Safety Hood

Any time a chisel or a plane iron is hollow ground, you're going to produce sparks — and a lot of fine, black grinding dust. I wanted to contain both of these by-products, so I added a safety hood to the grinding jig, see drawing at right. Besides keeping the dust from spreading out and covering your saw, the hood also covers the opening in back of the divider walls, so the sparks and dust can't get down inside the saw.

SAFETY HOOD WALLS. To make the hood, I started with the walls (I), see Fig. 6. After cutting the V^'-thick blanks to size, I first beveled the back corner 45° to match the dividing walls on the arbor assembly.

Next, I laid out and cut the front edges of the hood walls with a band saw, see Fig. 6. These simply provide clearance so more of the grinding wheel is exposed.

FLANGES. To secure the hood to the table, I glued and screwed W'-thick hardboard flanges (J) to the the bottom edge of the walls, see Fig. 6. Then I set the wall assemblies over the threaded inserts in the base and marked the positions of the shank holes on the flanges, see Fig 6a.

After these holes were drilled, I mounted the flanges and walls to the base with studded plastic knobs, see Fig. 7. Now the openings between these two walls can be covered.

TOP & BACK. To enclose the hood, I

simply connected the walls with hardwood and hardboard pieces. First, I measured from outside edge to outside edge. Then I cut a hood top (K) and back (L) from V^'-thick hardwood, see Fig. 7. (I used hardwood since the hood gets lifted by the top piece.) These pieces are cut to match the edges of the walls (I), and the back has its top edge beveled 45° to accept the hood panel, see Fig. 7a.

Also, I relieved the sharp edges of the top piece, see Fig. 7a. Then I glued and screwed the top and back pieces to the walls of the hood.

PANEL. Finally, the hood panel (M) can be added between the top and back. This piece is W hardboard and has both edges beveled 45°. This way, when the panel is glued and screwed in place, it fits tight against the top and flush with the back, see Fig. 7a.
