Although it is able to be exchanged... The knob of MITCHELL is one piece construction and it is not built the bushings . So the looseness of knob increases by use . The knobs of MITCHELL and Cardinal are built by screws . Although it is able to be exchanged , the new knobs are not sold now . So I tried building bushings in knob . I used80B 0406 bushings of OILES . |
 |
OILES 80B0406 |
 |
Tools The drills . Epoxy glue etc . Sizes of drills are from 4.5 to 6.1. The steps of them should be less than 0.3mm . Two of bushings are used per a knob (no picture). |
 |
Drilling Drill the hole manually . Although the bushing of 80B4060 is designed for 6.0mm hole , the knob may be broken by the stress . So the last drill is 6.1mm . |
 |
Apply the glue Apply the glue after the check of fitting of bushings . |
 |
Apply the glue into the hole of the crank side . |
 |
Insert the bushing Insert the bushing . Although the material of the bushing cannot be adhered by the glue , the glue becomes the stopper of the bushing . |
 |
The opposite side is same too . The bushing had better be together inserted with the shaft . If a crank is worn, the A must be made longer. Remove the glue of the holes of bushings before hardening . If your glue is a type of 5 minutes , you will had better put two bushings like the figure . It is possible to glue together at the same time of two if your glue is a type of 30 minutes . In this case , the reliability becomes higher by painting the glue to the whole of hole of knob . |
 |
Finish Apply a reel oil to the bushings after a day . |
 |
But ! But the bushing cannot be used into the knob of 70's reels , because it is thinner than the 80's knob . So I must find the other bushings . |
