Roo Man's Room / Re: wheelie bars

I'm designing mine at the moment.  Had the same concerns with a single point up high.  I don't believe I'll ever break a bar or mount on a launch, my concern would be going into the wall backwards. I feel as though in any other form of motorsport something like a suspension upright or an aerofoil etc would be designed to shear in a safe way and detach but I can't figure out how you could apply this safely to a wheelie bar ?

thanks I thought about doing it this way but thought it may pucker on the curved edges,  think I may have more success making it out of two pieces, a flat spar clamped to a flat surface and then a 3/4in wide flat piece wrapped around the outer edge and tig'd ?

your right yes the track is used in the program.  The wall is a sound barrier, the site has been hosting motorsports of various kinds since after the war but is faced with all sorts of problems with the local authority over noise and local disruption.  Racing can only take place on certain weekends and there is a very strict curfew of 5pm.  It's a grass roots track minimal facilities but ran by very nice people who do a good job with very little resource. The site is also used as an airfield, on one occasion a micralite emergency landed at the top end as two alky funny cars sat in pre-stage.

I've seen modern CNC aluminium ones for front wings, but how were they traditionally made ?

Hi, room for one more, another racer from the UK. 

Had a little 120in slingshot with a V6 then V8, ran 12.01 @ 111mph.  Graduated to a 23T altered, ran that for 3 years, ran 8.49 @ 152. Sold the altered to have kids, and decided to build another slingshot, currently 75% built, 138in 420cu in stroked 400 SBC injected on alky, chutebacker half body, 5 point cage etc.

Will post some pic but here's a video of some testing with the altered to start you off.
