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.

thanks rob
can you also give me the inside cup dimentions and I assume it is made of aluminum

Robo · November 04, 2008, 04:15:25 PM

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:

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