spindle extender?

Hi Don

What's stopping you from drilling it yourself ??

Have fun and take care Leo Van Der Loo

I put that idea in my hat band for another trip to town and someone with the ablity to drill thru 3 inches of metal..

^^^^^^^^^^^^^^^^^^^ If you have a drill bit that's over three inches long, you have that ability yourself. Use a Jacobs chuck in your tailstock.

BTW, the question about weakening the spindle extender (I guess that's the same as a spindle adapter) was thoroughly explored here a couple of years ago. Do not worry--the metal close to the center line contributes almost nothing to the stiffness.

IMPLANTS DON'T WORK???????

Hi Don, To keep my thinking about your spindle extender 'inside the box' would you elaborate. How do you plan to use it? What are your spindle, vacuum line & chamber, and chuck designs & sizes? I ask because the usual extenders end unthreaded with a female MT and have an open drift slot. I may be way off base, but I think most vacuum systems use a threaded spindle for attaching chucks, so I wonder if you should consider an adapter to couple the spindle to a hollow pipe thrreaded at the end for extending.

Let the laughter begin. I may not help you, but I might learn something from your query. :)

Arch: I have a vicmarc 300 lathe and many of the natural edged bowls i turn are too deep to allow my oneway vacum acsessories i use on the headstock . with a spindle extender threaded onto the headstock i would gain another three inches of head room. I could make new ones from mdf etc but there would just be some more tools to shuffle around with. the vacum system is a 3/4hp gast vac system with one of those threaded rods thru the headstock . I guess i will buy a regular extension and have it drilled out. As it is now i use a reverse jam with a hardwood extension in my four jaw chuck. with several different dias. hope this is what u r asking about. Don

(clip) ^^^^^^^^^^^^^^^ Don, I think you are making this more difficult than it has to be. You can make the vacuum chuck as thick as you need to to make the edges of the bowl clear. Most of my vacuum chucking is done with chunks of waste wood that are turned to suit the particular job. When a job is done, I keep the piece of wood against the next time I can use it. Usually, in the pile I have accumulated I can find something that can be used again with minor modification.
