  • Excalibur EX-21 Issue with blade holder

    Hello everyone

    I was wondering if anyone had an issue with the blade holder on the Excalibur EX-21. There is an allen screw (#37 in the attached part disgram) opposite to the butterfly used to tighten the blade that keeps getting loose. The result is that this screw eventually turns inside the holder resulting in a bending of the blade and a misalignment when you tighten the butterfly. The fix is quite easy as you simply need to tighten that screw against the butterfly again.

    But it does not make sense that you cannnot lock this screw in a permanent position and avoid the loosening up.

    Am I missing something? Does anybody else have this problem?

        Locktite is designed to keep screws or bolts from loosening. Apply a small dab onto the threads of the jack screw. Then install back into the blade clamp. The blue locktite allows the screw to be backed out when needed. Red locktite is permanent, so don't use it.
        You can find it in the auto department of most hardware stores, Walmart and of course Auto Parts stores.

              My wife and I got the Moderna vaccine with our second shot last week. We had no reaction after the first shot but both of us had some body and fatigue for two days after the 2nd dose.

              Here in Mid-Michigan, my wife & I (both 65) got our first shot - the Pfizer one - last Sunday; with our second one scheduled for March 21st. Both of us were a little fatigued that evening... went to be early. Next day, just had a sore arm where we received the shot. Hope it's that way with the second...

              My first creation in intarsia , with a gift from my sister of that little puffin in stained glass. After couple of tests , I created this frame , as in my blue heron, and put the puffin leaving the water and waves, between rocks and with a look to his smiling rock mounster, on a beautiful sunset....
