Hi Andy
 
Looking at the photo of the rear wheel slot - make sure to leave enough gap round the rubber tyres that allows for wheel flex.
 
If the tyre is close to the fairing then if going round a corner e.g. at 30mph the wheel flexes and subsequent tyre rub can result in an interesting explosion that results in very exciting sideways travel
 
You may also have seen this beauty of a wooden velo in this blog:
 
Good luck with the building.
 
Regards
 
Brian.

I concur with Brian having departed backwards into the undergrowth at 30 mph at Lancaster for that very same reason.  You don't get a second chance when it happens!

I made the wheel slot very wide, then "duck taped" it closed so the tape nearly brushed the tyre, it's amazing when the tape wears as to how much rear wheel deflection there is.

Good to know. There is a fair amount of clearance already but any estimates of how much needed

nope, it depends on how flexible "your" rear end is? You could try having somebody sit in it (same mass and position you will ride in) with the brakes on then push the rear triangle to one side on the rear drop outs, just before the tyre lets go will be the maximum deflection (something break though, not my responsibility).  Not very scientific I know

What you silly boys need to do is slow down a bit - If you will insist on going round corners at 30 miles per hour then you are going to have problems...
 
I've never had any problems like that...
Oh, I see...

Pah will crash test dummy testing at reading velodrome once the base is mounted and up and running again ahead of building the bodywork.

Rear end is all kmx so overbuilt steel, doesn't seem to flex and with Alan on the slow down for corners anyway 😄

Given I now have carbon seat going spare I will line that up and fit to the frame in the next week or two so I can race a naked woody at hillingdon and shakedown the running gear ahead of strapping the body on
