some splatter but removed anything that could interfere with placing my heating coils. Don't want to prod...
I will make some thin steel bands to go around this then try to lower it down into the 'old' furnace and fill the voids back up with perlite,...
Thanks for invaluable tips as always! Tried mortaring everything together yesterday, we'll see how it holds up. I dipped the bricks in water...
Been trying to understand the document, thinking out loud a bit. I think my wall loading should come out to around 21kW/m² with some simplified...
3 phases where each leg is 230V relative to neutral. 2 legs are 380V RMS between eachother at highest point. If I remember correctly I both...
Good tips, thanks! Haven't had time to use it much but finally started making aluminium ingots. After maybe 10 hours of runtime I burnt my coils...
The pins are threaded and are holding both halves together, a bit of a nuisance to bolt together but makes a fairly solid box. :)
Finally up and running :D Large amounts of water/steam kept creeping out as I ramped things up. Raised it to 100c until it stopped steaming then...
Real good info, thanks! Slower than I hoped for but as long as it can get up to temp it's not an issue for me. If melting and casting becomes a...
Ah sorry, I missunderstood. The bucket has ~45 liters of perlitecement and 10 firebricks. With the lid, once it's filled in, this should come out...
Smoking shoe: Good ideas! Not sure how I feel about having a hole/plug in the top though, it's pretty fast and easy to just slide the lid and...
Little bit more progress, quite a lot of hours for so little visual progress. Spent probably 2-3 hours on the lathe just making this purely...
