Thread: Chuck identification

Wow I have one of them also. But looking at your's mine is missing the centrebit.
I think these are pre scroll chucks.

That is a Teknatool chuck, I forget the name it was sold under. It was designed for turning bowls from green timber and had bronze instead of steel jaws. Steel reacts with tanin in wood and produces deep black stains. The four bronze jaws pivoted and each "jaw" had two contact points. The jaws pivoted to compensate for the bowl not being round after the timber dried. The chuck operates in both compression (for spiggots) or expansion to fit into a recess in the hole in the bottom of the bowl. It was supplied with two "C" spanners for tightening the chrome ring on the front of the chuck and also the locking nut at the back on the insert. It was a very good chuck but you needed an extra pair of hands to fit the dried bowl and use the spanners. It was also supplied with a screw chuck. I have one and used it a lot. That chuck has been superceded by the now popular scroll chuck. Must have a look and see if I can find it, it is somewhere in the shed.

Thank you so much Jim for the detailed reply. I shall now be able to educate all the other club members, all of whom had never seen anything like this before.

Found the chuck in the shed this afternoon. It was in fact supplied with two sets of jaws. One as described before with a second set of jaws similar to those used in the current chucks, but made from bronze. The two types can be seen in the photo at the beginning of the thread. The insert had a hole in it to accomodate a double ended screw chuck, one end has a left hand thread. There is a securing grub screw at the large end of the taper on the insert.

Thanks again for your knowledge and willingness to help a newbie.
Green wood turning seems to be something I might have to consider.

Cheers

Hi all,
Looking at this chuck I thought I got something like that, I purchased a lot of turning tools a while ago and was given a box of jaws no chuck I have 7 sets of jaws for this chuck if they are of any use to anyone let me know they range in size from 24mm - 100mm there was a piece of paper work with them that called it a multi-chuck II and lists a range of jaws in the range I mentioned.
Regards Rod.
