Suggestions For Reaming
Valve Guide Stem Holes
1. Use high quality cutting oil.
2. Reamers are made to cut right
hand only-do not turn backwards
even a partial tum!
3. If using power, run high-speed
reamers
at 400 RPM
maximum, and
carbid~-tipped
at
700 RPM
max-
imum. High-speed steel reamers
for hand cutting.
4. The #5221 B universal cylinder
holding fixture is recommended
for
stem hole reaming, using
a
drill
press or vertical mill.
