Needed a 6 sided megawrench for a 4 inch pipe cap. Stores were closed (and I doubt they would have one anyway). Decided to make one.
It's made from 1.8mm (5/64") roof tile straps. 2 pieces 4" long on each side. The last side has a 6mm thick piece where a handle could be welded (I used a 3/4 drive socket from an old extension. You could use a horizontal pipe fitting or piece of pipe as a place to attach a handle.).
I tack welded using 2 mm rod at 30 amps (yes, that is too high, but I could not afford to have the rod stick). Finished off the corners with 2.6 mm (1/8") rod at 35 amps.
The rules of engagement on this job were:
1) Could not take all day
2) Stores were closed so I had to use what I had
3) Could not damage the plastic end cap. It was a special order, cost a lot and the stores were closed anyway.
This technique could be used to make much bigger wrenches / spanners for things like pipe caps.
- 1.8mm (5/64 inch) steel flat stock. For this wrench they were cut to 4 inches (10 cms) and excess cut off after tack welding.
- 6 mm steel (T shaped to hold handle mount)
- Square drove end from ratchet extension (the extension is the "point" on my post hole auger). This can also be a piece of pipe mounted to insert a bar handle or such.
