I plane on making one. So I was wondering if the the bolts could also hold ceramic fiber blanket because that seems like it would be even lighter even after coating it with refractory sement
crazyguy84 yes they will over time you will need to cover them with some kind of refractory cement. Or additional fiber and use sodium silicate to hold it in place
Thanks for the video! I will also be building one of these. Just got my stainless Frankie keg. about to order castable high temp cement. Drop me a line for chat of you have a minute. :)
looks good, I used to drill alot of stainless, mainly 316L and 304, and you defenitely need to run the drills slow. I used a corded drill with a router speed controller hooked up to it to slow it down, and that helpped a bunch, but I think the best thing that Ive found that helps is olive oil, lol. You may laugh but dip your drill bit in olive oil before drilling into the stainless and it'll just glide right through the stainless without much trouble. Also, I try to go 1 1/4 to 1 1/2 times the burner hole for the exaust hole because it'll actually expand as the gasses heat up and burn, and you want the bigger exaust hole so you dont run into back pressure. What did you use for refractory lining in your furnace? If your going with kaowool, you want to put something over top of it or it'll erode quite and spray fibers out of the exaust hole as it's running. Kaowool and other ceramic wools are very similar to asbestos, so it needs to have something over top of it to act as a hot face and to keep the kaowool from having any contact with the fire/air. The burner hole is usually around 1" off of the bottom of the furnace, so that the heat rises and heats the crucible as the fire swirls around the furnace. The voice in your video is really hard to hear most of the time, but other than that, good video, keep it up.
Chirpy's Tinkerings I have to finish uploading the last 3 parts of this build then I plan on making a cart for it and a hinge mechanism for the lid it’s heavy and a PIA to lift on and off every time I want to get into the furnace.. Thanks for being the the first person to watch it!
Chirpy any chance you have an email address I’ve got some photos of my first casting project with aluminum but something went wrong I think the aluminum is super grey and the ingots fractured in half for some reason what’s inside looks very “sand like” I used salt lite as flux and then what you recommended for a degasser.. Could it have been to hot??? Just looking for a little guidance
@@jrsemporium5579 Sometimes when casting in sand it picks up bits of it and you wind up with sand filled metal. That might have been the reason they cracked as it was cooling inside.
Ah! my bad. Might I ask where the metal came from then? It could be any number of things, like the aluminum oxidized as you heated it, or you used a weird bit of alloy aluminum that had something that didn't mesh well. BTW I love the channel. Surprised it hasn't gotten much more attention.
@@jrsemporium5579 I totally understand. And you corrected yourself. I have two and I always try to educate people who call them "big drill presses". It's like calling a plastic butter knife a Swiss Army Knife.
Liked the video but you scared the s*** out of me with that keg on the lathe thing.
Chad Keech lol!! It wasn’t the sportiest thing I’ve ever tried.. and I’m glad it failed when it did..

crazyguy84 they sure should if you use large enough washers to support the fiber!
@@jrsemporium5579 o ok but won't they melt from the fire if they against the fiber
crazyguy84 yes they will over time you will need to cover them with some kind of refractory cement. Or additional fiber and use sodium silicate to hold it in place

Alex F absolutely!! Thanks for watching!

Jake ZG those were poured directly into ingot molds the ones I had that fractured in half hadn’t actually been cast in sand..

6:25 What!!!? Never call that a drill press.
Henry Rak Part of a dying breed lol It’s “The Bridgeport 2” I just meant for people who don’t have access to one can use a Bridgeport..

Henry Rak Part of a dying breed 😂😂 yes it is...
@@jrsemporium5579 I starting my keg foundry today. So that's why I'm watching yours and the other guys videos again. Yours is sweet.
Henry Rak Part of a dying breed that’s awesome!!! Congrats on taking the leap!! If there’s anyway I can help just ask..
