I asked the question earlier in a post about how the Shop Fox
oscillating drill presses operated - I found my answer in their manual
that is available as a PDF download at:

I also picked up my Shop Fox 15" planer, W1742, on Friday that I am
putting together. I checked out the manual for the Powermatic Model 15
planer and find the manual parts brake down the same. What do you get
in a Powermatic that justifies almost double the price other than a
name?
