  • Excalibur Ex30 - rattling?

    Hi All,

    I'm back on the saw properly at last.

    So as you guessed, it's the Excalibur Ex30, and a rattle has developed - or has it? I'm sure there's a new ticking noise at the blade end, and that it's been intermittent, but now is permanent. It's not loud. I use the saw at 1/4 speed.

    Am I imagining it? I can't find any info on this. I've oiled the bearings.

    Any thoughts or experiences or knowledge on this?

    Many thanks for anything.

    Karsten.

    Had a strange rattle in my EX16 yesterday. Traced it to something simple, the table had two loose screws. Tightened the screws and is as good as new. My advice is to tighten everything if you haven't already. Good luck, Doug

      We need to oil something on the ex's? I have the 21". I had a similar noise develop on my 21" and it too was the bolts holding the table had come loose. I used some blue loctite and tightened things down and all is well.

        I find that I get a small noise every once in a while on my EX30 and it has been the bottom blade holder letting the blade slip slightly and it loosens the tension a tad bit. After tightening the blade holder and adjusting the tension back it purrs. Steve

          Hi, I have an ex 21 and am having an awful time with my blade bouncing around. I have tried adjusting everything I can. Any thoughts?

            CW,
            If I were you I'd contact Ray at seyco.com and ask his advice.

            Check your pm's.

              Doug and Mike,

              My saw sits on its plywood transport base, atop various sponges and things to dull the vibration into the floor (I'm on the 3rd floor in a block). Believe it or not, it works just fine.
              But I can definitely hear the rattle is from somewhere at the blade end, and now something is going on inside the top arm itself.
              I have decided to train myself to ignore it because my mechanic in England always told me to stop worrying about the noises in my van, just wait until something goes wrong.

              Mike, do you mean that there is nothing that should be oiled on an Ex?
              What's a pm? (apart from an afternoon)

              Steve,
              I can tell you for sure, the blades aren't coming loose.

              CWeldSparks,
              Can you give us more exact details about what your blades do?

              Many thanks All,

              Karsten.

                Karsten, a PM is a Private message. I am unaware of oiling points on my ex21. I have sent an e-mail ray for clarification.

                  Here is Rays response.

                  NO oiling. The bearings are permanently lubricated with grease and oil would dilute and destroy the grease.

                          Many thanks Mike for your help :-)

                          So it looks like I am in the process of destrying the grease in my bearings. Maybe soon I will lose them?

                          The rattlings are increasing and spreading into the top arm. I'm starting to wonder that it might be because I use a low blade tension.

                          Anyway, I will make the time to contact Ray at Seyco.

                          This is what Walnut said according to Google Translate:

                          Ray region is Emil and you can submit this question for your saw. He's real nice person and will help everything. Sells saw Excalibur. He is very good at his work.

                          I'll be back.

                          Karsten.

                            My latest observation seems to indicate that the rattlings are because I use a lower than standard blade tension, and because of the length of the arm and the speeds involved, the top rod undergoes some kind of flexing, resulting in little knockings.

                            Karsten.

                              The rattling is is getting worse. It's intermittent. Sometimes it's downright scary. I'm still sure it's because of the lower blade tension - but this is unavoidable with the thinner blades. By yours' silence I can see I am the only scroller in the whole wide world who has this problem. This does not surprise me.
