Stack speed sensor

[timbarnes]

If any one of you out there is using a Stack speedo or tach timmer and uses the Caterham sensor mount, then read on.

The Caterham sensor mount, mount on the brake caliper. This over heats the sensor and they fail. This was confirmed by stack, who are unhappy with the way that Caterham mount their sensor. I think I have come up with a neat solution. A small bracket that replaces the spacer washer between the steering arm and upright.

The bracket swings back and under the steering arm, picking up on the same disc bolts that the old mount used to. The spacer washer was there to replace the no longer used disc stone guard.

It is very important that the sensor bracket is made with the same gauge steel size, or stainless steel, as the spacing washer. To see my idea, go to my web site at www.tbarnes.co.uk you will find a photo under technical tips.

Haven't finished my rebuild after an accident, so haven't had a chance to test the bracket, but I have full confidence that it will work Ok.

Funnily I came up with the same solution to mount the speed sensor for my Astratech logger at the beginning of the season. I just happened to have a strip of steel which was the same thickness as that washer.

Tim, have you spoken to Caterham about this? If so what did they say? I've had mine now for about 6 months and had no problems and it's been run on several track days. Did yours fail or did this come up in convesation with Stack?
