I just came in from my shop where I had occasion to use two of my favorites.
One was a Porter Cable 1/2 sheet sander, the other a Porter Cable bayonet saw. Both have not been made for years, both have heavy aluminum castings; IOW, they were made when PC made excellent tools.
The bayonet saw is basically a saber saw that doesn't tilt and which has blades which hook around a set screw. I like the it because it has a sizeable platen; about 4x5" and 1/8" thick. Steel. I've never understood why they make saber saws with a match box size platen. I don't miss the tilt, don't recall ever usinig it on a saber saw. I use mine for all manner of things including cutting 4x8' sheets of ply wood into manageable pieces.
The sander is wonderful as a finish sander. It has a 1/2"+- thick felt pad and just the weight of the saw - and time - gets stuff flat and smooth. Yes, I have a ROS - and use it - but prefer this one most of the time.
Do you have favorites?
