I get some great ideas from the posts shared on GTT. I can't compete with the big equipment owners, but here a few quick & easy projects that don't require much skill and have made my life easier.
1. Clip-on battery powered LED tail light
Add a screw eye to the seat back and use a badge clip to quickly attach the light when needed.
2. Miter gauge holder
Attach a tool hook to a Harbor Freight magnet (95 pound rating) to hold table saw & band saw miter gauges.
3. Dust collector central switch
Mount a standard light switch on/above the ceiling near the center of the workshop, drill a small hole in the lever, use a zip tie to attach a handle (a hunting arrow in this case).
4. Rotary tool bit holderDrill 1/8" holes in a 2" thick board and cut the back at a 10-15 degree angle to create a wall-mounted bit holder that can tolerate vibration without losing bits.
5. Wireless garage door control (Mounted)
If running wires is difficult, mount a battery-powered garage door remote to a switch plate by cutting and bending its visor clip. In my case, this location is at the top of the stairs coming up from a lower level garage.
6. Articulating arm for garage fan
To provide air circulation in an irregularly shaped garage, build an articulating fan arm from 2" PVC (reinforce the ends before drilling by using a rotary tool to remove the internal ridges from couplers, then slide a coupler fully onto each end, bonded with PVC cement).
7. Suspension arm for painting small objects
Use a leftover garage door railing bracket and scrap lumber make a removable arm that allows small objects to be suspended with string while painting.
8. Low profile, low cost TV mount
Cut a Bi-Pass Closet Door Track rail in half and use the two pieces to create a sturdy, cheap, low profile TV wall mount.
9. Frustration free wire clothing racks
To avoid getting hangers caught in older wire closet shelves, block the upper gap with a piece of thin metal or wood.
10. Corner wire closet shelves without mid-span supports
To reclaim shelf space broken up by angled metal supports on corner shelves, attach wooden supports behind the shelf lip to tie the shelf segments together (secure with zip ties).
