Strictly for Dado your Craftsman will probably work fine. Assuming you are
purchasing a 10" RAS, buy a quality 8" dado, some will say use only a 6" dado, but on the RAS the 8" works as a flywheel to keep up the motor speed. You might consider buying a DeWalt instead so that you can use your RAS for other operations too. The DeWalt alignment system is the best in the business and doesn't come out of alignment easily. -- Rumpty Radial Arm Saw Forum: http://forums.delphiforums.com/woodbutcher/start - - - - - - - - - - - - - - - - - - - - - "Keith" wrote in message om...

Stick with the 8" dado, the motor housing resticts the depth of cut too much. With a 6" dado you will be able to do very shallow cuts. i use a 8" dado in mine with no problem. IIRC I can cut about 1-1/4"+ in depth with a 8" dado in my Crapsman saw. a 6" would get that down to just 1/4"+ in depth. Good enough for 90% of the cuts, but deep dados will be out of the question.

IME, crosscutting dados with my Craftsman RAS is a bit tough because the
blades really grab the wood and the carriage lurches forward. While there are RAS blades made to help avoid this when simply cutting, I do not know of a dado blade designed for the RAS. Forrest make a great dado blade that works well on the RAS. carriage lurches forward The roller head bearings might be too loose and require adjustment. You need to hold onto the motor with some positive control. -- Rumpty Radial Arm Saw Forum: http://forums.delphiforums.com/woodbutcher/start - - - - - - - - - - - - - - - - - - - - - "igor" wrote in message ...

This you may know, as it applies to RAS in general: If the wood does not sit flat on the TS when you cut a dado, the dado will be too shallow -- and you can cut it again in the same piece of wood. Of course on the RAS if the wood is not flat the dado is cut too deep. For example, if you are ripping a dado on a long piece with the RAS and the wood is not supported well, it can arch upwards along the way and you cut too deep. For that matter, even crosscutting in a long piece can cause problems, but they are a bit easier to catch before you cut. So, you have to be plan accordingly to ensure that the wood is flat to the table. All that being said, it can be much easier to cross-cut a bunch of dados in 8' long pieces using an RAS than a TS.

You need to hold onto the motor with some positive control. Correst, and if the saw is adjusted properly, there will be some smooth resistance to the motor moving on the arm. In addition, if the OP is considering a new Craftsman RAS, it has a motorized cable attached to the motor that controls the feed rate and prevents the "lurching". -Doug |

If that's all you are going to use it for, get a used one, there's
plenty of them out there. I have one from the 70's and have used it for dado work in the past and its worked fine, but since they fall out of alignment fairly easily, I have to re-square and realign it each time. If you can find an old Dewalt from the 50's in good shape(prior to the AMF acquisition) those are really sweet machines. Mutt (Keith) wrote in message . com...

Hi Keith,
I bought a Craftsman RAS about 7-8 years ago. I also liked the idea of being able to make a mark where you want a dado, then actually seeing the blade line up with the mark - or run a narrow dado & creep up to the width you need. I also considered some other brands, but they were too much $ for me at the time. Also, I got a great deal around the holidays by combining sales & coupons - I think it was around $450 or so. I added their dust collection (big gulp like) set-up and this grabs 95% of the sawdust. When I assembled it, I was sort of surprised with how thick the instruction book was - these saws have a lot of adjustments. It is the only tool I have where I keep this book hanging next to the saw for reference. Typically, I have to tweak it every 6 months or so. I recently got a Freud 508 dado (8 inch) as an upgrade from an adjustable dado that I used for years. I had/have no trouble using either in the saw. In summary, I think it is a pretty decent machine and worth having in the shop. Lou In article , Keith wrote: I am considering buying a Craftsman RAS for mostly dado work.

For the use you describe it would be fine. The best thing about the
Craftsman RAS is there are thousands of them on the used market. Barely a week goes by, in our area, that one doesn't show up in the classifieds. Occasionally you can pick one up, with a load of accessories, for $150 - $200. "Keith" wrote in message om... I am considering buying a Craftsman RAS for mostly dado work.

Sorry, I am looking at a Brand New Craftsman RAS. There only seems to
be one model on the Sears website. I also looked at the Delta 10" RAS, but it received some bad reviews and the design makes it tougher to use. The height adjustment is at the back of the saw instead of being in the front. I would need to have this saw backed up to a wall in my shop setup and changing height settings would be a pain. I currently have a Jet table saw. I do a lot of furniture and bookcase type work. I find it takes so much time to switch from the regular setup to the dado and back. I also found similar problems with my router table that is mounted to my table saw. I feel like I'm forever switching setups. I would like to have one of the Delta 12" RAS's but I can't justify the cost. |

I have a Vermont American dado blade set that I use in my Craftsman RAS; it
will try to self-propel if you don't keep control, but it isn't too hard to control, at least on things like plywood. A hardwood, like oak, might be more trouble, but I usually use a router on such. One complaint about the RAS is that the table isn't quite level. I would like a dado to be the same depth at each end, another reason to use a router. Steve "Rumpty" wrote in message ...

One complaint about the RAS is that the table isn't quite level. I would
like a dado to be the same depth at each end, another reason to use a router. All tables can be adjusted so they are flat. Buy the Eakes book that shows alignment for the Craftsman, Delta and DeWalt RAS's. Better yet, replace the table with a 2 ply steel reinforced table like the Mr. Sawdust style table.

So why have RAS's fallen so much out of favor? For cross cutting wood, it
seems so much easier to use than a table saw and I have the added bonus of being able to put a sanding drum in the chuck on the back side. It just seems so much easier to move the blade instead of some 10 ft long piece of wood. "RonB" wrote in message news:x74nd.66598$EZ.63615@okepread07... For the use you describe it would be fine.

There are more concerns. Ripping hardwood on the RAS is about the scariest
thing I do and I avoid it when I can. I also made an auxilliary fence for mine. It clamps on the regular fence at right angles so I can rip by moving the blade on pieces up to about 30" long (by flipping the piece and cutting from each end). It sets up pretty quickly, but I have to square it every time - keep a carpenters square nearby. An advantage of the RAS is space. I don't have room for a table saw that sits in the middle of the floor and needs room for infeed and outfeed. My RAS sits quietly along the wall and leaves room for the car.

In addition to what Doug mentions, correct alignment, proper blade (Forrest
WW1 with TCP profile) and addition of a long rip fence makes ripping a breeze all day long.

Thanks for the info... my Dad recently gave me his old RAS and I find myself
using it much more than dragging out the 10" tablesaw I bought a while back (which I'm generally happy with but I don't have space to keep it set up all the time). I just called and ordered the safety kit someone else mentioned in this thread. I'll have to check out this book as well.

Almost all of the scare posts I've seen about RAS' wind up with the user having been so frightened (unwarrantedly so) by the teeth moving toward them that they fed the wood from the other side (climb cutting) which is at least 20, maybe 50 times more dangerous. I, too, find it no problem...even without holddowns, although I always used the splitter and anti-kickback device (all in one on my saw). - - LRod Master Woodbutcher and seasoned termite Shamelessly whoring my website since 1999 http://www.woodbutcher.net |

I can't understand why TS teeth moving towards the operator are OK, but RAS teeth are scary? Feeding with the rotation isn't just scary, something or someone is going to be severely damaged! The holddown I was referring to is the one on the rear of the blade guard. On my old PowrKraft RAS, it was adjusted by rotating the guard until the holddown was just above the workpiece and then locking the guard in place. On the current Craftsman RAS, the holddown on the rear of the guard has a lock knob that allows it to be adjusted just above the workpiece and locked - the guard itself doesn't move. In either case, the holddown prevents the workpiece from being lifted by the rising teeth when starting the rip as the workpiece is fed from what is the rear of the guard for a crosscut operation. -Doug -Doug |

It had identical markings to the blade on the RAS in the store. Neutral to negative hook and feed-control shoulders (look like depth gages on chainsaw blades.) I wonder if Sears is going to let the RAS go the way of the dinosaur. Keep in mind that Sears was asking about $500-$600 for the RAS and between $150-250 for most 10"-12" compound miter saws. The CMSs' can do 90% of the cuts the I usually do on the RAS. My Dad taught me how to set up the RAS. The 10% of the cuts it can do which the CMSs' can't are rather spectacular in their utility and shear terror. The RAS is dangerous in ways the TS just isn't (climb & cross cut thumb) and completely docile in way the TS is a nightmare (it just doesn't throw things at you and the temptation to shove your hand into the blade on the cut isn't there). I have ripped 8' sheet goods on the RAS before. It presents a different set of issues to overcome that the TS. The fence is longer, (probably truer than the old craftsman TS fence) and the table is aligned along the cutting axis on the RAS. The old 60 tooth combo blade I had on the RAS had WAY too much hook for safety. I caught it climbing more often that I cared for. Back on the table saw it goes. There are many small projects where the RAS is just tons more handy to me than the TS is. This could be because the TS is on a roller base and usually stays tucked below the right side of the RAS. Cutting 12' stock on the RAS is a no brainer. Cutting it on the cross cut sled on the TS takes a day of planning ahead. I've had the cross cut sled half way across the TS when it decided to stop sliding. That's an Aw **** sort of moment. The RAS never stops sliding :-) -- Dana Miller |

Yes, it does have to be adjusted for the thickness of the workpiece for rip operations. Not a big problem and taking around 5 seconds. And, the workpiece is under the hold down *before* it comes in contact with the blade. Do you adjust the blade height on the TS depending on the thickness of the workpiece? I do. Is a RAS an "untrustworthy" lump of iron? -Doug |

The "safety" of the RAS during ripping IMO depends more on the correct
blade than on the guard nose being positioned properly as well as the kickback pawl. The Forrest WW1 blade with the TCP profile really performs in the rip. It has a positive hook which gives you decent feed rates. Also correct ripping procedures are important too, such as using a push board when ripping narrow pieces etc. -- Rumpty Radial Arm Saw Forum: http://forums.delphiforums.com/woodbutcher/start - - - - - - - - - - - - - - - - - - - - - "Andy Dingley" wrote in message ...

TS teeth move forwards and down, holding the wood down onto the table. RAS teeth move forwards and up, lifting the wood off the table. You're reliant on the additional hold downs, not just a big trustworthy lump of iron. |

That's just silly - maybe the gullet root should be that low, but setting it on the tooth tip isn't going to clear the chips properly. So why set the blade low ? It reduces the Scary Whirling Death Blade, but the best ways to stop that being a problem are to keep your fingers out, and to use a crown guard. In terms of cutting performance, it's a bad idea on every count. Why set the blade high ? - because it reduces kickback risk. This is good - I can't "keep my hands away" from kickback, and I can't really build a guard against it. And what about non through and dado cuts? Oh, that's right - you aren't allowed to use those dangerous devices. Of course we're allowed to do them. Here in Evil Pinko Europe (motto: a uniformed nanny in every nursery) we celebrated the fall of the Berlin Wall by performing dado cuts through old statues of Stalin. Why do people keep thinking that Europeans aren't "allowed" dado heads? On the whole I like our HSE. I can think of some really stupid rules (Article P) coming in on wiring from other government agencies, but the industrial safety people offer good advice and have never put forward any rule or requirement that I've ever seen as pointless or excessive. -- Smert' spamionam |

That's just silly - maybe the gullet root should be that low, but setting it on the tooth tip isn't going to clear the chips properly. That's really silly. Are you suggesting the chips that are in the gullets must somehow be carried below the table, around and back up before they can be expelled over the top of the workpiece at the operator? So why set the blade low ? It reduces the Scary Whirling Death Blade, but the best ways to stop that being a problem are to keep your fingers out, and to use a crown guard.

This is good - I can't "keep my hands away" from kickback, and I can't really build a guard against it. The main cause of kickback is the rear of the blade lifting the workpiece, and the higher the blade, the more vertical the rear blade motion. Sorry, I don't buy your argument.

That's a risk, but it's a risk that's easy to deal with. Over the width of the blade it's balanced front and back, so the force your hold-down needs to provide is much less than it would to resist the unbalanced forward forces from a blade that's rubbing on the upper portion of the blade. It's also notable that rear-blade lifting doesn't cause kickback itself, what it causes is lifting the blade into contact with the area that does then kick it (admittedly by this point the blade will have increased any skewing it might have, which also makes the drag worse). I'd like to keep my timber away as much as possible from the really dangerous area - the patch near the top of the blade where the forward forces are largest. If you have a kickback near-miss on a high blade, it's _very_ evident that the blade starts to lift the timber with a small force, then may (if you're unlucky) push it forwards with a much greater force. This is another reason why low splitters aren't much use - if the timber does lift off them, the timber closes up and suddenly grabs. I can feel a small amount of drag before it's a problem and just hold the timber down or kill the saw, but with a sudden impulse it's going to fly before I notice. I've had a bad week for kickbacks to be honest - it's near freezing in the workshop and clearly the saw table has contracted. My fence is now dragging and the tail end is going out of square unless I'm careful about the setup. -- Smert' spamionam |
