Some time ago, I visited a web page that described an oxalic evaporator heated with a jetta igniter. But I've lost the URL. Can anyone help me?
I disassembled one of the store bought ones and took some pics
I changed this to point to some pics of the one I built
the last pic is a couple that I built
the "action" end of it is just a diesel glowplug

How does it work?
How did it work?
I been thinking that you could rig a 12v ciggarette lighter element up...
it works great
the nice thing is you can plug it in and walk away and protect yourself from the fumes
check this one out
I would think a cig lighter would work
you just need to get the element in contact with the pan holding the acid
Is your mounting bracket(glow plug holder)& pan aluminum?
Did you router out the pan?
Did you tap the mounting bracket so the glow plug screws in?
Does the acid pan connect to the tip of the glow plug with the set screw I see on the side of the pan?
Real nice job,BTW
Would you consider selling me one? I'm serious.
I consider it 3 parts
the "base" or maybe the heat shield, which is the sheet metal pan it sits on
the "block", which is the thingy that holds the glow plug
and the "evaporator dish", which is what holds the acid
(and maybe the handle which could actually be a stick)
the store bought job uses aluminium for the "base" which I've heard critisised for being "flimsy"
I used galvanized steel cause it's what I had
the other parts I used a milling machine to make
I had to choke up $5 to get the fancy metric tap so the glowplug would screw into it
the trick is to build it such that the evaporator pan is suspended a little above the "base" so as the prevent heat transfer
probably a trivial delail, but a nice touch
anyway, I only built 5 and I already gave a couple away, if I build some more I'll let you know
Using a diesel igniter is a neat idea. I'd promised to work on an 12V oxalic evaporator. Researched cartridge heaters and bought a halogen bulb. That's as far as I've gotten. But there's no need. You guys have done a great job.
I'll link to your photos and the webpage. And I can finish off my oxalic page.
I've always liked the idea of an 12V electric evaporator. From a fire hazard and exposure aspect, they should work alot better than the old propane torch. But most have the same limitations when trying to use them with my migratory bottom boards.

But it's not un-doable, you only need to pry the opening up a little and insert a block while the unit is in there. The block also helps while you are inserting the foam strip to hold the gas in. And the wedge crack in the side can be duct taped, and that tape used over and over again.
