Somehow I've never seen one of these before, looks like a nifty piece of kit.

It has the slight inconvenience of mounting a tie bar, but as far as I can tell, no matter how skewed your mounting is, it can't fail to put you on the spindle rotation axis.
I'd buy one now if only it wasn't so blooming tall :whistling:
Hang on a bit, a shorter one coming to a store near to me anytime now, might even be cheaper as well. :tup:
Robin,
My colonial .02 worth. I bought one several years ago and it worked great for its design purpose.
HOWEVER, I have now gotten into using a probe to do all my edge and center finding work and haven't used it in quite some time.
I modified one of these (hope the picture comes through):

by removing the battery and led and putting a probe wire thorough one of the holes. Then I use an appropriate probe command to find either an edge, top, or center of a hole
PS: A lot cheaper also!

One of these looks like a goer for a probe mod? but i do like the idea of the gauge one for centering

I just bought a probe but does that little ruby ball really sit on the axis of rotation? As soon as the weather warms up so I can get back in my workshop I shall find out :naughty:

The dial does away with all concentricity issues. But I have a round column mill so the long body on the one I found would result in spindle overhang.Quote:

LOL! just remember to use plenty of lube to avoid chaffing then
A wiggler set! Just search rdg or chronos for wigglers, found a set for £5.40, just add a dial gauge, or one of those mag mount digitals (an essential engineering tool with a zillion uses). They are also easy to make, any bit of bar, end doesn't have to be ground special as long as it fits.

I was wondering about making a coax indicator. But a dial gauge mount
that can be used while tools are in place seemed a useful bit of kit to be going on with.
I marked the shape of the spindle clamp out on bit of ali a few years ago, but I have other plans
for the bit of metal so kept putting this off, Finally thought it would save a lot of messing about
so I cobbled one together with bit's of scrap.

I like that, it puts the measure right where you want it and no tool change before you cut.
I might pinch some of that :smile:
Is that a set of girder forks i see?
Yes.Quote:
