I've been re wiring my tractor & needed a couple of clamps. It's been raining hard all day. I had my ipod playing bluegrass, plenty of coffee, & things were going great so I didn't want to leave the garage. This is what I came up with.
I cut a piece of plumbers strap 3 3/8" long & a piece of 1/2" diameter heat shrink tubing 1 3/4" long. Most of this strap is cut the same but you may have to make a few adjustments in the length. I also drilled out the 4th large hole a 1/4" with a step drill. This will meet up with the top hole for the bolt. Make a 90 degree bend between the top large hole & the small hole as indicated.
Slide the tubing as shown.
Hold the top bend area against a 1/2" rod or what ever you have then wrap tightly around the rod. If all goes well the two 1/4" holes should line up. Once this is done shrink the tubing. I rounded off the corners to give it a professional look
The first clamp I used I needed it where an engine shroud bolt was very hard to put in earlier because of lining up the sheet metal. I didn't want to back it all the way out so I clipped off the area between the holes so I could just slide it into place. Hope this comes in handy for someone & thanks for looking.
