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!

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!

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.

Looks great, next step is to attach a grinding spindle to your shaper head and let it auto grind!

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.

Great project Stefan!.....you make precision so neat, easy, and clean !

Making things is good but making your own tools & jigs I find really satisfying.

You make this look easy. Lots of thought & practice go into each project. It really shows threw your work.

Great video. I enjoyed watching the shaper do its magic. Such a simple tool can do such precision work.

always enjoy watching your very well crafted uploads - much to learn and think about watching your videos - thanks Pete

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).

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

Thanks for sharing. Looking forward to part two!

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

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 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.

Excellent video as always! Thank you for sharing.

Enjoyed your videos. Waiting for part 2. Thanks

Great, always a pleasure to watch you at work, thank you.

Nice timing. I was getting close to taking sine bars off my to-do list and make a bar and a plate soon.

Bravo Stefan, great video! Shaper machine is excellent.

Always enjoyable to watch you work, Stefan. I've been looking forward to seeing this video series! Hope you are well, Tom Z

That loaf of sine-bar is the best thing since sliced bread

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.

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.

Enjoyed/very interesting! Thanks for the channel mention, I know if you build one for your bandsaw it will be an improved version!

Love it. Thanks for sharing.

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

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.

Excellent as always:)

Good video very interesting keep them coming.

Superb as usual. Very interesting.

Stefan, Wonderful technique and results. Look forward to how you tap and mount the hardened bushes or drill rod. Bob

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.

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.

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

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.

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?

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?

Looking good brother

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?

Someone should make a set of precision ground magnets for edge measuring.

Uncut, it’s a sine plate. Very useful too, with a few threaded holes in it.

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

stefan very interesting video looking for P. 2 .

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.

Is that a mauser stamp on your micrometer? If so, awesome!

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? Is there an equivalent designation? I've been trying to find a source in Denmark from where we usually order materials (here in Greenland).

+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 :)

In a more serious vein, perhaps you could use a sine bar to put some meaning into Trig class.

Could you have measured out to out then measured the lip and subtract it?

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

@StefanGotteswinter

7 жыл бұрын

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

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.
