Greetings. A few months ago I bought a used HF 33686 mill/drill and have been learning how to use it. Still some way to go there. As I was working on installing a TouchDRO system I was up close and personal with the machine and noticed that when I grab the spindle by hand and turn it it moves a degree or two and then stops. I can turn it back and forth and I hear audible clanks as it hits one spline and then back to the other. Here is a short video showing the movement and sound:
I don't know if this is normal or not. I figure there needs to be some clearance so the spline can go up and down through the pulley on top. I also figured that once it starts rotating it will just bear on one spline so this movement when stopped is no big deal.
Of course, I am often very, very wrong in these matters so I figured some of you that have more experience may be able to clue me in.
Thanks in advance.
Tom
