Billet top yoke, what material/thickness?

[wild foamy]

Hey peeps.

I've given up trying to find a top yoke to fit F.U.C.R, so im looking in to making one, I have the machines necessary available but am undecided as to exactly what spec of material i need.

 

I've been looking at Alluminium 6082T, but am stuck between getting it in 5/8 (15.9mm) or 3/4 (19.5mm), the originals were closer to 3/4 but had webs machined into them, this one ideally is going to be solid, just a couple of 10mm holes to mount my dial brackets but thats it, the ignition switch is now down beside my left knee and telltales inside the clocks (what a f*cking job that was, need fingers like a gynecologist)

I'd stick with the 19mm as most top yolks I've seen are that size

its the area that clamps around the stations which is the factor.

 

T6 alloy normally does the job, just inspect for cracks now and then
