VainEnd84 Posted June 9, 2017 Share Posted June 9, 2017 I started planning my forge build about 8 months ago when it was still too cold to build or really spend any extended amount of time outside. Well it's summerish here in the great white north so I could finally build my forge. Here are the spec, the shell is made from a 5 gallon auxiliary compressor tank that I got for free, it is lined with 2" kaolin-2600 ceramic blanket, which has been rigidized and coated with a castable refractory. I was asked by the person who sold it not to name it because it is still in the process of being patented but I can say it is similar to plistix. I will be using a 3/8" kiln shelf as the floor. I am using 2 1/2" Frosty T burners. This is a quick video of the first firing of my forge, a few notes: - I know I need to tune the burners - that is not the table it will be mounted on, mostly because wood burns and uncontrolled fire is bad - it reached an incandescent heat in 5 min running at 10 psi - I know my plumbing is ugly, but I works and that's what matters Quote Link to comment Share on other sites More sharing options...
VainEnd84 Posted June 9, 2017 Author Share Posted June 9, 2017 I do have a question, should I use fire brick to close the back or would kiln shelf work? I have a bit of 1" kiln shelf that came with the thinner stuff I'm going to be using for to floor (I got it on kijiji as a lot) Quote Link to comment Share on other sites More sharing options...
jcornell Posted June 10, 2017 Share Posted June 10, 2017 kiln shelf makes a fine door. If you have some channel iron to serve as a track, it's a dandy solution. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted June 10, 2017 Share Posted June 10, 2017 Nice job so far. Do you plan to make an internal movable wall, so you can just run one burner, whenever you don't need all that space? Quote Link to comment Share on other sites More sharing options...
VainEnd84 Posted June 10, 2017 Author Share Posted June 10, 2017 I certainly am planning on making an internal wall. I have some soft fire brick, the 1" kiln shelf, and some left over ceramic blanket and refractory, what would you suggest I use for the internal wall?

Mikey98118 Posted June 10, 2017 Share Posted June 10, 2017 High alumina kiln shelf is hard to beat for external baffle walls, and for internal movable walls. Quote Link to comment Share on other sites More sharing options...
VainEnd84 Posted November 13, 2018 Author Share Posted November 13, 2018 So, I had been having issues with getting my forge hot and anything less than 15psi, So I went back through the T-burner thread and the forged 101 and burners 101 threads, and I rebuilt my burners and relined my forge. I made new jet ejector assemblies to hold the mig tip dead centre, my first ones were misaligned just a bit, and I cut down the mig tips a bit shorter than last time. I replaced just the inner most layer of ceramic fibre blanket and put new cast able on the entire inside, as well as casting a removable floor from a bubble alumina cast able, and gave the bottom a coating of a kiln wash ti increase the flux resistance even more. On the whole it looks basically the same, but holy cow does it work better! Prior to the rebuild I was getting up to about 1800F at 15psi, now I'm hitting the maximum temperature range of my thermocouple at 10psi, that's 2750F. Now it's a cheap thermocouple and cheap display, I probably spent like $25 on the pair so I wasn't convinced that it was all that accurate. Wellp, I was forging an oldish jackhammer bit in to a chisel and got side tracked for like 10min, also having forgot the my regulator was set to 12psi, because I was practising forge welding earlier. I took out the jackhammer bit and low and behold the tip is burnt xxxx near off, and melted a hole in the kiln shelf I was using as the back door. So I guess my forge does get that hot... now it runs at 1500F at ~1.5psi, though it will only run like that for about 7or8 minutes before the burners start popping and farting. And I dont dare run it higher than 12psi because I feel like I might actually melt the inside of my forge. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted November 14, 2018 Share Posted November 14, 2018 I would like to see you feature the new forge in the Forges 101 thread with photos and a write up about it, including the changes. I like the design and size; it deserves to stick around when this month is over with, and I think its addition there would be a service to people searching for good forge design ideas.

VainEnd84 Posted November 14, 2018 Author Share Posted November 14, 2018 I certainly can do that, though it will have to wait for the weekend as I wont have a chance to get to my shop until then. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted November 15, 2018 Share Posted November 15, 2018 Excellent; I think it will make a fine contribution to the Forges 101 page Quote Link to comment Share on other sites More sharing options...
