It's slightly cheaper from Online Metals. It looks ridiculously cheap, but they kill you on shipping. $40 shipped vs. Amazon's $50 shipped:

Amazon wants $44 + $6 shipping

Vaseline boils at 260 C, and has a flash point of 205 C.
I don't think that will be a suitable filler.
As for the thermite (ignoring whether or not you'll be able to get a proper composition), United Nuclear puts ignition temperature for thermite at 1650 C, however that (could?) change with composition. Thermite also requires two different metals, if you insist on using scaps and grinding them up (probably a waste of time for the savings), just use copper for the highest thermal conductivity, and peace of mind. Otherwise just buy some, it's cheap.
I'm exploring the idea of making a DIY Brew Jacket. It appears to just be a peltier thermal cooler with a heatsync and fan, and a rod that submerges into the wort. And of course a temperature controller. $200 is way overpriced, I think it would be under $50 DIY.
The only tricky part is attaching the rod between the heatsync and the peltier device. I'm thinking a copper rod like this would work, but I have no idea how I would couple it to the rest of the setup. Any ideas?
I checked Amazon, found many copper sheets, not sure what size you need tho!
https://www.amazon.com/Copper-Sheet-Metal-12/dp/B00AKMNNX4 there are some options
110 Copper Sheet, Unpolished (Mill) Finish, Standard Tolerance, Inch, ASTM B152 http://www.amazon.com/dp/B00CNLWRZ0/ref=cm_sw_r_udp_awd_LDC4tb128FZ1B
Here's a 12"x12" sheet that is a little bit thinner than a penny:

Cutting out a box pattern with tabs to join the seams would provide enough structural integrity. Making the lid might be a bit of a trick though.
Getting a better piece of metal and method of securing it would be awesome. However, I don't have the tools to cut thin sheet copper, nor would I want to spend a hundred dollars on a custom cut piece.
A quick google search brings me to this saw. This would be totally feasable, as I've cut thin metal this way before when I was in middle school. Now I just need to find some thin copper sheet.
I never considered option until now. Thanks!
EDIT: This sheet seems to be a possibility. I need to do some more precise measurements.

Copper. A few challenges but the best cooling, especially for a tiny form factor with poor air cooling potential.

It's this
edit: sorry, just posting the link was a bit abrupt. Specs claim 110 copper, 1/8 hard temper, Standard tolerance, .064" thick. That seems a little thick for a utility knife to me.

That or the CFO has a Escalade ext, maybe i should just swap windows...
Yes. More of this!
[Edit] Sticking with the stick theme, how about some divining rods??

I used this. It doesn't look like the picture. It's solid - not stranded. It's ridiculously difficult to bend into a pleasing shape, but it doesn't have to be perfect. It's not HARD to bend, it just has a mind of its own.
85 MHz corresponds to channel 6. FM radio starts at 88 MHz and may be a problem. I don't have any experience with FM filters, but that might be something to think about.
You'll also need a balun and some way to connect the two. Solder is probably the normal method. I couldn't find a connector to mechanically join this relatively wide wire to screw posts for a balun. Maybe someone has one? Smaller wire can use something like this plus a female/female adapter?
