Hooks and Crooks 2

In this weeknight short we load test some alternate designs of the cold formed hooks suggested to us by a viewer. We use the load test dynamometer and the shop built rod bender to do the work.

[@ScoutCrafter]

Just a side note -On Snack Break 14 Tom Tested forged hooks against cold bending 3/8 rod... Interesting results! The standard S hook cold bent tested to about 850lbs before opening... Great stuff!

[@ianandrews6030]

Thank you Tom, I learn so much from being a fly on your wall. I will never call anything flat again. Shearing knowledge is priceless.

[@DoctorBloo]

The pop that those pins make when they're removed is incredibly satisfying.

[@ckvasnic1]

Product development is just that. Development. Those are nice developments of the original. Thanks for sharing your time and talent. All the best. Chuck.

[@oxtoolco]

Hey Chuck, Test, characterize, improve, economize. Something like that. Thanks for the comment. Cheers, Tom

[@ScoutCrafter]

Hey Tom that was Awesome! 1000+ pounds with 3/8 rod!!! I agree they don't have the cool look of an S hook... The bushings and bushing receiver hole has a fit that screams precision... Well done!!!! Thanks for sharing... ;)

[@oxtoolco]

Hey John, Thanks for the cool letter and suggestion. Couldn't leave that one on the table. Cheers, Tom

[@Popeye-yb3ct]

That was so cool! I've never even thought of making my own S hooks and such, until today. Thanks.

[@gigabytex64]

I love you always give out metric. I am Australian but I do have American citizenship as I lived over there in Youngstown Ohio but I really struggled with imperial, the fractions like 1/2", 9/16 and so on are easy as I was a mechanic so they get picked up easy but when I get to the decimal fractions in size I get confused easy. I trained over the years to be an Auto Electrician, Mechanic, Auto Body work, Computer tech, Programmer and a general labor worker and that's what got me in the end as I was 3 floors up pouring rain on scaffolding with a wheelbarrow slipped and fell 3 floor clipped my neck on the way down, now you might think I should be dead or paralyzed but I just crushed 2 vertebrae and over the years it's damaged my spine. I am lucky but ended my working life. I think I got allot done by my 40 years but now I got my little lathe and use my drill press with a 2 axis vice for milling and now learning from you Adam And Keith Rucker how to do the jobs I want to work on, my way of thinking is " You never stop learning unless you are dead or ignorant " and it's got me this far.

[@oxtoolco]

Hi Giga, Good words to live by. One of my sayings is "Learn everything you can about everything you can" Thanks for the comment. Cheers, Tom

[@phuzzz1]

Hey Tom, glad to see "the hand" is healing up nicely, all by itself...... Cool video, love the Tom-O-Meter too Mike

[@oxtoolco]

Hi Michael, As you know 3M scotch 33 electrical tape has some impressive healing qualities. Getting it to stick with way lube for blood is another story. Cheers, Tom

[@ericcorse]

Good test, the Oxtool bending jig is pretty neat too and a worth while project

[@VeradonaRestoration]

Super product, thanks for the video!

[@CompEdgeX2013]

Same idea as a carabiner. The bends are made to transfer more load off the screw-clip side and onto the solid half. Not so pretty but much stronger hook. Catchy title, I like it! Damn rod bender for the next copycat project I guess......it never ends! :-) Colin

[@pherdantler707]

Interesting experiment. Mr. Wizard is smiling down on you!

[@Buckrun11]

Now I want to make one of those benders for some reason. I liked the way it popped when you pulled the pegs out.

[@oxtoolco]

Hey Steve, That's a machinist's favorite sound. Piston fit. Cheers, Tom

[@Buckrun11]

Another goal to shoot for. The piston fit POP!

[@doubleboost]

Hi Tom Nice video The hooks are the same as a carabiner load next to the spine Regards John

[@w056007568]

Interesting demonstration regarding shapes.

[@Abom79]

Hey Tom, I noticed the Adam's Family hand chilling in the background. Kinda creepy looking. So what do I have to trade you for the Tom-O-Meter?? Enjoyed the test and tune. Thanks for sharing for us! Adam

[@adamtopper8220]

I need to make a bender like that someday when I get the time.

[@oxtoolco]

Hey Adam, Better load that Monarch up on a truck if you want the Tom-O-Meter. That is some fine equipment your looking at. Thanks for the comment buddy. ---Tom

[@RaysGarage]

Tom, I have 4000 pound mill you can test them on... Good test, and that's a very nice bender you made, well done! Thanks for sharing, Ray

[@oxtoolco]

Hey Ray, Bet they would drag that mill of yours out of the garage and onto my trailer. How about some action shots of the mill? Or is it just for show? Cheers, Tom

[@JohnBare747]

How to levitate a 1000 pound bench with a shop made hook and a very wily device called a Tom-O-Meter, that thing rocks, and the bench is bitchin' too.

[@oxtoolco]

Hey John, Mr wizard can use the force that the Jedi use as well. Try not. Do... or do not. There is no try. (Yoda) Cheers, Tom

[@JohnBare747]

Yoda knows all.

[@vigisbigtm]

Your bending machine looks great, and would work really well for me. Do you have the drawing for it and can I get them? :-)

[@outsidescrewball]

Hey Tom Smart on that handle angles for the bender!! Chuck

[@oxtoolco]

Hey Chuck, Just lucky again. Cheers, Tom

[@jtkilroy]

Ok, thats it, I am going to build one of those little benders! Might give a shot at a Tom-O-Matic scale as well.

[@oxtoolco]

Hey James, Better get busy. Lots of work to do in the shop. Cheers, Tom

[@jusb1066]

always enjoy some experimental tests

[@swarfrat311]

Hey Tom, Liked your experiment with the other types of hooks. I hope you didn't get bent out of shape since these designs work better than your "S" hooks! :-) Thanks for the video. Regards, Oxen Dave

[@oxtoolco]

Hey Dave, Well you have to be bent pretty far out of shape to do this kind of stuff anyway. The S hooks sure look better than big staples. Cheers, Tom

[@SBBlacksmith]

One of these days I will get around to making that rod bender. I guess I don't really have any excuses since our shop now has a lathe and mill.

[@oxtoolco]

Hey Kyle, You guys would just mess it up with red hot steel. Leave the cold bending to the professionals. All the best, Tom

[@SBBlacksmith]

Oooooooooooh..... So is that why the mill has been acting all funny? ;-) Keep up the great work.

[@kevinault9419]

Tom, I really like that bender. I just did a few models of it think im going to machine one up. I will send you the models when I get finished. That would give you more materials for your You tube

[@oxtoolco]

Hi Kevin, I already have it modeled up. The drawings are on my blog site. Thanks for the comment. Cheers, Tom

[@thomaslizon2594]

this is mind-bending!

[@lionmanyung4614]

Oxtoolco we like you're videos thank you

[@manudehanoi]

Hi Tom, The bender looks home made, if so what are the pins and roller made of ? It has to be something considerably stronger than the same sized cold rolled they bend.

[@oxtoolco]

Hi Manu, The pivot pin is made of A-2 tool steel. The sweep pin is a dowel pin with a O-1 steel roll on the outside. Cheers, Tom

[@manudehanoi]

oxtoolco thanks !

[@TheFixxxer11]

I like those bender, and i think I want to make one for myself , u got a video on making it?

[@miketownsend6108]

I like your tee on your handle; im going use your idea thanks

[@oxtoolco]

Hey Mike, I've been using that one for quite a few years now. Thanks for the comment. Cheers, Tom

[@12345NoNamesLeft]

Give us a drawing and a video or two, lets make that bender. & how about that cheater bar, I expected it to be long, not a T, that's pretty smart.

[@oxtoolco]

Hi No Names, The plans are on my blog for the printing. Not sure how far back it is. The tee is awesome. The short part is at a small angle and allows all kinds of weird positions. oxtool.blogspot.com Cheers, Tom

[@12345NoNamesLeft]

oxtoolco The blog link is here oxtool.blogspot.ca/2012/08/rod-bender.html

[@rchopp]

Thanks Tom, interesting as always.

[@oh8wingman]

You would increase the load bearing possibilities even if you were to make the small radius hooks with reverse bends similar to the "S" hook because the back of the hook would not deflect as much as the "C" design as the load is placed over the X or central axis of the shank. The tight radius hooks would also increase but the tight radius is not a good design for two reasons. First, the hooks are too tight to accommodate the slings properly and weaken the sling eyes. Second, the metal would have more of a tendency to crack in the bend are due to over stressing and upset in the metal grain structure from the way they were formed.

[@Opinionator52]

Bata Bing.... Nice steel, for also testing the nicely made bender! :o] O,

[@tom7601]

Interesting test! Tom - Vista, CA

[@danieltaylor9970]

Hi Tom, Will have to make some of these! Any shots of your overhead hoist/chain block, does it pivot on a pillar in the buildings frame or something? Dan

[@oxtoolco]

Hi Dan, Its a column mounted job crane that I built. Check out the shop tour video for some shots of it. Cheers, Tom

[@StraightThread]

An interesting experiment.

[@phooesnax]

I wonder if a ring where the sling attaches would improve it further? Nice...Not everyone has a meter named after them you know! Or hot and cold drinks for that matter.....Mr. Lipton

[@markifi]

it would be interesting to see the breaking strength of a 10 mm steel hook with the tight radius

[@AlexanderWeber_x_]

Great experiment! Can the design still be improved by closing the hook? And thanks for always pointing out the metric sizes. Appreciate that! Cheers, Alex

[@lastmanstandingwtsht]

Hi Tom would you share the build details on your rod bender ? very nice compact design. I suppose we could work out a royalty agreement on my next 500 piece run LOL -cheers

[@cpcoark]

do a utube search on oxtool bender. Don Corssitt did a video on making one. Also Tom covers it on his blog site.

[@rskyes]

Tom, just curious. Can you put your new hooks back into your bender and see where the hooks reference back to compared to the previous marks.

[@oxtoolco]

To see if they yielded? The resolution of the mark is not that great and there is springback when they are bent. It would be best to measure some spot and record it to check for distortion. Cheers Tom

[@17hmr243]

The 2 new hooks with opposite hook sides like the s shape. Would that change the load?

[@tittlek]

So I'm curious, your table seems to be pretty close to 1,000 lbs. Did you design the cutouts exactly so it weighed just that much, or was it just a happy accident?

[@oxtoolco]

Hey Kent, I Weighed less when I first made it. Then I added the rail and two vises and viola! its nearly exactly 1000lbs. Total happy accident. Cheers, Tom

[@aserta]

There was no contest here. Smaller radius = bigger load. I bet that if you'd make them smaller in the shaft area the bow would be nonexistent practically. If you look at the hooks Nasa used back in the day to transport equipment off the lander and to the astronaut you can see the same philosophy. Even if they never needed it since Moon gravity is lesser than the Earth counterpart. Reason being that they had to test all of this equipment here before they let them use it there so it had to withstand our gravitational pull to pass. Different applications of course, but my point is they chose the higher load bearing one but that could snag over the one that would not snag but didn't carry as much.

[@oxtoolco]

Hey Aserta, I agree not much surprise here. If I could load test them to failure then that would be interesting as it looks like these could go much higher. I just don't want to have my crane land on my head. Cheers, Tom

[@aserta]

oxtoolco (to be proper and respond in kind :) ) Hey Mr. Lipton, Yeah. I guess there's no way to safely test them and anyways for the purposes at hand i believe this test suffices. If i were to take a shot in the dark i'd say each of those two can at least take twice the tested load or there about. The shorter of the two might even take more, since it barely seemed to bow out when compared to the longer counterpart. Either way, these are nice designs and for moving regular shop item B from one spot to another it believe these would suffice to anyone. Have you done a video on your shop crane setup? If not and you find yourself lacking a subject that would be a nice little segment. P.S. any relation to Thomas Lipton? I was searching your name to make sure i wasn't going wrong about it, being new here and all that, and i stumbled upon the Wikipedia of this Sir Thomas Lipton. Interesting name coincidence none the less. Cheers, Andrew

[@TheMyriddin]

Very interesting! How did you create your gauge so that it calibrated so well? Meaning how did you get the 100 lbs per dial unit (0.001"?)

[@oxtoolco]

Hey Walter, It was pure luck. We calibrated the gauge on several proof loads and were surprised and happy to find it was some even division. Cheers, Tom

[@tolikp]

Hi do you have a video or plans for the bending jig?

[@Ricopolico]

PS - NICE bender! Rich

[@bx2200]

Hi Tom, If you heated the rod red hot with a torch before bending it, how would the strength of the hot-bent hook compare with that of a cold bent hook? Would they be different? Thanks, -Chris

[@oxtoolco]

Hi Chris, We did that before. We tested some blacksmith forged hooks and they weren't quite as strong as the cold bent hooks. Cheers, Tom

[@skippy1460]

LOL the look like used staples. no offense Mr.Tom it was the first thing that came to mind

[@oxtoolco]

Hey Tristan, Big honking staples I might add. Cheers, Tom

[@skippy1460]

what might be the size of the stapler that made those.:)

[@binks166]

hello, my name is harvey and i have a meager machine shop in my back yard garage. caught the mechanical/machine tool disease in high school and have loved it since. way cool bending tool,, bet you made it,. also like your belt sander. do you have drawings you might share? thank you,, harvey from nebraska

[@oxtoolco]

Hi Harvey, Thanks for the comment. The plans for the bender are on my blog website. oxtool.blogspot.com You will have to go back a ways to find them. All the best, Tom

[@esoomreltna]

Tom, On the bending jig I noticed that no lube was used on the bent rods. Is that the usual approach?(I know jack squat about such things) Eric

[@oxtoolco]

Hey Eric, For bending like this with a rolling element lube doesn't help much. Where you see some benefit is things like tube bending where there are a lot of things sliding against one another. Now you have squat. Cheers, Tom

[@esoomreltna]

Ahh because the forming rollers move on the jig...got it! Thanks.

[@erikdevaney4781]

i dont see that the table is bolted to the flooring as well as no shake/wiggle or sliding. is the table plate atleast 2" thick???

[@oxtoolco]

Hi Erik, That table is only 1.5 inches thick. Thanks for the comment. Cheers, Tom

[@conawayjb]

Have you tested the forged s hook that a viewer sent you yet?

[@miles11we]

wont your straps fail signifigantly earlier when they are not sitting flat and perpendicular to the load? i was going to say that the two tight hooks are pretty much identical as far as the load is concerned but yeah.. if you wanted the most out of the strap and hook wouldnt putting an overkill ring between them be best so the weight on the hook could be as close to the vertical section of the hook (putting it in tension without making it want to deflect) while also allowing the strap to be happy and "flat"

[@oxtoolco]

Hi Miles, The slings in this case are significantly stronger that the hooks under test. You are correct to get the most out of the sling you should have nice and flat. This is not always possible which is why lifting gear has a large factor of safety. Thanks for the comment. Cheers, Tom

[@manikandanej2665]

Miles11we

[@robmckennie4203]

What's the story with Tom's table there? The holes don't seem to have any particular rhyme or reason to them, used stock from a cutting place?

[@Bookerb2004]

Thanks Tom, That table is very interesting can you touch upon the design of that monster, I notice several indentations, holes, angles.. etc etc I know there must have been intentions behind them, do you have a video of its making?

[@oxtoolco]

Hey Kelley, Now I know you haven't watched all my video's. This pains me greatly. Your homework assignment is to watch all my video's starting at #1. The table review is in the shop tour video in case your wondering. Cheers, Tom

[@Bookerb2004]

I'm on it Tom :)

[@Bookerb2004]

Hmmm I cannot seem to find that video Tom ;(

[@oxtoolco]

Kelly Breckenridge OX tools shop tour. Use the little magnifying glass search Icon. Best, Tom

[@Bookerb2004]

Sorry Tom I YT off an iPad most of the time & the KZbin Apps provided for some Apple products suck big time, no searching allowed Google & Apple just don't get along If I sign out of you tube & use my browser I should be able to find it but then I can't comment under my handle ;( But if I use my Mac no problem, but hey it's really far away man

[@pierresgarage2687]

Hi Tom, To bring the hook to failure without getting the crane on the head, just use smaller diameter rod, and please put your right foot under the 1000 pounds table to match your fake hand and maybe this time we wont get so scared seeing your foot being crushed.... And please wear sandals without socks...! Thanks again, Pierre P.S. Were you ever talking about publishing some drawings of your famous Tom'O'Meter?

[@oxtoolco]

Hi Pierre, I thought of a way to take the alternate design hooks to a much higher load and not kill myself in the process. Stay tuned as it may show up in a meatloaf as a short segment. Cheers, Tom

[@pierresgarage2687]

Hi Tom, Cool, love that kind of stuff. Take care, we'd miss you if something was to hurt you. Pierre

[@LauriLevola]

Minor detail: would it be better if you put your mic to manual gain, so that clanging tool didn't diminish your voice for a brief moment while the auto gain readjusts? Spikes could be clipped during editing. But thanks for great vids!

[@oxtoolco]

Hi Lauri, The mic is in the camera and actually does pretty good. I don't think I have an adjustment for that but I'll look. Thanks for the suggestion. Cheers, Tom

[@terrycannon570]

How much can the Tom-O-Meter take ?

[@Crawlerjamie]

This is boring. But soothing. Because clean fabrication is so enjoyable.

[@AlexIliev]

Is there a way to buy the bending jig? It looks fantastic, and it would be nice to support the guy who designed the whole thing.

[@oxtoolco]

Hi Alex, I don't make the rod bender for sale. I have the plans up on my blog site for anybody to build one. Thanks for the comment. Cheers, Tom

[@AmateurRedneckWorkshop]

That was sort of a surprise as I expected them to all perform just like the S did. Do you ever go home at night? I have made some videos and they take hours for the editing and rendering even after you record the action.

[@Keith_Ward]

These hooks are stronger since the load bearing points are nearly in-line with the stock itself. It allows them more easily approach the tensile strength rather than bending the hooks out.

[@oxtoolco]

As you know I'm a machine that looks like Tom. He is watching TV right now. Cheers, Tom

[@rohitchaudhari4560]

Sir plish s huck Dye making power presh But nothing's to plish tools making 🙁

[@irish-simon]

small question does dynamometer have to be recalibrated does it not deform ?

[@DominicMuren]

Simon, it seems like as long as you don't exceed the elastic deformation regime of the frame metal (steel?) then there would be, by definition, no permanent (plastic) deformation. And, since most metals have a generous elastic deformation range (they are "springy") these very small deformations probably don't exceed that.

[@irish-simon]

Thanks I really enjoy your videos I learned something every time 27 years in the trade and thankfully still enjoying learning new things Thanks Simon

[@oxtoolco]

Hi Simon, The dynamometer operates in the elastic range of the material. So its like a big spring. As long as you don't overload it the spring returns to the starting point. When you calculate the allowable stress you make sure you don't approach the point where the material will yield. Thanks for the comment. Cheers, Tom

[@timothybarron1077]

now measure the thickness on the straight portion to see if it thinned out. I predict failure would be in that portion of the design.

[@oxtoolco]

Hey Tim, we didn't get close to yield in the straight section. That would be something like nine tons to start seeing necking. Thanks for the comment. Cheers, Tom

[@timothybarron1077]

oxtoolco That's good info for somebody trying this at the home shop. It lets people know there's more to it than just bending up some bar and having at it! Good stuff! enjoy every vid! Thanks!

[@luizcarlosarrudajunior3402]

Cópula you show us your "wire" bender?

[@oxtoolco]

Hi Luiz, Kind of large wire in this case. Thanks for the comment. Cheers, Tom

[@rezganger]

U could probably make it as a "Z" shape if u dont like the "C" shape.Its the same,I think.

[@derwissenskiosk8041]

This is a heavy table.?

[@oxtoolco]

Yes. Approx 460Kg. Thanks for the comment. Cheers, Tom

[@bobdouglasssr.3864]

How about you rebuild the rod bender, so we could do it with you?

[@oxtoolco]

Hi Biob, Don Cossit built one from the plans available on my blog. Sorry I already have two of them. Cheers, Tom

[@swaffy101]

Is there any planes for the bender?

[@oxtoolco]

Hi Swaffy, Check my blog site for the plans. oxtool.blogspot.com You will have to go back a ways to find them. Cheers, Tom

[@swaffy101]

thank you sir!

[@allisonyoesful]

... can we see the s-hook now??

[@jorgeconcheyro]

Hi Tom!! Love all of your videos, they remind me my days in high school threading with the lathe, and creating helicoidal gears on the mill. I see you struggle with a rule at 5:48 and it reminds me that Adam uses a steel rule hook (never saw one, I found the name on Amazon) and I would love to give you one as a gift, but unfortunatelly our goverment is overcharging overseas purchases... So I can only give you the idea or maybe +Abom79 would give you one of his. Thanks both of you and Adam for the videos, greetings from Buenos Aires, George.

[@oxtoolco]

Hi Jorge, Thank for the comment and offer of a ruler. I have a bunch of hook rules so I'm all set. Glad you like the show. Cheers, Tom

[@aliafreet]

Greetings, my brother, I want you to buy rolling machine price

[@nangidkram8652]

My money's on the 'S' hooks being more aligned with the natural order of things akin to harmony. What if the load is vibrating or knocked? Nice try nice vid nice tooling.

[@tylercunningham3275]

Do I see a Rockwell hardness tester back there?

[@oxtoolco]

Hi Tyler, Not yet. Not sure what your looking at. Give me a timestamp. Cheers, Tom

[@tylercunningham3275]

11:02 directly behind the tom-o-meter on the floor.

[@oxtoolco]

Tyler Cunningham That's the rear cover off my lathe. Its a big aluminum casting. Cheers, Tom

[@Ricopolico]

So, Tom, that's a 6 inch scale you carry in your breast pocket - from watching your other videos I thought it was a scraper. Rich

[@oxtoolco]

Hey Rich, You mean my scraper that happens to have graduations on it? That one is twenty five years old and its still fine. Might need to touch up the edge a little if I need to cut some doughnuts in half. Cheers, Tom

[@nangidkram8652]

Ha! My subsequent like took 666 to 667. Begone Satan!
