- 1/8″ drill bit and drill motor
- 4 butt hinges about 2-1/2″ in width
- Screws for joining the hinges – you’ll see this in a moment
- Strong wood screws for attaching hinges to the bench apron and the mounting board.
- Bolts, nuts, washers for mounting grinder to the mounting board.
Prepare an appropriate size mounting board using a strong, stable material – I used a piece of laminated bamboo stair-tread. (Figure 1) I’m showing the mounting board bottom-side-up. I include feet so the bolts attaching the grinder clear the bench top. You’ll see this in Figure 4.
Assemble the hinges in pairs as shown – you’ll need the double fold so the entire assembly clears the table top.
Attach hinges to the mounting board and the front edge of the table apron as shown in Figure 3.
When projects call for the full surface of the work bench, simply swing the grinder down to its storage position, as shown in Figure 4.
I do a few shows and wood turning demonstrations each year. This requires portability. With the grinder in the “up” position, I simply tap the hinge pins out of the top pair of hinges. Now, the grinder – still mounted on its board with jigs in place – becomes a portable tool.
You can take a similar approach with other bench-top tools in your shop. The weight of the drill press suggested larger hinges, and I took time to reinforce the bench apron with some good, tough hardwood. The spindle/insert storage on the sander required special consideration so the loose parts wouldn’t spill whenever swinging the tool into a stored position.
