Tube clamp for hi-lift jack

(1/1)

kvom:
I have been looking for a good solution for mounting a Hi-lift auto jack on my Jeep.  Since the rear frame is made of steel tube, I decided to make a pair of tubing clamps, similar to what I have seen commercially.  The main difference is that these cost me less than $5 for fasteners, vs. $60 for a store-bought pair.

The first step was to cut a 1.75" slice from a length of 3" diameter aluminum rod.  I then faced, turned, and bored the piece on the lathe, then parted off into two .75" thick rings.  Since the tubing I will be placing these on is 1.75" diameter, I bored the holes .05" oversize.



The rest of the operations were milling.  The finished result looks like this:



While the work is conceptually pretty simple, making a pair of these took the best part of 5 hours.  Mounted on the Jeep's rear frame, here's one of the clamps:



The central  mouting bolt is 1/2-13, while the two clamping bolts are 1/4-20.

May of cost only five, but making them yourself "Priceless".

Agreed!  And what better way to spend an afternoon with outside termperatures over 90F than in a shop with AC?   :beer:
