Ok so One Way make well engineered tools and machines, no doubt about that and I aint complaining about them, and heck they a Canadian company to boot.
But man the documentation is typical of what I have become accustomed to from Engineers. They know all about it and can understand the design but they just have a hard time communicating it to others.
So wanted to buy a couple of additional jaws for my chuck, given I hope to try get some woodturning in this winter, and boy its a hard job to work out what you have and what you still can buy that would fit your chuck.
I had long ago thrown away the box that the chuck and the jaws came in so i got my chuck and a steel rule and measured my chuck jaws at min and max to determine exactly which ones i have.
You would think they would stamp a part number on the jaws somewhere.
Ok so i hook up the first one and open it and i find i have conflict with their numbers. And this has been bugging me for i don't know how long. Its had me where i cannot chuck up a block of wood because it was too big to fit into the chuck. More
So today i took a time out and called one way and got to speak to someone about this. I was so sure i was correct and that their documentation was incorrect. Nope the guy insisted.
Well i asked him to get hold of a chuck and then measure while i had him on the phone. I wanted him to explain to me what i was doing wrong.
Then while he goes off ...and i prepare my chuck by removing all the jaw pieces, I notice something and have a duh aha moment.
If you look at the first pic you see two slots on the face of the chuck. One is longer than the other.
Now if you turn over a jaw you see one particular piece of the Jaw that has this little roll pin in it and that pin is meant to ride in the groove, in this particular set of jaws case its supposed to go in the long groove. What this does is allow the scroll saw chuck to open to the point where the roll pin has slid all the way back. But its a safety to prevent one from opening the jaws too wide and potentially having an issue.
Here you can see a very poor picture attempting to show how the roll pin engages with the slot.
Of course as the guy came back to the phone it was like SNAP. He said did you .....and I said its ok I think I have it figured out now, and we chuckled and I said thanks for your help.
So I posted this just so you can save yourself the embarrassment if you have a Talon One Way Chuck.
But man its taken me all of 5 minutes to do this post and maybe another 5 to photograph the chuck jaws with a cell phone. Do you think these guys could put a few black and whites into their documentation and explain it all in plain visual language for the people like me.
Now I can go and order the jaws that I wanted. Hope this helps someone discover their talon chuck is bigger than they thought.
