Content-Type: text/plain; charset="us-ascii"; format=flowed
Some time last winter I was dismayed to find that the port-side roof strut
had begun poking a hole in the top. I didn't analyze it, though, and it
still has a jury-rigged <g> backing pad to distribute the load.
Lately I've lost a lot of upper-body strength -- the top was becoming a
real nuisance to raise.
Few weeks ago I was raising or lowering it, and a nasty sharp twisted bit
of metal fell into my hand from the left-side hinge. That really made me
look, and I immediately saw that the hinge was trying to escape from the
joint, and had almost succeeded! Argh.
Results: That big fat inch-wide hinge isn't, it's a fraud, just there to
carry the spring cable and give it a fulcrum! The actual pivot has a
bearing surface about a quarter-inch wide, which bears on the piece of pipe
that forms the operating yoke of the H-frame -- the crossbar. With a good
deal of effort I cut the pipe, supported the joint and worked the stub of
pipe out. Fairly shocking, it was worn almost through, looked like someone
had been at it with a skinny dado blade. I made a substitute from a piece
of "bronze" propeller shaft, turned grooves on the plug end and epoxied it
into the cut-off pipe. Interesting keeping the grease on one side of the
join, and the epoxy on the other...but I did.
Final result: turns out I hadn't lost my strength after all. The top is
smooth and easy to work, and based on the pipe lasting 20 years, the bronze
ought to be good for 500 or so.
Of course the other hinge is starting to go as well...I'm sure it will be
easier, I already went down most of the false paths.
I have a few pictures of the completed job and that scary-looking bit of
pipe -- anyone in a hurry just ask for them, and I will eventually get them
up on the website for the patient folks who might be interested. No
in-process pictures, I was heavily under the gun and I worked all night on
this as it was.
But you really wouldn't want that frame to collapse in the field, could
noticeably complicate a camping trip. Might want to take a look at
it. The unworn hinge is contained evenly within the side-plates, with a
little margin all around. A worn one will protrude more or less. A really
worn one will look like it's falling out.
