In investigating this failure and solving it, thanks need to go to John. A single pin on the selector shaft had failed meaning that where there was no pressure to stop the cog from being spat back out when it was engaged. Obviously failed or was vibrated out during the race and hence it worked before and failed in post race scrutineering. Oh well, easy to engineer a more robust solution I guess and should have it sorted in time for Cadwell Park.
When we refitted the reverse mechanism with its new pin, we noticed that the angle bracket that locates the front also has a centre hole that was too large for the bolt. This opens up the potential for the front (i.e. cog engagement end) to drop down if that one bolt loosens slightly. Another potential point of failure, so duly fixed, thanks to John.
Whilst I am talking about things under the car. Here is a picture of the scrapes to the undertray from when I came off the track during the first race at Snetterton. Nice angle don't you think (front of the car closest to camera location)

What a bummer on the gear box hey. Thanks for doing this blog though I am really enjoying keeping in touch with how it’s all going although it sounds like you might be doing a bit too well for your first season, you won’t be popular! Also pleased to hear you had a good time at Springles, I’ve not managed to get there for a couple of years now and have to cope with Soul Survivor for work, not that there is anything wrong with Soul Survivor it’s great but aimed at those slightly younger! Keep up the good work. God bless.
