Thread: Nova G3 chuck

teknatool have a great range of jaws. there will be something to suit the diameter you need they brought out mini jaw set and have just released a 2 jaw set for Pen blanks! sorry I don't have product codes

If 10-20 mm diameter is your aim there are a few things you might want to consider

In terms of teknatool jaws themselves

But note that 10mm really is the minimum that these jaws can grip in contracting mode for round stock to maximum 31 mm

The mini spigot jaws is the other option from teknatool - in this case for round stock the range is 8 - 30 mm diameter

Also look at the Zero jaws from sorby which will fit the tecknatool chuck

minimum size looks like 3mm diamater but i dont think i have seen the maximum diameter specified



Other options for round stock

CWS Store - Vicmarc Collet Chuck Set | Carroll's Woodcraft Supplies
Which includes a range of collets to suit a range of diameters using ER32 collets 5- 20mm

Then there is also the following pen mandrel which can act as a chuck for ER20 collets ) but only includes one collet for gripping the pen mandrel and i think the maximum diameter it can handle is 13 mm cause thats the biggest collet you can get.

Thanks guys
You have confirmed that I was looking in the right place
So I'll just buy a Nova mini spigot jaws
Teknatool® Nova Mini Spigot : CARBA-TEC
While it is $2 more at Carbatec than CWS I dont need to pay the freight charge
The Robert Sorby Patriot Zero Jaws looks good but is almost as costly as the chuck I have purchased!
Cheers

another 2 alternatives are a drill chuck for 13mm and smaller or turn a Morse taper to suit your lathe headstock both require extra Timber for the job but can be handy!
