Dead center wobble in headstock

[MiteyF]

I've been turning more and more with a dead center in my headstock, for pens when TBC, and other projects.

My MT1 dead center has a definite wobble. I don't have this problem when using chucks, mandrels etc. I've been able to work around it, but I'd like to nip the problem in the bud. Is there a good way to clean/refurbish the MT1 taper in my headstock? Something like very fine sandpaper and something with a #1 taper, spun lightly?

Thanks in advance.

The first thing that came to mind for me: on some head stocks they don't take morse tapers beyond a certain length. If your dead center is 1/32" too long, it may not be seating deep enough. That happened to me once about 10 years ago. I had to grind the tail end of the morse taper for it to go all the way in and seat correctly.

It probably is not your problem but do check it out.

You have mandrels that are MT1 and do NOT have the wobble?


Then it is your dead center--buy a new one, they are not expensive!! You will never make a great pen if the center is wobbling!!

If you are "cleaning" the MT1 socket in the headstock be "exceedingly" careful !!

Your first attempt at cleaning should be with a solvent and soft rag.

I would never use an abrasive or sandpaper ... not even with a properly shaped MT1 hone. . That's a job for a professional, IMHO.

The long and short of it is, it's a cheap $100-ish lathe, that I've just used to see if I really like turning. After 100ish projects, and lots of... ahem... "fixing" (shimming, cleaning, etc) it's working quite well for small projects. Certainly nothing worth letting a "professional" mess with. Besides, I don't let anyone else fix my tools, cars, motorcycles or anything else.

Hank, I'll check for a depth issue first. Thanks!

The wording of your original post suggests that this is a problem that has gotten progressively worse, and that suggests that the problem is that dust and other crud may be accumulating inside the taper. Before using sandpaper, or a taper grinding tool, I would try some of the less destructive cleaning methods.

There are purpose-made tools for cleaning tapers (the 'green wienie' sold by Craft Supplies, for example). But you can purchase a brass 20 gauge shotgun barrel cleaning brush locally for much less, and it will do a very good job.

You can also use a toothbrush. A soft one - just like your dentist recommends.

Mono, there's no way a toothbrush will fit in an MT1, although gun cleaning supplies are a wonderful idea! I've got everything from .22 up to 12 gauge, brushes, snakes, oil etc. These are the wonderful types of suggestions I come here for. Thank you!

Take a black marker like a sharpie and draw 3 or 4 lines the length of the dead center, spaced around it.
Place it in the headstock and ,before it is fully seated, rotate it back and forth as you seat it.
Then pull it out and see if it has smudged the marked lines all the way along the dead center.
That will tell you if it is seating correctly.

Do you have any other 1MT accessories to try in the headstock?

What lathe, source and model number?

Dale, I'll give the sharpie trick a try.

Dog, the only other #1 accessories I have are a pen mandrel (which I don't really trust to be straight, nor do I use it) and some live centers. It's the Wen tabletop lathe, exactly the same as the HF model with different colors and branding. Like I said, anything that I screw on to the 1"x8 threads spins true as can be. Guess I'll stick a live center in and see what they do. The dead center is the only thing I ever use on the head stock with a taper.

 

[MiteyF]

Creid, I think $25 is a bit steep for that guy, especially for a cheap lathe. When I upgrade I'll be picking up something with a #2 taper, so as many accessories as possible have been 1"x8 threads, instead of #1 taper.

" less destructive cleaning methods."
Good advice. My rountine cleaning involves twisting up some paper towels into a taper, soaking well with WD-40 and turning by hand in the headstock. Follow that with clean and dry paper towel. So far, has worked for me.

I bought one of those cleaning sticks along time ago when they were less expensive. I was actually surprised how well they work. I use mine on my 3 lathes plus when I go to the local club events I clean the clubs 10 lathes with it. Before I had it I used the paper towel method mentioned above. That worked very well I just find the stick to be quicker.

Take a 3/8" dowel, cut a saw kerf about 3" long and insert a small piece of craft foam in the kerf. Spray with WD40 or acetone and you have a cheap MT cleaner.
