Dial Bore Gauge
 

I've had a Fowler 0.0001" 2" to 6" "Extender" digital bore gauge for
several years, but really have not gotten much use from it as I only
have a half dozen or so ring standards to set it. I really need a
setting gauge or a lot more gauge rings, which would take up a lot of
space. Fowler has a setter jig, but it's about $2500. I see used
Sunnen gauge setters for sale on ebay from time to time in the $500
range, but I'm not sure they will work with the Fowler....anyone know
if this will work?

Don't know if they will work or not. Just use an OD mic to set. Or a set
of gage blocks, if you have the type that will connect with a screw and has
end pieces.

Harbor freight has a mike holder for about 10 bucks that will hold the mike
for you as you set up the dial bore gauge.

If it's the one I've seen in the ads, it's only got two diametrical
contact points, not three, so either a set of gage blocks with ends or
even a good mike could be used for setup. Rings are really only
needed if you've got three contact points. I've got a few bore gauges
like that. Hope you've got a temp-controlled lab if you're expecting
good tenths measurements.

Depending on the tol. you are working to, bearing races make a good
gauge to set your bore gauge. You have to check the spec for the bearing.

Don't know if they will work or not. Just use an OD mic to set. Or a set
of gage blocks, if you have the type that will connect with a screw and has
end pieces.

Or a set of compression frames and the long end pieces for the
standard rectangular gauge blocks. I've got such a set (by DoAll) but I
can't remember (if I ever knew) what it is called. A collection of
telescoping frames of various lengths, and two extra long blocks (1" long
between measuring surfaces, but something like 2-1/2" wide with a hole
near one end for the pins which hold the end pieces into the frames to
be clamped onto the stack of gauge blocks.

Enjoy,
DoN.

I guess I need to invest in a set of gauge blocks or make some sort of
jig to hold the bore gauge square with some of my mikes.

Just use your vise, wrap a shop rag around the shaft and clamp LIGHTLY so
you can set it with a mic. That will hold the bore gage steady to find the
smallest reading.

One of the cheap Chinese gauge block sets should suffice. They
are within +/- 0.000050", so with worst case, you could get a
ten-thousandth ("tenth") error for two blocks stacked, and in all
probability, the errors would mostly cancel. The surface finish on the
cheap Chinese block sets is poor enough so they don't "wring" well, but
it should work well enough for your purposes.

Out of curiosity -- what is the resolution on the dial gauge?
If it is to tenths, you are probably within reason, if it is to
thousandths, you are unlikely to make a stack of blocks tall enough to
reach the resolution of the dial gauge.

Good luck,
DoN.
