Based on my earlier waffling about making an Ergo-style handle, here it is.
First I used some stiff wire to bend up a suitable shape, based on the various photos on the Ergo handle website. This gave me an idea of the final shape. I used 1/2" steel rod which I heated in the forge to help bend it. It was a bit hit-or-miss trying to get the angles correct and took a bit of fiddling to get it right (I made a second one at the same time, but I'm not happy with one of the bends and will have to re-do it). I don't have a suitable bender for this size rod, otherwise I would have bent it cold which would have given me better control in getting the angles right.
I cleaned off the firescale with an angle grinder and Parkerized it, finishing off by rubbing on a wax mix while it was hot.
I went through a few ideas about the handle and finally settled on a piece of hard nylon rod I had, 1" diameter, and bored a 1/2" hole through it then slid on a piece of Hypalon grip that I had left over from my fishing rod building days. I'd already drilled and tapped the end of the steel for a 1/4" Whitworth thread and put a couple of suitable washers on the end, held on with a metal thread screw to stop the handle coming off. The other end of the handle butts up against a washer that I had earlier welded onto the steel handle. The handle rotates easily and has a nice comfortable feel to it. Now it just remains to be seen how well it will work, but when the handle is pulled down it stops 8" above where the normal handle stops.

Sorry about the photos, the sun was coming through the window making it a bit glarey!
