some escape for the single penny, delivered halfway around the world

13pc of 5g syringes of varying grits, $10.50 w/ free shipping.

I might have been able to have paid a little less. I just bought
from the lowest price vendor in the buy it now option. I paid $10.44
for 12 syringes.

I bought the same dozen from the same seller . Dan , I have a bearing race
that's pressed into a hole in a Harley 3 speed case . That race was
perfectly fitted to the clutch gear before I pressed it into the case . Now
it's out of round ... thus the need to lap the race . I'm wondering if it's
worth the trouble of peressing it back out to check the hole and the race .
Might be that the race is perfect and the hole is out of round , might be
variations in the thickness of the race . Either way it's unacceptable as-is
with OOR .0015" total
Should I decide to lap it in place , what material do you suggest for the
lap ? I have on hand lead , wheel weight material , aluminum , and several
grades of steel . I can cast anything but the steel directly onto a mandrel
for machining to maintain concentricity - I will be using a guide bushing on
the other side of the case to maintain alignment . I started an adjustable
lap set several years ago , but it never really worked out like I wanted . I
did learn a lot though !
