Another ultimate stove base possibility

[Moondog55]

I think I may have found an Ultimate Stove Base for cooking on snow.
We had a problem with the induction range and one of the elements has been replaced. Also replaced was the two part thermal insulation pad. One section is a very high temperature ceramic fibre pad and the other is a foil and fibre RFL disc.
I'm now looking for something ultra light to layer under the ceramic fibre and I'll silicone them together.
298mm in diametre
The ceramic fibre is quite fragile so it will need the the protection of something. Cardboard would work in the short term but I'm thinking 4mm Hardwood ply if I can find a scrap or maybe a piece of thick aluminium foil like BBQ wrap/
Very light and my scales don't have a memory function but probably less than 40 grams
Mainly for use under a blowtorch like stove like the MSR Expedition for snow melting using big pans. My own dedicated snow melting pan is the GSI 5 litre which is 255mm in diametre and I've been using a foil topped square piece of plywood much smaller with one of the cheap folding windscreens

Interesting.
What is the diameter that you will need?

 

[Moondog55]

I think 300mm /a foot. If a windscreen that is that same diametre then there would be just a ~20mm gap between the pot and the windscreen.
For melting snow I usually use [ or try and use] a windscreen as tall as the top of the pot rather than the short one supplied by MSR, I use offcuts of HD aluminium flashing usually but my folding windscreen is about 250mm tall.
Maybe it is as much about peace of mind as much as stability, although they do go hand in hand; you can relax with a stable pot and not need to be watching it constantly, in fear of it toppling over. Maybe I should experiment with some thick Kraft paper and BBQ foil, it will be at no great cost

Yes, craft poster board like what is shown in this video. Use 2 pieces. Turn one of the pieces so that the grain is at a 90 degree angle to the other to prevent warping. That will make it much more rigid. The video will show how to determine the direction of the grain.

Did you try making one with the craft board, 2 pcs.?

 

[Moondog55]

Not yet. Doing Grand-Pa duty with a 17YO Femme here and things get hectic with the new chickens as well
Ditto moving gear from the shed to the new utility trailer

Ok Grandpa ....,.

I'm going to make one and see how it works.

 

[Moondog55]

You got me motivated.
The Boss is off to a KaffeeKlatsch with old work colleagues so I got into it. Kraft paper verboten as my wife uses it to make patterns but the thin packing card is probably stiffer and not much heavier. Glue should be set before she gets home and finds me glueing stuff on her fabric cutting board, Hence the protective plastic. Old credit cards/membership cards make good glue spreaders. Water won't be wasted as I'll be making stock later today

I cut 2 pcs poster board(craft paper )12"
Spray glued them together. Will let them sit overnight on flat table to dry.

 

[zelph]

Hurry, clean up before boss gets home

Mine weighs 45 grams in the square mode. Tomorrow I'll cut it into 12" disc

 

[Moondog55]

Two layers of cardboard, foil and glue 90 grams.

Now waiting on silicone to set; that will take at least 24 hours.
EDIT
Actually now set
174 grams
