thanks Larry, right into the morning today I still was wondering what to expect.

Plaster slowly warming up another day and it will be there as a monster heat sink and close enough there are no more drafts even with single glazed windows. Personally I would be very interested in your center stack temps vs. barrel temp. The problem I have with skin temps is way too many variables involved to get an accurate number. Gas temps dead reliable even though most don't use them as don't want to spend the money for a probe. I have given some serious thought to adding a Magic Heat to add some heat exchange area and while not as good as yours closer just worried with the large rectangular grates if it will turn down enough is it gets into the 40's. With a rounded off 570 on the barrel hope you have well under 20F outside or a large house as sounding like you have a heat monster and great success! Good for you when hard work pays off!!!!
thanks Dave. it was 25* OAT when I started this morning. the house was 68* inside. by the time I was done with the switch and starting the new stove it was 58* inside.

now it's 17* OAT and 62* inside. this is well inside the comfort range for us.

Sounds very promising and sure do hope all works out sounding like a path for success and a good thing. I am betting a full load will be epic!

from here on, during the rest of the night the house will pick up about a degree an hr. till it gets to about 70-72* by morning.

considering that the stove is barely 1/2 full, running so slow and still nudging the 5:1 ratio i'm sure I have nothing to worry about this winter.

I've been following this project from the beginning. Going by what you've detailed and explained, and what I saw in your pictures, I saw no reason to have doubts about how well it would work.

Great job, Steve !!!!

the real mystery all along hasn't been if the stove would burn and heat but what the running / tending characteristics would be.

this stove works somewhat differently than the last but I've got it about figured out.

before bed last night I had torch blue flames coming up the chimney bricks. I tried for 1/2 an hr. to get a pic but just couldn't get the camera settings right. that will probably be something i'll have to get on a vid.

stove was running fine this morning. I put 24#'s of coal in this morning to form a slight mound with the outer edges at the top of the lower bricks and the blues were still rolling when I left. what shakes out and gets added tonight is going to be pretty interesting. very little came out this morning and it was all dust.

What, with all the free wood out there, who's going to like something that uses 24 lbs. of coal over night and you can ignore it till just before your out the door for the day and then once more again after supper?

that's kind of a misconception. it didn't use anything like 24#'s of coal over night. that's just what I put in, i'm still loading more than was used to build up the fire depth.

from the looks of it this morning it was ignoring the coal all night and burning the mouse turds in between.

Buck was using 20#'s every 12 hrs in -14* windy weather last winter and it wasn't a base heater.

it will probably take the rest of the week to get a decent handle on what's going thru it per tending or day.

This is awesome to read shes up and going, cant wait to here the #s. Glad to hear everything is going as planed, congrats on the new toy......

so from wait I gather this stove is modeled off a locke 120 with a base heating chamber, not a suspended fire pot?

Yup that first 24 hours is pretty much meaningless for judging coal useage. My range always uses more coal during the first fill and 24 hours than the daily average thereafter to refill what's burned.

Filled up last night at 6 pm and tended at 7 am today. 12 lbs. is all it wanted and did spend plenty of time shaking and clearing the grates from below. I have been carefully figuring out where the ash mainly is and where I have been missing and found the front and rear edges have much more than the center as it is there but not as much. I think in my stove the bridging starts at front and rear edges then grows to center. I can see a round fire pot with fewer edges makes a bunch of sense. My weather 30's and 40's with a light breeze predicted to be the same until Thursday and Friday then colder.

I would be very interested to see how much you burn over a week and taking notes as to temps and wind might be helpful or it access to degree days useful too. This has me wondering where I can find degree day info.

Next project,
"Base Burner Furnace"

OR how about a base burner boiler?

it's taken forever it seems to layer nearly 100#'s of nut into the stove and of course the closer to full it gets the more the operational strategy changes.

finally running at -.03, steady blues and great heat on very little primary.

579 / 117

Are you in baseheater mode?

yes. stove hot spot is 579 and the stack at thimble is 117. sides of base chamber 186. FRANKS base was 3/16" steel and was never that hot at the outer surface.

Does it look possible to cut it to -0.02 and keep more in the stove this is sounding like working really well! Same amount of air as primary has to open but lingers 33% longer.
