Process is simple:
- Grab your 5' aluminum straightedge/ruler to measure any object in the shop
- Get a cell phone call
- Set the ruler down on your miter saw
- Finish the phone call
- Respond to wife's request for help in the house
- Answer phone again and talk to son for 15 minutes
- Go back to shop and drag 8' piece of Oak off of lumber rack
- Get another call and lay Oak on miter saw while fumbling with the phone
- Talk on phone for a few minutes
- Measure Oak with tape measure
- Cut Oak at mark
- Presto - two rulers.
Note: Some minor tweaking is needed to get ends of ruler to line up with ruler graduations.
