Setting An Angle On The Lathe Compound (easy way)

How to set an angle on the lathe compound slide using a milling tramming tool. This technique works up to about 8 degrees. It is limited by the range of the DTIs. The example in this video is to setup the lathe for cutting a #2 Morse Taper. Checkout the web site at the end of the video for free construction notes on making the tool.

Is the calculator you have on your computer a free download or software that you have purchased?

@zippy308 Machinery Calculator is a set of useful tools available from the web address at the end of the video

Nice piece of software but isnt it a bit lazy ? Just use SohCahToa and any Scientific Calculator !

@richieT737 that was not the question!

the software cost´s

Very nice Video!

It helped a lot. Thanks.

But I think there is a litte error in the calculation. The distance between the two dials should be 'A' and not 'C' because the dial pin is mounted perpendicular to its holder. The difference in the dials is then again 'B'.

Your alignment using 'C' is nearly accurate, because for small angles alpha the following is true:

B = C * sin(Alpha) = A * tan(Alpha)

This could explain your slight error in your final check.

Very well done! Thank you!

Its good to see people using new and different methods to achieve a result. for me i use a digital angle finder to set my compound accurately when i need it. Without sounding anal, you refer to your indicators as DTI (dial test indicator), this isnt really correct, those are plunger type so they are just dial indicators, dial test indicators use a lever action. Good video though.
