Thanks for
your inquiry on regrinding Ford Model A & B camshafts.
These profiles were designed by Harvey J. Crane, Jr. after his 45 years
of frustration in trying to regrind the stock Ford Model A camshaft with
the problems of grinding into the core (barrel).
WHEN A CAM LOBE IS GROUND INTO THE CORE THE RESULT IS A BADLY BENT CAM!
|
Undercutting the core (barrel) solves this problem.
Camcraft Cams will ONLY produce these reground Model a & B camshafts
with an UNDERCUT BARREL! This is an EXPENSIVE process, therefore the
TOTAL COST is considerably MORE than a normal reground Model A camshaft.
After undercutting the barrel, the STRAIGHTENING PROCESS requires more
time than REGRINDING!
Please call Charles Reichard for a quotation on regrinding your GOOD
USED stock camshaft. Your used camshaft should have a center
bearing minimum diameter of 1.557 inches (new is 1.560 inches).
These profiles are produced on a Berco grinder using master cam plates
from design data by Harvey J. Crane, Jr. These CNC masters are produced
on a Landis 3L CNC camshaft grinder. This 3L machine sells for $800,000!
