Re: Digital Electronic Vernier Caliper
??? CFL's are great for makin noise , but so are some of the
import LED's too . I've seen a couple folks that have gotten? a
single AA? or maybe it was a AAA battery holder & solder the
leads to the battery contacts on the caliper ( digital ) &
then double stick tape or some other method of mounting the
battery holder to the caliper . Makes it real easy to remove the
battery . a lot of the cheapo's don't turn off when the power
switch is used , they just go to sleep . I bought my batteries for
these calipers at the Dollar tree for years & years 4 for a
buck . I think their up to the 5 buck mark? for 4 these days .

Hi WAM
Maybe !!!!"
I just changed my roof lamp from a low Watt CFL to "150 W" LED.
I will test to morrow.
Maybe I still can get an old Edison lamp? It will also keep my

Re: Digital Electronic Vernier Caliper
I've found that the DROs on my mill become sensitive to electromagnetic interference when their batteries start to go flat.? So yeah, try replacing the batteries in? your affected digital calipers.

Re: Digital Electronic Vernier Caliper
We were doing FCC testing on one of our Large computers @ 1984-85 .
One machine sailed right through & the 2nd after lunch started having
problems , we put foil everywhere we could aloft with steel braid? with
the rubber on the inside . Finally my boss asks me if the lights were on
during the morning test & I said I was pretty sure they were not on . He
goes over to the panel & hits every breaker that said lites & boom
things got much better . He told the guy " I'm not paying you $ 125.00 a
hr to find out you have bad ballast's . Those were the old 8' tubes with
the 2 small pins on each side? HO's they were called back then .

Re: Three Jaw Chuck / Spindle Bore Opening
Just build yourself a momma boring bar, a few light?cuts is all it takes. That will even help with recentering the bore. Still much faster and cheaper than waiting for a reamer and paying for shipping/deposit.
It was rather expensive for a tool you'd only use once in your life. Maybe setting up such a program again would be a good idea, with a hefty deposit to borrow the tool.

Re: Three Jaw Chuck / Spindle Bore Opening
It had a shortened shank & (IIRC) a #2 Morse taper end to let it fit snugly in the TS. Cleaning it & removing the excess shipping labels from the package took longer than the actual reaming. Previous users had slapped so many new labels on top of the old ones that it was unwieldy.
