The aspect of “need a tool, make a tool” was always something I enjoyed about metal working.
How in the hell could anyone give this a thumbs down? This man is gold. Thank you for sharing!
Thank you very much for your support
@@mrpete222 Yes! This is so educational and information not readily come by on the internet. Seems like this can only be learnt from those who've been around!
They prolly thought there was some slick trick to get a drill to do a square hole. It is what he h advertised; "Drill a square hole." Maybe they just don't get his sense of humor.
@@Raul28153 : More than one way to skin One.
Maybe because he goes on and on at the start. We know what he should be trying do from the title, Or else we wouldn't be here.
Crafty old fox technique here. I never thought of forming a square or rectangle in round stock with this method. If it was silver soldered or brazed it would have near as much integrity as if made from a solid piece. Today,I found myself enlightened by an old school shop teacher👏👏
Silver soldering is a great idea. I think I would widen the slot width above the 1/4" square opening to 0.315" for a 0.312" filler blank. EDIT 1: The 1/32 land on each side establishes the 1/4 opening, any silver solder closing the opening would need to be filed away (silver solder tends to fillet radius sharp corners and gaps per your supplies and torch skills). EDIT 2: A dovetailed filler slot could be endmilled above the 1/4" opening with a reverse taper one lunger cutter for silver soldering a dovetail filler piece. Any sidewall could be drilled and tapped into the 1/4" opening for a setscrew(s).
No cross pins, HSS blank or aluminum shim would be would be required.
This procedure could be used to form an opening across the diameter with a 1/4" wide slitting cutter in a Bridgeport. Shop made boring bar?
@@waynespyker5731 I think the technique I'd use would be raise the end mill to half depth in the slot and machine an extra few thou from either side of the slot. That gives you the ideal gap for braze/silver solder fillet but leaves the lower half the slot tight on the insert piece for accurate location. It would also prevent any silver solder from running through into the square hole area.
I love watching old timers teach neat tricks. It’s alway enjoyable to watch someone who is passionate about their trade!!!
Thank you very much
I am a remedial machinist - it's obvious this guy is a master. Thanks for the great tutorial !
That Rose Index looks like a tool that an apprentice machinist would be requited to make while learning skills. They would ultimately add this item to their tool collection and use over their entire career.
Thanks. I miss machining. I did it in High School and for a few years, I had a friend that had a machine shop in his basement but he has since passed away. I was a lathe operator for 11 months after I got out of high school but decided to change my profession and became an HVAC technician. I always loved machining and miss it. I really enjoyed watching you do this project. Thanks again.
Well now I know what a Rose index is and how to use it! great idea, and even at 78 I'm still learning things thank you for taking the time to show us young'ins a thing or two. "Whats that old adage, "You're never too old to learn" I just proved that. thanks again.
As a long retired machinist, we never had a "rose index", we had to make do with a V block and angle gauges.
I love being a machinist for 26yrs and watching tricks from older machinists at our shop we tell the young guys to never make a man mad at you because he'll never show you any of his tricks!
FOR SURE...use copper when removing a broken bolt/stud in metal piece, around and inside the hole....then , mig weld to the stud, (slowest rate) and remove. copper wont weld.....and separates the main metal, from the arc.....
...there are so many Methods in in this Job - you could never learn enough from the older Machinists! 👍🏻
If only we all had shop teachers like this.
No kidding.
I took machining courses in Jr. College and had seasoned instructors like this guy. I only worked as a machinist for 2 years then quit because my boss was such an a hole and I believed the whole industry would be like my boss.
Great. Now I have to buy a Rose Index.
I thought the same thing.
Make a Rose indexer. Pretty simple machining project.
Or just use a v-block
@@rstebb311 that is fine for this project where you only nee 90deg, but the Rose gives you 30, 45, 60 & 90deg.
On my shopping list. nice tool.
Thanks, Mr. Pete especially for the introduction to the Rose Index, I must have one.
Dear Mr. Pete
This video was my very first of your channel. I say that it is my very first in the sense that I have just begun to Learn metalworking and machining after a long career in medicine. I find it to be absolutely an art of precision and of patients/patience. I truly find it fascinating to be able to create something and I find it extremely soothing and truly do appreciate the time you take to put into your videos to help novices is like myself.
Thank you so much for your quality content
Cheers
Mike from Philadelphia
Thank you for watching. Enjoy your new craft
Best shop teacher ever. Period!
Thank you very much
I loved how you started the video with "you can buy a $150 broach or use this method", then ended the video with "you can build this with twenty thousand dollars worth of machinery or just buy a $150 broach"
Pure contradiction in turn. Why spend $150 when you can do it for less! But, you need to spend $20K on machinery first to do it! That sounds a bit Irish to me. So go and buy a $150 broach instead giving you a saving of 19,850 a bargain
A rose index costs $149 - same price as the broach
I saw the video pop up and right away i thought you would drill it and broach it. I never really thought of doing it this way to be honest about it.
Just another way to skin a cat. Knowledge is good.
@@andyg.8971 But so very useful for so many other things, have struggled in the past making square square pins this would have made things a lot easyer, and accurate.
I never would have thought to do it this way thank you Mr Pete I thought I have to spend hundreds.
Old machinists trick. A lost art. Thank you for reminding me of this!
Yep. Those "Old Machinist's" were a "Tricky Lot". One thing my dad, "They call me a 'Tool Maker', but not by 'East Coast' standards" said [we're from New England] at the shop in Santa Monica, Ca in '62 was that if you walked away from the machine, back off a 0.001" before you start in again because everything has cooled down and changed dimensions. He did this on an old, non-numerical read out, manual (dial only) Bridgeport Mill and could work +0.00003"/0.0000.0" tolerances all day long.
Always nice to see true craftsmanship in action ! I just ❤️ it !
The good old "oldtimers". Back then i learned a lot from them during my apprenticeship to become a tool and die maker. This one is new though.
That Rose Index, would be a pretty decent shop project. Would work in lots of places that a hex collet holder would not.. Good video.
Good shop project for students-they walk away from class with something useful.
It’s patented. The inventor commented above.
@@G58 Still, patents don't limit someone from making one for his own private use. It protects against other people monitizing the idea. That does indeed rule out a lot of users, but just saying. And whilst I give cudos to the inventor, when I saw it in the video I was sure that tool was a really old one. It's mind buggling that in the world of machining this no one has come up with this earlier.
@@G58 that doesn't prevent you from making a copy for yourself - only from selling them.
This is a great video, you are the best teacher. I loved this process...
at the mature age of 57 years old i have never had an idol in my life but mrpete would qualify as a potential candidate, he is a pot of gold of fabrication knowledge.
Thank you very very much
That was a clever solution for when you don't have access to a broach, thank you I appreciate the lesson. Enjoyed it very much!
Great way to do it! I would use silver solder it to give similar strength to a broached part. One big advantage of the demonstrated technique is that it works for odd dimensions and bottom holes. Silver solder is one of my favorite materials when building prototypes. Also this way may actually be easier than broaching or odd geometries such as angled holes.
Regarding the loctite on the inner surfaces of the insert. That would actually help pretty substantially. As a general rule (or so my mechanical engineering professors told me), adhesives are most effective in compression and shear stress scenarios, but less so in tension. Trying to slide that insert out would be pure shear which would be among the ideal scenarios for an adhesive. Additionally, all that extra surface area would distribute the force too (meaning less shear stress) thus it would take even more force to break it out.
This was a very informative video. Thanks for showing the Rose Index. This is a terrific solution. I can only imagine how many other types of tools can be made by leveraging the concepts that you just showed us. You are a wonderful shop teacher... so keep up the good work. Cheers for an excellent video... It was very interesting (definitely NOT boring)
Mr pete. Love your channel. I have been machining for nearly 40 years and i still learn some things from you. You have a great honest and no nonsense approach. Thanks for taking the time to do this type of education.
👍👍👍
Thanks for posting this! You've opened my eyes to something I've never really thought about. I can see LOTS of uses for this type of machine work. Mainly tool making!
that is really something cool mr pete im glad you showed us that
Timm thank you for the video. I am a 1 year in fabricator and you just showed me more in these minutes than I have learned about our mill this whole last year. Thank you and you have a new subscriber. I look forward to more of your videos, stay safe.
CmdrMoros
This video was made by Mr. Pete. I'm just the guy who made the block he used in his video. Mr. Pete is the teacher that disserves your kind words.
Sir: I know nothing about machine shop work, & I had NO idea how you were going to accomplish the making of the 1/4 inch hole. What a marvelous education I got ! Thank you ! As my late grandfather would say " When you know NOTHING, it isn't hard to learn something. A great video Sir !
That is a very cool idea and implementation.
Loved the trick! I'll probably find a good use for it too :)
That was a brilliant way of machining a square hole
Watching Mr Pete for all these years, I have become convinced that it would take me TWO LIFETIMES - at least - of learning and training to barely get to shouting distance of Mr Pete. You are a LION sir ! Thank you once more, cheers.
Thank you very much
This was one of the most ingenious shop videos I have ever seen! In particular, I loved the Rose gage!
Thank you very much, it almost went viral
@mrpete222 I think it did go viral! Tons of chatter found on hobbyist web sites about this one!
Wow, around the block twice , two county fairs and one dog and pony show , but never seen a Rose Index . 🤔 . Gotta have one now .
Excellent, I learned a new technique with my morning coffee
Great to see your videos again. Such knowledge. Every kid would have loved metal work with a teacher like you.
The days when metal and woodwork teachers were retired craftsmen are long gone. Our woodwork teacher was a 77 year old retired cabinet maker.
His lessons were awesome and no one played him up, possibly because standing in the corner would probably have involved our arm being clamped in a vice. 😊
That was a really neat technique for getting a square hole! Thanks for sharing it. Cheers! 👍👍
Well done Mr Pete. One to keep in the back of my mind for sure.
Dude this was excellent! I learned so much in such a short amount of time!
Solving complicated issue with a most simple way. This is really fantastic, and a real talent.
Wow , I just love watching these old timers , as my dad would have said, there's always more than one way to skin a cat. That is the most clever way to tackle that job without a square broach.
Made a wrench for my small acetylene tank like that when I was young and broke. Gas welded the slug in. Nowadays I'd just buy one.
Our drills always make something that resembles a triangle.
I like very much the new transition
Great video Mr. Pete, it makes me think of my 9th grade wood shop teacher showing me how to make a chess board for my very first self designed project. In that case he had me glue alternating strips of walnut and maple together that we later planed flat and then cut in strips. In my 9th grade mind I was amazed as I had visions of cutting lots of squares and gluing them together.
I liked that tip. All of these simpler processes held in memory can be combined and recombined to provide understanding of much more complex procedures. Before you know it, you’re an older person dispensing wisdom to eager young apprentices via the internet. You are a solid gold asset Mr Pete. 😎👍
Thank you
Saving of money and time to get a broach for this job Hands off to you sir i am from india.
He explicitly commented on doing this instead of purchasing the relatively expensive broach for a one-time use. It all comes down to how much your time is worth, and how long it would take you to do this, versus buying the broaching equipment. For a lot of home shops, this method makes a lot more sense, even if it does take longer and more work.
I've never seen a Rose Index before and now I want one. Thanks, Mr. Pete! :-)
I want one and don't even need one!
JIM
Nice work. Love learning new tricks for the mill. Was totally not sure how you were going to do that, but great job teaching the technique!
I now know what a rose index is. Of course the manufactures and retailers of rose indexes never make videos like these for the public and they are supposed to be the ones that inform the public about their products. Thanks for doing what they should do.
Great work Timm, you remind me of my dad where he tought me a lot about machining, look forward to more. BTW, you just cost me $149 dollars, I just purchased a rose index, haha, great tool to have in your box :-) thank you again
Thank you for the kind words. It means alot. The 2" inventory will probably be used up in a week, however I'm gearing up for another batch of parts. There are still plenty of 1" models available. I look forward to future comments from you and others.......I want to hear if you still feel as if I cost you some money, or if your acquisition was a valuable purchase and you'd happily do it again.
Be well and thank you
Enjoyed that one sir. That rose Index is never seen, looks very handy
Back in the 1940s it would have been great I’m sure
Awesome video and idea!!! Thank you I will use this idea for a project. Was just looking at broaches for 1 job, this saved me a bunch of money!
As always Sir, an excellent process to give an alternate solution that I had never thought of. Many thanks from AUS
Hey Mr. Pete!
One suggestion for pinning the filler material into place... Use mild steel taper pins driven home firmly with the Loctite.
Ken
Either way, it's the same principle as "Draw Boring" in woodworking used 14th century through early 20th century solid furniture - most noticeable in "Craftsman", or Mission Style" furniture.
Thanks Mr.Pete, great project. Never heard of the Rose-Index and went to find one and it’s around $150, same as a broach, doh!
This is great and as Mr Pete says can be varied to meet a lot of different sizes and shapes. Awesome...many thanks
I REALISE THIS VIDEO IS NOT THAT NEW,BUT MR PETE,YOU NEVER CEASE TO AMAZE AND IMPRESS!!
I AS THINKING ABOUT SIX DIFFERENT DIRECTIONS. I MUST CONFESS,I DIDNT THINK OF HOW YOU ACTUALLY DID THIS ...
WELL DONE!
IM NOT A MACHINIS. I DID SPEND NEARLY 25 YEARS AS A CERTIFIED WELDER/IRONWORKER AND CUSTOM SHOP FABRICATION. THERE ARE SOME VERY TALENTED INDIVIDUALS AND LITERALLY JAW DROPPING TRICKS,IF ONE IS WILLING TO APPLY THEMSELVES!!
YOUR VIDEOS ARE ALMOST ALWAYS VERY INTERESTING AND YOUR WRY,DRY SENSE OF HUMOR IS A HUGE BONUS!!
THANKS SO MUCH FOR LETTING US HAVE A PEEP IN YOUR LITTLE CORNER OF THE SHOP!!
👍👍👍
Great instructional video, Mr. Pete. There aren't many of you old machinists left; great that you're sharing your time, talent, and expertise. Its a shame that kids nowadays do not appreciate the learning experience of somethin like this. It teaches, math, planning and execution to accomplish this.
Thank you very much
I agree. Taking the time to share your experience is important.
The world has changed so much and as a person who went down a path not many people choose makes it difficult to express how much I am thankful for patiently explaining your thought process.
Never stop sharing your work....please.
May I say - Mr Pete is not an old machinist, he is timeless! And we thank him for his teaching.
Great project Mr. Pete...Like it. I looked up the phrase "well used" in the dictionary, and it showed a picture of your Loc-Tite bottle lol! 👍✔💯
That rose fixture would be a good project to make.Thanks for sharing this video with us😁😁
Thanks, Mr. P. I always learn useful things watching your channel.
I’ve never seen a Rose Index. Thanks!
Excellent idea, that.
I once did something similar with a simple clamp, but this is much better.
I had a sneaking suspicion this is how you would tackle something like this. The Rose Index is a super nifty tool, even a good beginning machining project too.
And I thought I knew it all... and then you show the Rose Index. Thanks for the video!
Dear Mr Pete, I just found your channel. What a joy to watch you work, I subscribed for sure. Thank you, Jim
Finally, a place for that square peg.
No, that's a square hole in a round peg!
Round peg in square hole works better than square peg in round hole. ;D
That was such a great video. Why didn't I think of that? Take care.
Good one Mr. Pete....very informative and useful. Nice to see you machining again
Oh jeez I love this guy!
Well here goes the internet, about to get mined for Rose Indexes all of a sudden.
G’day Mr Pete. What’s that saying, “ can’t see the forest for the trees” well my thought process was on a rotary broach and when you started milling the slot the penny dropped to what you were up to. I would have forgotten to add the shim for wiggle room for the tool, well done. The Rose thingy looks to be a good shop project, it’s now on my list to do, thanks. I enjoyed the video, thanks.
Cheers
Peter
god bless this Men i wish he was my friend when i was 12
Why am I watching this... But I can't stop either
Mr. Pete, these videos are amazing. Documenting a lot of information that MAYBE get's personally handed down to a few people, you are opening this information up to everyone! Thank you so much for taking the time to do this! Subscribed, and look forward to more!
I've been trying to put square pegs in round holes since I was a kid!
This is a fantastic technique. thank you for showing us this!
That takes me back to 1964, when I began my engineering apprenticeship. I am retired now but engineering is such an amazing subject.
I've never seen a rose index before. I'm going to have to make one of those.
Yes, I'll have to make one also. I didn't know about the Rose Index until now, but what a useful tool it will be. BTW, Loctite will set up in less than ten minutes with a little heat from a hair dryer and if already set up, about 200 degrees from a torch will loosen the bond to allow the part to be removed.
Seems like it would be handy to have an indexer to make one.
I bought my wife a broach and she wears it all the time.
I practice broaching with my wife for many years now. Not nearly as often as earlier on.
@@RRaucina so she has a square hole now?

never had a chance tolearn any of tis, but i love watching somebody proficient at thier trade work, especially watching someone make something out of thin air. thanks for the show Mr. Pete C-ya again
Thanks
That rose index is brilliant! Think i will make one for woodworking. Thanks for sharing.
Nice job, next time when you edge find go from the rigid jaw you will find it more accurate and once you find the jaw you can use your zero for quite awhile,
you could also use a 1/8 endmill to spot for the holes then use a 1/8 pin with a slight straight knurl and just press fit in place and forget the locktite, if you are going to use it for holding a cutting tool the locktite can come loose from the heat and that won't be good. Just passing on some of my over 50 years of machine shop knowledge
Making an internal key way could possibly be done using this approach. Those tools cost a lot, are limited to just one width of the key way, calls for a good press tool and are seldomly used. Thanks!
Thanks for demo Pete.
Thanks for sharing your intelligence and experience.
Great knowledge on machining a square hole. Thanks for the Rose Index tip!
Good video. How about making one of those indexers
It’s patented. The inventor commented above
@@G58 So what? Perfectly legal to make one yourself.
@@JohnJones-oy3md Actually that isn't true. law.stackexchange.com/questions/24148/can-i-build-something-for-personal-use-if-it-is-patented#:~:text=In%20the%20US%2C%20if%20you,enough%20to%20qualify%20as%20infringement.
However, in reality if you don't tell anyone about it then no one would ever know. It's not the honorable or right thing to do, but you're the one that has to look in the mirror. It's not like they're that expensive.
Another tip for indexing the part: mill a small flat at the end. Use your square still. After features are done then machine the flat off.
Very good tip!
Why not just rotate the shaft and use your square on the edges of the groove you just cut.
@@madjack3314 that would work as well.
I’ve never seen a Rose Index before! What a great invention!
Looks like I’m not alone about the rose index. The tool holder is a neat looking project. Thanks Mr Pete
Could you do a Video on how to make a Broach from Tool Steel?
“Here’s how to save yourself $130 as well as honing your machine shop talents…” inspired, Sir!
I love how a good engineer has a ‘toolbox’ of ideas on how to solve a problem .... that’s makes engineering fascinating. I’m actually an electronics engineer but from time to time, mechanical engineering knowledge is very much an essential ally when constructing a project. From an electronics point of view, mechanical is very much the bedfellow.
👍👍
Nice to see the heat carried away by the chip. Great job! My best tools for fine work were always ground out of cobalt steel stock. But I liked carbide for hogging metal out.
How about a project to make a Rose-Index?
Almost too easy. Someone needs to do the cad pattern and then it could be 3D printed and cast in aluminum.
@@danharold3087 I could draw it up in no time put a thread insert in it and just use it as a plastic part! Why not? It don’t take any forces!! I’ll draw it up! And print one out!
