- I am not sure that all of the books would always agree with every
- thing below, but this is based on 20 years experience and I have all
- my fingers:-). And yes, Sears RAS were built much better then. I still
- use the same one. I just finished helping a friend set up his newer Dewalt
- I wouldnt trade.
-
- On fence placement: I place my fence so that the saw will park behind it
- in its furthest back position, and the blade will be completely behind the
- fence. Reason is so when you place the work on the table and back against the
- fence it isnt touching the blade. This is of course for cross cutting.
- The fence doesnt need to be much higher than an inch or 11/2" for normal work,
- You also need to do some preparation to your table top. I fastened a piece
- of 1/4" particle board to it being very carful to nail/screw in places that
- the blade wouldnt cut. This is difficult and certainly somthing like contact
- cement would be much better, but there will come a time when you want to change
- this overlay when it gets all beat up. Whether you put an overlay on or not,
- when you have the saw set and adjusted( squared, heel set,etc -best done with
- help of a manual) run the blade the full lenth of the cut and about 1/8"
- deep so the teeth can project below the work. As time goes by this will get
- deeper, that is just the way things are.
- Also turn the saw to the ripping position-blade inside first- and set to the
- same 1/8 depth . Cut a shallow scoop across the table the full width of
- the cut. Turn the blade to the blade out position and finish to the edge
- of the table.
- Now set the saw to the 45 degree settings first on one side of 90 then the
- other and cut thru the fence. Now you are pretty much prepared.
-
- On the topic of pushing vs pulling:
- I normally pull the saw toward me thru the work. That way the saw rotation
- is forcing the work down against the table top and back against the fence.
- I have read that pushing the saw back toward the back of the table and thru
- the work makes for a smoother cut. I am not sure I can explain the logic of
- that and it seems that it would be more likely to tear the edge as the saw
- enters the work spinning upwards. It also seems to me to be a lot less safe.
-
- Ripping: Whole new ballgame. Anytinme I have the saw grab work and throw it
- around or pull it in and jamb it has been while ripping. Unfortunately I
- dont have sufficient room to set up and run only one way so I have had
- more than enough opportunity to decide which way is best. Given choice I would
- always feed the board from the "back" of the saw -that is the side where
- the teeth are spinning toward you and up. Reaason is that I find it very
- difficult to prevent the saw from grabbing the work and running up on it
- when feeding from the other side. I use the hold down on the back of the
- guard to keep the wood from being pushed up. I guess on the whole I would
- rather have a piece of wood flung at me than my hand pulled into the blade.
- Fortunately taking some care can prevent either from happening.
-
- On the whole I wouldnt trade My RAS for any other piece of equipment. I
- cannot emphasize the importance of setting up everything very carefully
- and checking often. When my saw is set right, I can cut mitres almost as
- good as a cut off saw, and I can "sneak" up to a cut off line so close
- that if the line is a knife cut, I can split it at the bottom of the V.
- Takes a good and sharpe blade too. Do get a manual, if you cannot get
- a Sears manual, and maybe even if you can, get one of the good RAS books
- from your nearest good wood working store. I seem to recall seeing one called
- "how to get the most out of your RAS" or similiar.
-
- Good luck, take your time and go careful. You will get more at home with the
- machine and will be able to do more, faster, but never forget to concentrate
- on being careful.
