JHCC Posted July 5, 2018 Author Share Posted July 5, 2018 I’m toying with the idea of making this into a gate that can be flipped up or down as needed. I’ll post a picture if I do. Quote Link to comment Share on other sites More sharing options...

Lou L Posted July 5, 2018 Share Posted July 5, 2018 Wow, that’s a great idea. That one goes in the mental scrapbook for sure. Quote Link to comment Share on other sites More sharing options...
JHCC Posted July 6, 2018 Author Share Posted July 6, 2018 Another observation: switching to bituminous eliminated the problem of clinker forming around the tuyere; it now forms almost entirely at the bottom of the firebowl, and there's a lot less of it.I'm wondering if the anthracite has a higher silica content? Or if the higher heat was melting the sand around the bowl? Food for thought.... Quote Link to comment Share on other sites More sharing options...
Lou L Posted July 6, 2018 Share Posted July 6, 2018 This problem with anthracite has been a thorn in my side. It is manageable but I hate how the ash and clinker surround the tuyere. Soon I will be making the drive to buy some bags of bituminous to run a test of how it works in my forge. I’ll accept clinker buildup on the bottom of the fire pot all day as long as I can create the high fires I do with anthracite. Hoping to get some bituminous before your visit. We shall see.

JHCC Posted December 27, 2018 Author Share Posted December 27, 2018 Couple of updates: the hood was sitting right on top of the fire, so I added a short section of heavy pipe (actually a piece of scuba tank) to lift it up a bit. Interesting to note that the fire burned a hole in its front, but not the front of the tuyere: a convincing demonstration that the water-cooled tuyere is working nicely. I also just added some pieces of 1” thick chimney tile as a sort of “deck” around the outside. This should alleviate problems with the sand getting mixed into the coal. Also added a deadman switch with safety cover to the blower. It’s just on/off, though, so I’m still using the variac to control the speed. (Another good find from the industrial surplus place.)

jlpservicesinc Posted December 28, 2018 Share Posted December 28, 2018 John it might be time to look at installing a better stack.. Your forge area looks a lot like mine when I forget to close the door and it's windy.. I must have started the fire with a bunch of leaves more than once..

JHCC Posted December 28, 2018 Author Share Posted December 28, 2018 Don’t worry, the leaves all get swept out before the forge gets lit. Today was a no-fire-in-the-forge day. Quote Link to comment Share on other sites More sharing options...
jlpservicesinc Posted December 28, 2018 Share Posted December 28, 2018 Sorry, it wasn't meant to sound above the leave thing or a fire hazard.. I just thought it was funny since I work in a trailer and only have the back hatch open this time of year yet on 2 occasions there were enough leaves inside it so I could start the forge..

JHCC Posted December 28, 2018 Author Share Posted December 28, 2018 No offense taken. Leaves are funny, though: they only start fires when you don’t want them to. Quote Link to comment Share on other sites More sharing options...
