Re: Rotating the head of a Bridgeport clone

There are 2 other fasteners opposite 1 and 2. Loosen all 4 and it should turn. However, the top assembly is very heavy and can overload the worm drive once you get very off vertical. So use your hands to help support the top drive assembly as it comes around, don't let it just ride on the drive. Wit...

Re: Bits Spin in Hand Drills

I've got an old all metal 5/8" (chuck) B&D from the 60s. Even at that size, if it catches the bit, it's best just to let it go. It could easily break bones. Every time I've had to use it in cramped spaces, I always try to keep anything connected to me well out of the recoil line and prepare myself t...

Re: What is this toolholder?

Looks like it's a spring tool for an old lantern tool post. The tongue-n-groove below would help provide lateral stability, but still allow the tool to move down and away should it encounter problems.

Re: LED Shop Lighting

Exactly.

And in the future, I'll never cut off the "unnecessary" wire again, but rather tie them together outside the tombstone. Even if I have internally shunted LED tubes, who knows what I might try to install in the future, so better safe.

Re: LED Shop Lighting

I've been doing the same thing. Getting the 4' T8 replacements, removing ballasts, and moving on with life. But one word of caution. I bought a new brand to try, on sale, what can I say, I'm a sucker. Anyway, there was no marking to distinguish one pin from the other. The line drawing that poses as ...

Re: Bearing Fits?

I've use the green stuff, 620 and 640. Good stuff when you must, but I prefer a mechanical fit. As I understand it, that is also important for proper internal loading for the bearing to last. In fact, one of the things that pushed me into learning and doing my own machine work was a the last job I h...

Re: Bearing Fits?

Speaking of measuring the bearing to start with, that seems a necessity for most home shops that don't have a calibration schedule. How else do you know if the mic you are measuring with is going to help you produce a hole within a few tenths? That's assuming you are measuring with t-gages. Two week...

You should sign up on and check the Rockwell Lathe Yahoo group . You can find manuals in the files there, and lots of information (like belt suggestions and numbers) in the archives. There are also a bunch of helpful people with lathes just like yours. This forum is great for general machining quest...
