During assembly, I needed to move my soapstone-clad Contura 820T a bit. I accidentally hit the soapstone top with my chest, causing it to crack. Many swear words! The break occurred right at the bottom of the U that the stone forms (the stone is placed like a U around the chimney).
Right there, where the stone is the narrowest, there was no support underneath. Maybe a bit of a poor design, but if I hadn't hit it with my chest, nothing would have happened!
Buy a new top, sure, but it's a waste of money. And I don't mind looking at a seam if the top can be repaired.
My idea is to glue a flat iron underneath for support, maybe drill and insert some form of rivet into the stone. Other suggestions? And does anyone have recommendations for a glue that can be used in this hot environment? I read about soapstone glue made from water glass, water, and soapstone flour. Does it work?
I accidentally bumped the soapstone top with my chest, causing it to crack.
Now, I don't know how powerful your chest is, but from the description, it sounds to me like there might have already been a crack or some other defect in the stone. Simply "bumping into it" shouldn't make it crack if it's as it should be. I would check with the supplier to see what they say. Then again, we might have different definitions of "bumping into," what do I know...
Well, hard to say if there was a weakening. I had a lot of clothes on, so I didn't really feel it until it was too late. I was honest when I talked to the dealer, and there didn't seem to be any help available.
Heat-resistant glue doesn't seem to be something that's abundant on the shelves in regular stores either. Does anyone have an idea of how hot a stove like this gets right above the enclosure?
Are you thinking about pannkitt? Yes, I have it at home but I don't think it glues very well. Maybe I'll place a couple of pieces of square iron profile between the stove and the stone halves for support. Just about a centimeter apart. Then maybe pannkitt might work.
There is glue for that kind of string you have around the hatch for sealing, maybe it would work.

Tips are gratefully received.
Aren't you afraid that the iron and stone will expand differently when you make a fire?

Yes, that is a thought worth considering! I'll probably build a small support of iron profile underneath so that the stone can move freely over it instead.
I found this epoxy glue that withstands over 300 degrees and seems to be available at auto parts dealers. But it was outrageously expensive. http://performix.se/jbweld
But you, a curious question that might provoke some thought.
What does a new toppsten cost?
What does glue, iron, and other "patents" cost, and still get a half-baked repair?
No, exactly. I don't know exactly how much the top costs but my guess is around a thousand kronor. Spare parts, you know.
I also talked to a chimney renovator who said that no glue can hold the täljsten together. Too porous. It will have to be a temporary repair and then buy new.
Otherwise, I'm a bit obsessed with trying to fix things before I buy new... And quite often it works, but sometimes you just have to give in
I am following this thread with anticipation. Is there really something to glue soapstone with? Soapstone in powder form is the same as talc, talc is used as a release agent. Soapstone is inert, does not change with heat or cold, it has no capillary action, it is hard yet easy to work with, a peculiar material. I have made some figures in soapstone, awkward situation when they break when you're almost done, I could also use a suitable glue.
I tried with cyanoacrylate EC100, seems to work, heated the piece to 150 degrees, at 140 the joint started to soften. But it is possible that there are better suited types of this. http://www.hweckhardt.com/adhesives/pdfs/Hight Temp.pdf
How hot can that stove get?
