- Another heirloom tool repair with a story. My buddy Chet's great uncle Leo owned this Snap On "Ferret" ratchet back in the 40's. He worked at the United airlines maintenance facility in San Francisco and did aircraft repairs and service . The ball detent socket retainer was damaged some time ago so lets see if we can fix it and hopefully not have a visit from Mr Bozo.

Over the top Tom!! No words to describe my gratitude for sharing your time, knowledge and expertise with us. I'm sure my great uncle Leo would be thrilled as I am
Hey Chet, Thanks for providing a fun little project. The ratchet is sitting on the table in my office.
Cheers,
Tom
"here's its modern contemporary... I bought this in 1986."
Now that you say that it is actually pretty funny.
Cheers,
Tom
Nobody and I mean nobody would attempt this kind of “repair”. I’m so impressed by your thinking process and manufacturing skills to achieve such a high level of precision using human sized fingers to complete this. Tom you’re back in a big way. Great job.
More like Italian sausage fingers. Thanks for the nice comment.
Cheers,
Tom
Tom, you and I have met before and when this video showed up I had to run to the garage and check my tools. My dad, born in 1921, was an Army aircraft mechanic near the end of WWII. In 1949 he worked for United Airlines in the maintenance facility at SFO. When he passed away, I got all of his complete set of Craftsman tools and some other odd bits. One of those was Snap On Ferret F-70N ratchet, date code 50. He lived just off the beach in Ventura, so I serviced all of the tools with Evaporust and a lot of TLC.
After leaving United, he never had his own tools at work and eventually managed multiple departments. So the ratchet still has 90% of its chrome left and is in great shape. I have used it a couple of times. Rather small and light, but perfect for working on those aluminum airplanes. Thanks for jarring my old gray cells. Great memory of my dad a day after Fathers Day.
Hey Kurt,
Your dad may have crossed paths with Chet's uncle Leo who had this ratchet and worked at United.
Cheers,
Tom
We still have kits for these and I repair at least one of these a month. They quit using brass for the reverser pin and Phillips screws to hold it together in the 50’s. Most of the ones I see are date coded E and G from WW2 because they made crazy amounts of them.
Right on! Good to know a good company still services things like this. Thanks for the comment.
Cheers,
Tom
SnapOn RKRA380 is the repair kit for that ratchet.
@@jeffkimble8857 Well crap. Could have saved pulling out some of my non existent hair.
Cheers,
Tom
@@oxtoolco😂
@@oxtoolco Yeah but store bought lacks that personal touch! lol
I would love to see how did you manage to get the wrong one out
Me too 😊
Basically I used a carbide end mill to push down on the ball and mill off the retention portion of the insert. The ball and spring then came out and I could remove the remainder of the brass insert.
Cheers,
Tom
This is exactly the question I had and thank you Tom for answering! I’ll ask in the other plied vid how the heck you loosened them up!
$1000 shop time repair for a $90 tool - sentimental value - PRICELESS!
awesome work Tom.
True!
Cheers,
Tom
And they are guaranteed for life.😆
15:07 “table cad” nice
Perfect! Love seeing the old tools kept alive!
Thanks for sharing 🇨🇦
Tom, I appreciate how you show your bozo moments. I learn as much from them as anything else!☺️
Wow Tom! Way to make a super difficult repair......look possible. In my years of mechanic'n, I've always thought about how difficult the detent ball portion would be to make, in comparison to the rest of a ratchet. After destroying a 3/4” drive breaker handle (with a cheater pipe), I made a new square socket drive, which lacks the detent ball, but otherwise has worked flawlessly.
Excellent job, & thanks for another fantastic video!
Without the ball detent the otherwise good tool is nearly worthless and frustrating at best. Thanks for the nice comment.
Cheers,
Tom
Nice to see you again Tom!
Great to see you back, Tom!
Two awesome old-school OXTool vids back to back (lunch tray and all)!
Love it!!!
From your axe video I cleaned all my axes and mauls up. I polished them then used TEAK OIL to cover the steel as well as the handles and the results far exceeded my expectations. I mention this as a thought to polish the ratchet on the buffing wheel and apply the teak oil. I was impressed how well the oil binds to the axe head even after use and have been using it on many old refurbished tools.
Sometimes it's the simple math that bites me on projects. I guess I've take it for granted because it's so simple to over look and to focus on the harder parts WAY to much. Tom, I just want to say thanks for all you do with your UA-cam videos. As a machinist for 30+yrs now, I enjoy watching different prospectives and learning from them. It's made me a better machinist and to try to encourage and help my younger co-workers to strive to be better and take true pride in their work. If people develop a passion for Machining, it truly becomes a way of life in everything they do!
Hey Joey,
Well said. We only rent the knowledge for a while. It is all of our responsibilities to pass that knowledge on to the up and coming folks.
Cheers,
Tom
Thanks so much, Tom -- these videos are a treat. Basically like sitting down with a mentor for 40 minutes and just watching how he approaches and solves problems. To me, this is at least as valuable as a carefully scripted lesson -- here, we get to gain some insight into your problem-solving in real time. (Oh, and I'm loving the tips for zeroing the tailstock, especially the use of the carriage + DRO)
Great to see content from you again
That was a tiny assembly pressing the brass, spring, and ball in. I would have fumbled so many times that "words would be said" by me. Very interesting video, thank you for sharing.
Outstanding 👍
So glad you’re back Tom. You are one of the best!
Blimey, a 'snap-on' Ferret! What am I going to witness?
Good to see you again Tom
Hey Rusty,
Thanks for stopping by.
Cheers,
Tom
Thanks for, showing/telling on, your Mr. Bozo moments! Everyone has them, but few people show them! Keeping it honest, staying humble! 👌
Completely agree!
I have a ratchet that looks exactly like that one, but it is a "Plumb" brand. My step-father acquired it in the early '60s from a co-worker who was a part-time mechanic. At the time, it was in about the same condition as the one you are repairing, except that the detent ball was still there.
Good to see you back. Excellent informative videos.
Nice job on that ratchet. When I worked at DeLorean I used to use the super small 1/4" form factor ratchet with the 3/8" guts. That was the uber ferret and was used heavily by myself. Then there were times when no ratchet could get in...used to superglue 6x1.0 nuts to the tip of my index finger to install.
Really enjoyed the repair
You know he's a machinist when he mistakes starrett for snap on
That was funny. I was thinking wow that actually rhymed "Starrett" and "Ferret". Dohhhh!
Cheers,
Tom
Am I wrong in thinking neither the bore diameter making it curved matter? Need some basic slope on the back side to center the ball but only the escape diameter is important.
You are right. A flat interior would probably work fine with a hole for the ball to project out into. It was easier to think about doing it with a spherical seat.
Cheers,
Tom
Great work and great content, more please !
It’s hard to beat an OxTools video! Makes my day when there’s a new one to watch. Thanks Tom!
Honestly I love it when things do go according to plan. That can be some of the most educational information to help develop a problem solving thought process in your viewers.
Man I really miss your content. Don't burn yourself out going too heavy, but hopefully you can get a rhythm back to your videos.
Tom, I'm glad to see that you're human like the rest of us.
Thanks Tom . I ALWAYS learn something watching your videos .
The worse problem I hate is the retention ball spring that keeps the socket from letting go. On quick release you can fix them but the style that is not quick release, the ballbearing is like hammered in. And when the spring fails there is no tension on the socket.
You buy a rebuild kit. It has the entire anvil, and everything except the body of the ratchet. It's like $15.
Tool repair videos are some of my favorite that you do. I remember back in the early days of your channel you repaired some kind of blade scraper that was apparently a family heirloom piece! Baby Wilton from scratch vise build is my #1 all time fav .
Great attitude good stuff sir
Wonderful content, Tom. You need a tailstock DRO similar to the one I made, but I am sure, much better.
Great repair Tom, but the ratchet has an "oil" port on it, not a "grease" fitting.
I have a grease gun that is designed to inject grease into ball port fittings in particular for right angle die grinder gear heads. Oil seem not appropriate for a ratchet mechanism in my opinion. Seems like it would leak out and make a mess. Change my mind.
Cheers,
Tom
@@oxtoolco Actually shaftofshame29 is correct. These old ratchets used oil not grease. Yes the oil does leak all over so you had to oil them daily. When you use grease it seems to get in the spring and the ratchet does not work as well. You said this ratchet was like a box of rocks in a comment. If you oil it, it actually does work much better than grease and they work very well today. I know it is hard to believe but if you degrease it and oil it you will see what I mean. I have many as I said and they really do work well when oiled.
Seems like getting the ball to behave right is a bit of a guess-and-check process anyway, if you aren't able to source the exact spring and schematic. So many tiny parameters to get exactly right, you could do all of that math only to find you wanted the ball to stick out a couple thou less anyway...
I'm appreciating this series of sentimental tool repair. I wish I had tools I cared that much about, but I'm only in my mid 40s so most of my life has been a race to the bottom on tool quality.
I had a clue to ball stickout from the newer ratchet. You are right the first try it was sticking out too far.
Cheers,
Tom
So next time I take a vintage Snap-On ratchet to my tool dealer and he says it can’t be fixed but he will replace it with a shiny new replacement equivalent, I’ll just decline because I know a guy along the backroads called Tom’s Tool Hospital and Reincarnation😗😝😋
Please loose my mailing address.....
Cheers,
Tom
How did you extract the retainer after pressing it in?
Basically I used a carbide end mill to push down on the ball and mill off the retention portion of the insert. The ball and spring then came out and I could remove the remainder of the brass insert.
Cheers,
Tom
Long time no see.
Curious as to how you got misfire #1 out of there.

Good repair Tom, well worthy of the tool. My Dad used a SK 1/2 ratchet, not sure of the vintage but if I had to guess early sixties and it has similar construction for the detent. You can see the different metal around the ball. I'll have to take a look at it more closely the next time I'm at the storage place.
Hey Bill. I actually like SK tools. The old timey auto shop I used to hang out in sold SK and the older stuff is really nice. Hope to see you at the bash.
Cheers,
Tom
Love it Tom. Good stuff as always.
Damn you, Tom. I have box after box of repair part assortments. Do I have a ball bearing assortment? No, not yet, but soon. Maybe springs, too, if I see one I like.
You know that machinists cannot resist a hardened steel ball. Almost all of them have a couple rolling around their toolboxes.
Cheers,
Tom
Yes as the years go by I'm sure we all wish our springs were stiffer. It definitely affects how far we penetrate with the spherical feed. ;-)
I can send my spring measuring device if you need to check current levels.....
Cheers,
Tom
You’re the man Tom. Appreciate what you do.
Great repair! An admirable tool restoration. Two questions:
1. For precise bore depth on the lathe, would it be worth putting a chuck holder on the tool post so you could use the DRO directly? I've seen others that swear by this method.
2. What's that turning tool you're using here? It looks like it's a customized holder turned 90 degrees with a reground insert.
Tom’s back!
Practical and stylish fix - you can always count on Bozo to show up on brain science jobs.
I have the same wrench. I don't remember where I got it but have had it for years. Works just fine. Just kinda take it for granted. Maybe because it's never been shiny.
Now that was a OxTool video there, great to have you back Tom, thanks for the lessons
I have a Snap-on F-70 M with a date code of 6 or 8(?) that I bought as USAF surplus around 1970. It went to surplus because the change lever was missing and it took me until 5 years ago i.e. nearly 50 years(!) to get around to putting a new fabricated lever on and only then because I finally got fed up with doing the change over with my fingernails. Its in very sound condition with no blemishes and is my go to ratchet in preference to the modern ones that are clunky by comparison.
Your video has inspired me to repair the ball lock on my 3/8" torque wrench (also ex USAF of the same vintage), thank you.
Hey Clive. Great motivational story!
Cheers,
Tom
After your statement about the floor sweeping samples, I wonder how many people paused the video to place a quick order. I hope the pausing doesn't mess with the UA-cam analytics for your channel.
Tom! Thank you! I’m staying up late now. ❤
How did you get the misfit one back out?
Basically I used a carbide end mill to push down on the ball and mill off the retention portion of the insert. The ball and spring then came out and I could remove the remainder of the brass insert.
Cheers,
Tom
Tom today was the very rare moment where I was disappointed by something in one of your videos. When you told that you had to remove and redo. I got excited with anticipation of seeing you remove the ball retention mechanism. Only to have my hopes dashed by you not showing your methods. I understand your reluctance in showing your frustration but inquiring minds want to know. I do enjoy your new series of tool repair. As always thank you. You are a wise use of my time.
Good point. I probably should have shown how I got the pressed in one out at least. The rest of it was the same as already shown. Basically I used a carbide end mill to push down on the ball and mill off the retention portion of the insert. The ball and spring then came out and I could remove the remainder of the brass insert.
Cheers,
Tom
@@oxtoolco It is encouraging to learn that the way I would have done it worked. My concern was the possibility that the ball would not push down far enough to get at the retention portion and would just spin with the cutter. If that happened my next attempt would have been super glue the ball so it would hold still enough to be milled off. If all of that failed I was contemplating making a very small hole saw. It would not have to work that great it was only cutting brass. another option would be the rotary table and a very small milling cutter. As you see I tend to over think things and to have several contingency plans. Where would your approach differed from mine?
@@Proverbhouse Sometimes it works best just to try you first idea and see what happens. If it doesn't go as planned then make a new plan. Analysis paralysis is a real thing but at some point you have to do something. I find that allowing yourself to do something is many times the best and most efficient path.
Cheers,
Tom
Mr Bozo is the worst apprentice. Thanks for sharing the challenges.
I actually would have liked to see how you got the first attempt out of there.
I didn't think those ball-retainers were that BIG. I guess it's relative.
Thanks for the video, Tom. Bloody brilliant, as always.
very nicely nice ...
peace
Hi Tom, WOW, two tool repairs in one week, that's almost a 1/2 slice of Meatloaf! Yes Mr Bozo will rear his ugly head whenever he gets a chance, I should know! But, you overcame & persevered! NICE!! See ya at da BASH!!
I loved this!
Just an FYI, I live 2+ hours north of Sacramento and I love how you break things down to the component level. I wish I could be your apprentice despite being 46 years old. I hope all goes well for you and I look forward to your future episodes.

Hey Sal, Thanks for the nice comment. NorCal rules!

That was a nice little side project. Just like you need the right tool for the job that right man operating the tool is also critical. KOKO!
Nice job Tom! Saving tools like that, is a very noble endeavor.

It would have been interesting seeing you derive the machining depth eqn.
Nice job
Maybe not. I blew the math on that one.

Can we have a video on your Fanuc EDM? Not a machine that many of us will have in our home shop. You showed us some wiring before you commissioned it, but nothing since.
Normally the only time I need to calculate 'ball stickout' is if I have a hole in my underwear.
snapon has a repair kit for that exact wrench for $11

For a while I've been wishing I could attend the Bar Z bash. I'd like to bring spicy beef jerky but I've never found a time to make it work.
Wow back again, It looks lke a good sumer. Thanks for the video keep on keeping on.
I love these videos. I hate to see good tools get tossed. Glad to see you back in your shop and behind the camera!
I found one of these ratchets when I was around 7 years old in the mid 60s gave it to my father who was a master mechanic, he retired and gave that ratchet back to me . I still use it to this day .
That's ballsy. These ratchets are absolute hammers as far as precision and ease of use. A couple ft-lbs of back drag is about right for a 3/4 drive ratchet nowadays.
@@operator8014 Agreed, Compared to my Snap on 80 tooth this one is a box of rocks.
Cheers,

Tom, doing repair work is often my most satisfying work. Knowing I'm putting my efforts in to restore the work of a previous craftsman and so on. I also think it's the way things go when you are trying to use precision on tools like this that have long ago deformed and become slightly off from true in so many dimensions.
Bob's your uncle, or as my dad says, Robert's your father's brother 🙂
Allways a big pleasure when Mr. Bozo is coming to town paying a visit :D
Well you are welcome to entertain him at your shop for a while.....
Cheers,

@@oxtoolco In fact he was hanging around at my place before he came to you. I tried to stop him but you know how eager he can be. :D
Thank Mr Bozo for the extra learning opportunities! 😂
Tom, I just realized that I too have large Italian sausage-like fingers, and I had a revelation watching you search through the springs with tweezers. I never thought of using tweezers for this and now I forever will. Can you elaborate on the make and size of the tweezers you are using?

What ever happened to Dale, he doesn't post videos anymore, life got in the way ? Say hello from his older viewer when you see him. Thanks for posting these videos Tom, much appreciated.
Another fantastic video. Great content!
Glad to see more new vids! Keep em' comin!
I have a few 1940 ratchets like that and NONE use a brass part like that. I am 99.9% sure someone modified it year ago. I even looked online and all 1939 to 1941 snap-on ratchets I could find all all were installed my displacing the metal. I have a collection of over 100 snap-on ratchets and none have brass insert like that.
Interesting! The square drive is hardened and the hole in the square was nicely machined. The story gets more interesting now. Thanks for the comment.
Cheers,
Tom
My dad also remembers roughly within a year or two the date he aquired some 30 and 40 year old tools, When i asked him what year i was born he was off by 6... I found that quite funny.
I don't think my dad has ever known my age. I asked him to find me health insurance when I was in my early 20s, and when I went to use the insurance, the pharmacy couldn't get it to work. Well, when he signed me up, he had my birthday wrong. Lol
Thanks Tom. Nice job!!!
Well Tom, it seems that Mr. Bozo had a great visit in your shop 😂😂
It's wonderfull to have you back and to enjoy your little giggels . Well done job
Lets go dude!!! Great repair.
Great repair job Tom. Good to help out a friend. Enjoy yourself at the bash. Cheers Nobby
Keep them coming Tom. Thanks
Yes!
You put too much lube in it. That's why the ratchet sound isn't very positive.
Ewwwh. You are one of those guys that likes a loud ratchet. This one is a stealth model.
Cheers,
Tom
If he used oil (which is what these 1940's ratchets used) it would have worked perfectly. The grease gets in the spring and they don't work well. If it was degreased and oiled it would have worked like a new one but without as many teeth. I have plenty of 1940's snap-on ratchets and they work super well when oiled.
