I’ve written the “how to make a swivel hitch” in case some riders that have asked wish to copy.

I used a 6’ piece of 2”x2”x1/8” steel square tubing to make the tongue. I Cut off a 6”” piece for the front of the swivel piece, joining to the hitch. I purchased a 1 1/8”” lift pin from Rural King. You will need to remove the plastic coating and cut off the handle. Next grind down the pin head so it will slide into the 2x2 tongue with out rubbing on the inside walls. Next purchase 4 collar’s to fit a 1 1/8 pin, plus 2 sleeves to slide on the pin. The collars have Allen screws to lock them on the pin witch I removed. I made a template for the 2 collars threads to keep them aligned with the sleeve between them and spot welded them up. Now the “dog bone” created from the collars and sleeves welded. I next set the “ dog bone” along the outside of the square tubing, keeping the one collar flush with the end of the tubing. I marked the holes from the collars to the tubing and drilled corresponding holes in the center of the tubing. Make sure the collar is flush with the end.
Using 1” long bolts, I bolted the collars inside the square tube of the trailer tongue. MAKING SURE THE BOLTS USING A LOCK NUT DON’T COME DOWN TO FAR TO RESTRICT THE PIN FROM ROTATING. Bolted the other “dog bone” using the same procedure (holes aligned and flush drilled for the hitch side. I used a flat aluminum spacer as a shim to go between the front hitch and trailer tongue. Now the ends of the front and rear halves I cut a square piece of steel to weld as end caps to the Two pieces. Before I welded them up I drilled using a step bit a 1 1/8 hole centered on the caps.
Pushing the pin from the back end of the trailer side of the tongue, I guided the pin through the square tube and collars and out the cap. What I did too was drill a 1/4 inch hole in the tubing to install a trough pin past the pin head so it wouldn’t slide back out.
The hitch side of the tubing is basically built the same way as the trailer side. Measure the “dog bone” Make sure your collar is flush to the end too. Remove the Allen screws.
Using a square piece of steel and drilling a 1 1/8” hole I welded the “cap to the hitch side too. On the hitch side the “dog bone” does not need not be bolted down the way the trailer side was. If all went right the tapered side will come out past the hitch collar. I drilled a 1/4” hole through that square tube used a long bolt and passed it through the tube, pin and hitch to lock it in.
The pin can’t slide back or forwards . I used an eye bolt to lock the pin on the hitch side and clip the chains to it too.
Pictures to follow, they might not be in the properly sequence. Any questions just ask.
