Hey Tom, thanks a lot for turning me on to this channel! Ever since you gave Stefan a shout-out, I've subscribed and been catching up on his videos. Cheers, Michael
This series is both enjoyable to watch and interresting, indeed. Am looking forward to the next part of this presentation. Always is nice to see the little tricks to get a better set up and more accurate measurements. Thanks for sharing.
I really appreciate how you are very detailed in explaining what you are doing and the reasons why. Very informative! As a hobby machinist I learn a lot from watching your videos.
Great project Stefan. Once again, the shaper does excellent work and some nice precision set-ups.Most enjoyable. I made myself one of the jigs for band saw short pieces (using Chuck's idea).
Great video. I use sine plates with magnet chuck for puting reliefs on shear blades but I use the sine bar if I need to sharpen cut off blades that have a taper to them. I work with progressive dies that stamp metal wood connectors. I’ve made v blocks, 123 blocks and angle blocks but I may have a go at making my own sine bar. This video helps me.
I've watched it before, and TOT's description of a sine bar, and for some reason, watching it be built... well, now it all makes sense. Why the 45, and such. Plus, honestly, I miss the shaper, and was feeling a bit nostalgic.
Nice job. I've been thinking about making a small sine bar myself. My large sine bar is good for setup and creating layout lines on a surface plate,but is to big to use easily in my vice. can't wait for part 2.
As always, a pleasure to watch you work and listen to your philosophy of machining. As someone else hinted, I too might have been tempted to make one of them twice as wide, there are occasions when you could use extra width. c
I am amazed by the finish with the 6 flute mill, i'll need to try one. . Pity i am busy with other stuff now, i got to get my shaper back in action, miss that machine. I got a small logan 7 inch.
Recently I found I had need for a small sine bar, and so of course here I am watching this video again. :) It occurs to me that another reason for the odd shape of the sine bar is ease of precision in manufacturing - the shape is such that the distance between center of the gauge rounds can always be adjusted by machining small amounts away; increased by machining away on the "L-shaped" end and decreased by removing material at the other end. So you can very carefully achieve very tight tolerance for the length of the hypotenuse
The only thing I missed is that you did not show the finish cutting of the ramp on the shaper. I suppose it is the same as the rough cut, only with smaller feeds in vertical/horizontal, nicht wahr? What a great tool Herr (or Herren) Gack built.
+Bick1027 DE Ha, I decided to make my own rollers from drill rod, drill them and harden/grind them. Be ready some for toolpost grinder action in one of the next videos :)
Hi Stefan: Another reason not to cut the notches in from opposite sides of the bar, is if you do it that way, you only get one shot at the correct spacing. Once you go below 50mm, you can only make the spacing smaller. With both notches cut from the same direction, as you did it, you can make the spacing larger or smaller by choosing which face to remove material from.
Wow that's talent right there, thats why Germany is still number one, i might have missed the part about the material you are working with what type of steel are you using?
I love your videos Stefan! I do not really understand the benefit of using a shaper instead of a milling machine. To get the same height on both sides of the sine bar you can also mill it, don't you?
It took some research to find the equivalent bit the metal you are using 12312 is not available in the US, here that is equivalent to 4140 Tool Steel. Not an identical replacement but the closest readily available here.
Always a pleasure to see your videos, and to learn from them. Your running commentary is most useful. What is the standard used for the designation 123-12 tool steel you mention? Is there an equivalent designation? I've been trying to find a source in Denmark from where we usually order materials (here in Greenland).
+Jim Milne Try looking into a prehardened 4140. In the US it goes by the 4142 designation. Not sure it is the same stuff he is using, but it has the same properties he describes. I use it occasionally and like it.
"Get your slice of Sine Bar...Get your hot and fresh Sine Bar slices here!", LOL! Just like buying a Bratwurst at when you're at the Oktoberfest fairplex :) Thanks for another great episode, I always really enjoy your videos, sie sind meine Liebling aller...Aloha, Chuck
+Knolltop Farms Haha, yeah, but there is a problem: You buy only a whole Bratwurst. Slicing up a Wurst is a cardinal sin. Preferable are two or three Nürnberger Bratwurst in a Semmel. Thanks for dropping by, I always enjoy your comments :)
+Stefan Gotteswinter That's good to know! I'd never want to make a cardinal sin at an important cultural event like Oktoberfest. I have attended it only once, back in 1996 and I just loved it, I loved all of Bavaria! In Munchen, the people were so friendly and welcoming at the long tables under the big Hofbrauhuas tent...it's kind of amazing I can still remember it! What was ever more strange was when everyone started singing, I seemed to already know the words to some songs(?), so I must be more German than just the 1/4th I get from my father, LOL! Thanks for the advice and the reply :)
I got to say I really was learning from you and I still learned alot which I have to thank you for :), but as soon as you went to the shaper I tried to tell you please do it in another way so that we can follow too, by we I mean people who dont have a shaper, but some how you didn't listen !!? Oh well, I do hope that you show us how its done in another job without the Bl. shaper, Bl. just because I dont own one....:) Thank's man
Lovely work, I would like to be able to buy one of your Beautiful Sine bars ? It is always a great pleasure to watch your techniques. Thank you for showing us. kind regards. Malcolm
I have been looking forward to this series. Thankyou for your excellent humble and interesting video's. What brand was that mini "kant twist" style clamp? Thanks, Bert.
+Stefan Gotteswinter No, no, don't edit it. It sounds much better the way you did it. For some strange reason Mathematics and Physics end in "s" which says they are plural in English. If so then Physics don't care. In German it is easier because Physik is clearly singular. So much for grammar. I doesn't care, myself.
+cncua Thank you! The bandsaw increased my productivity by a huge amount - Before I had one I did all sawing with the hacksaw, kinda sucks to saw of a slice from a piece of 80mm steel round by hand...So I didnt start a lot of projects at all...and they show up used all the time for very little money, I paid less than 90Eur for mine (But it came in parts...)
you said you wouldn't use the sine bars for grinding since the distance wasn't exactly 50. but wouldn't it just be a case of putting in 50.005 into the calculator. then it would be equally as accurate as any sine bar
Right :) But there is still not the precision built into mine, I think. But to be realistic, it should be good enough for 99.0% of jobs I do in my shop - I used it recently to grind a few form tools and when I checked the angles under my toolmakers microscope, everything was fine :D
Shaper is inspiring, just impersonated one for Valentines Day, We, my Lady and I felt good about the shaper effect... llo By the way good sine bar tutorial... ;)
Vielen Dank für das informative Video. Noch gelungener wäre es, wenn manche Arbeitsschritte nicht übersprungen würden. Die Bearbeitung der Schräge hätte mich beispielsweise interessiert. Wenn noch deutsche Untertitel eingeblendet würden, wäre es vollkommen.
Dankeschön! Oft steht mir leider einfach die verfügbare Zeit im Weg - Zum einen beim Filmen in der Werkstatt, ich will ja irgendwann fertig werden, zum anderen beim VIdeoschnitt - Ich will die Videos ja nicht zuuuuu lang machen, da bleiben leider manchmal kleinigkeiten auf der Strecke.
schade eigentlich, das ein deutscher seine videos in englisch kommentiert, versteh nicht, was das soll, bin ich wohl zu alt zu, dafür gibt es von mir einen Daumen runter
Größere Zielgruppe - Würde ich nur deutschsprechende Zuschauer ansprechen, wäre der Arbeitsaufwand für ein Video völliger Irrsinn. Ich glaub ich pack genug deutschsprachige Inhalte in schriftlicher Form ins Internet, das ich da kein schlechtes Gewissen haben muss :)
8 years later, I finally made a version of this. Thank you for the processes although I used a vertical mill inplace of shaper.
enjoyed!
Looks great, next step is to attach a grinding spindle to your shaper head and let it auto grind!
Nicely done. A little sine bar army. Some day I'll show you my "Big" Bessey clamp. Lets just say Adam would be proud.
All the best,
Tom
Hey Tom, thanks a lot for turning me on to this channel! Ever since you gave Stefan a shout-out, I've subscribed and been catching up on his videos. Cheers, Michael
28:04 the 3rd part perfectly lines up with the sketch. So satisfying!
This series is both enjoyable to watch and interresting, indeed. Am looking forward to the next part of this presentation. Always is nice to see the little tricks to get a better set up and more accurate measurements. Thanks for sharing.
I really appreciate how you are very detailed in explaining what you are doing and the reasons why. Very informative! As a hobby machinist I learn a lot from watching your videos.
Thanks Stefan, nice to see some shaper work for a change. Sweet little sine bars! I enjoyed this very much.
Great project Stefan. Once again, the shaper does excellent work and some nice precision set-ups.Most enjoyable.
I made myself one of the jigs for band saw short pieces (using Chuck's idea).
Making things is good but making your own tools & jigs I find really satisfying.
Great video. I use sine plates with magnet chuck for puting reliefs on shear blades but I use the sine bar if I need to sharpen cut off blades that have a taper to them. I work with progressive dies that stamp metal wood connectors. I’ve made v blocks, 123 blocks and angle blocks but I may have a go at making my own sine bar. This video helps me.
You make this look easy. Lots of thought & practice go into each project. It really shows threw your work.
That loaf of sine-bar is the best thing since sliced bread
Thanks for sharing. Looking forward to part two!
Always enjoyable to watch you work, Stefan. I've been looking forward to seeing this video series!
Hope you are well,
Tom Z
+Tom Zelickman (Inspiration Metalworks) Thank you Tom, the second part is already shot and down for editing :)
I've watched it before, and TOT's description of a sine bar, and for some reason, watching it be built... well, now it all makes sense. Why the 45, and such. Plus, honestly, I miss the shaper, and was feeling a bit nostalgic.
Nice timing. I was getting close to taking sine bars off my to-do list and make a bar and a plate soon.
Great video. I enjoyed watching the shaper do its magic. Such a simple tool can do such precision work.
Nice job. I've been thinking about making a small sine bar myself. My large sine bar is good for setup and creating layout lines on a surface plate,but is to big to use easily in my vice. can't wait for part 2.
Great project Stefan!.....you make precision so neat, easy, and clean !
always enjoy watching your very well crafted uploads - much to learn and think about watching your videos - thanks
Pete
Nice project(s). That job just seems to be a natural for shaper work. Gonna have my buddy watch this one as he loves his shaper.
Colin

Great video. Very nice way to make a lot of sine bars. Do you really need 6 sine bars or is this just because you can? Thanks for the video.
Stefan, Wonderful technique and results. Look forward to how you tap and mount the hardened bushes or drill rod.
Bob
+Bick1027 DE Ha, I decided to make my own rollers from drill rod, drill them and harden/grind them. Be ready some for toolpost grinder action in one of the next videos :)
+Stefan Gotteswinter Looking forward to it!
Enjoyed/very interesting! Thanks for the channel mention, I know if you build one for your bandsaw it will be an improved version!
Someone should make a set of precision ground magnets for edge measuring.
Great, always a pleasure to watch you at work, thank you.

Bravo Stefan, great video! Shaper machine is excellent.

Cool build so far! Is there a reason why you made them all the same width, or is there not much point in making some narrower and some wider?
It took some research to find the equivalent bit the metal you are using 12312 is not available in the US, here that is equivalent to 4140 Tool Steel. Not an identical replacement but the closest readily available here.
Good video very interesting keep them coming.
Uncut, it’s a sine plate. Very useful too, with a few threaded holes in it.
As usual, 10/10 for engineering excellence, but why would you need 6 Sine bars?
Always a pleasure to see your videos, and to learn from them. Your running commentary is most useful. What is the standard used for the designation 123-12 tool steel you mention?

"Physics don't care about the price of a tool", Stefan Gotteswinter, Sep 27, 2015
+Brian Stanga Still the case ;)
I am working on a video series: Machine shop physics ;)
Kool, looking forward to it, is part 2 of sine bar up?
I try to edit it to the end of next week :)
I know that feeling. edit out eveything that is not a video..lol
+Stefan Gotteswinter No, no, don't edit it. It sounds much better the way you did it. For some strange reason Mathematics and Physics end in "s" which says they are plural in English.

Looking good brother
Cool project
Looking forward to get next video in serie
Thank you for sharing this
/me wish I'd have band saw
+cncua Thank you! The bandsaw increased my productivity by a huge amount - Before I had one I did all sawing with the hacksaw, kinda sucks to saw of a slice from a piece of 80mm steel round by hand...So I didnt start a lot of projects at all...and they show up used all the time for very little money, I paid less than 90Eur for mine (But it came in parts...)
+Stefan Gotteswinter looks like I should buy one for myself.
+Andrii Podanenko Every household needs a bandsaw! ;)
you said you wouldn't use the sine bars for grinding since the distance wasn't exactly 50. but wouldn't it just be a case of putting in 50.005 into the calculator. then it would be equally as accurate as any sine bar

In a more serious vein, perhaps you could use a sine bar to put some meaning into Trig class.
Superb as usual. Very interesting.
stefan very interesting video looking for P. 2 .
Could you have measured out to out then measured the lip and subtract it?
Excellent as always:)
Stefan, Have you ever tried feeding the shear tool in the opposite direction? Would that work?
Thanks for the video, CJ
+CJs Custom Yes, works pretty much the same, I cant tell the difference :)
thanks for sharing
Metric gage blocks... Huh, never seen one before.
Shaper is inspiring, just impersonated one for Valentines Day, We, my Lady and I felt good about the shaper effect... llo
By the way good sine bar tutorial... ;)
+pierre beaudry We had also a very shaperish-weekend ;)
lol, Shaper is universal...
+pierre beaudry She likes the shaper too ;)
+Stefan Gotteswinter wait a minute, i don't understand. in the shaper video you said you only had two clapper boxes. please explain this 3rd one.
This Old Tony
The one way ones are for the shop, the back and forth one stays home... Simple... lol
Can I use tool steel and mill a milling tool and then harden it?
Yes but you should research what tool steels are within you ability to harden in your shop.
The Steel seems to be:
1.2312
40CrMnMoS8-6
AISI: P20+S
Absolutely right :)
Normaly thats a moldmaking steel, but I like it for tooling as well.
Making Sine Bread !!
Can you tell me for what the thread on the spindle of your milling machine is?
+1AB09CC3 That thread is on the MT4/Mt2 sleeve that I have quite a lot in use - Its there to pull the sleeve out of the spindle with a big nut.
+Stefan Gotteswinter Got it. Like on some types of live centers for a lathe.
+Stefan Gotteswinter BTW: jacknut would be the right term.
