For the uninformed in the crowd (@DavidR8 pointing at himself) what is this tool used for?

bench centers are used for holding and indicating cylindrical work (usually)
it can also be used for indication of polygons

Thanks @Ulma Doctor, that makes sense.

Hey Mike,

Interesting to see delrin in the shaper......in my mind, the elasticity of the material might come into play.....moreso than on the mill or lathe.
Just curious: Did you notice the entire block changing shape during a cut?
I suppose it would depend on how much material length is out of the chuck jaws.

it was a complete S#it show
the whole slug moved back and forth.
the delrin was just a test to see what i could get away with.
truth be told, i figured if the delrin went flying, i wouldn't put bronze in the rotary table

delrin machines beautifully on a shaper, in a vise

here is an updated picture
i'll take a few more finish cuts on the left side as oriented, to reduce the width a bit

Hold on, I thought you went down the 3D-Printer rabbit hole. What this shop fab about?
- Looks good.

Thanks @middle.road!!!
don't think for a second i wouldn't try my hand at printing a set
