Thread: Who chucked the chuck???

Bad luck Eliza
I bet the lathe did not even say sorry

I used to hold the chuck but then one day. The drill jammed and made the chuck spin taking my hand with it Lucky I had not drunk to much rum and I was able to let go before to much damage was done
Oh th joys of turning

When drilling long pieces like tool handles. You use the tail stock to push the timber into the drill.

I've used live concave centres to do this for all sorts of odd shaped pieces like asymmetrically shaped pate and cheese knife handles. The live centre is just in case if the drill grabs you can let the piece go and it doesn't spin the piece up against the fixed tailstock and mark the piece.

Sorry Eliza I misunderstood you.

Yes you could do the same in the tailstock but generally I don't. I hold my hand ready to steady the chuck if it comes loose in the morse taper.

The knee bar stop on my lathe helps stop the lathe quickly if I need to.

Two points to consider when using a drill in the tailstock. (and in the headstock end).

1: slow speed.

2: withdraw the drill often to clear the shavings, the deeper you go the more often you need to do this.

Now a bit about headstock/tailstock alignment. Most people check to see if the two centre points meet and if they do they consider the lathe in alignment. This is only part of the alignment issue.

The two points should meet, but just as important, both the headstock spindle and the tailstock spindle should be parallel to the bed ways in 2 directions, horizontal and vertical. Most lathes meet the first part of this test because it's fairly easy to achive point to point contact. However the second part requires much higher standards of engineering and quality control.

Sorry but you just don't get this standard of engineering in a Chinese built lathe. that said you could be lucky.

This is just one of the reasons people pay the extra money for, and love their
Vicmarc lathes.

One way to check aligment is to chuck a piece of wood 300mm long (shark jaws recomended) and carefully try and drill a hole in this. If the aligment is out the deeper you drill, the more the bit will bind. If this is out there is no way to fix this. You are stuck with it. Well no this is not true, you could buy a Vicmarc.

Eliza I hope this not too complicated an explanation. but if you followed the 2 steps above and are still having problems this may be the reason.

Now none of this is a problem if you have the drill in the headstock and the wood stationary. The lathe now becomes a drill press.

Good luck and keep that faceshield on.

Thank you for clearing that up, it all makes sense now.

Is Jet Chinese?

Like almost anything built from iron nowaday, bits of it are Chinese made. (The bed, etc.)

But JET isn't a Chinese-owned company, if that's what you're asking.

update.

Perdy colours!

Half sister if Mortitia? (Is that how you spell it? You know the woman off Addam's family. )

The eye or the hair? It's only black because of the light. It use to be down to the top of my thighs and I'm growing it again.

I'm so glad April is over. Pnuemonia, the black eye, and yesterday, on the last day, found out that Gem needs an operation on her leg

You should not have shown everyone how pretty it is........ Now everyone will want one
