  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

So, I've made a number of jump-rings for my girlfriend to use on one of her projects. They are 1/8" inch stainless steel, with a little over 1.5" diameter.

She needs to slightly open the rings a little bit in order to snap them into places. The problem is there doesn't seem to be jewelry stores that sell tools for something this big. I have been looking around and the closest thing I can find that maybe can fit the job are reversible Snap Ring Pliers.

There are a few issues with them though.

  • Most can't be used for rings that need to expand up to 1.5" or more.
  • A lot of the tips won't hold up against strong pressure
  • Making sure her hands don't get sore trying to get leverage
I am curious if we are on the right track here though, or if there is some other tool under a different name that would fit the project much better.

If worse comes to worse, I can try to just invent my own method and perhaps use some round-bar with a pin in my Mill to make our own plier-type tool. But that would take some time and experimentation...

Hi,
The snap rings I am familiar with aren't spread open like external c-clips but rather grasped with two pliers one on either side of the gap and twisted sideways to provide an opening.

Are these some how different?

There is a tool called a link spreader, I believe, that electricians use for chandelier chains. I've had it used twice when we were taking down very heavy chrystal chandeliers. Not all electricians have them, most favour the "twist from opposite sides" method mentioned above, as do I. But it is out there.

Don't think a link spreader will work but the ones in post 2 should work unless the op is talking about a chain

The Princess auto looks to be a quality tool.

Don't count on it. Some of the Chinese made ones look really nice until the handles bend, the snap ring warps, and the plier tips break off the first time you use them. Snap ring pliers are a good place to splurge a bit for quality tools.

Pictures can lie. Hands on inspection, most likely not.

if you can find a spreader jaw for an old Eifel geared plierench it would work very good and it is adjustable ----it is geared so your wife could easily squeeze it----another tool that could maybe be modified to work good is a piston ring spreader tool---Dave

1.5" inner diameter. I'd like to expand even larger.

I found something at Home Depot (Atron Chain Pliers) but no hard stats given. I may ask them to take a look at it and see if it's something I could use.

Or, I'll simply drop by Princess Auto and do a modification to this tool:

I am still trying to understand your application. Normally I twist jump rings sideways with two pliers to open and then twist back to close. Often depending on material if I spread them and then try to close, due to the spring back they won't close tightly. Are you going to have to close them tightly after you are done?

You mentioned these. I've used these LOTS as an electrician installing the custom lights in a house. I have two paires. They are not difficult to use. Little tricky to get oriented at first if you've never used them before, but it gets easier. I'm a big guy with strong manly hands, but I wouldn't imagine getting sore or tired would be much of an issue unless she's doing hundreds of rings, in which case, not really anything short of automation is going to solve that.

Kukshawn, I grabbed a pair at Home Depot yesterday and she gave them a try. It was just a tad undersized, but using a special TRICK she got it to work fine so it looks like we are all good for now (finally).

I realized after I posted you were looking for something capable of 1.5” and those spreaders would be tight.
I’m glad you got it worked out.

....one thing NOT mentioned above: Safety.

I don't know about "jump rings" in particular, but I know many other types of snap rings can fire off in random directions with surprising speed and energy. All it takes is for the snap ring to slip off the pliers and zzzzing!

So get her a pair of safety glasses too!

No kidding. I used a snap-ring to get a small c-clamp off part of my mini-mill a couple weeks ago. The damn thing shot off like a bullet ricocheting all over the basement. I was of course, wearing my eye-glasses. I always wear them any time I am working with anything under any kind of force/stress. I've learned lessons from observing my own father's eye injuries in the shop.
