Drill Press shaft will not stay in palce

[Michael Thuman]

I have a morse and taper shaft on my drill press that is constantly falling out.

Especially when I need it to cut mortise.

Is it misalignment in my mortise attachments that are causing the M&T to slip out?

I do not not think so.

But then why won't it stay in.

I will google it but you gents are my favorites with multiple options.

You probably already have done this but be sure it is clean and free of any oil

Check for scars on it and in the taper.  Drill bits get stuck and spin in the chuck and become scarred and leave a burr.   The same can happen when the taper comes loose.  Check for and remove any that may be there.  Try not to sand the whole shaft or taper just the scarred parts. 

 

As a last resort put a long bolt in the chuck until it bottoms out and give it a few taps with the hammer.

 

The mortise chisel may be sticking in the wood and pulling it out.  Drill presses are not the best choice for that job.

Yes you can.  Maybe even tap ends with hammer.  Be careful we don't need any red leaks.

All resolve cleaned the drill press chuck with some lacquer thinner and clean the taper until the qtips came out clean.

Pressed it in place and then taped lightly with my dead blow hammer.  Then it is working just as good as before.

Looks like some bearing up high was leaking need to check that out when I hear the noise change or when I can get to it.

But it is working great now thanks all.
