Dimensions:

• spread between wheels: 16.375"
• height- fuselage bottom to axle center: 5"
• average thickness: 0.125"
• section width: 2" at fuselage tapered to 1.25" at axles.

Carbon fiber layer composition:

1. 1) 1 layer .007" unidirectional CF laminate, full length
2. 2) 2 layers 0.3oz CF tissue
3. 3) 1 layer .014" unidirectional CF laminate, separate pieces for each flat section
4. 4) 4 layers 0.3oz CF tissue
5. 5) 1 layer .014" unidirectional CF laminate, separate pieces for each flat section
6. 6) 2 layers 0.3oz CF tissue
7. 7) 1 layer .007" unidirectional CF laminate, full length

Construction:
All the above layers were laminated at the same time into a flat sandwich using West Systems epoxy to fully saturate. Excess epoxy is squeezed out using paper towels then the whole mess is placed between two sheets of polyethylene and again squeezed with a wiping action. It is important to eliminate air pockets. The bundle is then placed on edge into the form which consists of nails standing vertically in a piece of wood. The outer layers of continuous .007 CF laminate holds everthing together while the separated inner sections of .014 allow it to bend at the joints to form the corners of the gear. Additional nails are added afterward to adjust the shape as needed. Alignment of the axle mounting surfaces and any desired toe-in should be carefully checked and adjusted at this time.

Let it cure overnight. Then you can pull it from the form and begin shaping the edges and cleaning up the flash. After the gear shape has been cleaned up there are a few more laminations to be made. First, CF tow is added to the inside corner bends of the gear to build the thickness up to about 3/16" at the axles and to 1/4" at the fuselage corners. The tow is cut to lengths of about 1 to 2 inches to help make a fillet in the inside corners. The tow must be oriented lengthwise to the gear. When this is cured it is shaped to form a smooth fillet. Then sand the whole works. Finally a single lamination of 2oz fiberglass cloth was added to each side of the gear to provide protection to the surface. After sanding the completed gear give it a final thin coat of just epoxy resin to fill the exposed pores of the glass and give it a finished look.
