That is correct, just the elastomeric sheet. I was attempting to comply with
the following extract from PAGE FUS 3 - 11, dated November 6, 1992, of the
KIS TR-1 Builders Manual:**
It is recommended that a thin layer of rubber sheeting (inner tube rubber
or similar) be lightly tacked to the upper mating surface of the landing
gear to avoid local concentrated loading of the composite. Apply a thin
layer of a thick mixture of FLOX to the rubber covered upper surface of the
gear, and apply added flox on the recessed surface around any shims which
may have been added to the recess area. Lightly torque the bolts holding the
gear in place, and correct any positioning before the FLOX cures. Clean away
surplus FLOX before it becomes fully cured. The FLOX will provide a uniform
bedding for the gear, filling curvature and voids. The rubber should provide
for ease in separation of the gear from the recess, as well as providing
cushioning against the destructive effects of point loads into the
composite. If there are too many voids in the FLOX covered areas, the
process of coating the surface with FLOX can be repeated concentrating on
void areas, and squeezing out surplus FLOX."##
2) "What did you use on the bottom of the landing gear cross bar?"
Just the two steel retaining straps provided with my kit. The straps are
plain flat bars about one inch wide and 1/4 inch thick. Here is an extract
from the same page as above:
"Drill a matching set of 5/16-inch holes in the steel (4130) retaining
straps, and countersink to set the bolt heads flush with the surface. Using
the large bearing washers provided in the kit on the inner fuselage side of
the mounting holes, and MS 24694-S 178 bolts, trial assemble the gear legs
to the fuselage (use minimum torque on the nuts to close up gaps but not
deflect structure). Check that the assembly is square to the aircraft
centerline, the legs are level on each side, and the axle centerline will be
located at STA 73.5. Use thin wood shims tacked in place with 5-minute epoxy
to correct any noted misalignment."
I used AN5 bolts with no countersinking. It is a pretty crude looking
installation, just like some piece of farm machinery.

I got this idea but I bought a truck inter-tube and cut
the size I needed and put that between the gear and the fuselage."

EXCELLENT info OC. So if I read this right you don't have any plate (radius
or non radius) between the top of the landing gear cross bar and the landing
gear flox bed, just the elastomeric sheet. What did you use on the bottom of
the landing gear cross bar?

Galin,
OC's method follows the manual instructions for the TR1. I'm not sure what the
manual says about the TR 4. I insisted on Grove landing gear components with
my kit because people were dissatisfied with the performance of the supplied
Matco brakes.
I recommend using the Grove radius blocks. I put about 12 layers of glass
Between the fuselage and the blocks
at each attach point to spread out the shock and strengthen the attach points.
In the cabin I also put about 12 layers of glass where the bolts come through.
The nuts are tightened down on a fender washer against a thick rubber washer
to absorb some shock. See picture in following message.
