- Another way to drill the hole in perfect center through the round shape bar.
I use 12mm brass bar just to show you the process. this method is good if you heave to drill more same parts, just use harder material for lead.

I know a lot of people scoff at this vid, but they should realise that just because they have knowledge, does not mean that everybody has. and people like me appreciate someone giving their time to help out others. I have tried it myself, but you tube did not work out for me.
I did my time as a tool maker back in the early 70's, but gave it all up as the money was rubbish in those days, and so became a builder. Now in my 70's,
I have aquired a small old metal lathe and milling machine, with all the tools I could wish for, and I have not got a clue how to use them. It's true what they say, use it or loose it. Now i'm getting tips from you tube to get by. Thanks for the vid, very helpful.
Great to hear but i don't agree with your word "use it or loose it" i collect the tools even if i need only here and there, tool.is always good to heave and there is never enough 😅
A rod will not deform as much as a hollow pipe, especially if you use care. And a brad bit would not tend to slide off. Do it slowly and carefully.
Thank you. Finally, 3 minutes of UA-cam video that I will remember and use from now on.
Tintek33, for several years I used to install and overhaul General Electric Co. gas turbine generator sets in the 20 to 60 Megawatt range in the absolute armpits of the world. Proper tools, jigs, fixtures were very seldom available and we had to use our wits to come up with solutions to dozens of problems every day. Sometimes a simple dial indicator was unavailable for 2-3 weeks or more. In Venezuela it was a 4 hour drive to get a pack of hack saw blades from our location. We had bamboo ladders in Taiwan, hardly OSHA approved.
We had an occasional Field Engineer who insisted on holding diesel injector pump tolerances for roofing nails.....that's fine for a government funded Precision Prototype Aerospace Lab but not for our situation. I replaced several prima donnas on various assignments that were lagging. The goal was to get the power to the grid as soon as possible, no excuses.
I built a lot of lifting fixtures, jigs, special one time use tools right there on job sites using the universally available oxy acetylene tanks, 9'' body grinder, and welding machine, scrap steel. We always got these units up and running. Now I'm retired but still do small scale things in my garage as a hobbyist and appreciate videos like yours. Trust me....your video is not a ''disservice''.
+kimmer6 thanks
Great trick. Would be easy if EVERYBODY had a lathe in their shop
This was a very good example of how you can do this . Thank you. I've been a job shop/r&d machinist for over 40 years and I've never seen anyone use this method. Hence the saying " you are never too old to learn ". I also know from experience that if you give the same job to 10 different machinists, it will be done 10 different ways. They all get the job done, but not always so perfect. I clamp the round part in a mill vise and touch off on the back jaw with an edge finder and zero the DRO (digital read out), then move the edge finder to the front vise jaw and touch. Then I divide that movement in half and then move the table to that dimension. I always spot the hole with a center drill slightly larger than the hole I want to drill otherwise, the other drill may walk . I know many peeps do not have a DRO on their home mills, but the same method can be used with your dials as long as you take in consideration the backlash.
I actually used your idea this afternoon drilling parts for my Pedal Steel Guitar... What a nifty Idea. I was a Tooling Engineer for the BOEING Airplane Company, we used steel bushings & CNC machines to do that work. Your idea helped me do it the old way, in my garage. Keep up the good work.
Mr BreakRAK thanks man
step 2, own a lathe....
Zactly. Unless the 'stick' (round bar) is too long.

where is the chuck safety guard.
John Brewer I've yet to see anyone with the guard on these mini lathes. I took mine off after the first turning because it just gets in the way and isn't needed. If you're responsible and use some common sense they're not needed.
Always one in every bloody video. I'm starting to think its the same person...
This is a good way of teaching people to think about a problem or figure out a method of getting a task done. good work.
Thanks
Enjoyed your video. I used to work for a precision engineering firm and the guys there were always coming up with solutions to machining problems. Using the cheap caliper to mark out made me chuckle. The trouble I'd have got in doing that!
Good example of one way to get a fairly accurate hole. There are many ways of doing this as there is equipment to do it. Accuracy fully depends on the projects end use. I have gone to both extremes, from drilling a hole using a hand drill in a vise to using my vertical mill with DRO, to dial indicating a part. But thanks for the video and your input. I always get ideas for sharing information.
Once you have a milling machine it's a lot easier to use an edge finder to pick up the edge of the round bar. Once you have the edge you can dial over 1/2 the diameter of the bar and use your center drill to start the hole. The center drill will start the hole in the correct location even on a curved surface. Once you have center drilled your hole location the regular drill bit will follow right through the hole started by the center drill. You should probably do a tutorial on using an edge finder and that would help everyone out quite a bit.
This is a very good idea to keep in mind when you don't have the right tool to do the job required. This is called IMPROVIZING for those who don't know. It is a great tips. For those that always say negative comments, most of the time, it is those who never do anything in the first place. All they do is criticize. Thanks for sharing.

Another nice practical way to solve a common problem.
Well intentioned and looks accurate enough for us.
Thanks for taking the trouble to share.
Much appreciate the stirling work. We thoroughly enjoyed watching this.
And BTW, don't pay much attention to the "peanut Gallery". Cynics and critics abound the world.

Thanks aRM
Good simple idea for more precise work than even using a DRO. I suppose one could make up a whole set of bushing for the rod sizes you use most. However for myself I will stay with the centering bit throughout. Then after the hole location in the bar has been established with the locating bushing then drill it to the desired size. The more I think about it the better it gets. Thank you for sharing.
A much simpler method, is to just drill a hole in the centre. BOSH, job done!
Yes, owning a lathe is a must here. But... this give some other ideas for us who don't have the "big" tools ;-)
That drilled piece can be handy and we can make some of different diameters we use at other people that have a lathe. Or, just try and make our best centered one and use it as a template.
So, it is a start idea for others to come.
I always love to try new things after i watch example videos on how to do something better.
Thanks man!
This is a common sense way to drill, I like it. Thanks.
Using the bush as a guide. Very smart. Thank you
Genius. I only "got it" towards the end. Very cool. Thank you.
Cleaver, I like it. Repeatable, quick, easy, nice one bud.
Thanks
use a 6" steel ruler lay it flat on round stock, touch and hold it with a centre drill. move the table left or right until ruler is level, remove ruler and drill
This method is not accurate
I like this method..... too get you close only though. My experience, it gets you within 5 to 10 thou.
You don't need a lathe. Instead of using round stock for your drill guide, use square or rectangular stock. Easy to set up in vice and drill your guide holes - you can even drill a number of holes of different diameters so that you have more than one drill size / hole option available for drilling through your round bar.
If you want to drill through centre of thicker round bar stock, simply put appropriate thickness shims either side of your square / rectangular "guide" in the vice to centre it over the round bar.
Very good. And it's so simple. Thanks for tip.
it is harder than one would think to drill a cross hole. In many cases it must be right dead on or it will not work. Your method is especially good if you have to drill many parts. MY only suggestion is that you should use a parrallel under the part, in the vice, just clear of the drill bit. It would make it easier to set up and more accurate as well.
No it's Not that hard I can do it in about 30 seconds using my Wilton Cross Slide Drill Press Vise. Chuck up the Round Stock bring the Split bit drill bit down close to the stock Crank the handle back and forth on the cross slide moving the drill bit down and the moment the bit touches the round stock thats the High Point "Center" Lock Down Your Vise and Drill. : )
Great tip, this would be good for keyway set up also.
Thanks for this video. I use the same method because I have a good mini lathe but a very bad drill press. It is an easy way to make multiple parts accurately.
Exactly, i shown on a mill because i don't got a drillpress in this workshop, this method is good for a drillpress wich center itself, thanks
That is certainly a good way to do it. Same principle could be used for other round materials that needed similarly centered hole. Cool.
Great Idea. I use Centre Punch and eyeball method.
With all due respect if that's ALL you use you won't get a hole accurately centered, period. Sometimes, "by eye" is good enough. But sometimes it simply isn't. If that hole is through a shaft, and a sleeve fits around the shaft, and a roll pin pins the sleeve to the shaft? I guarantee it won't be good enough. My eye is good to about .010. My DRO on the other hand is accurate to .00001.
Only God can do that within 5 decimal places.
prick punch
simple. I admire your genius.
Great video! Thanks for sharing this great idea....Realistically, you can just get a spacer of the same diameter as the rod you want to drill and then set everything up like you see at: 2:33 and drill through the spacer, as it will align everything for you.
Very clever. I will follow just this procedure next time I have to drill such a hole.
soooooooooooo,to dril a perfect center hole, i need a lathe and a mill???hihihih
And also why do you need that hole too?
Stefan Stamatov don't forget the drill press
I have the right tool for that purpose, and guess what? I paid only 99 cent plus tax for it, made in China, works amazingly.
No it doesnt.
What is this tool please?
I like this, and have the stuff to do it this way, thanks.
Brilliant idea & thanks for sharing.
@enginemaxcarb. Nope, but I can spell. Thanks for the caps, I feel honoured that a knuckle dragging moron would bestow me with such class!!!
Rule 1 of UA-cam: Don't put unnecessary, obnoxiously loud music in the foreground.
Andy Jones hy, really? so is better to listen a silence wit some machin voices? i don't speak englis so good to speak on camera. music i take from youtube audio library, i heave still much to learn.
Personally I'd much rather listen to the machine sounds than some annoying music. Not just because I find the music annoying but also because learning what sound the machine makes when performing certain operations could mean the difference between a successful operation or a scraped job. =/
Andy Jones ok, thanks, in my later video i drop music down for a moment to hear the machine for a moment and then back to music, sound cool to me (check the video how to make carbide insert fly cutter)
tintek33 Sounds good to me, I'll be sure to keep an eye out.
tintek33 what is the name of the music? I rather liked it
Note to those who are offering alternate ways to drill on center, including touching off the vise jaws with a known diameter tool...This is not about FINDING the center but rather HOLDING center as you begin to drill. Even after center drilling your location, a little drift is possible. You start on center but don't emerge on center on the opposite side.
What he's offering is a cheap drill jig to keep the drill bit on path by minimizing flex and drift, that's all. Not bad advice, though most home shops with drill presses will not have metal lathes, sad to say.
Anytime I hold two parts of "same" thickness in a machinist vice I always put a single piece of masking tape on the moving jaw contacting both parts and indicate from the solid jaw. The tape (or even a single piece of paper) will allow you to hold both pieces firmly because it compensates for VERY slightly non square jaws like yours or material that may be .002" or LESS different. This will prevent your guide from lifting or spinning and still give you an exact alignment.
Joe G great tip, thanks for that, simple and work well i think, i will try next time.
Nice tip. Thank you for sharing. :)
Simplicity is beautiful :-)
coooolllll! thanks for sharing. great idea.
Fkng outstanding!💗👏👏👏👍
Thanks for this! I've looking for solutions using different search terms and here I am. I'm working on a ~ .25 pin that needs a hole for a .125 cross pin. I'll just say with am older manual mill and the very small pin, most of the other "suggestions" also have downsides. I have been pondering a drill guide bushing, commercial ones are available, "but" they still have to be placed accurately. Last night I set center with a dial test indicator. My second attempt. If I get it wrong, I know what I'm going to do for my 4th. Thanks!
Actually one of fist comment that see a potencial of use this.
Also i never drill that way but just want to show another option...
Good info, thanks for posting.
well played sir well played .

Why not clamp a vee block in your vice, touch off either side of the bar using an edge finder, and drill using a self-centering 3xd drill, something decent, hss-e, short, and tin coated? Do you brass off your drills for this type of work? To save time, you could have even put the bar straight in the vice, your toolmaker's vixe has a small notch in the moving jaw for that; touch off the fixed jaw, and mic the bar, move accross half the bar width. You could see the drill flex as it entered the hole, picking up the non-hardened bushing, probably ending off at least .1 mm off centre. Sometimes if I need it really dead on, i'll pre-drill with an appropriately sized endmill to create a guide for the drill, if true position of the hole is important.
that is absolutely ingenious
you can use V-blcok, it's not expensive, check the ebay. it can handle any diameter.
The ebay?
@@TMPreRaff
Sure, the ebay. If you can't find it there, ask the Googles.
I can see why people are puzzled by this. If you have a machine shop, you don't need to do this, and if you don't have machine shop then you can't do it. To be fair it's a good idea if you had to give it to a junior machinist or labourer to pump out a number of holes consistently.
Mee, there is a simple made in china tool for that purpose, I have one for 3 deferent size of rods, drill holes on top, just fix the tool over the standard sizes of rod and make a hole from provided drill holes on top of that tool.
Mee Ibast
I would never have taught anyone to do this.
Fair enough guys. Just pointing out there is some logic here.
Dial indicator, edge finder, etc. to find center. Once you've done that, every other one is going to be centered, just don't move the dials.
brilliant idea..and thanks
Nice inspiration, thanks :)
thank you so much for helping to solve a problem I have had and same time how to build a hole guide for drilling straight holes with special diametres. $😁😁😁
Ottima soluzione, bravo.
That was excellent. I don't own a lathe but I can make it work brilliant.
the S W A G method is the go to tool for us that don't have a lathe
Thank you for a very helpfull machining tip, regards Doc Cox
Are you serious? Thank you for this kind of comment
Definitely serious and will be putting this into practise in the near future.
A bit convoluted but worthwhile to consider. Actually many drill vises have one prism jaw so then it will not work for sure. Also making bushes for anything but the smaller diameters will be costly and time consuming. There is a special tool which I forgot the name/ brand of but I'm sure it is Swiss and I think still available. Expensive though. Will post when I find it.
Brilliant, thanks for sharing a very good idea :)
No problem, thanks
Great idea. Thanks
Yup that helped! Thanks!
Very smart way
To all that are saying this video is not the best way to do the job.As the title said. This is another way to do it. We know there are other,and better ways, but this is simply another way.
Thanks god that someone understand
99.9% of the population appreciates your time and talent for demonstrating "another method..." Count me within that percentage. :)
Brilliant thanks.
Wonderfull Thanks !
you can also use a short drillbit. since longer ones tend to bend. and if you have to drill holes in a line on the rod. make a setup where you can move it across without moving it to the sides. and for marking a line you could use aluminium angle that fits the length of the rod. (since iron tends to be a out of angle more so than aluminium). and if you dont have any cnc machines you could take a metal plate and use a drill press meaure from the the hole you drilled in the plate to points you can hit on the drill press ( also measurements for the vice you are using) and use it for reference when setting up the rod.
I thought I might learn something. And I did. I learned I need to buy a lathe.
Unique and elaborate solution to a fairly simple problem. Seems if you had to buy a special tool or jig it would still be cheaper than buying a metal lathe.
Thanks that really helps
Thanks for the video
Excellent idea!
+René Merz thanks
Good job
Great idea
Good tip!
So the mystery is, buy a lot of tools and make it perfect using the tools you already would have needed anyway. That's a good piece of advice.
I rather enjoyed the cleverness in developing the center. The music was only a bit loud, but OK in selection.
Mr BreakRAK thanks, i take advice for next time.
You clever bastard that’s so simple! 😅😂
Very clever!
Nice trick...thanks
Nice tip
clever well done
i dont had a lathe or a milling machine, i have a benchdrill and a 3d printed, the way i do it is print a rectangle with a center hole of 0.25 mm less of diameter of the bar, and another hole in the top.then i pass the exact drill of the shaft, put it in the vise, becouse is rectanlge is going to be almost perfect squared, i printed several, but its highly recomended first make the deeper hole you can with the center bit
I've seen myself score a line on one end of the bar and along the length of it. Line up the score on the end with a 90° tool (vee-block, steel rule, parallel bar etc) and just drill as many holes along the length as you wish
I messed up 2 of my parts for my college part making a piston pin and I need them in around 2 classes so I hope that this helps me tomorrow I need 11 pistons total 😂
Genius!
Love it
So bottom line is it will be as accurate as the hole punch and how well you center the vice and drill press. But hey, depending on what you are doing, it's probably close enough for most applications and a good improvise. Good stuff for those who don't have access to a machine shop.
thanks I like it
Thanks
Finally boys!
Now I can drill in center center.
Nice one .
I'm no machinist but this looks like a neat workaround. I see down-votes and I comprehend the logic but there are indeed many ways to skin a cat.
I don't have a lathe or a mill. You probably don't need this trick if you have a good mill. To get my perfect hole, I use a square file and in a single stroke make a flat on the bar. Careful measurement and marking with a punch. Then center a V Block on your drill press in a vise and drill using a small carbide bit.
You can put the center drill in the mill chuck, you know.
Nice trick cheers
If you place a piece of fine emery cloth, or similar, along the movable jaw between it and the work piece and drill guide (abrasive side away from the jaw), it will absorb small height differences and grip both securely. This applies anytime you want to grip more than one piece securely in a vice if their heights, or jaw parallelness are not perfect.
Marks Myth thanks for that
thank you!!!!!!!!!!!
very good
Not to bust your bubble but there a about a dozen basic ways to cross drill round work through the axis. The quick lathe bushing idea is great but time consuming. I suggest learners of milling and drilling techniques look into the uses of the wiggled.
Fine !
Nice!
Smart people tend to use a center drill instead of risking to break stuff because their part wasn't properly secured.
