Repeat steps 1 and 2 after busings are installed

(See

steps 1 & 2).

Just as earlier if the stone is used parts it is used

MUST

be washed and dried . Make certain bushings are

flush with castings and there are NO burrs on the top ID of
bushings.

(figure 31).

Check to make certain that the dowel pins are in place in

any new castings and that the location corresponds with the
mating casting. Before inserting any dowel pins check to make
certain holes are clean, the top of the holes do not have burrs.
To insert dowels hold the dowel in alignment with the hole.
Gently start the pin into the hole straight, tap lightly with a soft
hammer until dowel is seated into hole.

(figure 32).

Note as

shown, dowel pins have holes in the center, this is for the
studs to go through.

Remove the shaft end cover from the vice and turn it over

180° and re-insert it into the vise with the splined side up (figure
