Quoted from kungfucop:

I was originally gonna get some help welding the handle bar like Kneissl's mod but then changed direction and decided I'd like to have my bar be able to lock in place. I also didn't want to alter the original equipment or as little as possible. So here is my take on the HF lift table mod.
I bought a 1" diameter aluminum pipe and cut two pieces about 4 inches in length. Drilled a hole using a 3/8 drill bit only thru one side so I can mount it as factory.
Then I bought four 1" diameter aluminum flag pole bracket mounts with the serrated style teeth gear...similar to this one:

Separated them from the base and mated the pole mounts together so it can swivel or lock down with the wing nut with 13 variable angles. I had to grind down the teeth slightly so it would mate better since it was only supposed to be mated with the base (ie. teeth on the base side is concave and teeth on the pole mount side convex). Also cut the length on one side of the flag pole mount down a bit so that when the handle bar is folded down, it isn't resting super high.
Then just pop the mount onto the 1" pipes and insert original handle bar and tighten everything up. I did find there wasn't enough slack for the release cable even when adjusted to the max length so I'll need to make a slight extension. I may decide to paint the flag pole mounts later to match the lift table dolly but for now it works fine.
Doing it this way, I didn't need to alter the original lift or handle-bar and the mod is fully reversible.
Equipment
=======
1" aluminum pole - Home Depot
Flag pole bracket - locally from store that sells flag pole stuff or online. "Valley Forge" may be the brand you want if you are looking for the serrated teeth style. The ones I got are generic and made in China...LOL.
Two 1/4 washers for the wing nut side - Home Depot
Drill + Drill bits
Dremel with cutting wheel (or pipe cutter) and also small grinding wheel.
Adjustable wrench and socket set for loosening handle bar release cable thingy
