Just to put in my two cents worth here, I'd suggest that anyone considering using a radial arm saw should purchase a copy of Master the Radial Arm Saw by the late Wally Kunkel, aka Mr. Sawdust. You can get a preview of the book and/or purchase it at
https://mrsawdust.com/master-the-radial-arm-saw/overview. The author started out as an advertising copywriter who was assigned the DeWalt account. He was then an amateur woodworker using one of the early Shopsmith machines. He fell in love with the saw, sold them for decades, and established a woodworking school in the process. The book details how to set up a radial arm saw and how to use it safely. It's written specifically for DeWalt saws, but the first thing I noticed on reading it is that the setup and calibration instructions are nearly word for word the same as the ones in the owner's manual for the Craftsman/Emerson RAS sold by Sears and Rigid. I suspect they cribbed them directly from Kunkel's book. The secret to setting one up, btw, is a bit counterintuitive if you're used to a table saw. Step one is making a
really flat table. Then you adjust the plane of the table to be exactly parallel to the plane of movement of the saw carriage on its track. Then you adjust for blade heel, squareness to the fence and so on.
I've owned and used both radial arm and table saws for decades, and each type has its strength, weaknesses, and hazards. The RAS
looks scary, mainly because the spinning blade is right out there where you can see it. That's also a benefit, because it's out in plain sight, not lurking underneath your workpiece with nothing showing but a blur of teeth poking up from the cut as on a table saw. Either type of saw will be dangerous if you don't take the time to make sure they're properly adjusted and have splitters and anti-kickback devices in place. Blade choice is critical, too. A blade with an aggressive rake to the teeth can bite into the workpiece and self-feed on a radial arm saw. That's disconcerting, but so is having a table saw throw your workpiece through the wall behind you, assuming you weren't stupid enough to be standing in line with the blade while feeding it in.
The radial arm saws, even more than table saws, have suffered from being made cheaper over the years. In particular, the bases on the newer ones are made of lightweight materials, and the table can be knocked out of alignment easily. The tables themselves, which used to be made of either rock maple or straight-grain fir, usually 5/4 or better, devolved into MDF and then into cheaper chipboard, and they're rarely found without serious warping. Kunkel's book tells how to make a proper one and flatly says that if you aren't going to do that, don't bother reading any further.
I currently have a 30-year-old Craftsman 10" table saw, the old one with the cast-iron wings, with a few upgrades like a better fence and a link belt, a Dewalt MBF 9" radial arm saw from the early 1950s, and I've just acquired a 10-inch Rockwell Delta turret radial arm saw only slightly newer. I previously had an older Sears Craftsman 10" radial arm saw. I gave that to my brother-in-law, foolishly thinking that I could do everything with a good miter saw and my table saw. Wrong! There are quite a few crosscutting tasks that are unhandy on a table saw, and even a good dual-angle compound miter saw isn't remotely as versatile as a radial arm saw.
