I have been using a Blake for many, many years and love it. But I never
cared about the graduations, I just center it as close as I possible can and
go for it.

I loved mine, I could center holes, pins, etc, in short minutes -
faster than I could any other method, even including the 'set up'
time.

Mine's required service for some time (no round tuit available).
Imagine my delight in discovering that Blake will disassemble,
clean, reassemble and certify it for only $40!
