Title: Any ideas for a better way to attach my electrical connections
Post by: passingtime38 on June 11, 2008, 12:26:34 AM
My plates are an 1/8 inch thick and very close together.  i'm placing them - ++ - - ++ -  I have 5 leads.  On the outside of the neg, between the pos, between the neg, between the pos, outside the neg.  I'm using nylon bolts and stainless washers to press the leads together.  I don't like the way I'm doing it very much, but the distance between the plates is basically one stainless washer.  Does anyone know of a good way to connect the leads while keeping the spacing very close.  Thanks  R.

It sounds ok. If the bolts are off-set, why not use ss bolts? You're not using ss washers between + and -, right? Post a pic!

no + and +   I can post a pic tomorrow it is out in the shop.  Stainless steel bolt would cause a short across positive and negative.  If the nylon bolt loosened, then the connection would slip and that could be dangerous.   :'(

That's why I said the bolts should be off-set.

Depending on your bolt pattern (where the bolt holes are located on the plate), you could rotate all of the + plates 90 degrees, use ss bolts connecting all plates of each polarity, (passing over plates of the opposite polarity) and a nylon bolt (two would hold better) near the center of all plates.

Or, you could do like here, http://www.youtube.com/watch?v=dNL0alFIliQ  and cut off opposite ears.

Let us know when you post the pics!

I watched the link.  How can I post a you tube link.  I've tried the dog ear style but I don't like giving up surface area.  Can I post a video of my progress right to this site?  my bolts go through the top and bottom.  my latest youtube video is a volume test.  I have the same user name there.  But i'm trying different plates this week.  I only got 400 ml.

I was watching your tube vid.  Has anyone mentioned using zip ties to hold your plaets together.  I like drilling small holes using nylon washers from a hard ware store for spacers and zip ties.  I'm going to try   thin strips of tap next.

Is this a Boyce cell? If so you could make new power plates cut them so there's a tab on them. 1/8th inch is really close and filling some of it could cause trouble. Sorry didn't find the link for the video.

Yeah... seeing it on video helped me see and think through some of my probs. with the setup I had. I did the zip-tie and nylon washer thing when I switched to the ss welding rod for power cable. I got much better results, but also a near doubling in current draw. I'm now looking into using fewer, larger plates. Have also pondered arranging the plates in opposing fashion (like a capital E and 3), offset to mesh, so I can use a large flat strap on each (+ and -) side for a better connection and better stability for the plates. You are using really thich plates so the tape idea should be ok- watch and check, now and then, for friction wear if you put it in a car. My plates will be of .01" material and I'm concerned about mid-plate contact with jostling. Cheers!
