    Haven't run a RA saw much eh ?
    Rather you just keep warning people so much so they become scared as much as you are.
    ---------------------------
    I used to run one for an employer, and did them cross cut wise, and yes, as a normal climb cut, stacked up 3/4" of cutters.

    Make sure your machine is aligned properly so as not to grab.

    I cut dados with mine, no reason you can't put a clamp on the wood so both hands on the saw. never ripped a dado though, wouldn't dream of cutting metal in a chop saw without a clamp why would I do it on a wood saw that has a high tendency to grab? its nice to be able to see your cut marks

    I understand the caution, and I have my share of butt pucker moments with a RAS, but...


    This door and three more exactly like were made almost entirely on a RAS, half lap joints on the panel corners, frames notch framed.
    Oh and the deck rail behind all the uprights were notched for the rails, something like 30 of them.
    And most of that work was done by a 'real' carpenter with little experience on a RAS
    And the saw is a Delta 9 inch.

    Sears had at one time a variable dado blade that wobbled.

    Cut like standard blade so tooth bite small so these can do a dado but still it can get aggressive so good grip a must and verify where all body parts are located before starting cut.

    A sacrificial leading board may help.

    Or....you could think ahead of time, pull the saw OUT, apply the board to the fence, and conventional cut instead of climb cut.
    If you find you have tear out problems, a scrap of cheap Masonite on top should doo nicely.

    Yes you can use a dado set but it is best to do it in multiple passes. A neighbor did it many times on stock that was unwieldy on the table saw.

    The main thing to remember is that even if the hand holding the stock is out of the way now there are situations where vibration can make the stock slide toward the blade and pull your hand with it. Work safe, start cautiously until you are familiar with the tool and use clamps and guide blocks as much as possible.

    A RAS is the most dangerous tool known to mankind, right after the whirly-burr, that is........

    An empty gasolene tanker is the most dangerous vehicle out there on the
    "superslab".

    a RAS not so much. Only if your a ignorant Newbie that can't seem to respect tools.

    A few chuckle worthy comments for sure. Fwiw and yes none of this will ever make me a highly skilled RA saw operator. But I've been running everything from dinky little forklifts to the modern rope and hydraulic mining shovels and pretty much everything in between for the last 40 plus years. Anyone not smart enough to prevent mother natures natural selection then your a job hazard and you can get dead real quick in those jobs. If I do decide to attempt this? Not removing anything I was born with in the process will be a high priority. I've also been operating lathes and mills for just about as long at the home shop level and so far I can still count all 10 digits with both eyes. :-) Getting proper answers from professionals is why I asked here and not on any of the more hobby level wood butcher forums where sometimes a high post count gets confused with actually knowing anything you can trust. My sincere thanks to all who have helped.

    Minor nits....

    What Dad had done.. as he departed the role of Post Engineer & Deputy Post Commander, Newport News Port of Embarcation.. was purchase a BIG DeWalt 3-phase RAS that had been surplused out of the pallet shop as the Korean War was wound down.

    As a kid, I recall that paint and all it looked as if it had never made a single cut. And it might not have.

    He hauled that to Pittsburgh in a utility trailer and traded it to a local lumberyard for the price of a brand-new and smaller single-phase DeWalt he may as well have been trying to raise pups with, he came to love it so much.

    Even that one was new 1954, nearly all cast-iron, and heavier built column, arm, rollers, and such than any I've seen since, similar size, at "Big Box" and such-like outlets. The bigger one he traded was larger even than those HD and Lowes have where they cut timber for customers.

    A "Port of Embarcation" shipped armoured vehicles, railway locomotives, and such by ship, so their need of timber & grillage had been scaled accordingly.

    As with generating puppies.. or "whatever"..

    Wise to adjust your performance expectations according to the mass of yourRAS!

    ^^^ Which is why I’d love to have a Northfield Unipoint. Fact I don’t have enough big work for it and no space gets in the way of my fantasy.

    Say it again, louder, ISTR a PM member near me has a workalike - Monarch was it?
    He made a repair to a more cosmetic than essential casting crack, and it was good to go.

    One can pull the saw out, feed in the material, turn on the saw and push it back while making the cut. Do this anytime you don't want the saw to get in a hurry. We cut aluminum sheet and bar this way all the time with the 12 inch dewalt, the tin one not the heavy duty cast one.

    Disclosure:

    I do that with an El Cheapo "Kobalt" sliding compound mitre "saw shaped object".
    The old rusty one that lives outdoors. Not the cleaner new one.

    My Kasto is reserved for metal. Not shiney-wood.

    Made a sideboard for one of the kids beds that literally broke in half since it was veneered particle board
    Then I realized the drop would replace a lost fixed jaw on my under bench vise, but it needed to be ripped

    Still have all my appendages

    Maybe I will go adjust my overhead door spring now....
