This makes sense. Based on the posts, I was wondering if the fireclay/sand mixture created some unknown amazing insulation that I wasn't aware of....
I've been reading through old posts, and ran across a couple mentions of using a sand/fireclay mix behind the hot face and for the floor. I...
I haven't worked out the fuel and air adjustments yet, but you're spot on, they certainly need to be above ground level. I'll work on the overall...
Good points. An open space around the furnace makes sense. This would make it much easier for maintenance, as well as manage the air and oil...
Putting up a wall is the first option, but I want to ensure I look at all my options before going forward. The ground here is a fine layer of...
My wife has finally accepted this as my hobby, and has offered a dedicated place in the backyard for my furnace. As such, I'm trying to play nice...
I took on a new project just in time for spring. I am attempting to modify an old pool heater to burn waste oil instead of expensive propane, and...
I initially bumped into this same problem. I could reach higher temps quite quickly with a couple of stacked firebricks in the furnace, but...

This makes sense.. I see I have a couple of new things to try. I inadvertently experimented with a solid stream hitting the hotface when my siphon...
After testing various burner options in a couple different furnaces, I wanted to try a pressure nozzle and eliminate the need for an air...
Creating an airtight seal between the body and lid is something I have struggled with. I like this idea, but would hope to find a more permanent...

My siphon burner finally arrived and I was able to get her setup and burning. It took a little more work than expected as I ran into a few...
At what furnace temperature can you switch over to wvo? I'm still running 100% diesel while I troubleshoot this beast, but hope to move to wvo in...
I built this furnace from an air compressor tank. I cut off the top, welded in a number of large fender washers, then followed the same kaowool...
It's been a busy week, with some successes and some failures. Although anytime I learn something I consider it a success. I made a disc with a...
My furnace ID is 9" and 14" in height. I have a built-in plinth that is an inch or so tall, and spans the width of the furnace. I also place a...
I recently removed the ribbon burner and piped in a 2" tuyere for testing. I remember typing this into my first post above, but there's nothing...
Going back to my current furnace, I have spent upwards of 35 hours of burn time trying to tune it, with no real progress. I should fill in more...
