All worked well, I believe heating the spindle, putting a small lead on bushing & oil definitely made it much easier than described. @ .002” interference fit I’m sure without the three things mentioned would’ve been a lot harder & more potential for not fun issues
!
Steps taken;
-Broke edges & polished about a 1/16” of the end of bushing I pushed in to give a lead to insure perpendicular & not cocked entrance.
-put spindle forging in oven & 170 ( as low as Mom’s stove went ) & let heat 2 hr.
-Put bushings outside @ 15 degrees weather.
-1 hr. later took one spindle out with gloves, put copper on vice jaws, put one bushing @ a time in & seated with the vise, probably 50lbs+ of force on vise handle ( used machine oil on bushings ). 1/16” polished lead definitely kept it straight & square to c/l of hole.
-Took other spindle out of Mom’s oven & did all again.
-Reamed with line reamer via adjustable wrench.
