Sphere Jig Accessory Question

Sphere Jig Accessory Question

david delo

In Brian Mills sphere jig video, he shows a couple arbor extensions. Headstock side looks to be MT2 and can't tell if tailstock side is MT2 or connected in some type of revolving center. Can't see if the business end of these arbors are flat, 2-prong, 4-prong or step center type. Anyone ever see these before and know a vendor that carries these? Might be home brew but they look as if they could be an pretty good at saving material length so you can swing your jig left and right and avoid hitting headstock or tailstock. Shows this at the 1:47 mark of the video.

The arbors appear to be a ring or cup with a central point.

Perhaps home made. If you do not have a metal lathe you can purchase components to achieve the same functionality.

Using single site for reference. Cannot add more than one link to a thread so posting the links as text.

Easy to find as Live Center. One example.

For the headstock easier to find a spur drive. One example.

To get more "elbow" room at either end, use an MT2 extension, sometimes called a sleeve. This is MT2 - MT2

Thanks David,

I'm aware of the extensions you linked and use one on my headstock side. I'll probably get another for tailstock side but am trying to see if "maybe" those shown in the Mills video might be a store bought option. The MT2 extensions get you out close to 3.5" but I was looking to get out closer to 6". I think Craft Supplies use to carry something like that but they don't seem to be available in that length any longer or anywhere else that I've been able to find.

I'm guessing that if he can make the sphere jig he can also make whatever MT2 drive or extension he wants for either end of the lathe. Those looks like they might be one-offs made by him. Awesome jig though.

I emailed Brian and he said he makes the item in question so they were a home brew solution. He going to get me a price to make them.
