I bought a set of B&S angle blocks with the stop on them. I have found them to be super handy. The angle blocks without the stopper are handy as well. I cannot remember the last time I used my sine bar. The work I do does not rusty it's use. Cheers
When I went to trade school, our math classes were structured so we would learn the math applicable to working in a machine shop. Im not sure if all schools do that, but it definitely helped me wrap my head around it.
Good evening Phil. Always a great pleasure to hear your thoughts and wisdom. Thank you for sharing. A question for you if I may. Could you please tell me how you would go about qualifying a sine bar/plate for centre to centre accuracy. Without the use of a master angle gauge. Welcoming your thoughts, all the very best to you and your family in 2025. Cheers and very best regards. Ron.
Don't worry, everyone puts the sine bar under their parts. Put the bottom roller against a vise stop and use the stop on the sine bar to locate the part in the X axis Then you can accurately repeat the position for multiple parts. I hold the sine bar against the fixed jaw with a spring or 2. If you try to use it on the top you must make sure it is aligned with the X axis and held there while you indicate the top.
@@TheToolandDieGuy Ok, I've watched it four times now, and I think I caught it... I think. If you're referring to the part from 4:00 to 4:30 I misunderstood it as the larger bar being for larger parts. I had a Metal Shop Teacher use a 10" bar to get a 0.5° accuracy on a 1" bit of metal by placing a 3ft flat bar on the small piece and the sin bar on that. Anyway. Great video as usual, but I guess that part wasn't clear to me. Likely because I must be sleepier than I thought. It is late and I'm watching this in bed since I'm the kind of Nerd that reads tech manuals, textbooks, and engineering and laboratory white papers for fun. Looks like I'll be dreaming about lathes and mills tonight, judging by what I've been watching the last few hours.

I really wish they would teach math , in School, in an applied fashion like this. Great job.

How accurate do you think those digital angle finders are and have you ever tested one
using a DTI on a surface plate with a sine bar?
Thanks for sharing 👍
Okay, you don't put the sine bar under your part. How do you use the sine bar??

@tates11 thanks
You forgot to mention another reason for the longer sin bar: the longer the bar, the more precise you can get the angle.
I covered that. Watch it again.
