Drilling advice needed

[ChrisCar6]

Thanks for the suggestions. I left them with my local engineer who was going to try lathe or grind or (most likely) turn up new ones.
The bogie is almost finished, the race is on Saturday and I'll need to fit the bearings, bed in the brakes and get a handle on the handling before then! Had a drive up & down the course this evening and it looks straightforward unless they put chicanes in.
It shouldn't hurt too much!

Sounds like a great project and a lot of fun. Looking forward to seeing some video, hopefully with the wheels pointing down the whole time.

I take it you are going to post some pictures of the missile in all its glory?

Oh ye of little faith!
Wasn't last, didn't crash, nothing broke! That's a first! Roll on Abingdon.
Good fun - touched 50mph on the way down. First run I didn't wear goggles, and between wind and vibration couldn't see well enough to go too close to barriers and edge of tarmac - sorted for subsequent runs. There were a couple of big crashes, but not me.
Aerodynamics seem to be the big thing. and weight. i loaded up the (genuine) soapbox on mine with 25kg ballast, on the basis of momentum through corners, but the top two carts were lightweight carbon jobs - one built by the Lola factory, and the other by a university advanced materials carbon fibre research unit. Bet they didn't use hammers. So, maybe a new approach needed next year.
I haven't found any video yet, but it's on Dave on the 11th July I think - probably not me though!
I failed scrutineering on some sharp edges - hence the rubber balls taped on strategically. The name is a bit contrived - mu is the coefficient of friction - a curse of gravity-powered machines. And everybody knows that bogies are made of mucus......

Here's a vid from the luge race - gives an idea of the course. Mad bastards.

Nice vehicle, maybe all you need is a good fairing then? I bet that was a lot of fun, I'd love to have a go at that. That luge looks good too, that's one thing I always wanted to try on ice.
