Nova G3 Chuck Question

[Silverado]

Does anyone have a Nova G3 chuck. \\\\iam trying to hold a 1.5 inch bottle stopper. Chuck came with 3 sets of jaws and a set of Cole jaws.
None of them will hold onto 1.5" stock. Any suggestions please.

Thanks, Tim

I haven't confirmed these with actual use, but from the chart I have inside my Nova G3 chuck storage box,

So, it looks like the 35mm Spigot Jaw would be able to fit 1.5" round stock as well as 1.5" square stock.

I'm assuming you are looking for jaws suitable to hold a 1.5" inch blank so that you can drill it on the lathe?

For bottle stoppers, I use my drill press and I either drill the blank with a 5/16" drill (tap drill) and tap the blank with a 3/8-16 tap, or I drill the blank with either a 17/16" or 29/64" drill and glue in a 3/8-16 threaded insert.

For turning I use one of several methods I have. One is a dedicated Bottle Stopper MT2 mandrel and the other is a set of mandrels that are held in either a collet chuck or in a jacobs chuck on the headstock, like these:

I suppose to drill on your lathe, in a pinch, you might be able to mount your blank between centers and turn a tenon down on one end then use the tenon in one of the Nova jaws you do have in order to drill it on the lathe - that is if you have a set of jaws that will hold round stock in the range of the tenon you make.

I hope this helps - Dave

Thank-you Dave for the Fast Reply. Yes I do drill on my Lathe so I need to hold 1.5" cylindrical stopper Blanks. I do have some that look Similar to the 35MM Spigot Jaws. I will look into getting a set of these . What I did to get me by today was cut a 1.5 inch piece of PVC pipe off then cut it into 2 halves, then stretched it to fit around stopper blank and then pinch it in my chuck jaws.

Thanks Again for the help on this.

Take Care!
Tim
