Arbor Assembly

Now it's time to work on the arbor assembly that's added to the top of the base, see drawing at left.

DIVIDING WAILS. The arbor assembly starts out as a couple '/"-thick hardwood dividing walls (D), see Fig. 3. Once these pieces are cut to size and shape, clearance holes are drilled for the hubs on the large pulley. (Each side will require a different size hole.)

Note: To decide which diameter pulley you'll want to use with your saw, check the chart on page 35.

CLEATS. Next, to attach the dividing walls to the base, I added a small cleat (E) to each, see Fig. 3. But before gluing the cleats in place, I drilled countersunk shank holes for screwing the cleat (and dividing wall) to the base, see Figs. 3a and 4a.

When attaching the dividing walls to the base, the pulley and drive shaft will need to be sandwiched between the walls, see Figs. 4 and 4a. And if you're not using a link belt (see margin photo), you'll also have to add the V-belt at this time.

MANDREL SUPPORTS. Two pillow blocks support the mandrel shaft, and these require wood supports to lift them to the proper height, see Fig. 5.1 cut the mandrel blocks (F) to size. Then I spot glued and screwed them to the base. (The shank holes have already been drilled, but you'll need to drill pilot holes for the 2'/"-long screws.)

With the mandrel blocks in place, slide the pillow blocks onto the shaft and then secure them to the mandrel blocks with lag screws, see Fig. 5.

Now the grinding wheels can be added to the shaft. To position the wheels over the grooves in the base, I used a couple %"-wide nylon spacers, see Fig. 5a.

PANEL & LID. At this point, the grinder part of this jig is functional. But before adding the carriage and tool rest, I decided to cover the exposed pulley and belt. So the last two items to add to the arbor assembly are a pulley panel (G) and lid (H), see Fig. 5.

These pieces are cut to fit over the front two edges of the dividing walls, and the edges where they meet are beveled at 22'/2°. The exposed edge of the lid (G) is cut at 45°.

This belt is made up of removable links, so you can easily adjust it to the size you need.
