Sanders - random orbital vs orbital
Here comes another newbie question (or several actually)...
What's the difference between an orbital sander and a random orbital? Presumably, the random orbital has a different sort of movement, hence the "random". But is there a clear difference in the applications that each are suited to?
Same question for 1/3 sheet and 1/4 sheet orbitals? Is it just a matter of 1/4 sheet being smaller & easier to handle?
Which all leads to... If you had only one power sander, what type & size would it be?
