How to Use an Orbital Sander
- 15 seconds per foot travel rate:
Lessons:
- collect dust, so you don't get larger abrasive spots from dust clumps
- Go slow - pigtails will shrink
- Calculations - if 15 seconds per foot, we have 39 passes lengthwise for one passthrough - meaning 1248 feet - meaning 5.2 hours per 500 sf pad. Save 20% by not doing under stairs and cabinets, you have 4.7 hours per pass. 5 sander gang gets that down to 1 hour. Definitely could use a holder for 6-10 sanders. If they can be ganged - that would be awesome.
