  • My BS update

    I bought an old small metal cutting BS and have been slowly modifying/improving its operation.

    Blade cooling.
    Tank made from 6" PVC pipe holds 6.5 L of coolant


    A Small Aquarium pump drives the fluid around the circuit. Power for the pump comes from a socket from motor switch


    Mk II version of tank with fluid level window and click hose fittings for easy tank servicing.

    2) Handle upgrade to make adjustments easier

      3) Improved/easier adjustment on Vice including being able to bring vice jaws right up close to the blade for small pieces.



      Everything works good.

        You might want to make sure the pump is off the bottom of the tank by several inches and there is a baffle to direct incoming water away from the pump. The rotor on those pumps is a pretty strong magnet and is exposed to the fluid. Magnetic particles and magnets in tight tolerances do not go well together.

          Pump sits on a 1/2" thick piece of plastic above the bottom of the tank.
          2 REE magnets are located next to the outlet of the gutter and there's one at the bottom of the tank.
          I have a similar setup on my lathe (except the pump is about 3 times more powerful) which has been running successfully for about 12 months.
          Very little metal is evident on the magnet inside the tank.

            Damn, that is some really nice work! Simple, common parts, looks very effective. what more could you want? I love the vise adjustment! I may just go make a plate with a setscrew in it for that very perpose soon..

              Agree with Black Moons, well thought out use of basic materials,, thanks for posting this.

                Cheers Guys.

                I use PVC pipe for a lot of things. Here are a couple of other examples.

                The two painted containers are chainsaw mill auxiliary oil tanks - the deliver a drip of oil onto the chain near the nose of the bar. The non painted containers on the right are my welding rod storage containers. They are made of storm water pipe.

                  That's a really good idea putting the auxiliary oil tank on your chainsaw mill, I'm certainly going to steal that one. Nice work.

                      That's a very common thing to do on a chainsaw mill. On my big all aluminium mill I have an aluminium tank.

                        why do you cool after the cut?

                          Probably intended to wash chips from the blade before they're carried on around. Some larger saws have small rotating brushes for this duty.
                          .

                            dian the coolant after the cut is JUST in-case he put the blade on upside down
                            Some great ideas Bob, thanks for sharing.
