My lad is into kart racing and is quite competetive, I am the one who gets to do all the jobs other than driving the kart. We are looking to gain an edge on engine performance and we plan to build a dyno to optimise our engines. The dyno will be of the inertia type and the electronic interface will be DIY employing an Arduino Package.
The key to this working accuratley is by matching the inertia of the flwheel to the weight and acceleration of the kart and this is why we need a 600 x 25mm steel flywheel.
My lathe can only manage 300mm od. so I was thinking along the lines of machining the od, 40mm bore and 6 x 10mm holes on150mm pcd, all at one hit using a 12" rotary table on my bridgeport.
Can anyone forsee any problems doing this, especially the od.

Dave
