Delta 33-830 RAS

 

  The saw's dual voltage motor comes wired for 120-volt operation out of the box but can be switched to 240 volts if you choose. Also, there is a reset overload relay button built in to the top of the motor that will pop out if you were ever to overload the saw. To reset it just push the button back down. I've never had to rely on this protection so I'm just quoting from the manual.

  The handle has a nice feel to is and looks to be quite comfortable for hands small and large. The power switch is a flip lever that you activate with your thumb (if you're right handed that is - southpaws will have to figure out another way to operate the switch with their left hand).


Setting the heel.

  You've already adjusted the track arm so that it tracks in a straight line along it's entire length of travel, but you're going to have to check the "heel" of the motor head/blade to see that it is perfectly parallel with the carpenter's square which is set up against the fence. To do so you'll need to set up a temporary fence that is taller than the stock fence and set the carpenter's square atop some blocks of equal height in order to get the square's straight edge up near the center line of the blade.
 

Heel Adjust.

The heel adjust...

  When I checked mine the blade was off quite a bit, twisted clockwise until the rear of the blade was about 1/8" off from the front of the blade. Again, the Delta people made it fairly simple to make the proper adjustments to eliminate this misalignment.

  In the image to the left you can see that the heel has been adjusted so that the blade is perfectly parallel to the straight edge. Be sure you have the straight edge against the body of the blade all the way across, and not up against a tooth on one end or the other to throw off the accuracy of your adjustments!
 


Just about there...

  There are a few other minor adjustments you can make to complete the setup of the saw. One is to adjust the tension of the track arm slide mechanism. You want it to slide easily but not so much that it will glide with only a little push. You'll want it to move only when you're actually applying pressure in one direction or the other. You can also adjust the track arm-locking lever (not the ring) to any position you want to make it more accessible. All this is detailed in the manual.

  There is also a locking lever for the head so it can be firmly positioned anywhere along the length of the track arm. This is useful for when you rotate the head 90 degrees for ripping boards. You'll want to be very cautious when ripping because unlike a table saw which spins such that the board is being forced down towards the table and back at you, the RAS blade is trying to lift the material off the table and away from you if you're feeding from the left side. You don't want to be hanging onto your work piece when it suddenly decides to take off! Just be sure you are aware of the directional forces when you are ripping!

Blade Guard.
The blade guard.

  The blade guard provides good coverage of the blade and is designed to help prevent what we mentioned above - provided you have it set up correctly. Be sure to take the time to make the proper adjustments whenever you work with a different stock thickness.

  One thing I don't like about the saw is the dust collection port atop the blade guard. I hooked my dust collector hose to it and it didn't pull hardly any dust away; rather it all goes screaming out the back of the saw off the table. I made an aluminum box to mount in the path of the dust with a port for my dust collector hose and it helped 100%! If you wanted to, you could probably just clamp the hose from your dust collector or shop vac to the table right behind the blade without need for any type of special boxes.


Final Impressions

  Delta calls this a "Professional" RAS, and when I look at the construction, the gauge and quality of the materials used, and the quality of the finish, I agree that it deserves the title. My saw will remain in my shop in the position I set it in but if you were a contractor or carpenter who needed a RAS on various job sites, this saw is heavy duty enough to handle the rigors of being hauled around in the back of a truck and getting generally banged around on at the construction site. You might have to make some minor adjustments to the table to insure it is level but everything else should hold tight.

  Accuracy should never be a problem with this saw once you have it set up and tuned up. One of the Craftsmans I had had a terribly wobbly feel to the head as it slid down the length of the track arm; you could actually grab the handle and twist the head back and forth enough that you could cut dados with a regular cross-cutting blade! I made all the adjustments I could to the saw but never felt that it was quite right. The ball bearing slide mechanism on the Delta has a great feel to it and there is absolutely no side-to-side play at all no matter how hard you twist on the handle.

  The same tolerances were maintained throughout the saw's construction, which means you can be confident using it for any type of cutting - even the most delicate work involved in making fine furniture! I know the RAS has a reputation of being a "construction" tool; one that is best suited on the job site whacking at 2 x 4's all day, but a saw of this quality will be a welcome addition to even the finest furniture maker's shop.

  We probably all know at least a few woodworkers who own a RAS but not a table saw, and sure, you can do just about anything on a RAS that you can on a table saw. But frankly, I don't really like ripping that much on the RAS, and there are other tasks that are better performed on the table saw too. But there are things the RAS is far better at than a table saw, so why not own them both? You'd then have a full compliment of tools for ripping and crosscutting! But you know what? I've already used my RAS for a ripping job. I had my table saw set up to rip the sides of a cornet cabinet at 67.5 degrees, and, needing a couple of braces for another side job, I didn't want to mess with setting the table saw blade back to 90 when I still had a lot of cutting on the angle left to do. It took me a few minutes to finally look over my shoulder at the RAS, but when I did I know I grinned ear-to-ear when I realized how much more versatile my shop is with the addition of the RAS.

  Costing right at $700 US, the saw is priced about the same as a contractor's table saw. When you consider the cost of a new power compound miter saw, especially one of the really cool sliding types, you're talking at least half that price, and the RAS can do so much more for you. You'll never have the cutting capacity with a miter saw, and you can't cut dados with a miter saw - sliding or not! That's one of the things I will use this saw for the most. Dados cut across long boards can be very dangerous to cut on a table saw, and there is so much setup time involved with using a router and straight edges. Just mount your Super Dado blades to the RAS, raise it to the required height and you're ready to cut dados all day! Great for lap joints too!

  The blade that comes with the saw is not worth the metal it is stamped from, and the Delta rep gave me a Delta 60 tooth carbide tipped blade and asked me to use it for the review. If you buy this saw, I would ask them to do the same for you - throw in the better blade! (Don't ask the retailer to cover this cost, ask that Delta does!) Blade changes are relatively easy because the blade guard is so well designed. Loosen one knob and it's ready to slide out of the way. The guard is made with a kind of tongue that slips over a groove on the motor head. The two mate up very well and the bolt and knob assembly are beefy enough to really clamp the guard in place securely. The anti-kickback device on the guard is well designed and constructed. Just remember to take the time to adjust it for the material you're cutting or it won't do you any good at all!

  All the locking levers are heavy duty and feel like they can take a lot of oomph. Some people still have the idea that you have to tighten something as tight as humanly possible and then go another quarter turn, but when you lock down the miter lock or the motor head locking levers, you get good feedback that lets you know when they're tight enough. I also like the elevating handle. It doesn't take Steve Austin to crank the saw up or down and it's a fine enough thread that you can easily make vertical adjustments of 1/64" or less. The 12" Craftsman I had seemed like it moved 1/4" by just looking at the crank! It was really tough to make that last little adjustment to get the blade height exactly where you wanted it. Not so with the Delta.

  I guess the only real complaint I have is the dust collection port. It just doesn't seem to work for me. Maybe I don't have enough CFMs with my dust collector to pull the sawdust out but I don't think so. There's so much velocity behind the dust as it flies off the bottom of the blade that it wants to go straight out the back. You can make some type of collection device to place directly behind the blade to solve this problem like I did or simply enjoy watching a huge cone of saw dust grow off the wall behind your saw! :-)

  Lastly I want to thank Coleman Fourshee and the great folks at Klingspor's Woodworking Shop for supplying me with this great saw. There aren't really that many mail order tool companies that carry the RASs but Klingspor's has the Delta 33-830 10" Radial Arm Saw in stock right now. If you need a RAS with even larger cutting capacity, they also stock the Delta 33-890 12" Radial Arm Saw, and can ship either one to you tomorrow! At $699.95 for the 33-830, and $1659.95 for the 33-890, you'll not find a better price, nor will you find a better Radial Arm Saw for any price!
