Excellent video and editing. However, you made the job much harder than it needs to be. The best reference on the subject is Jon Eakes book "Fine Tuning a Radial Arm Saw" that is available as an ebook on his website. He discusses the differences between different manufactuers, but the process is identical for all and doesn't require special tools. You also skipped a few steps such as getting the play out of the column. One critical error I see is that you have too much play in the carriage bearings. When properly adjusted it should take 5-8 pounds of pull to move the carriage and motor. This is because the saw has a tendency to pull itself through a crosscut and can climb on top of the stock you are cutting. Also, the table mounting brackets on your saw are attached with square nuts that lay flat against the flange on the inside of the base to keep them from spinning. A crescent wrench on the flange side bolt will gently lift the flange for a perfect fit. I like to adjust the table flanges before installing the table and use a feeler gauge to get the four corners of the outside flanges co-planar. I then adjust the center support by putting a straight edge between the two sides. I then drill holes next to the bolts and bolt them in place to keep them moving if someone pound on the table. It is difficult to build a perfectly flat laminated table but you can make one flat by securely bolting it to the supports. You can also use T-nuts and/or bolts to raise or lower the center. The Craftsman RAS manual explains this process. And last, just because your saw will take a 12" blade doesn't mean that it should be your everyday blade. For best results, you should use the smallest blade you need to make the cut because smaller blades have more power - especially for ripping.. Often missing on the 790 is a bumper that mounts on the rear of the motor arbor. It prevents you from cutting into the column if you are making a bevel cut with a 12" blade. Also frequently missing is the anti-kickback pawl that is essential when ripping. Most users at the Delphi Dewalt Radial Arm Saw Forum find that the Freud LU83R010: 10" Thin Kerf Combination Blade is the best all around blade for daily use. Seeing the care that you put into tuning up your leads me to believe that you will become an enthusiast. Have fun using it.

Thanks for the tips! I’ll definitely mention some of these in the next RAS focused video. I did purchase a return reel which pulls the carriage back to the home position - I didn’t want to overload the bearings too much. I got them just tight enough that there is zero play, but no more. My saw did come with the anti kickback pawl, but I am not going to do any ripping with this guy so it will sit in the drawer. The bumper is also present (I think).

Thanks for watching! In practice I’ve found that it loses the “super tune” pretty quickly after making any rough cuts. I’ve been using it mostly to rip long stock to width, and then I make the precision cuts on my table saw with a sled. Maybe someday I’ll find an extremely beefy 16” model with the turret design; I think those hold their settings a bit more robustly.

@@JimPudar Jim - I don't think the problem is necessarily with the saw losing its tuning. All radial arm saws have multiple moving parts and need "end play" for the parts to move. But unlike many late model saws, your DeWalt is built with very close tolerances. Even so, you still need to account for end play when tuning your saw and setting up for a cut. The most common complaint new users have is that saw doesn't cut a consistent 90 degree crosscut. This is usually a combination of failure to take into account end play during the tuning process and while using the saw. The column may have play, the carriage bearings may be too loose, the motor may not be locked in place and the locking lever for the arm may be too loose. For example, the arm locking lever should be tight enough so that it doesn't fall down on its own. Once the lever is lowered, there may still be a slight amount of play. You eliminate this by applying slight pressure to the arm in one direction (most users apply pressure to the right) as you seat the lever in place. You need to follow a similar procedure when you lock the motor by pushing the locking pin down and applying slight pressure while locking the lever in place. I see that you didn't check the column for play in your video. It seldom develops slack but it still needs to be checked. If you follow the tuning procedure in Eakes' book, your saw is build to stay in allignment provided you follow a set procedure every time you move the arm or motor to a different position.

One "improvement" you can add to your table system is to add a 1/4" layer of plywood or hardboard as a consumable surface. That will preserve the integrity of the table over time. Another improvement might be to remake the table in the "Mr Sawdust" fashion. Brian Weekly has a set of youtubes which detail the process (including how to handle the back table sections' thickness).

The only two stories of finger losses have been from table saws . I've had them and gave them away . Nice saw ❗

I love this and am happy to subscribe. Excellent presentation and some great work. I have a similar vintage 10" version that was handed down to me and I went through a lot of the same processes. I also built a "Mr. Sawdust" style table for it that I'm pleased with. You can't beat a RAS for crosscut capacity which is what I mostly use it for. I found the same deflection in the arm that you did. In the end I don't worry about it too much. I use the saw for 'close' cuts and will true more important dimensions on my table saw sled. If you're looking for other tips on setup I found Brian Weekley's channel and videos to be super helpful. The dust collection style that Tommy Tompkins built seems to work best of the versions I've tried. I embeded some threaded inserts into the chute so that I can take it off for angle cuts. Cheers to breathing new life into a great old tool and thanks for taking us along with you.

@JimPudar

Hi, I wanted this to be a very flat assembly table in addition to being an MFT. It’s a torsion box with less than the typical number of inner beams because the beams interfere with the Festool clamps. Overall I’ve been very pleased with it, but I don’t normally use any MFT accessories which must be screwed down from under the table. I don’t have access to the underside of the top with this arrangement. I’ll admit it’s a pain when I drop a screw in one of the holes :D I don’t think a table this big would work well without some kind of structure supporting the middle as the MDF would bend if it were just a single layer.

So jealous! A 790! I have never found one of those. Dang. I had to get a Black and Decker T1530 version of the 790, which was made in 1969 and it's not as cool because it's called a "Black and Decker" on the model tag. I've never had anyone to help me with anything, so I loaded mine up myself into my work van by taking it apart, and carrying the arm and motor separately. The only thing stopping me from setting it up is that it's so difficult to move once it's all assembled. P.S., don't make jokes about not being a machinist. You're the most meticulous person I've ever seen on KZitem, and I've watched every radial arm saw video that exists on KZitem. I've never heard of "Way Oil" before, or seen anyone make adjustment screws for the table. Nor have I heard of anyone actually replacing the carriage bearings or even make a mention about how smooth or coarse they are. As far as I can tell, the reason the Craftsman saws are inferior is only because of the VERY coarse sloppy bearings they use on the carriage, and not because they are a poor design (they are a good design overall).

@@JimPudar Are you still using this 790 saw? I am still debating whether I should keep my version of the 12" saw with the 17 amp motor. I am actually really afraid of the 17 amp motor on a radial arm saw. I do daily ripping of boards, including old reclaimed hardwood boards, on my Dewalt 9" saws, and also a Craftsman 10 amp radial arm saw. With the small 10 amp saws, they stall when the blade binds, and they don't kickback the board. I'm extremely nervous about using a 17 amp motor, because it has no margin for error. Are you using the saw for daily shop functions, or is it more of a novelty item? The 12" saws are so big, I'm not sure that I am brave enough to use it.

You can find that here: bealltool.com/products/threading/countersink.php I find that it works much better than any multi-flute countersink I’ve tried. The chamfers it leaves are extremely clean and uniform even when using a hand drill. The major downside is that there’s no depth stop, but you can work around that by feel or with a drill press depth gauge. I also really like the carbide countersinks from Amana Tools, but I use those more when I’m trying to make 20+ identical countersunk holes that all look perfectly uniform. The Beall one is really cool because it’s big enough that you can countersink very large holes with it just as easily as tiny ones.

The heel was actually dead on in both directions when I measured it after putting the motor back on. The cut quality is seriously amazing, it’s better than my Festool tracksaw! I did soak the original bearings in simple green and tried to get some grease in. I got them working far better than they came to me, but they still felt a little crunchy. The new ones are just phenomenal, I’m super glad I made the investment! After splurging on the blade and stiffener new bearings just made a lot of sense.
