Can anyone tell me the proper "5 minute epoxy" to use in the flex shaft. Loctite has like 12 diffrent versions. When I read each one I can find a reason not to use it on the flex shaft. Some say for most plastics (isn't the shaft rubber?), some same not to be put on anything flexable (wouldn't the flex shaft... flex?) I keep looking for "to be used on a Carvewright Flexshaft" but to my amazement it isn't listed.
