Digital Electronic Vernier Caliper
I can not work without many "Digital Electronic Vernier Caliper" in my workshop.
However, they are always hiding them self when I am doing my job.
Lately I have discovered that they are missing the numbers on the display.
Both old and new ones.
Suddenly the numbers are being negative or shutting down.
I am blaming a Comunicacion tower not far?from the building.
Someone's that has a good advice for me?
Best from

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.

If you want to have a peek at the article before you invest in the magazine, your public library just _might_ have access to this magazine. Our public library here in Winnipeg enables cardholders to access Model Engineers Workshop through the "Overdrive" digital media application.?

Catching up on my electronic subscriptions the Oct 2024 issue of Model Engineers Workshop has a pretty interesting diy indexer for the mini lathe . This is a English Magazine , but it's available at most book stores that have a fair sized magazine dept . I subscribe to this & read online . It seems they have more projects in one month than the other 2 mags do in half a year . They should be having their black Friday subscription drive going on about now .

Re: Three Jaw Chuck / Spindle Bore Opening
I agree you put a bigger hole.?
I have not had to bigger hole but I look at the scroll bearing size the hole needs to smaller that bearing.?
?
I typically buy chuck with hole size? I want.

Re: Three Jaw Chuck / Spindle Bore Opening
John, I see no reason why the three jaw chuck bore could not be bored out to a larger size, in fact I would want to increase the bore size to as accommodate larger material if space allows.
