Bishop Cam Steering

[GRaw505@aol.com]

Hi people! Sorry I haven't been in touch for a while - reformatted the HD and lost everything! When I bought Penny's TC a few years ago, the steering worm (is that the cam?) had a gap of about 3/4" missing in the dead ahead position. To get the car going, we welded in some new metal, lapped in the peg and hardened the whole thing. It wasn't great being a bit tight in the middle and too loose everywhere else. Eventually I was able to acquire a new cam and it transformed the car. Nevertheless, the amount of play wasn't satisfactory so we made up a little locking bolt with a ball bearing on the end to bear down on the centre of the output shaft. This improved things greatly - is this a Tompkins Kit? The next stage is under way as we speak. A chum, who bought his car in the 60s, has a turret on the top plate with a huge spring inside which bears down on the output shaft in a similar manner as my modification. The difference is that the spring takes up all the slack from lock to lock - hence no play at all at the steering wheel. p.s. could someone please forward all the details again re the web site etc Best Regards Geoff Rawlings

A Tompkins kit is a specially cast/machined aluminum top cover for the TC and TA/TB ) steering box. It has an adjusting screw over the sector shaft, the adjusting screw bears down on a flat needle bearing which contacts the top of the sector shaft. The Tompkins kit makes it easier to adjust backlash in the cam/sector shaft and also reduces friction on the top of the sector shaft. It is a more refined solution than the bolt bearing on the center of the sector shaft although the concept is similar. Current Moss price is $82.95 each. I have manufactured a batch of these top covers/Tompkins kits and sell them for $50.00 US$ each, (this includes the machined aluminum top cover, needle bearing assembly, screw and lock nut, 3 correct length BSF bolts). plus $5.00 US$ postage and handling. I do not include the top needle bearing on the column as this is a poor application of a needle bearing and it rarely fits properly. Email me if interested in more information.
