Trev, They are about a 5 thou interference fit, even with the hub at -18 C and the crown wheel at 120 C it took 4 tons to press them together. I have yet to check for runout but will be doing that before I weld it. Backlash is between .006 and .008" The hub is new and I assume square at the mou...

SFA in other words.

Kym, I'm having the same issue. I bought 2 E sized bottles off speedie gas as the monthly rental on 2 bottles ( got a mig as well) was killing me for the amount of welding I was doing. Tig sucks up roughly twice the gas mig does and I'm on my second bottle of argon and its only 1/3 full atm. E sized...
