      i had posted something on this matter a few years ago in LETpress when the
      matter came up. here again is my solution. perhaps it will help someone.


      i got a sweet and well cared for os c&p 8x12 from the basement of an old
      fellow who used it for years exclusively for printing catholic memorial
      cards. the press was plated in bronze powder. $1. i also bought his 26" c&p
      cutter w/spare blade for $175... thanks Arthur.

      upon initially putting the press 'on line' and to eliminate any stray
      variables i set up the press with new solid steel cowan trucks and buna-n
      form rollers. i would recommend this combination for anyone interested in
      getting the finest quality work from any platen. avoid morgan expansion
      trucks at all costs.

      for whatever reason, the roller tracks were what seemed to be exceptionally
      low. not sure why that was the case. it is certainly not due wear, the
      variance being a gross disparity. perhaps it was to enable use legacy of
      type of varying heights. old no. 27227 dates from 1898 i believe. there was
      surely odd height type out there in cases.

      so what to do?

      fortuitously, a sheet of formica happened to mic out to the 'perfect'
      thickness at .045" to bring the rails to .918 +/-. conveniently, formica is
      nicely consistent in thickness.

      i cut two strips the width of the rails on the glider and using 3m 665
      double stick tape, affixed the formica strips to the rails. using a chisel,
      i tapered the ends to yield a smooth transition at top and bottom.

      i have been running the same strips for 8 years. over time they have
      'glossed' up a bit from many thousands of impressions and from wiping them
      down after wash up. i am actually contemplating replacing them, as, if the
      rails and trucks are not kept clean, there can be a tendency to slurring on
      some forms.

      as a side observation, i'd have to guess that the formica, being softer than
      steel and acting as a buffer, has significantly slowed the wear of the steel
      trucks.

      so there you go. formica strips. beats the hell out of tape if you can make
      it work.

      if anyone with rails out by .045 would like to try this solution i can
      supply strips if you supply the length and width of your rails.
