This is the start of the plate that ill bolt the back of my jeep along with the overhead rack. the bolts are 5/8 so i have punched and drilled smaller holes to guyed the lager bit.
Here i have the insulator for the top mount. not complete a this point as it will have flat stock
welded the toe back so i can bolt it to the rack
Stainless steel 5/8 bolt i faced in the lathe, the taped it for the screw
The insulators i turned in the lathe. They are made out of cutting board plastic because this
is all i had.
As a side note this is not the best plastic to use for out doors because it will brake down in the weather. Delrin is what is used most of the time for this, and i have some on order now to replace them soon
This bolt i reused form a heavy duty cb antenna mount i broke some time back. the top is 3/8x24 and the bottom is threaded for the 5/8 bolt.
All put together on the mount
Top insulator made out of the same cutting board plastic
the other side
Mounted to the truck with the coax and grounding strap to the frame. ill be adding a cover to this to keep mud and dirt off of it.
