I kept taking .002" passes, so .004" on the diameter and stopped when I got 1.040" on my caliper. That gave me a .006" interference fit. A little on the tight side but I didn't want to take another pass.
I took the fork and race into my sister's kitchen and heated the race over one of the burners of her gas stove for a minute and dropped it on the fork and got it started and quickly went back to the shop and got a tube and ball peen and pounded the race home.
