Step 6.
Use a 1/4” drill bit and a 1/8” drill bit to drill out the
holes in the plywood squares for the axle and 4-40 bolt. Use
caution that you do not split the wood.
Step 7.
Mix approximately 1 ounce of 30-minute epoxy. Epoxy
both plywood pieces to the inside of each wheel pant, making
sure the epoxy does not clog the openings in the wheel pant that
were drilled. The smaller hole will have to be drilled out later.
Step 8.
Locate the axle, lock nut, wheel, and two wheel collars.
Mount both axles to the landing gear using the large lock nuts.
Once mounted, you will have to trim each axle using a Moto-tool
and a cut-off wheel. Use caution when cutting the axles and wear
protective goggles.
Step 9.
The wheel pant can be trial fitted to the landing
gear/axle. You may find you will have to open up the large axle
hole a bit with a round file due to epoxy seeping into the
opening. Adjust the wheel pant in reference to the bottom of the
fuselage so the bottom of the wheel pant is parallel to the bottom
of the fuselage. When you are satisfied with the alignment, mark
the small hole opening onto the wheel pant.This mark can be
made by passing a small drill bit through the hole and marking
the surface of the wheel pant. Remove the wheel pant and drill a
3/32” hole in the wheel pant as marked.
Step 10.
Repeat Step 9 for the other wheel pant.
Step 11.
Epoxy a 4-40 blind nut into the small hole drilled in the
wheel pant /plywood brace inside the wheel pant. Allow the epoxy
to cure completely before attempting to tighten the bolt down.
Step 12.
Mount the wheel pant to the axle and screw in the
4-40 bolt into the small hole above the axle, so that it screws
into the blind nut. Before tightening the 4-40 bolt, slide on a
wheel collar, the wheel, and another wheel collar onto the axle.
Step 13.
Tighten down the 4-40 bolt to secure the wheel pant to
the landing gear. Position the wheel in the center of the wheel
pant opening, and retain it there by positioning the two wheel
collars (on either side of the wheel) so that the wheel is kept in
the center of the wheel pant opening. Tighten both wheel collar
screws snugly once the wheel is properly positioned.
Note:
A drop of Locktite
®
Z-42 on the wheel collar screws
will help keep them from coming lose during
operation. Repeat the process for the other wheel.
