Got an email response from Blacksmiths Depot, the 5lb bag they carry is 7.5"x5.5"x2", or 82.5ci. Hope this helps someone along the way. If using this information, I'd assume there's some empty space in the bag. Until I get the bag and actually measure the volume contained, I'm going to assume that the actual volume of material is ~10% less than the product dimensions. Will post back here with a rough lb:ci number when I have it.

Just finished my half inch burner from mikey's book, had to take a break from it for a while due to a broken sewer line, flooded basement, and some car troubles. Still playing around with tuning, but I thought I'd check in here and say thanks for everyone's advice, and see about any updates to the design as I'm planning to build another that's a bit cleaner, and I know someone said that there have been some changes made to the designs found in the book.

Hi, I'm looking to buy some satanite for the inside of a forge, but I can't find ANYWHERE that lists product dimensions or volume of material. I know I need 135ci, just trying to figure out if a 5lb bag is enough. If anybody has a bag (of any size, I can do the math to figure it out if it's not the same size) on hand and can post the dimensions here, I'd be much obliged. I don't have much extra cash at the moment so I'd rather not buy any more than I need. I have found numerous posts asking about how thick the satanite should be, but nothing that asks how much of it is actually needed to achieve that. Thanks a ton! - Nick

Just found a reference to the book Gas Burners for Forges, Furnaces, and Kilns, going to start reading that presently.

So, with some more reading, a few measurements, and some modifications (I have a TON of stuff in my garage, so I dont have to buy much at this point) I've shortened my nozzle, allowing me to use the largest fitting to sit in the set screws for some more adjustability, and moved it back quite a bit. I also cut some slots more forward in my venturi, as my fitting was taking up a lot of space. Burns MUCH better now. Thanks all for helping, will post new pictures when resized as well as my plans for the forge.

Went out and got a set of mig tips today, .023 set a little closer to the mixing tube is working much better.

Just got home from work, I'll go start reading and make a new design, thanks guys. I'll probably post the results of that tomorrow. Thanks for the advice.

Mixing tube is 8"×.75", jet is about 2mm, set inside the tube maybe a quarter inch. Venturi is a 1.5" to .75" reducer with four .25" holes drilled in it, tip is a 1" to .75"

Have not read that yet, will do so as soon as I'm outta work, thanks

Here's a picture of the assembled burner, albeit before I finished aligning the nozzle.

Hi, I recently built my first burner, it's a linear venturi style. I have two problems. Firstly, the flame is very billowy, not a sharp cone. Second, if my fuel pressure goes too high, the flame jumps away from the tip and goes out quite rapidly. I'm using a 20psi regulator, no gauge but I'd guess I make it to maybe 12psi before the flame goes out. I'm not sure how to solve either of these problems. The nozzle is centered and straight. I'm at work now but will post pictures when I get home. Any help is much appreciated. Edit: it's naturally aspirated propane
