My “modification” is hardly any big deal, but it might prove helpful
to someone. Because of arthritis in my hands I had a problem with the
several knobs used for tightening. These knobs were replaced with
Allen cap bolts.
I use one of two sizes of long-arm Allen wrenches, allowing me to
push or pull to tighten and loosen. The larger of the two Allen
wrenches had to itself be modified by shortening the short arm of the
wrench for clearance.
The wrenches are held for storage against the body of the tool with
Only here in the last few days I have put several layers of RUBBER
electrical tape on the long, or “handle” part of the wrenches, to
make the push and pull even a bit easier on the joints.
GRS was great. I called them to tell them of my problem, and ask if
they had alternative knobs, or something, to make tightening the tool
They didn’t, BUT one of their support people (engineer?) came up
with the Allen wrench adaptation, cut the bolts to the right length
for the tool, and sent them to me complete with the wrenches, and
directions of installing them. I could have gotten the bolts, cut
them, etc, but they cheerfully did it for me, and sent me the parts
FREE! I modified the wrench myself.
Not much of a modification, but one I have really enjoyed.
