Bentley Sheet Metal Floorboards.

We have submitted a complete set of alum. floorboards covered with rubber .060" thick by the Goodrich Rubber Co., Burton, to E.{Mr Elliott - Chief Engineer}

They have been approved of for rubber adhesion and the question of production will be seen to by the Order Office.

The method of screwing the boards down was discussed and the alum. block, die cast, using cheese head screws was approved.

(1) For the alum. boards already made E.{Mr Elliott - Chief Engineer} is having a modification made to the steel centre support rail on the front board, to improve the gas tight joint. The first boards are to have the alum. blocks fitted and brass screws are to be used.

(2) A second stage in production will be a modified steel support rail to the front board using additional screws.

(3) A third stage may have to be introduced with a new rear board to suit the isolated change speed lever at present undergoing 10,000 miles test. The cost of making expensive dies should be watched as this modification may be affected.

The weight of complete set of boards, rubber covered, is 14 1/2 lbs. Standard boards, 16 1/2 lbs.

Since rubber is only really required for the joint between the two boards, we are experimenting with leaving this off the surface.
