titanium heat exchanger help

you need a series of test runs that validate the results … not just a single one

yeah its more work =P

agreed, I've got several part used canisters floating around I need to find

Seems quite realistic to me.

> (not sure why those aren't the same or closer???)
No reason why they should be the same.

Roger- thanks- that's good to know, was hoping you were going to comment :)

borrowing from Kevin’s squeezebox design- I’ve come up w/ another exchanger- folds are at the 1″ mark, weight went from 1.4 to 2.0- so no too much more

as of yet untested

Drill a small hole through each fold

Run a wire all the way around and tighten so there is a friction fit between heat exchanger and pot

Then there would be more heat transfered

jerry- I'm not following you w/ the wire, the "exchanger" is fit via friction (it's pretty tight actually)- a wire isn't going to make it much (if any) tighter or does the wire serve another purpose ie connecting each and every fin to make it more efficient?

Picture being worth 1000 words:

The MSR heat exchanger has a strip of metal with some screw device to tighten around your pot. A length of wire would be easier and lighter and still do the job (maybe).

jerry- that's similar (bit lighter) than what MSR does w/ theirs, mine however has a simple fold over bit on each end- the "exchanger" is very tightly fit to the pot- I can shack it vigorously and it's not going anywhere- which makes it lighter yet :)
