Chris, I have a whirlwind. They aren't made any more. They're okay, but don't blow my hair back. Leaky which drives me insane. It seems like I'm constantly replacing an o-ring, or fighting something leaky. Air costs too much to pump up.
As already said, good blades are key. I don't cut anything on mine that is super critical for finish quality. I don't do drawer fronts, or fronts and backs for drawer parts. Door parts and face frames parts it's good enough though.
I have two of those saws. One is just sitting on the shelf, I've never even used it. It was in good shape at a local auction, and I snapped it up for a decent price. My Tigerstop is getting a little wonky too. My plan is to can both saws and the stop, and replace them with Northfield's and Razorgage stops. Some days, I should really use another cut off station.
Dust collection on the whirlwind saws is terrible, bordering on pointless.
I personally don't think gang cutting will get what you want. Too hard to get everything sitting nicely in my experience.
Thank you for the shop comment. I'm very proud of the nightmare/slave master I've created. LOL
