Quoted from Vitty:
Could you shoot me the parts you used to get your handle to do that? I've got the same cart and have been investigating how to more effectively use the handle without just taking it out and dragging it along
Get a pipe cutter from the hardware store for making the cuts - MUCH easier/cheaper than a hacksaw and under $10.
Aside from that here's the parts list copied from the HF thread.
4- Eye End Bimini Top Cap/ 1'' inner diameter/ Marine Stainless Steel (make sure these are 1 inch inner diameter)
2 - 1/4"-20 Hex Bolt
2 - 1/4"-20 Stop Nut
4 - 1/4" flat washer
4 - 1/4" flat washer nylon (make sure they are nylon, NOT RUBBER)
I got the 4 bimini caps on ebay for 26 total. You can find them on amazon and some marine supply shops as well. Unfortunately...Home Depot and Lowe's don't seem to carry them (at least, not any near me...and I live on a Lake. You would think they would have more "marine" supplies).
I got all the nuts, bolts, and washers for 2.08 at Lowe's. That means this mod is under 30 bucks. Im sure you could go cheaper...but go ahead and get good quality items. It is worth the 30 bucks.
Measure and mark 3.5 inches from the bottom of the handles with a sharpie (1 cut per handle. Use a hacksaw. You could go as little as 3 inches...but after testing repeatedly...3.5 inches is truly the sweet spot for handle usage and fold-down storage.) Cut the pieces.
Screw in bottom pieces (with the holes) with a 9/16 wrench.
Set up the bimini caps in the following pattern (pictured below as well):
Bolt, flat washer, nylon washer, bimini cap, nylon washer, bimini cap, washer, nut. Tighten with 1/4 wrench.
Connect bimini cap elbow mod onto top and bottom using the allen wrench. Make sure to face both bimini elbow joints the same way (as pictured), so they will fit. I also recommend connecting both bolt/nut setups in the same direction.
