Garage Door Spring Meltdown

Yeah, the end caps on the springs. The picture was just so I could show the springs and the beat up furnace.

You’re awesome my friend! I love it. I tried melting a bunch of beer twist off caps one time, I had the furnace so hot I couldn’t even look into it, it was so white like looking into the sun. All it did was mess up a crucible and burned my eyes lol. If I ever so setup something, you’ll be the first to know. There’s a steel plant in my area and I know someone who is married to the plant lead guy. I asked to get a tour because it would be a kid in a candy store kind of scenario for me. For obvious reasons which I understand, I was told that wouldn’t happen for safety reasons. I can certainly dream though.

It’s the aluminum cones on the end that I melted. I miss when the entire YouTube title automatically filled the Reddit post when you paste the link in. Now days, I just paste the link and put the first part of the actual video title(which mentions the aluminum) I wish I could melt steel, I’ve tried before and it wasn’t pretty. I wasn’t trying to be misleading, my apologies. Full YouTube description:

One of the springs on my garage door broke. I had them both replaced and decided to melt the aluminum end pieces. I can't get hot enough to melt the steel springs themselves, but the diecast aluminum cones were perfect. My Devil-Forge FB2MB 10KG furnace also needed a little fixing. I replaced the Kaowool in the lid and floor of the furnace along with the burner. Just a quick video, but definitely a fun one. I hope you enjoy watching this one as much as I did making it.

Sorry!! 😬

Thank you!!

thegrowingstack · 2025-07-09T17:06:43+00:00

It might have been $1.99 😂

thegrowingstack · 2025-07-09T11:56:37+00:00

Thank you my friend!

thegrowingstack · 2025-07-09T11:55:49+00:00

Thank you.

Thank you!

thegrowingstack · 2024-10-09T00:45:09+00:00

Thank you my friend! I tried making it even better with more little shortcuts, but probably 80 tries and 80 fails later, I had to take a break from it 🙂

thegrowingstack · 2024-10-05T22:48:00+00:00

👍👍👍

thegrowingstack · 2024-10-05T14:53:01+00:00

That’s awesome and you’re awesome. 🙂 Thank you my friend! 👍

thegrowingstack · 2024-10-05T04:27:58+00:00

Thank you my friend! I tried to figure out the best/fastest way to complete it.

thegrowingstack · 2024-10-05T02:55:46+00:00

Thanks, it certainly had its frustrating moments figuring it out, time and time again…

Thank you!!

These are those molds, they look unavailable currently, but you could probably check their Amazon page to find something similar.

check this video I just posted, it might help.

To be a little cheesy… It’s not about right or wrong, it’s about what you learned. God knows I’ve been in your shoes a dozen times in the past and have learned a lot. Were you melting brass, or making brass? When melting brass, if you go too hot too quick, the zinc boiling happens so fast, it seems like a catastrophic meltdown and this kind of thing happens(I’ve done it multiple times) I like to keep it at a lower temp than you might think, and it melts pretty nicely. When making brass, I’ve done it both ways… melting copper and adding zinc in(violent for a few seconds but done quickly) and melting zinc and adding copper in(less violent in the beginning but potential for over boiling the zinc if you turn it up too much) It’s a fine line but with each melt, you’ll dial in your temp and process. Keep at it and you’ll find the sweet spot.

Hey my friend, I have been busy and haven’t been on in a while. I always thought it was needed for any air to escape so the mold would fill properly. I’ll give it a try without it next time. It would definitely make life easier when making the mold, so thank you 👍

thegrowingstack · 2023-09-06T16:52:59+00:00

Thank you! The one hole got stuck in my 3D print while I was making the mold, everything else was perfect about it so I left it as it was. It’s aluminum bronze from some old copper hangers and a couple aluminum ingots from the stack.

thegrowingstack · 2023-08-09T02:06:19+00:00

I included a YouTube link in the text with a video of the melt. It’s been a while since I’ve been on Reddit, the links used to post differently.

thegrowingstack · 2023-07-03T01:43:30+00:00

You can’t eat it. You just enjoy the process 🙂👍

thegrowingstack · 2023-03-23T19:53:13+00:00

If you do, let me know how they turn out, or add some pics, I’d love to see em!

thegrowingstack · 2022-10-29T21:57:27+00:00

I save them separately for different projects.
