Re: Long Parallels

I'd like to have a couple sets of 8 inch parallels.  Sixes work, but
sometimes I can't see when one end is over the gap in the vise bed.
I've got lots of 6 inchers.  Think, thin, and a couple sets of regulars.
I don't need a bunch of sizes, so I guess make them is not out of the
question.  I'm not particularly skilled with the surface grinder, but I
have one.

If you have a (granite?) surface plate to check them on you can detect and correct grinding errors.
This is the owners manual for mine:

I've also run a Brown & Sharpe, which was generally similar. The Toolmaker sacrifices some precision and surface finish for versatility, usually a grinder head is more rigid. I found the swivel table for it, for sharpening taps etc between dead centers. That's why the head can swivel. The British Quorn cutter grinder has a nearly identical head arrangement and I've collected accessories to duplicate some of its functions.
