John,
Would it be possible for you to give us the details of the handle you used and how the assembly was put together?
Many thanks, and assembly you designed looks real good.

You've probably seem Adjustable Handles before but they what makes them useful is you can pull up on the base of the handle and it rotates free from the stud (or nut) to allow you to reposition it to apply more turns. When you pull up on it, you are lifting against a spring. The repositioning of the handle allows you to turn the screw eventhough it next to an obstruction or wall. Like nuts and bolts there's a whole assortment of different threads, lengths, handle styles and materials. I used a stud handle for the house batteries McMaster-Carr (http://www.mcmaster.com/#6320k72/=az6avo) but you should measure the fastener(thread and length) that's on you battery setup to match to it. I made a locking nut by taking a scrap piece (don't pay attention to the strange shape) of aluminum (happends to be black anodized) and drilled and tapped a hole. The long side of "nut" rests against the battery top such that the nut wont spin when I try to loosen it in a hurry.
I did the start battery connection a little different using a female handle McMaster-Carr (http://www.mcmaster.com/#6320k57/=az63o2) on the standard battery post square head screw. I think I was in a hurry and told myself I would make up a locking washer to prevent the screw from turning and never got around to it - you know how that goes. So far every time I loosen it the screw never turns. Here's some pics:
John,
Thanks for going out there in this freekin' cold & taking the pictures. It is crystal clear now. The only real challenge for me is fabricating the aluminum piece for the house batteries. I do prefer to disconnect the batties' cables as opposed to using the typical permanent mount "quick disconnects" available. The appropriate rated quick disconnects are very pricey indeed.
Just occured to me you could use a 2nd Adjustable handle to replace the aluminum piece - one male, one female.
I understand your concern about additional connections but properly done and protected by something like Corrosion X a properly sized switch should be just fine. Here is such a switch rated at 2,750 amps for 10 seconds and 1,325 amps for one minute.
