Speaking of wobblies -- with Chamby M-style 1/2" 8-track, does rounding
the corners on the pinchies mess up the head contact on the outer tracks
(remember how narrow the tracks are)? Is the other part of the solution
to wobblies softening the rubber and/or replacing if softening does
round them well enough? How does felt-matting factor in to good push pad
performance and adjustability?
It's the pad that insures good contact of the tape with the head over all the tracks. The roller is just a revolving pressure pad and the better it drives, the better the machine will sound. Grinding the rollers can only improve things.
And, BTW, is the pinch roller on the 400 the same diameter as on the
Chamberlin M's with a similar axle and connection?
Don't know! The rollers in the Chamby 300 we have are indentical to our rollers and at 3/8" wide they will certainly suit 1/2" tape even after grinding. Remember, when we grind we reduce the surface area of the roller by 1/3rd yet standard tape drive is improved because you are concentrating the drive area.
Martin, anyone - come on...help us out...
