Welcome aboard, glad to have you. We don't care if you're not a blacksmith. . . Yet, we'll talk to anybody.

Two thoughts for you. First, you can buy small quantities of 3,000f water setting castable refractory from Glenn in the IFI store. It sets and cures concrete hard, a 1/2"-3/4" thick layer isn't going to care how many pellets fall on it or how hot it gets. If you melted the stove the Kastolite would survive. At worst it aught to sound like dropping pellets on a concrete floor.

Refractory cement or mortar isn't likely to last very long, it's not formulated for flame contact. You want a straight up castable refractory and you don't need to care about forge welding flux dissolving it so any will do. You just want something that cures hard and strong, some are pretty friable, I'd avoid those.

The other thought is wrap the outside of the fire pot with a suitable refractory, say muffler tape or refractory blanket. It will kill the ring but might not deaden the tink enough. Heck probably won't but what the hey it MIGHT work.

I know about the TINK. I'm a TBI survivor and suffered nerve damage to my left ear in the accident. Audio recruitment has seriously screwed up my hearing on the left side. I can hear you talking but probably can't tell what you're saying. Drop a single piece of kibble in a stainless dish and it's like driving a spike in my left ear. It's a funny thing, some sounds are painful, others not at all, heck hammer on anvil isn't bad but just talking about dropping a wood pellet in a steel pan makes me cringe.

We'll get something figured out, stick around. Heck hang with us and we'll have you blacksmithing in no time. It's addictive you know and we love helping folk get hooked.

Thank you for all that info, it’s very appreciated. So with the kastolite 30 I’ve read a few things. Would 24 hours of air dry time be enough to put it back into the stove and than the stove could heat cure it the rest? I can’t really adjust the temp of the stove easily for specific curing. 

I think this will just deaden the sound and I’ll be happy with that. Sensitive hearing is funny, most people don’t get it and just say you’ll get use to the sound. I appreciate all you guys really trying to help me find a solution.

as far as blacksmithing, I’ve totally thought about it after reading all this info. Looks really cool

The manufacturer doesn’t really encourage any changes to their firepot lol. I’ll work on some pictures

Good idea. I think I’ll be happy with more of a thud sound than the tinny sound of hitting metal though. Even the insulation wasn’t silent but it dulled it enough that I was happy with it

You guys are definitely pointing me in the right direction, should I use the premixed castable cement or the dry one you have to mix? I think the difference is in the cure. I’m not sure I can cure it correctly in the pellet stove.

No offense taken at all guys, I know it’s a different topic than you guys are use to, ive just read a lot of good stuff on here about the forge making but still need little direction

Is it a tinging of the pellets hitting metal, or is the thud of them hitting in general that is the issue? If just a tinging, then maybe a properly rated castable refractory might help.  Thats about all I can offer. 

It’s the tinging of them hitting metal. You think a castable refractory over the insulation?

you are aware that this is a black smith site?

I do, but every time I searched ceramic fiber insulation I came to a site like this, maybe my limited knowledge of this content led me to post in the wrong spot. My apologies

Hi all, I have a wood pellet stove for heating my house and stumbled upon this site while trying to solve a problem with my stove. The pellets dropping into the firepot are very loud, and I’m also sensitive to noise and easily annoyed lol. So since it’s a clanking noise from the pellets hitting the metal firepot I’ve been attempting to line the firepot with something softer.

first attempt was using ceramic fiber board with gasket cement. Initially worked but became brittle soon and flaked off with minimal pressure.

second attempt was using ceramic fiber insulation with sodium silicate. This also worked well but only for about a day. There is one spot in the firepot, exactly where the pellets hit, that just burns away and the noise comes back

so is there something I can put over the ceramic fiber insulation to make it last longer? It says it’s rated for 2300f but in this one area it burns away

there has been no negative impact from this on the burning of the stove since I don’t cover any air holes 

open to any suggestions from you fire gurus, thank you
