:/



im not sure what the clown is using in his aluminum unit and frankly i would steer from anything he is using. i would recommend the soft IFB i mentioned if you want something to use. yes the soft stuff can be hacked away with a knife or rasp.

I clicked on the kaowool, and right beside that stuff is some very cheap "super-wool". It looks promising as far as heat and temperature resistance, and its thin also.

Satamax said you have to be careful with ceramin fibers and your lungs, but the same rule applies with the fiberglass I sometimes work with, and I do have a decent cartridge respirator mask.

The the super-wool also good if directly in the path of the flame also?
Its hi-temp for sure

i dont know much about the super wool.


maybe you should delete the aluminum rocket stove video thread bro before it ends up being the "curse of John McDoodle"?

John, i've heard, that's not first hand informations. That cerablanket can go through your skin, and since it's not bio soluble, it stays there, and could cause cancer years later. True or not, i don't know.

Beter stay with superwool and the likes.

You are refering to my "insulation help" thread? I've already marked it as "resolved". They don't give many (or any) delete options that I can find on my blackberry mobile site, or on my microsoft browser either. I would delete it if I knew how.

Remember to stay on topic. That post topic is not about metal or aluminum, its about help with identifying insulation

Here is a preview of my new pellet burner.

This is not my design, its been tested, and I'm not yet completed with the stove or the new pellet burner. Just a preview of my latest efforts and experiments. When this is done, I will see if I can melt my new replaceable stainless riser liner lol.

I'm also looking into some of that superwool insulation for inside my burn chamber, just in case.

After seeing other peoples steel depreciate, I want to keep mine protected. So for preventitive maintenance measures, I will line the inside of the burn chamber with a thin insulator similar to the "insulation help" thread, hopefully.

Oh snap! I decided to drag my lazy but out to the shop on this rainy january day (kinda odd here, supposed to turn into freezing rain tonight) and I got some more development accomplished on the jet-style pellet burner/ gravity feeder #2.

Some photos, I bet T2H (the jet fuel burner designer) and Rom1nb (the original developer and tester) would be proud of this puppy. Internal tube is Hi-nickle 3" hi-temp exhaust pipe, and the outer pipe is 4" aluninized diesel truck exhaust pipe, also hi-temp.

come on brother, you know i had to take a jab at the aluminum stove... i couldnt help it, its in my DNA. stay on topic. stay on topic.

ok your stove looks pretty cool and im trying to figure out how you fill it? does it pull out like a drawer? why no pics of it burning. you were so close all filled up but not one pic of you sticking a lighter in there.

I have photos and videos of it running durring short tests. I posted some youtube video links of it running on pellets, photos of it running on wood and pellets. Photos of blue in my flames, all that. Just check pages 1-6 of this thread for photos and videos of it running nice and clean,

there's even a photo of it smoking too, because I even post my fails and setbacks and I like to post ALL the info, good or bad. I've had 2 setbacks so far, fiberglass liner, and cast riser, but they are both gone now

Check my youtube links brother

Peace love and positivity

To fill the stove, there is a vertical 5"x5" feed tube. You can fill it with wood up to 20" long safely (or longer if you wanna babysit the stove) or you can fill the same vertical feed tube with pellets, when using one of my pellet burner components.

The feed tube is 17" (12" + 5") long/deep, allowing for standard 16" long sticks/logs, but it will handle 20"+ long sticks fine. If I continue pellet experiments, I might make a feed tube extension, or pellet magazine, or funnel for even longer unassisted burns. It has burned for 3-4 hours on less than a full feed tube, about 3/4 full, and it was still burning when I walked away from it, so its very efficient with the right pellet burner.

Anymore questions let me know

If you are refering to the NEW jet burner, I have not finished it yet, maybe tomorrow

Well its like a blizzard out here again today, I didn't have time to work on my pellet feed yesterday but I'm making some progress today, adding some square cil plates so the pellets will gravity feed into the jet burner properly, the way I want them to. I figure this burner will be even more efficient for consumption rates / burning rates of the pellets.

More development photos to come soon

feed tube is about 17x5x5" so it holds 425 cubic inches i guess... about 6-8 hours worth possibly, i have not tested a full load yet, but earlier in development i tested less than 3/4 full and it burned for 4+ hours on my original pellet burner. i need to do more testing yet i dont know much about it, im still learning on it and im not done developing the prototype stove or the new jet style pellet burner either.

I'm I'm not the type to chooch my own antler, but I'd have to say it does have good capacity and long burn time. I'm still on the first bag of pellets! That's pretty epic economical compared to other people's pellet burn rates, I think that bigelow farm guy said he burns 8lbs per hour! Mine is way more economical than that, but I'm still just testing and developing and having fun, when I'm closer to finished I will give some better numbers, make timers, start from cold, take measurements etc. I've seen other peoples startup videos where you can see the ashes flying upward before its even lit, so you know the riser is already pre-heated. I like how Rom1nb shows you the temps on the stove and waits for everything to cool down before doing more testing. Pre-heated stoves and risers help a lot for fast lighting, but in the real world that's not always practical, sometimes we have to start our ice cold stoves from sub zero temperatures.

I'm really excited about this stainless liner, it is very easy to work with and it could be changed every year if need be, like a furnace filter. I'm still experimenting

I promised a dutch oven, so my removable lid that everyone may be familliar with, will have another removable lid, like a BBQ lid, that can sit on top of the stove lid. I want to use a BBQ lid, but if I can't find one with the appropriate size and built in temp gauge, I will have to fabricate one. I'm suprised nobody asked about the dutch oven yet.

Pellet-powered, jet-fueled, rocket-boostered, dutch-oven, with internal mass, space heater, and cook top? Sure, why not?

cheers

Oh snap! NEWest VIDEO went live today!

This video breaks all my records for LEAST amount of curse words lol

Check my youtube or click the link

https://www.youtube.com/watch?v=vmhq_3-PsPg#

Also, later today I fired-up the stove to show my friend, first fire since I cut the stainless riser liner to fit the lid on and such.

I got 500 F on the digital laser gun with the thin-barrel-style lid within 10-15 mins. That's fast for cooking/preheating.

It lights pretty fast and pulls fast even from sub zero canadian weather. Today it was around -10 or -8 C at the warmest parts of the day, pretty frosty.

I have more "show and tell" videos to post on my testing and readings and findings today, I've even slowed down on cursing and moved all the gas cans lol

Cheers

Well its going to take 145 minutes to upload a 10 minute long HD video, which is progressing as we "speak". This is my newest and longest video I've shared thus far using my HiDef "go-pro" action camera, getting temperature readings within the FIRST HALF HOUR of a sub zero start, talking about my future dutch oven ideas, quick look at modified firebricks, doing a show and tell on my old coleman camp oven, talking about the two pellet burners, and a guest appearance from my dog Ryder Fluffypants.

Video should be live around 10pm eastern standard time tonight. So about 2+ hours from posting this update. I will post up the link when its done later tonight or tomorrow, or check my youtube after 10 pm EST.

Calculations, findings, numbers: tonight using my very simple original pellet burner, I burned 5 3lb tubs of pellets. These tubs hold 3 lbs of concrete, but pellets are less dense, so I will say each tub held about 2 lbs. So I burned approx 10 lbs of pellets over 4 hours. From 3:45pm until 7:45 pm.

Breaking down the math, my original burner consumed (10lbs÷4hours=) 2.5 lbs per hour, with 500 degrees on my lid within the first 5-10 mins, and my internal mass finally getting "hot" around the 4 hour mark.

I'm guessing that's about the same economy as my stove would get burning regular wood also. However I think that the new jet style pellet burner will be even more efficient yet.

( ash build-up inside the first original vertical pellet burner was not good after 4 hours, too much build-up, one primary reason why I'm building the new one

The stainless seems fine after about 7-8 hours of burn time, and the rest of the steel seems fine after almost 40 hours burn time on the entire stove now. I only noticed a slight uniform warp in my thick 1/4" lid, but it looks cool if you even notice it, and I've been growing a liking toward this other thin grease barrel lid for some reason. It fits good and heats up fast, and no cold square corners.

I'm still learning, but I've come so far. This prototype has taught me a lot already.


More to come yet

It's quite nice in the flame path. IIRC, it kind of degrades after a while, if not ridgidized.

Rocket stove video #5 is live, and #6 should be live around 6pm EST.

These are both 10+ min long HiDef videos. Video 5 shows temp readings 10 mins after sub-zero start-up with my original pellet burner, and video 6 shows the first fire of my new jet-style pellet burner, and also temp measurements after 15 mins from sub zero start-up

I will edit and post the links after 6pm est, otherwise "Check My Youtube" below

I discuss the dutch oven in one of my previous posts/ videos. Have you seen them yet?

The one I wanted to use dissappeared, but its just a round charcoal BBQ lid with a temp gauge . I had a cool old coleman camp oven on there in the video temporarily, but its way out of shape and not right for what I want.

Imagine something simple and familliar, like this, with a temp gauge

I had a lid like this, which I planned on using, but I lost it. I need another for my simple removable dutch oven

I think a temp gauge should be on there. Like the stainless one. I have bbq lids, and I had a red round one like that, but I seem to have lost it. But you get the idea... That's what I want to do. Very simple, removable, and be able to read temps hopefully

I'm sorry Fstyles, my bad. I guess I completely forgot to post up the latest videos, which is where the brief dutch oven discussion is. I've been busy with work and life I thought I posted them up already.

Here's the latest links


Rocket stove #5 (original pellet burner temp readings early into a sub zero start-up, brief dutch oven discussion, show and tell)
https://youtube.com/watch?v=WVEP1sxA9ig#

Rocket stove #6 (new pellet burner temp readings early into a sub zero start-up, show and tell)
https://youtube.com/watch?v=GDX5gzR3dn4#

The steam-punk look is cool but I should paint this thing soon, I've contemplated using ceramic auto exhaust headder coat/paint. But stove paint is more common I guess and my temperatures are not ideal for painting right now, maybe in march, or if the stove was hot I might be able to paint it in my unheated shop...

Back 2 The Basics!

Today I burned some stick wood! Something different since I've been running pellets and such lately.

I made 2 more stainless liners, one for the feed tube and one for the burn chamber. They aren't perfectly snug or shaped, since they were round tubing and I crudely turned them into square tubing, but they are as close as "damn" is to swearing

Took more time to get there, but I had the same 610 F max reading on my laser gun after about 20 mins into a sub-zero start-up.

Yes everything is measured in Celcius here in canada. Its very simple because 0C is freezing point and 100C is boiling point. Easy.

However oven temps and americans use Farenheight. Yes my gun is rated for 315C max, which is around 600F. I've been reaching 608-610F before my gun maxes out with an ERR msg on the LCD screen.

Why is it rated for 600 but go up to 608-610 I don't know, but its goes higher than its rated for, and I can cook on 400-600, so that's all I need. I'm not worried too much about 8 degrees here or there. Although it would be nice to have a higher capacity/capabilites, this works well for this specific job.

They are 99.99 CDN, but they often come on sale for 39.99 - 69.99 at canadian tire. I think they have a newer fancier model out now.

How's everything else going Styles? Anything new or exciting going on in the hot water rocket industry?

FSyles- i cant check the link from this browser but i will check it out as soon as i can.

Good News! i have an electric BBQ lid coming tomorrow and i havent even seen it yet. i hope its the same as the stainless one i posted a photo of earlier. this means i can test and measure temps on my simple DUTCH OVEN CONCEPT. im excited for that! I should bake a pizza or something for the ultimate first test. or any reccommendations?

Any suggestions on fuel source? I'm thinking the good old stick wood. I got into this efficient rocket stuff specifically so I could burn wood from the land here. I love the pellets, but you have to buy them, and I prefer to live off the land...

youre going to need to plug those holes to keep the heat in. i know the tiniest little opening in my oven and i cant get it to 350 degrees. i forgot to mention that with my new improved heat riser insulation i can reach my desired 350F in my oven without the upgrade. i will still do the upgrade so its easier to get there.

i am a live off the land kinda guy also and think pellets are cheating and expensive compared to my own wood. i got 182 acres of wood to pull form and pellets cost way too much and add more steps of processing and a larger carbon footprint than what i do.
