Nova Scroll chuck by Tekna tool international

[phillywood]

I like to know any one's opinion who knows or owns this chuck. a local member had it and he said that he is not going to use it any more and I'd like to know if this chuck is a good chuck to own and would be helpful in penturning as well as bowl or spindle turning. He has made a special box for it's accessories and looks clean. Also, if you could help me to give him a fair price on purchasing this chuck form him.
Any comments are greatly appreciated.

Phil,
Nova chucks are very good chucks.
If it is the two bar style, they are typically on sale at woodcraft a few times a year for around 75-80 dollars, so around 50-60 is a fair price.
If it is a supernova or supernova2 or g3, then around 100 would be a fair price.

Phil -- to add to Jerry's comments --- Nova chucks have a lot of different jaws available. One, about 2 inches capacity is normally included with the chuck. There are larger ones and smaller ones.

The one known as a "pin" jaws -- the 4 jaws together stick out like a snout and when closed are about 1 inches (25mm) in diameter -- are handy for pen turning.

Extra jaws are worth used about 20=25 each if you can see a use for them.

There are some that have very limited uses and value.

Jerry, this one form what I look at has four jaws that are numbered and they open up to 50 mm I guess. I will measure them tomorrow to see what they exactly are. I was wondering if you can use this on the headstock to hold the blank and I need to buy a chuck for the tail stock for drilling, am I correct?

Phillip:
One thing to check is to make certain you know your headstock size. The Nova midi chuck works with 1x8 tpi. It can not be adapted. Most of the other Nova chucks will take a threaded adapter. The Nova must be 1 x 8 (which is a standard size for jet mini and turncrafter pro and several others).

If you have a lathe brand other than those the midi may not work at all.

Nova's midi does not use threaded inserts like their other models, but you can buy adapters to go to other size spindles. I have three lathes one is 3/4 16 and I have an adapter that works like a charm.

Phil,

I have a Nova G3, the model with the chuck key, and like it a lot. I am also considering buying the Midi that uses the tommy bars, since Woodcraft has it on sale with the mini jaw set (4 sets of jaws). An extra chuck is nice to have, especially if you change jaws often. I would recommend going to the Teknatool website to learn more bout wht these chucks can do. One thing I didn't think of is that the 4 jaws can grip round stock, but the jaws can also be used on square stock, and the spaces between the 4 jaws are used to clamp onto the edges of the square stock. Lots of options for chucking in compression and expansion mode.

If you have not bought a drill chuck yet, I'd recommend getting one that has a threaded Morse taper (usually 1/4-20). This will keep the drill chuck from accidentally coming out of the headstock if using for holding a dowel or mandrel. All you need is a piece of allthread to screw into the end of the chuck's Morse taper, and secure it out the headstock hole with a nut or knob. I use a threaded knob from Rockler, but you can threaded knobs at any wordworkign store. Or you can just use a washer and nut.

And if you are really into turning, make a wooden knob, and epoxy in a 1/4-20 threaded insert.

I have this chuck and it works great. I bought it the last time that Woodcraft had a sale with all of the jaws included. I use it for all kinds of turnings-bowls, screwdrivers, stoppers, seam rippers, whisks, etc. I have several chucks set up with different size jaws, this makes it easier to switch from one to another.
