Step 1: Folding Step Stool

Picture of Folding Step Stool
Needing a kayak cart, I was looking for alternatives to measuring / cutting / gluing (cursing*&$#! / re-measuring / re-cutting / re-gluing) a PVC cart.  In the process, I came across this folding step stool.  (ranging in price from $10 - $15 online or local store)

Step 2: Axle

Cut a 3/8" threaded rod to 17" in length - grab a few nuts and washers along with a couple of 8" wheels.

Step 3: Drill

Step 4: Insert Axle

Slide the threaded rod through the hinge and center it.

Step 5: Lock In Axle

A washer on either side of the step, double nut to lock in place (it also gives proper spacing/clearance for the wheels).

Step 6: Add Wheels

A washer on either side of the wheel and another double nut set on the outside (end cap optional).

Thanks so much! Built one this weekend and it works great. Found the stool and a pair of 7" wheels at Kmart, got all the hardware at Lowes. Cost all together around $25 to complete.
I'm going to use this idea. Me and my boys are going to build a canoe this summer. I'll use this for that thank you

That's a pretty good idea. I like it a lot. The only thing that I would change would be to swap out the threaded rod with a solid rod that I tapped the ends on for the bolts. It would eliminate the need for a second set of nuts to lock the first and be much stronger.

By the way, what is the load rating on the stool that you purchased?

The step I found at Kmart looks to be identical to the one found on Amazon (Kikkerland Rhino Easy Fold Step Stool). Rated up to 300 lbs.
