OK Then it's just me, I am more Lazy than Susan !, I have just made mine with a Scaffold board, A bit of 14" by 1" and an old Vincent Wheel Bearing.
Works with my Special, Which is a bit tall, So I stood by the side of it, Must admit I nearly dropped it a few times !, Which is why our friend on the Video stays sitting on it ??.
But really you must have room for a scaffold board ??.
I think I can make it a bit more steady, But my floor is tricky, There is a pit in the middle and the cover boards
are just below the surface.
I think it will be more easy with my other Bikes ?.
Cheers Bill.
