Forget the polish! Heck, forget the paint and coatings! Fire it up!!! :lol:
Just kidding Scott. You're doing a great job, and Cindy will keep you guys warm this winter. December is here. You got the end of the month to worry about. Guts to get in that mode now. (I'm not one to talk).
Bye the way Scott, will you be putting a magazine in that Stewart? Looks like a perfect candidate with that shot-gun barrel. Maybe we already discussed this a few pages back.

scalabro wrote:Well, I was wondering if that question would come up. Here are the measurements, it's close.

Don't forget these are just barrel surface areas.
The back pipe on the Stewart is 36x6.

Crawford 40
Grate = 11 inch diameter.
Barrel = 28 high X 52 circumference (barrel is oval) for a barrel surface area of 10.11 sq ft.
Fire pot = 11x10&1/2 to the bottom of the load door (998 cu in).

PP Stewart 14
Grate = 9&1/2 diameter.
Barrel = 36 high X 44 circumference, for a barrel surface area of 11 sq ft.
Fire pot = 9&1/2 X 13&1/2 to the bottom of the load door (956 cu in).

The C40 has a slightly larger pot and is a "full" base heater. The Stewart does not have gas flow beneath the ash pan, just down the sides...like a Glenwood 109, 111. It also has a far smaller load door than the Crawford. However, the Stewart occupies slightly less floor space.

BTW....the Stewart does not appeal to the Lady of the house...uh oh!


This made me curious about the Chubby which measures in at about 12 sq ft. I guess short and fat is deceiving. No backpipe but I have 3 ft of exhaust pipe with fins. Firepot around 740 cu in so the tall boys are dominating there. The fat nature of the beast, however, allows for substantial coning.
The heat transfer to the room is complicated. For the Chubby most of that occurs on about 50% of the barrel surface that is hottest. For the tall boys I think the hot surface is much smaller but then there is lots of transfer over a larger cooler surface area. Don't get me started about efficiency which is pretty much impossible to calculate. I think a sensibly run stove with cool exhaust is around 90%.

Oh boy this has the potential to get "heated" real quick. :o Might need to move this thread to FSC...... :lol:

Though I will always refer and bow to Lobsterman and his number crunching ability.

Before this goes anywhere let me state that the turn-of-the century base-heater classics are the finest anthracite stoves ever made and would cost a fortune if made today. End of story, and this is why the following is so strong.

Nice, Scott.

Is that going in Laurel, or Hardy ? :D

Interesting how they used such long tabs to join the two halves. I wonder if they didn't want bolt holes near an edge to risk cracking ????

Sorry I may have missed this but Why did you coat the pot?, are you running brick as a insulator?

Haha! Laurel :D

This is a fabricated ( 1/8 inch 1025 steel ) copy of the original that was burnt out. So those tabs were installed to hold the three separate pieces together. Originally it was held by cast in tabs and hooks.

No I'm running refractory bricks supplied by Skip, but since this cost a pretty penny to have made I thought it a wise investment to protect it from corrosion.

So today I got to thinking ...

:o :D

I put this 6 inch oval MPD at the base of the back pipe. It's my opinion that it will slow gases further increasing the time they are in the stove to shed more heat. It's in addition to the 6 inch round MPD in the stove pipe about 24 inches away.

Opines from you fellow base heater freaks please... :lol:

You might have put it as high in the pipe as possible and added that much more radiant surface under the first damper but it will work fine as is

KC,
That would be ideal if I vented out the top of the back pipe as originally intended, but my install vents into a fire place so my options are limited :cry:

Pauliewog,
No it's an old Griswold damper.
