Picked up this 10” sine bar some time ago in a miscellaneous batch of tooling. I understand the basic functions of sine bars, but I don’t understand the clamp type addition on the end missing the roll.
The bar was made by Machine Products Corp. of Detroit. It appears they were makers of precision measuring equipment with a line of angle plates, v-blocks, etc.
It is drilled to allow another 1” roll to be screwed on the end missing one. Not sure why the roll installed is about 1/2” wider than the bar on one side.
Anyone seen a sine bar like this and can explain the construction?
Thanks,
Dick
