    The photos in the PDF appear to have a different shaft lock button. On top of that, the rotary tool doesn’t allow the cutter bit to sit as deep as shown in the PDF. I have at least 1/2 inch of cutter exposed, which doesn’t allow the lock button to sit below the mount.

    I’m using the single flute 1/16″ end mill supplied with the rotary tool. I have remove the plastic collar to get it to sit a bit deeper in the rotary tool. (ref: https://knkusa.com/product/rotary-bit-116-singel-fl-endmill/ )

    The shaft definitely doesn’t spin with teh button held down.

    Thankfully I have a 3D printer sitting next to the Force and I’m going to try to re-engineer the rotary tool holder to allow more room for that button. I’ll post a link to it here. It should be identical, except for the space between the green body of the tool and the locking screw that clamps it in place.

    No one using the rotary tool has reported this issue. Also, if you compare my photos, you’ll see that in the last one in that section, the rotary tool is mounted higher where by the lock button is NOT below the adaptor.   Thus, I had slipped the tool up higher when I actually got it mounted.  Sorry about that!

    You can also verify this by watching Darrel’s video here:  https://www.youtube.com/watch?v=bSfOWWnNWyM

    My newly printed mount solved the problem nicely. I’ll post up some pictures tomorrow.

     

    Not a huge deal for me since I make design and make things all day, but it could be an issue for someone else.

    Hello,

    I ran into this issue as well!

    There seems to be a new batch of rotary tools.

    The shape of the new lock button is like a mushroom head, which results in a permanently triggered lock button when fitted accordingly.

    Do you have any solution for this? I agree with Matt that there is a necessity to resolve this problem for future customers.

    @myates: Can you please send me a link to the model data of your re-engineered rotary tool holder?

    Thanks in advance and best regards

    Thanks for bringing this to our attention! We will make adjustments accordingly. The factory for our rotary tools obviously changed the design without alerting us, so this was completely overlooked.

     

    @myates – Would you consider sharing your design?

    @alex – Please send in a ticket and we will get you a new adapter, once we have it created.

    Sorry for the long wait before my reply. Work is crazy and I had to find the random folder where I saved the model for this thing. Pictures attached and link to Thingiverse below.

    Note that I used a #4-40 threaded insert instead of the square nut, but it should work with either (you can see the brass insert peeking out the edge). I’m not sure how long the original screw was, but I think mine’s longer.

    Hello,

    @myates: Thank you very much for your model data.

    @chadknk: May you send me a printed version? I am happy that I can use myates object data but have no access to a 3d printer currently (although can print replacements later by myself). So I would like to embrace your offer to send me a corrected version. I did not receive an answer to my ticket request yet.

    Thank you and best regards

    @geneo: No problem at all. Please email me your shipping info and I will have one sent off.
