I'm just going to throw up a few pictures of a pair of Farmer's Walk handles I built from off-the-shelf parts from the hardware store. I'd seen several designs that required drilling through the steel, and I really didn't have the bits, the clamps, or the time to do that, so I came up with another option.
Only needs an adjustable wrench and a screwdriver to assemble.
As far as the pipe, the place that sells the pipe can/will usually cut it down to size for free. In the midwest, I could buy 10' of 2" pipe at Lowe's/Home Depot/Menards, but on the west coast I had to ask around and get it from a plumbing supply place in town.
Assembly should be pretty obvious from the photos. The only thing to take note of is that there's two washers and a nut on the underside of the handle, just to keep it from slipping down the bolts.
Basic parts list:
- 2x 5' to 6' long pieces of 1-1/2" inner diameter Schedule-40 pipe (roughly 1.9" outside diameter). Mine are right around 5'6 apiece.
- 4x 3/4" diameter black pipe T's
- 2x 12" long, 3/4" diameter black pipe nipple
- 8x hinged pipe hangers (see pics)
- 4x long bolts that screw into the pipe hangers
- 8x large washers to go around the bolt and next to the Ts
- 4x small washers to transition between the large washers and the nuts
- 4x nuts to hold the handles on at the end of the bolts
- 4x vise-clamp style collars to keep the plates from sliding off the end
Vise-clamp style collars need to be clamped down hard to keep the plates from sliding off the end if they get dropped hard
The bolts should be long enough so that he handle can be used to keep it from rolling away
I may update this with better measurements.
