I bought a OneWay Tallon chuck at a garage sale from a turner who was retiring to a retirement residence and giving up woodturning. I paid very little for this chuck. No jaws were with the chuck and slides were not installed.
What jaws are best for this chuck? I have Axminster 4” dovetail jaws and their C jaws. I’m thinking the #2 profile jaws would be the best choice, but I know very little about the OneWay chucks and jaws. Also what are the screw dimension that hold the jaws? They are not expensive until you add the shipping. Can they be bought at a local hardware store?

Now the strange. He likely hated this chuck as it may have been hard to open/close. When I installed the jaws putting the number #1 jaw in the chuck where the body was marked #1 the #2 jaw it would lock up and prevented me from installing the #3 jaw. I had to put the #1 jaw where I tried to put the #2 jaw to get all of the jaws installed and work correctly. I think either the body or jaws are marked incorrectly. I really don’t know. I have two choices, either remove the pin and put the jaws on same number as the slide, or put the jaw with the pin on the slide that has the groove.


You can see where I believe the pin was dragging on the chuck when the jaws were installed matching the slide. I believe the slides can only be installed one way to match the scroll gear and the #4 slide needs to be installed next to the #1 marked on the body.

I know very little about OneWay chucks, so other possibilities are welcome.

I have the one way std -tommy bars- but I don't think the jaws themselves are numbered. The one with the pin can be placed on either 1 or 3 per your numbers and not on 2 or 4. The #3 allows the jaws to open wider, while the #1 keeps a smaller diameter. The pin is a safety to prevent the jaws from being opened and having them fall out --it acts as a stop.
The body mark #1 is to hold the gear slide # 1. Any jaw can be put on it. When you insert slide marked 1 (it may be hard to see but they should be stamped on the end of each slide) you then turn (in the direction to close the jaws) until the next slot will catch slide 2. Keep closing and install slide 3 and 4. The process is much easier to do than may directions.:)
Simple the jaw with pin is either attached to 1 or 3 slide. Slide #1 must be inserted at body #1 and catch the spiral. Start to close the jay and catch the spiral for jaw 2. Continue for 3 and 4 slide.
One way sent extra screws at no cost when I had ordered something. I have the three sets of jaws 1,2,3 and the flat jaws the I have installed LARGE wooden jaws that will hold up to 14".
 
Looking at your picture, if you have the slides numbered base on the stamp on the end they are in the wrong positions. Slide 1 should be at body mark 1 and 2,3 and 4 should follow in clockwise directions per previous post. Sorry I missed that.

Right, I was gonna point out that the one he has marked in red as #3 (between 1 and 4 in sharpie on the body) if you look right next to it there's that groove in the chuck body to accept the stop limiter pin in the #4 chuck jaw (so you don't back out the slides so far that they fall out) So if he has the (in red) marks corresponding to numbering on the jaw slides, I think they might be in the wrong place (Or, the prior owner put in a different set of jaw slides that weren't matched up with the chuck?)
 
Bob, Brian thanks for the input. I agree with the “should be”, but it doesn’t work putting slide #1 where the body is marked #1. When I put slide #1 and put slide #2 in the scroll will not advance to allow me to put in slide #3, it locks up. I’ve tried several times. I think the slides were mis-marked from oneway. To me it appears the original owner put the jaws on the numbered slide, showing there drag marks on the chuck from the pin. I am fairly certain you can only get the slides to work when installed in one position. As you can see the slides come completely together when fully closed. What I mean is you can’t start slide #1 at any location, it can only be started in one location for the slides to fully closed. Right now I believe OneWay mis-marked the body position (most likely) or the slides.


Edit: the chuck body is marked correctly. I’ll try again to see if I can get these jaws to work starting #1 withe the chuck body marked #1,

Oneway does make mistakes. I have a Stronghold, and purchased a set of #2 tower jaws that ended up being mis-machined. Been a while, but I think the base thickness of 1 or 2 jaws was incorrect - OW sent a new set that were ok.

It appears that you are right about the slides being marked wrong. The fact that the slides "come together" at the center indicates the position you have them in is correct. Oneway jaws are not required to go in s specific position, except for the jaw with the pin, which can go in either of the slotted positions.. If you have not done so, Take the chuck completely apart and degrease and clean. Inspect wear marks etc. to look for any odd interference, and deburr sharp edges. Every chuck I have has benefitted from this. I coat all friction surfaces with paste wax and put back together. Blowing the chuck out with air occasionally keeps it working great.

As for which jaws, there's personal preference and size of work/tenons. I use tenons 98% of the time. Oneway is the only mfr that uses their patented profile design, and I much prefer it. The design allows a superior grip at larger jaw openings than perfect circle. I prefer the profiled tower jaws - the Talon jaws will be similar to the SH jaws - these allow a 1-1/4" long spigot for tall pieces, and have a ~1/4" deep dovetail at the top. For bowls and shorter forms, I just use the dovetail. I prefer how the jaws provide ~1" extra clearance from the base to work on the lower part of the piece. I have #2 & #3 profile tower jaws, & #5 aluminum profiled jaws. I never use the std jaws that came with the chuck. There are smaller jaws available, but I have other chucks I use for that. There are regular height and "round" dovetail jaws available if that is your preference.
 
The other possibility would be if the slots in the body were rotated 90 degrees clockwise and the #1 mark was rotated 90 degrees counter clockwise every thing would be correct. I don’t believe it matters what jaw slide the jaw is installed on, only that the pin matches the groove. Likely jaws are now CNC machined individually instead of machined as a circle and cut, so they are all the same except for the pin.

I did try and start the #1 slide in each location and the jaws will only fully close in the position I have it now.

One option is to start with the #2 base jaw, next #3 base jaw, then #4 and finish up with #1 base jaw. When all else fails, give Oneway a call. I’m positive they will be more than happy to help.
 
Here is link to how to install. https://oneway.ca/manuals
That was the first time in 20 years that I new of a manual for the chuck. :confused:
Took one of my chucks apart and found out that you only need to remove the jaw with pin to undo/remove slides per manual.
Also I notice that the slides have the first tooth at different distances from the center which will indicate the order if not marked.
I did not remove all the jaws, but put three of the slides back incorrectly and the jaws would not close.
 
The scratch marks must be from the pin that extends from one of the chuck jaws to either prevent the jaws from being opened so wide that they fall off (long slot) or prevent the jaws from even opening to where they present a hazard for beginners (short slot). It looks like he forced the chuck jaw with the pin into non-slot positions. The chuck jaws can be installed in any positions provided the pin fits into a slot. You will want to use the long slot. The base jaws can only be installed one way. Here's the base jaw installation video from Oneway

Jaw choice depends on what you turn. The #2 jaws are the most versatile. Profiled hold well but will bruise the wood. #3 are useful for platters and bigger bowls. Jumbo jaws are jumbo jaws. Step jaws can be useful for small things but would not be my first choice. I use only talon chucks and have no complaints.
 
@bob elliott I sent OneWay an email describing this. My conclusion. is I just need to ignore the base slide number and put the jaw with the pin next to the groove.

@BobCoates Thanks for the screw info. I actually have some and don’t need to buy any.

@Doug Freeman You make it tough deciding between the #2 profile jaws and the tower jaws. Leaning toward the tower jaws.

@Holmes Anderson I agree and that is the way I installed them, but I had to put the number 1 slide nest to the slot to get it to work. I have Axminster chuck and do this anytime I change saws as I have the slides permanently installed on the jaws so I don’t have to remove screws.

@William Rogers have you checked what Bob recommended? This will tell you if a slide is #’d wrong. After doing this check, flip the slides over (to the top of them), line them up again, and see if the screw holes and other features line up on all 4 slides - they are supposed to be identical.

Oneway jaws do not have to be installed in a specific order. The retainer pin can be moved to any other jaw (it doesn’t really help you).
 
ok, here we go OPERATOR ERROR

I finally got the base slides in the correct locations to work. What I believe was happening was the #1 slide at the initial install was hanging down and the next tooth was getting caught simulating it locking up. I backed off and held the slide up to get it to advance for each slide. Everyone was right and I was wrong. Thank you all so much for the input. I really couldn’t get it figured out and having 4 Axminister chuck doing this all the time I didnt understand what was going on. Thanks again.
