The jig uses the same controller we used for the FVTX cables. | |
The coil heater is 40mm OD. It is wrapped in thin Aluminum, and held down by a thin sheet of Al. In between the heater coil and the wood support is 6mm of insulating foam. | |
The upper form also has 6mm of insulating foam between the thin Aluminum and the support block. With the foam, the support blocks do not heat up, and the heating element cools off quickly. | |
The foam also provides a snug fit.

The mold is 180° with r=20mm. Note that in the previous photo the cable does not emerge from the clamp at this angle. After 4 minutes in the mold at 100°C, the power was turned off. Air was blown around the mold such that the temperature fell to 50°C over 3 minutes, after which the mold was opened. The cable comes out with a 90° bend, and r=xxx. | |
Far from the bend, a small area of delamination was spotted. I'm
not sure if this was present before the bending operation.
