12 volt oxalic acid vaporizer
« on: November 04, 2008, 02:00:39 PM »
Has anyone built there own?  If so what glow plug did you use.  I went to Napa and there are so many to choose from.  I printed the pictures from
http://www.drobbins.net/bee's/oa_evaporator/  but only have a screwdriver in the last photo to estimate the size.

If I remember correctly, it is from a late 80s VW Rabbit and it was ~$20 at Napa.   It has been a while since I tried to make them.  I couldn't find anyone to machine the cup for me at a reasonable price, so I gave up.  I can take a look at home to see if I still have it written down.
BTW.... I'm referring the the glow plug used in the JB200,  not the one shown in your pictures.

Yes, it is made from aluminum.   Unfortunately I lost my JB200 2 year ago.  I don't know if it fell out of my truck or what,  but I last used it 11/06 and haven't been able to find it since.   The cup was not that big,  maybe 1 x 1.75 x .5...

Your about 2 months too late in asking.   I had made a complete set of .dxf files when I was trying to find someone to cnc the parts for me,  but they where on an old laptop that I just recently got rid of. :roll:

Maybe I should just buy one for 85.00 bucks and then make some copies.
