Today was ground buss day..... Had planned on making up 5 ground cables - but realized I could only finish two and get the third one started without the fenders and grill in place. Was going to run a ground cable from battery to a stud on the firewall (that stud is a threaded brass 1/4-20 machine screw with the head cut off). The stud actually will be one of two that attaches 2 copper ground blocks to the firewall, one inside and one outside. Each block has several holes threaded for #10 pan head screws. I figure this way I can attach small gauge wire ring lugs or larger ring lugs to the threaded studs. Now, before I start with the pics, you need to remember I told you early on I'm a cheap bastard, and that combined with my willingness to do whatever I think will work means some of this may possibly be classified as stupid........ If so, I'm SURE someone will let me know LOL.
My ground "buss" is actually from an old pair of jumper cables my neighbor was getting ready to throw away. The clamps were very rusty, but all I needed was the wire itself. They were nasty, dirty, and stained, so they look anything but clean, but they should do their job nicely. Then a quick trip to Northern Tool and I had some stuff to start working.
The big surprise is they had marine grade shrink wrap in stock - who knew?
To get the crimping done, I refused to lay out the funds for a really nice crimping tool since I don't plan on doing this much, ever, if I can help it, so I made one. I was quite proud of my self - Took a hex bolt that the back of the ring lug would just fit into, and drilled a hole so I could use a punch and mechanically lock the wire in place prior to soldering.
Then it occurred to me I'm an idiot - using that on the second ring lug would mean the crimping "tool" would become a permanent part of the cable..... So I just cut the nut in half and still used to punch to lock the wires in place. I also drilled a hole in the ring lug to use as a solder inlet - the cable insulation came up almost to the rear of the lug, And it worked nicely.
Here's a shot of the cables that ground the heads and block - after getting the fenders and grill in place, I'll get the grill ground pad in place as well as the cable to the right head.
The threads in the holes used for ground were chased with a tap, cleaned with lacquer thinner, as well as the bolts, and then a helping of copper anti-seize was applied:
Here are both cables on the back of the engine.......
The main point today was to get the stuff done that the tub would have complicated had it been in place. Translated - I wanted to get the rear ground pad installed and wired. Here it is after the install - large brass screw for mounting, small stainless machine screw to prevent pad from turning.
Here's and underside shot. In the event I need a threaded stud for some reason, I have one back here now.... And it should be relatively easy to attach ring lugs to the block after everything is in place.......
I think for the ground cable - rather than clip it to the frame rail like the brake lines, I think I'm going to run it forward thru the right frame rail. Sounds reasonable in my head - Anyone see a problem with that idea? If not, I've only got a little very light surface rust to deal with on the bottom of the tub where the body mounts were, then it's time to stick the tub back on the frame
