The Hub now then there's a question, I looked on the web to see what others had done, I also looked at Jack Difazio's patents, however the drawings are not upto much and give very little detail, all the other images I could find are of completed Hubs with little or no info on the details, having said all that I decided pretty early on I wanted to do my own, its basically a kingpin setup, I decided I wanted taper roller bearings, the rest was designed around this, the main problem was making it small enough with enough steering lock, and with some steering offset, also making the kingpin bearings adjustable for preload without removing the wheel, other problems to overcome where machining the external and internal splines with the equipment to hand, I ended up designing my own splines loosely based on the Torx system, this worked very well on destructive test pieces, other major obstacles are bump steer and anti dive levels, I used Tony Foale's suspension software for the anti dive calcs, this is set at 50% digressing, the bump steer I did by animated cad drawings, I also use this method to draw the suspension links front and back, in tests up to now on full bump I have 2 thou deflection at the bar ends, I have ridden the bike down our lane without power, brakes or handle bars!, and it steers pretty neutral, this only happened when I brought the bike to the new house, I couldn't resist, I don't claim to be breaking any new ground here, I just wanted a CHS bike, but I also wanted to see if I could do it in my home workshop, besides I could not justify the money to buy one, I still have a lot of work to do, the main parts left to make are the Rads the fuel tank and the *@*#**&* Wiring which I don't enjoy....
