[quote]Back to 6v blower motros and AC clutches for a momment:

Someone mentioned shimming a 12v AC clutch to allow 6v operation. That mite be an excellent work-around, i don't know. IIRC there is an 'air gap' specified for AC clutches that the shimming mite compromise and thus compromise some other functionality of the clutch. More research would be needed.

HOWEVER, with all of the various jerry rigging discussed over the years noone that i can remeber has ever brought up the possibility of rewinding the clutch coil for 6v windings. Ditto for the blower motors.[quote]


Keep those options on the back burner for now. A 6 volt compressor clutch source is apparently still a myth but I'm not finished with the search yet.

On the blower motors. Fasco Motor responded and informed me that they are no longer supplying the 6 volt DC dual shaft motors that I inquired about but provided me with a contact in Canada that may be able to help. I will make that contact at first opportunity.

Meanwhile, I found these folks:http://www.dcm-mfg.com/pages/about.php

They list 6 volt DC dual shaft and single shaft heater/blower motors on the site but the response I got back when I inquired was rather interesting. Evidently they do not stock them but will manufacture them if the demand is there. The guys name is Fred and I explained to him that he was in a position to be the sole source provider and that he would have the market sewn up. This is his response.

Hi Gary, we currently supply some 6 volt axial radiator fans to a couple of customers. I'm sure we could supply a 6 volt dual shaft motor. If we were to do so, I would want to know the following:

1. How many per year could I sell?
2. target retail price?
3. multiple speeds?
4. single speed a non-starter?
5. overall length from shaft end to shaft end
6. max amp draw from blower motor allowed, with headlights and other draw on the generator.

Thanks,
Fred.

I told him I didn't have most of the answers but that these motors didn't vary a whole lot from around 1940 to 1955 and that he could probably satisfy the needs of just about every make of car from this era with one universal dual shaft and one universal single shaft motor as long as the shaft diameters were at least 1/4" and were long enough that they could be "cut to fit". I also told him they needed to be multiple 2 or 3 speed motors.
