How to Use a Sine Bar to Indicate a Vise to an Angle

[@bobjohnson6743]

When I was a Machinist back in the 1970's instead of magnets I would use a DIE spring from the movable jaw and the sine bar to make sure the sine would not move.

Thanks! If I was a young man again, I would jump at the chance of going to your school.

Thank you for teaching us

Great info. Thank you

[@owievisie]

This is one of those things that I like about being a machinist

I realize I'm kinda randomly asking but do anyone know a good website to watch newly released series online ?

Thank you nice presentation 👍

I do gauge blocks from the big end. I start with the largest block that is smaller than the finished stack. Then the next biggest block that fits in the remaining gap and so on until I have the right size. Starting at the small end makes no sense to me.

I would definitely remove the end stop from the sine bar, it's just waiting for the indicator stylus to hit it.

The sine of an angle does not have units of inches. Sin 10 is 0.173648 since sine of the angle is the ratio of the opposite side divided by the hypotenuse of the triangle inch/inch is dimensionless ie you do not have imperial or metric sines, just a thought.

You don't need any stupid sine bar to do that.

Really? How would you get within one .001" over a five inch distance, and be sure you were within that spec? Suppose it needed to be within .0005"? I'm not saying you can't do it. But at some level of accuracy you need more precise methods, I suggest. And at that point a method likes this seems to be useful. At least it is illustrating how to use the precision allowed by a sine bar to transfer that accuracy to a machining setup. I found it useful, anyway!

@@SeattlePioneer you fixture it so that the table rotates to 10 degrees and mill.

So start teaching online classes and share your wisdom.
