  • Sawing Aluminum with tablesaw

    I seen a post on here about a month ago where someone was talking about cutting aluminum with a carbide tipped tablesaw. He said it worked very well if the blade was waxed. Okay---semi-dumb question---what kind of wax? I have liquid car wax, I have pastewax for the hardwood floors, and I have some wax candles. Which would be the best to use for waxing the blade?---Brian

    Paste wax on the blade and candle wax in the ears if you don't have hearing protectors. Cutting aluminum with a table saw will make such a racket it will scare anyone within a block radius and can damage your hearing.

      Brian, when making my CNC router, I cut 1" ali plate with my makita drop-saw.
      Use candle wax. You'll be fine.
      If thin ali, just a squirt of WD40 or kero.

        Bee's wax is the ultimate aluminum lube. Got any bee's wax candles?

          I have a spare koolmist sprayer that I mounted under the table in plane with the blade. Works well. Keeps the blade cool and keeps it from warping from the heat. I use a 9" hollow ground HSS blade I picked up from boeing. I think it has a 1/16" kerf.

            table saw

            I frequently use my table saw to cut aluminum and find a large plastic bag and cover myself with it during cutting. If I don't cuttings get in my hair and down my neck.Safety glasses and face shield just don't do it. Peter
            The difficult done right away. the impossible takes a little time.

              in the absence of beeswax, a bar of soap will do just as well

                            Enough of this funny Bees-ness!!! I just cut a peice of 5/8" aluminum with my ancient flea market table saw, and it cut beautifully. I waxed up the blade with some Johnsons paste wax that normally gets used on hardwood floors. I am supposed to be working an engineering contract right now, but I'm hung up waiting for a call back from my customer, so I'm playing Mister Machinist this afternoon. I roughed out a 3 1/2" circle from the 5/8" aluminum plate and machined up a small jig to hold it for turning, and I have turned it to finish size on the lathe.---- and now I have the hub for my water-wheel. I was going to use 1" plate, but the 5/8 was here in my scrap bin, and was free!!!

                              Modern day candles are made out of some wierd stuff that is not really wax. I mean, it is, but it sure is crummy wax.
                              When I saw aluminum, or rout it with my big 3 hp hitachi router, I use a wax stick that is made for the purpose.
                              I know its cheating to use the right stuff, rather than catching my own beaver and making lard from its tail fat, and then climbing a tree barefoot in a loincloth to get a beehive, and mixing the two in an old oil drum out back over a pallet wood and used motor oil fire-

                              but it only cost about ten bucks, and it comes in a cardboard tube kinda like a grease tube, and it is exactly the right stuff- solid at room temp, but soft enough to rub on the blade.

                              A decent industrial supplier will have it, I am sure MSC/Enco/McMaster all carry it too.

                              One stick will last you a long long time- I think I bought mine in the 80's.
