Angle Plates 30-60-90Degrees

I have some thin angle plates but they are sometimes a little wibbly wobbly if you know what I mean, So I decided to make some quiet a bit thicker for a little more stability.

They were made from 0-1 Tool Steel, they measure appr..750" X 2.500" X 4.250" hardened and matched ground to within .00015", that's as accurate as my cylinder square is.

I ground the 30Deg angle on a 5" sine bar which I made, ( It's posted on Homemade Tools.net as well )
I made the 2.5000" gauge block to set the sine bar from O-1 Tool Steel. ( hardened and very very carefully ground )

I'm going to eventually make another pair of plates that's 45-45-90 Degrees ( Same Steel )

Below are some photos

Thanks for looking
And Happy Machining
