Another "Extraordinaire DIY" to Steve Maskery! For, mathematics (especially Geometry and Trigonometry), I rely loved it. Comparing History and Geography, etc; was to me "To hell with those"! And "I will stick with me math. Amen!" But the truth is: I made a horrible mistake. That has bugged me for 70+ yrs of my 90 yrs, on this planet. But I still love math to the "nth" degrees. And to see you take a very difficult "fact absolute"; when it comes to angles (other than 90, 45, 30 and 60 degrees); and make it so simple; proves that you are truly a "Cut Above", kind Sir. Thank you Steve, for sharing your innate talents, with us. Love it! 😍 🤠
I was the guy writing on the desk. 40 years later some trig has finally soaked through my skull. I’m gonna make my sine bar to up my woodworking game a bit. Great explanation and examples of use. With a bit of tweaking the miter gauge bar fit to slots and using the sine bar, even a basic tool should be very accurate. Cheers!
@agn855 and yet metric is a much closer and way more accurate way to measure, which throws this sine bar angle accuratecy out the window. Particularly after half-pie guessing the near enough centers between the two brass inserts. Waste of time to make and use, especially when you can download a super accurate angle app on ya phone these days
That's a tool that machinists used for a very long time but that woodworkers have not made good use of. That said, it would make sense to make spacers for commonly used angles such as 30 and 45 degrees and for others that are often used, but for one-offs one could just use the vernier calipers, particularly if the sine bar was integrated as part of a sled..
Good video, good tool. BUT, if your caliper is digital or dial it isn't vernier. I don't use digital or dial calipers, I use vernier calipers. Verniers are more robust, less susceptible to incorrect readings. They are a bit fiddly if you're not used to them, but they are "trustworthy" every time. If they close at zero then they are calibrated correctly.
Good Morning Steve! Brilliant as always. Since I have no degree in engineering (biologist), I wasn't aware of this little gadget, but I will make one as soon as I have built another jig, which would also be helpful for you, to keep at least two hands when cutting this sine-bar parallel on the table saw: just by coincidence, a German woodworking channel yesterday uploaded a video on a jig, that helps cutting thin stripes of wood acurately. I think this might also help to keep the fingers much further away from the blade when cutting the back side of the sine bar parallel to the anvils. Here is a link to that video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eVpNTJnkduY.html Jonas is a really cool guy (if you don't judge a book just by the cover 😉). Thanks again for the excellent video
Hi Andreas, glad you liked the video. The problem when trimming the edgeis that, because there are only two points in contact with the fence, it is VERY easy for the workpiece to pivot. A standard feather board does not holp, because it applies pressure in front of the blade, rather than on the blade. It's a really tricky cut. But my blade guard completely covers the blade, riding on the workpiece itself. Even so, I have to concentrate. Thanks for the heads up on the video. I wish I spoke German, he sounds fun. Who has houseplants in his workshop?! And here is my very similar solution to the same problem. The quality is dire (it's from a previous life) and you can skip the first 45s (what was I thinking?!) but you'll get the picture. I still have that jig, I think perhaps I need to remake the film. Enjoy (if you can). ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lp4ZR5WsL9w.html
Funny, he uses a phone to calculate the angle block length, when he could easily download one of the many very acurate angle apps to prove angles... without mucking about the hassle of having to hand planning tiny blocks to length or to use any sine bar laying about. Stop yibber yapping to ya phone and get up with the times - old school techniques left earth a couple decades ago.
First thing i noticed watching your video, is how much you sound like Michael Caine the actor. I wasn't 20 seconds into your video and your voice was the first thing that hit me.
