Cole Jaws

I don't know how the Nova's are built. My OneWay's don't have a way to have both mounted at once. But yes, take them off when you're not using them. Even if you only turn under 600rpm. Those Cole Jaws get in the way! Sort of like a rotating headstock. It's awfully hard to get at the bottom of a bowl.

Yes, it's a pain to have to undo 8 screws each time I unmount a jaw set and 8 more to mount the new ones. Then another 8 to re-adjust the rubber "grabbers" (maybe twice if I guess wrong.) It makes me want to find another chuck body just for the colejaws

normally you take off the other jaws and mount the cole jaws.

Trying to remember mine came with longer screws that permitted me to mount the regular jaws on top of the cole jaws.

any good hardware store should be able to provide them or you could call Tim at the service center

Woodborg I don't have nova chucks, I do have Oneway chucks.

But don't the jaws have fitting ridges on the back of them, they would not sit just on the screws, that would make for a very sloppy fit, so no you do not place one set of jaws onto another, even if you have screws that are long enough to do so.

As for the max RPM, lawyer safety IMO, I regularly spin them at 1000 RPM, would not expect a problem with that speed, just my opinion.

I suppose it's time to admit that I own and use NOVA chucks and the Cole jaws. I have used them with the standard jaws mounted on the face. Yes, they come with longer mounting bolts to do the job right.

Since I don't cut from behind the headstock, they're not in the way on the back of a bowl, but they don't help a lot at the rim, that's for sure. As to the speed, it's more than likely a liability figure than a mechanical limitation. I run mine at almost seven hundred, and other than the ominous whoosh of air, they do hold fine.

Like the man says, limited utility. You'd almost have to plan steps in advance to gain any time even in a production mode. I did a set of salad bowls, individual size, on them, because that was one of the uses mentioned. Don't think I saved much time, and the worry for my knuckles kept them white. Takes as much time to put the buttons on as it takes to fit another set of jaws.

BTW, get a nice Yankee-type screwdriver for the buttons. You'll be glad you did.

Now I own more than one body, so the point is moot.

The cole jaws have the ridges and gooves for mounting the standard jaw

onto the cole jaws, they even come with the longer screws for this. With the size or width of these cole jaws spinning at speed for othe types of work (spindle) is just wondering what other supernova user ar doing? Mar

I tend to just wait unitl I have six or 12 bowls or so that need bottoms done and do them all at once. Just the one jaw change to deal with although it really does not take much time anyway.

Thanks guys for all your reply's. I'm just flicking through a magazin

to buy a flexible lamp with a magnetic base for the lathe (xmas presen from in-laws) and just reminded myself the cost of how much a secon chuck would cost. Imagine saying to SWMBO that i would like a second chuck because i takes ten minutes to put on the cole jaws and saying "Maybe you coul just not go clothes shopping for a little while, you know i'm wort it.............."

Thanks Woodborg, learned something again, but like I said I don't have the novas, and yes if they have indeed got the ridge and grooves than yes you could use them that way, and no unless there was some specific need to use the jaws on top of jumbo jaws, I don't think I ever would use them that way.

Consider the problems associated with hot filaments and lathe vibration. Might want to consider a gooseneck or clip flood isolated from that vibration.

I use a ceiling floodlight fixture (so it can be aimed) with a high intensity spot bulb. It is to the right and behind the lathe, aimed where I need it and controlled by a switch near the lathe. I also have a similar setup at the bandsaw, drill press and cut off saw.

I am new to this group and I ask your indlugence. I would not reccomend using standard jaws in conjunction with the cole jaws. I believe you would stress the screws, not to mention making it very difficult to turn much of anything at a speed you need. The cole jaws need to go slow. The torque is tremendous on them. To add another set of jaws and a blank, coupled with increrased speed would be beyond any reasonable safety measure. A better solution, in my opinion, is to purchase a Nova midi church (uses tommy bars) and dedicate it to the cole jaws. These chucks are available for around one hundred dollars.

Not that chuck, that chuck is not recomended for use with the cole jaws.

Hi Alexis, Thanks for your post and welcome to rcw. Please join in and "indulge" us with many posts to come.

Thank you. At work today, I checked with the Teknatool information and found that all chucks accept and work with all the jaws. There are no restrictions according to the manufacturer. They do say that the cole jaws can be used with other jaws, but in my experience, that is rather chancy at best. Here, I have my original version of the Nova chuck (the same as the present midi chuck) permanently set up with cole jaws. Also, the new G3 chuck is a good choice, though a little more expensive.

I start off with my blank mounted on a faceplate and turn the outside and bottom first, getting them near to the shape I want. I turn a recessed dovetail in the bottom and mount that onto the chuck. Then I remove the faceplate and turn the inside. I sand the inside and much of the outside as I can safely reach and apply EEE Ultrashine followed by Shellawax cream. Then I mount the bowl in the Cole Jaws and finish turning the bottom using a light touch. Then I apply the finishes. So, as you can see I never have to turn close to the Cole jaws.

As far as having the Cole jaws mounted on the chuck but not holding a bowl, I can't see a speed limit on them. If there's nothing held in them there's nothing to come flying off. Of course there's always the problem of getting your hand in the way. I've had my fingers bumped by the rubber grippers while sanding but it wasn't much of a bump.

Now for my question. Where can I buy replacement rubber grippers at a reasonable price? So far the cheapest I've seen is a set of 8 for $13.99. I'd expect a set of 8 to cost 5 bucks or so. Is there anything else that can be substituted, like rubber feet sold at some hardware store? So far I haven't found anything I can use as a replacement.

I needed some grippers that would grip about 1 inch from the face of my cole jaws. Black was out of the question - they tend to leave marks on light wood. So my solution was to use some stoppers from a local HomeBrew shop

Homebrew shops have stoppers in a variety of diameters for fermenting wine and beer. And all I've seen in these shops are a white rubber. They come solid, one and two holes. The holes are a bit oversize for the typical Cole Jaw screws, and they holes may not be all drilled on the center, but a little time centering the work will fix that.
