Hello:
... you will be turning the test bar between centers ...
I'm sorry if I did not explain myself correctly.
I won't be turning a bar.
I already did that to see how close I could get to a reasonably good alignment without a proper test bar.
Now I will be purchasing an already
ground and hardened 20mm steel bar and a machinist with a precision lathe will make the centers for me.
The result will be a quality test bar (G6 tolerance and 62HRC surface hardness) for my U3 which will allow me to rapidly align it everytime I need to unmount it for cleaning, maintenance, etc. without the hassle of having to turn a piece of stock.
Much like this one ...
... but in a length to fit the U3's 180mm between centers and at a fraction of what the one in the photo goes for.
No box needed as a ?1.75" PVC pipe with end caps and a neoprene lining on the inside will do just fine.?
Thanks for your input.
Best,
JHM
