I'm replacing the outer shaft and the inner driveshaft, with a straight aluminum tube and a 1/4 inch diameter aluminum rod for the driveshaft.
The rod will be rotating inside of nylon bushings. The nylon bushings will be stuck inside of what Lowe's describes as "1/2" ID PVC Reinforced Braided Vinyl Tubing". So that the bushings are held snugly inside of the aluminum tube.
FWIW. Another way Lowe's describes that spacer tubing is "1/2 ID Braided PVC Tubing". It's a flexible clear plastic tubing with reinforcing material inside.
Question: Is the aluminum rod spinning inside of the nylon bushings going to cause the bushings to get hot enough to melt the plastic tubing, with everything closed inside of the aluminum tube?
Thanks.
