Mark VII Restored Manual - V1.02 ā Donated without cost to the world-wide Shopsmith Community - Everett L. Davis 2016 24
ARBORS
Arbors (Fig. 43) are economically priced so that SHOPSMITH
owners can make it a rule to have each saw blade and each
applicable accessory ready-mounted, all set for placing on the
SHOPSMITH spindle in seconds. Only with SHOPSMITH is this
convenience available. The 1-1/4" arbor is used with 9" and 10"
saw blades. The 5/8" arbor is used for mounting smaller saw
blades and other accessories with a 5/8" arbor hole. The 1/2"
arbor is used with accessories having a 1/2" arbor hole. SINCE THE
SHOPSMITH MARK VII IS REVERSIBLE USE ONLY ARBORS HAVING
A KEYWAY AND TONGUED WASHER (Item Nos. 505505 and
505506). Ordinary arbors are not recommended but may be used
on the main spindle only and in forward direction.
DADO TOOLS
A wide, recessed cut designed to take the edge of a
board is cut with a dado. Of the two types available (Fig.
44) the MAGNA Dado is the most popular. It has a
special extra heavy blade which cuts a normal kerf
5/32"wide and is infinitely adjustable to a maximum of
7/8". Any width cut in between is possible with a simple
Allen wrench adjustment. SPEED-DIAL is engraved to
indicate proper speed for MAGNA Dado use.
The 6" Dado Assembly is a standard tool which employs
two outside blades and a set of inside chip-pers. The
size of the groove is determined by the number and size
of the chippers used between the blades.
Either dado tool must be used with a special Dado
Insert which replaces the saw blade insert.
Always check tool clearance by turning by hand before making any cuts with a dado.
