Glenwood #8 Long Burn

Pancho wrote:Food for thought. Cast iron pipe:

Cast Iron is the premier piping material for sanitary and storm drain, waste and vent applications. It has been used in these applications for hundreds of years and is for non-pressure applications where temperatures will not exceed 212° F.

It is the most durable DWV piping system available and can be used in all types of construction. It has high crush strength, is noncombustible and offers superior sound-deadening performance.

That said, I have made firebox parts for my old woodstove out of commercial hot roll steel.......that is NOT the way to go.

Yeah, hot rolled can be nasty, but I wouldn't even try cold rolled steel for this type application - being that it would be in contact with the coal bed. I think it would be badly burned up at the bottom within a few seasons. Not good to have a magazine that could get shorter and shorter.

Might it be possible/easier to instead modify or re-make the top supporting flange/plate to be able to then adapt a more common newly re-cast, split and bolted magazine...of proper length etc.

Yes, that's another possibility - machine a reducer ring. But, to fit what ?

My hot roll back plate (I went with 1/2"thk) didn't even make it through one season.
Any idea what material steel stoves are made of?....it's got to be something other than 'regular' cold roll....maybe a heat treatable steel?.
If a fella knew what material that was, he could build a prototype (have it rolled) fairly easily. Heat treat wouldn't be an issue other needing to know what it needs to be treated to.

No idea what type steel they use to make modern stoves with.

And, I'm no longer in contact with my, now ex brother-in-law, who was a metallurgist for Combustion Engineering in Conn. Having worked on designing nuclear reactors, he'd have been a good one to kick these ideas around with.

Fit What?...
Locate a Donor Magazine that will work in the most stove platforms possible and have it replicated for the masses. (all 4 of them)
Then it would only need a little help from an "Adapt-A-Kit" to make it fit. (Johnny Cash)

A Donor Magazine that was longer would work better, cause one can alway shorten it to their particular stove's required length.

Yeah, he'd probably had some indications on which way to go with material.

Welp, if I had a drawing of what we've been chatting about, I might could get one made up for a template. I've never seen a magazine in a stove or in my hands (they are the things of lore) so I am of little help.......but.......if'n I had some pics with some theory, I think we could get somethin' made up to use as a buck for casting. Dimensions are always helpful.

For applications in these stoves where the metal is in close contact to the fire, like grates or the magazine. The cheapest metal that works well is cast iron. There is a specific ASTM grade of cast iron, I have to look it up but it's too late right now... It's better than any of your steels or common stainless steels...

So who has the lathe where we can turn a nice piece of wood and make a model? All the old molds for these were originally done in wood... you can use lots of different materials though... You take two pieces of wood and mate then down the middle. Then turn the shape inside and outside. When done, drop the two halves apart and you have the two sides of the magazine mold.....

dj

The wood turning trick is to glue the two pieces together with a thin sheet of paper in-between. Turn the part to shape.

When done split the part at the paper seam, which tears apart much more easily than the wood.

Scrap the paper and glue off and the two halves don't loose any noticeable dimension from a saw kerf.

To turn the inside and out that size you'd need an expensive bowl tuner's lathe and chucks.

Paul

All one needs is a Donor Magazine...lathe talk is nice , but it will stay stalled there as talking point forever. Let's Git'er Done!

Notice the split halves. Inverted funnel/flair over the fire.

I also noticed why so few still exist. They are far too light. the bottom should be much thicker, at least 3/4 inch thick.

It may or may not make a difference...but the 2 pics above are actually from, I believe, a bituminous coal stove magazine...so may not be a good representation in all aspects.

Surprised Auburn doesn't have one available. It seems like they would sell. I'd like to put one in my upcoming Crawford 40, but I don't know if one was ever offered or it's possible in that style stove.

I made one for the Golden from cast iron water pipe just to see if it would be useful but I didn't burn the Golden very high 125/150 F, and didn't see a great difference with or without it.
Before investing a lot on a magazine, find an old cast iron pipe having the right diam. and weld a top retaining ring can be made easily.

Beautiful Nortcan!

But why did you not open up the throttle a bit more?

The little Golden lives in a small 10 X 16 living room so it was intended to heat that always cold place. But since the Sunnyside replaced the Vig ll, no real need for the Golden. In fact the Sunny can heat the entire house ( 3 floors) at about the same temp. in every room without difficulties. Much more than I dreamed of.
