LOL! When you want to use AC you just push a button that pops a balloon that scares a chicken that a cat chases that generates static that gets combined with battery voltage that makes the clutch engage!!




As a side note to those wondering, i emailed a company that makes the batteries that are both 6v and 12v, they're based in hudson, OH. They say it's really two 6v batteries in a single case with a supplied parallel/series switch. It's supposed to be really just for 12v starting and switching back to 6v, and it specifically said i the quote that it's not for use with 12V accessories. Also, the price tag was between 2 and 3 hundred depending on size and shape of battery. Interesting info for those out there curious.



Most of these options defeat the idea of quick and dirty and simple (although designing systems on this thread with tons of converters and work arounds and work arounds for problems for the work arounds has been fun).




Here is my conclusion:
We have been tying up turbo's time so that speedster isn't getting done any sooner, so we gotta let him get back to work.

I'm feeling that if you're running a 6V system and refuse to convert, you have to run an AC system like it would have been ran before cycling or on/off clutches came into play.

Combine that with parts that are readily available and cheap and i think we're looking at a constant on compressor with some type of throttling device, and that points me to early-late sixties GM. (and 80's, but i hear the R4 compressor i have has a terrible reputation, and it wouldn't even look CLOSE to old fashioned)

When i mount the 327 on the stand i'll look at mounting an A6 compressor somewhere and driving it likely on the water pump with a pulley behind and tensioning it like an alternator with an adjustable arm (unless there's a reason i haven't thought of why i HAVE to have an idler, i'm sure there is and you guys will let me know)

From there it's about finding a condenser and evaporator and going with suction throttling of some sort (choose a type with a receiver/dryer OR using the VIR setup (looks too new under the hood but could be disguised or hidden).

From there i'd use a blower fan for the AC only and a duct into the cabin and be done with it. No mixing of climate control, etc.


I feel that this design meets my needs and goals, and is still old fashion and not TOO comfortable. If i wanted to go modern, i'd make a street rod out of it and convert suspension and motor and everything. This should still be somewhat "rustic" and look acceptable for the period, and still feel old fashioned and yet have something that many period cars don't have so it will stand out.


Alternatively, if anyone out there wants to try this, you can decide to get the 5amp step up converter and see if you can get it to hold your clutch closed. If so, you can have it setup so you only have the compressor on when the AC is on or use the VIR setup to cycle the clutch and do more fancy things that i'm not too interested in.


Once i get pictures and get started, i'll update everyone here and see if the system works, trouble run into, shortcomings, etc.

Thank you all for the input and help, and i'll be checking back for/with further discussion.
