I utilized Larry's drawing regarding the collar around the front gear
torque tube and it worked out perfect.
The only change that I did was chamfer flat the area's opposite the head
of the through bolt that tightens
the clamping action on the torque tube and then put a nut on the thru
bolt instead of threading one side of
the compression rings. The critical measurement (2.002") is the
completed center I.D. of the completed
clamp. It fit the torque tube like a glove without compressing the
torque tube one little bit. I made the
exterior dia. a 1/4" larger than Larry's design which gives me more
material for the through bolt. It
also will now work with a Cessna 150 tow bar without any modification.
The 150 tow bar is easy to
find.
This is an excellent design for eleveating paint scratched off the front
tire faring by putting a a tow bar
against it and also the safety factor of stopping the complete
compression of the torque tube if the
bungee broke by some type of circumstance.
It took me about 2 hours on the lathe and maybe $.50 worth of cold roll
steel bar to build it.
Excellent design Larry - I take my hat off to you.

Jay,
Better than putting a tow bar at the axle, you should consider using a
travel stop and tow bar ring a few inches below the firewall
mounted on the strut. Then use a tow bar on the ring to pull the plane
from a better leverage point for steering.
Also, if your bungee lets go, the travel stop ring will keep your prop
out of the dirt.
On my site, I've free drawings available for making the ring and the tow
bar, or you can order the finished product.

On the Spruce & Wick's web sites, I see lots of tow bars. No specs. Does anyone know what specific model of tow bar will work with the 60XL nose gear axle?
