Alright, thanks for the tip.

I see what you mean, that seems good. I did finally manage to find some cheap bricks that I'm picking up Monday, so we'll see then.

Sorry, I've been reading a ton of these recently and got it mixed up What kind of angle should I set the burners at? Is there also a golden ratio for how far from each other/the ends of the forge they should be? Should they be parallel to the base of the forge? Hefty suggested perpendicular to a brick, but that leaves a lot of leeway for error for me

well, for the smooth interior, I was thinking of sanding/grinding the bricks for that, and about 20 bricks to err on the side of caution, as the math I did got me 14.86 bricks for the sides, and then extra for the doors. I don't exactly know how I'll affix them, probably with bolts and strips, and the innate integrity of a semicircle. Always open for advice/being told what I'm planning is a bad idea etc. I say with bolts and strips because somebody said not to use mortar on the forge due to expansion in the high temperatures. There is an outlet of the HWI pretty near, but I'll wait till tomorrow to call them.

looking online, I'm seeing that the firebricks aren't too expensive, but the shipping on all the suppliers I've looked at so far doubled or over the price on shipping/handling. Any advice on where to get the bricks without paying exorbitant fees?

Well, as it is a semicircle, the calculation should be (pi(6^2))x12/2 at least that's my understanding of it, thanks for your patience dealing with noobs like me. So assuming a semicircle, the volume calculation should end up just below 700 cubic inches, sorry for not specifying that

and a depth of about a foot so, a total of about 700 cubic inches

What I meant by medium is larger than just a knife forge but still efficient, as I am a bit cost conscientious. So somewhere around a 6" radius

Alright, thanks Hefty. Any specific drill for the firebrick?

I'm planning on building a medium size forge, not just for knives, but also wider workpieces. My primary concern is how to affix the bricks, as I could find no info on that searching this site. My burners are 3/4" A D-shape (or vault) would be preferable, as I understand it, but whatever you experienced folk think is best, as I've had no prior experience with propane forges.

I'm looking to make a new propane forge, and while I saw brick pile style forge, I would like some advice for the construction and materials. I saw in another thread the Morgan Thermal Ceramics K26 firebricks, and I was wondering if there is a specific size that I should use, as well as the ideal measurements for the forge. I plan on using two Frosty T burners, as I already have them. I live in the US, so I should have access to the same suppliers as most of you do. Any help would be appreciated, I'm currently at a standstill trying to make a good forge for cheap enough I can afford it.

Frosty, can you repost your forge plan? It seems to fit my purposes for a forge exactly, but now(14 years later) the file cannot load.
