I have had some trouble with my endpin recently. It keeps sliding and falling in (slowly, no damage to the body). I assume this is because I am 6'4" and have my endpin out past where the notches end. What can I do to make it stop sliding? Is there anything I can do other than buy a new endpin?

Double Bass Endpin Issues

Alright, I've noticed it still slides when in one of the already existing notches. What should I do?
Is the point of the thumb screw end going into the notch? or possibly, is it too flat and only straddling the notch and slipping?
Sharpen the point or make the notch wider.
Oops! I just noticed.
It slips in the existing notches? Not the new ones?These are the grooves that go all around the end pin? Correct?
Is the thumb screw tightening or is it perhaps stripped?
Correct. And the thumb screw is tightened as far as allowed, and it at no point loosens. Is the problem perhaps a lack of friction?
If you can remove the pin, look into the hole and see if the screw is long enough to tightly engage the pin.
"Lack of friction" has to be lack of (good) contact.
With the thumbsrew loosened, does the endpin seem to "click" into position at regular intervals as you
slide it through the bushing? And if so, is this how you are setting the position? If that's the case, that
could be the problem with the existing notches.
These "detent" positions, if present, will not necessarily have the notches lined up with the thumbscrew.
You have to let the screw tip "find" the notch independantly of those "detent" positions.
Turn the thumbsrew in until it just contacts the endpin. Then while maintaining just light tightening force
on the screw, slide the pin until you feel the screw tip fall into a notch. When a notch lines up with the
screw tip, it should suddenly become possible to turn the thumbscrew in further.

I am suffering the same problem
It is soooo annoying to feel your bass slippering down while playing
And no matter how tight you screw the endpin. In my case, it is because the flatness of my thick ebony endpin (engel), which has no holes or strips. I guess the only way will be drilling or stripping some spots, but the fact is that I don`t know how to do it
.
Jake from the Bass Spa, here on TB, suggested I use a 9/32 rat-tail file to make a groove all the way around my metal end pin. It worked like a charm. The same thing might work on ebony but I'm not sure.
Cutting a groove with a file should do the trick. If you have a drill press chuck your endpin into the drill press and let it extend through the hole in the platform so that the spot where you want your groove to be is just above the platform. Turn on the drill press and bring your file in against your endpin. It shouldn't take too deep of a groove, maybe a 16th inch or so. Just make sure your groove is a bit wider than your set screw.
