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?

I think you mean "finishing" rather than power sander? If I could only have one power sander I wouldn't be without my big Makita belt sander. They really are impressive tools. I use mine for all manner of things, including shaping wood and metal, apart from final finishing.

You've already got a good explanation of the diffs, but if I could only own one I would decide based on the kinds of jobs I was likely to be doing. For bigger jobs, a dual-mode ROS would be my choice. If I made mostly small items, a smaller ROS with a short throw to give a nice finish quickly. Need to sand in corners a lot? A detail sander works well there, or a 1/4 sheet orbital. Odd shapes? A profile sander is the go. So like most things, it's horses for courses.
At the end of the day, one sander can't really solve all your challenges. That's why I ended up with 4 or 5 different kinds.Cheers,

Thanks for the responses, and BobL you're right, my final question should have read "what type of finishing sander". I can't see myself having much use for a belt sander at the moment and I have access to a loaner only 15 minutes drive away when I do need it. There's also a 1/3 sheet there too. Both Makita.
Given a tight budget (which after some research pretty much rules out a ROS) and the presence of the Makitas I can borrow if I plan ahead, I might just get a 1/4 sheet or detail sander so that I've got something close to hand for the little jobs that don't warrant a 1/2 hour round trip.
So the next question becomes ... as far as I can see there's not a whole heap of difference between a 1/4 sheet or a detail. The overall size of the pad is not greatly different. The detail gets into corners, but you're committed to buying the right shaped velcro sheets. I didn't think to check if the 1/4 sheet ones have clips to take regular sandpaper. As I'm writing this I have just realised that the 1/4 sheets might be more powerful too.
This tool acquisition process just creates dilemma after dilemma!
