I get a lot of use in setting angles with what I call a level box? It's a small 3"x3" +/- plastic device that measures angles to less than a degree. Someone will no doubt post the proper name and source. It seems accurate enough for my work.

Wow - coming along great. I really like your fixturing approach. I am going to use some of these in making my own engine. Top work.

The screw machine is a beast - what vintage is that?

That screw machine is small ⅝ inch capacity, single spindle....vintage? this one is mid to late 1950's

Thank you sir......the fixture approach was the only logical way I saw to both hold the work, and always have/ be able to find/pick up a master reference.

I don't have a digital protractor......up until now, I have a much larger mill with a 6 inch vise and all I ever needed was my sine bar, however now that I have a smaller machine & vise, a tool like you own might have to be had for the shop

Ahhhh the uninitiated.....that is a (brown and sharpe double zero) screw machine

Just so that I understand, you work in a museum that makes parts for historic race cars?

So I got a little farther.....being how I couldn't use a 5 inch sine bar in a 4 inch vise, I had to go with plan B.....make a sine block.......I blued the work, leveled it to the vise jaws by eye.....cut it, placed it back on the sine bar, sweep it with an indicator, off .007 , that's with in a couple minutes of arc.....close enough for this, I'm just drilling steam passages View attachment 165554View attachment 165555

For small parts you could use a small vise upside down. Then after clamping the small vise goes into the bigger one.

I hope one can get the idea from my quick sketch. Ofcourse the angle is reversed 90° - x.


Greetings Timo

That's funny....uuhhh, no. For certain parts , a screw machine will run circles around a CNC......

Interesting idea, I'm gonna have to think about that

I just have some of these in mind. I guess they cannot cost more than 1 or 2 stellar bucks. Happy programming.
There seems to be never a video where a real part is made. I guess, because all we could see, is coolant mist or oil fumes.
