Sandy,

I think the narrowness of those wheels will give you trouble on soft beach
sand. Better to use the big 'Buggy Wheels' that they use for launching
Lasers, Sunfish, etc.

However, since you have what you have . . . try this.

With sticks or string, 'lay-out' a 'T' shape that the inflatable will 'fit
on'. Get some steel rod {Stainless would be best, but EXPENSIVE}the same
size as the axial hole in the wheels. This will be the 'wheel axle' so take
into account the width you laid out, the thickness of BOTH wheels, plus at
least an inch per end for threading a nut, or other method of attachment.
Really simple would be a couple of heavy washers and a cotter pin.

Get appropriate lengths of Schedule 40 PVC pipe . . . at least 2in size. . .
.. for 'axle support tube' and 'handle'. Also get one 'T' in a LARGER size
that will slip OVER the 2in pipe, and one 'slip fit' end cap. You'll also
need some Stainless 'wood screws', a couple of pieces of hardwood or heavy
polyethylene, or Nylon, etc.

Drill a hole, transverse, through the rod, about an inch back from one end.
Deburr it and put on a large, heavy, flat washer, then insert a cotter pin.
{OR drill the hole, thread the rod, put on the washer, screw on a nut, and
insert the cotter pin}. Now put on one of the wheels, plus another washer.

Cut a piece of the PVC to the 'between the wheels' length plus a half-inch
or so. Make some bushings . . . O.D. to fit the pipe, I.D. to fit the steel
axle. Insert in the ends of the pipe and use at least 4 screws to hold in
place. Mark the center of the pipe. Now put two more marks so that the 'T'
can be centered.

Put this PVC on the axle, drop on the 'T', add another washer, the other
wheel, two more washers. Mark for hole, take apart as necessary, drill &
deburr hole, re-assemble & insert cotter pin. Center 'T' and secure with at
least 4 screws per 'leg'.

Insert PVC pipe in 'T' measure for a comfortable length, and cut. Attach one
end to 'T' with screws, and Cap to 'hand' end.

This is your 'basic Hand Cart'. You can add 'slings' or 'centering pieces'
to prevent the inflatable from getting rubbed by the wheels, or just make
the 'cart' wide enough to have extra space between the wheels. Obviously, it
is also easy enough to assemble 'on-site' so transporting it is equally
efficient.

We're going to be heading down to Baja in a couple months and plan to
bring our 10' inflatable boat along. It weights somewhere around 100
lbs and I'm planning on launching it over the beach. My problem is
that hubby had a stroke a few years ago and I'll have to do it myself.
I'm hoping to add some wheels to the transom to make launching easier.
Has anyone done this? Any suggestions or web sites w/plans??? I
already bought 2 10" (inflatable) tires from harbor freight. Thanks!
