Anyone know where a L shaped chuck key for a Stronghold chuck can be purchased?
Better get it from ONEWAY if you need a new key. They may know of L shaped keys

CAUTION
STRONG HOLD KEY is oneway’s one failure in precision. We have 3 strong hold chucks and the three keys are not interchangeable. One key won’t even pass through the hole in another chuck.
All keys have slightly different teeth. So it is likely the scrolls are threaded slightly differently as well.

I’m not aware of L shaped keys but would likely have the same issue

I have a talon chuck and a stronghold chuck bought at least ten years apart, both keys fit each other.

I have two Stronghold chucks. One is about ten years older than the other. The ring gears and pinions (key) are the same. I also have five or six Talon chucks. The pinion keys can be used in any of them.

It appears that the compatibility problem with the ring and pinion gear teeth was fixed before I started turning twenty years ago (2004).

Panning for Montana gold, with Betsy, the mule!

My first Oneway Stronghold chuck was purchased when I got my Woodfast lathe in 1992. The chuck key for this one doesn't fit the three subsequent Stronghold chucks I purchased later on.....all after 2000, I believe. The later three all have the same chuck key.

Why do you want an L-shaped chuck key ... more leverage? If so, why don't you just slide the rod to either end? You can epoxy or tack weld in place if you think that is necessary.
So I can mount bowls with a mortise on the inside. Unless the bowl is shallow a L shaped key is needed to tighten the chuck.
I currently do this with my square key chucks using a ratchet wrench.

I do this fairly often and find that, depending on the depth of the in side recess, the key doesn’t have access. Please don’t tell anyone, but I keep a large, flat bladed screwdriver handy and use it as a lever to turn the pinion gear.. It doesn’t take a lot force to secure even a large bowl securely, and once the tenon is trued,, or outside finish cuts done, I’m generally done. I. Have thought about devising a universal joint similar to those I’ve seen on socket wrench extensions…but haven’t taken the time so far.

Steve, if I had to do this, I would get a chuck ket from Oneway and cut the gear end off, then weld the bar on top of the gear end at right angle, you will not need much room to insert and remove the head.

Of course you could do it another way, leave a stub from the chuck key (not weld the head on) sticking up above the chuck body, file the stub to a hex shape, then you can use a flat ratchet wrench to tighten or loosen the chuck (faster than the other way)

Good luck :))

That's why I chose Nova chucks. I have multiple keys, but I can get another (socket, L shape, or T handle) at any hardware or auto parts store.

Good idea Leo. Hate to cut up a chuck key but looking like that is the only way.
Or just start buying more Vicmarc chucks and jaws so I can use my ratchet wrench.

Most buy the Nova chucks because they are CHEAPER :oops:, and that is fine, I bought the Oneway chucks for the much higher quality, and I still would do that, I know what I got and would certainly not trade them for Nova chucks :)

I guess I just don't understand why you would need to do that. I've never done that. I'm sure there are other work methods that would accomplish the same without the extra steps. If you have a center mark you can always true up your tenon - or even a recess, if you grind (or buy) a tool to do that. I think several people have posted photos of a tool they made just for that purpose.

The L-shaped key is wonderful. Maybe if you knew a woodturner, they could get a carriage bolt and turn a handle for you :)

Here's some I've been using for nearly 20 years. The wood handle is far more comfortable if you've got to change stock in the chuck often. I've had to label mine with a P-touch because I've also found there's an inconsistency in fit.

Also, whatever solution you choose, your design should let you apply some downward force on the pinion to reduce its natural tendency to rise when you apply torque. Otherwise, there could be rounding-over wear on the gear teeth as the pinion toe-end journal pin jumps out of its socket.

Uh-oh, I think my dog was reading over my shoulder, but he doesn't talk much and he lost his internet privileges last week.

My cat's Internet privileges are potentially on shaky ground. I've warned him about flopping down on the keyboard when I am approving new forum members. I can't prove it's his fault, but some forum members were banned. The cat claims it's Emiliano's fault. I'm not sure who to believe.
