I don't know - but my face caught it.

The drill bit seems to have broken - I wonder where it is?

How did that happen? :no:
Did the taper come loss while you were winding the drill out? :doh:
Good job you've still got both eyes.:C

It got stuck in the wood, I turned it off, but pulled it out before it stopped spinning and the whole chuck just came out of the tail stock and got me in the face on it's way out. I think the drill bit must have broken when it hit the ground. I don't know, can't find it. No doubt it will turn up.

We are buying a mask next pay...

a chainsaw mesh sheild is the best way to go. the plastic ones fog up and dotn do mutch if hit by sompthing heavy.

how mutch chuck could a woodlathe chuck if a woodlathe could chuck chucks.

The rest of the drill might be in the wood. :think:

Close call though. Look after yourself. I hope you have steel capped boots on your list too. :C:C (FWIW I like the clear face shields cos it means the dust has further to go to get to my nose.:rolleyes: )

next time you are up my way ,call in and i will give you a faceshield before you do some serious damage to that lovely face of yours,that was close to your eye Eliza , may have been a warning......bob

You can stop the clear ones fogging up by just putting 2 drops of undiluted liquid diswashing detergent on the inside of the plastic and rubbing it all in with a tissue or soft rag

Bob you are too sweet :)

Won't be up your way again until Mothers day though, and Zoe has offered to buy me one from Carba Tec which is only a couple of blocks away.

I so appreciate the offer though!

Ya, swollen and black or not, I have pen blanks to glue in, then turn!

But, I'll glue tomorrow, take the rest of the day off, see how I feel the next day.

Surely I can't get into too much trouble turning pen blanks on a mandrell?

What could go wrong?

(geee, I wish I hadn't asked that!)

I also fell down the stairs today, fortunately I waited until I got to the bottom two, and didn't start at the top of the 15! That should have told me something...

Sounds like it was not drilling true, the off centre mass of the chuck braking the drill. Lucky not more damage was done. You definately should be wearing a shield.

I find that the drill does the first few ok, but as it heats up, and depending on the wood, if I don't clear it often the sawdust in the grooves of the drill bit swell, and I get a stuck drill.

Yesterday was my first day back at the lathe for more then a few minutes at a time, I was rushing and nothing was going right. I stuffed up two bottle stoppers in the morning, made two pens ok, then decided to cut and drill lots of pen blanks. I did about 8 or 9 polaris, about 10 seirra, and about 10 keyrings - and then it happened.

I was tired by this time, and rushing. Two things I shouldn't have been!

Let this be a warning to you all!

And, here is a picture of me at 6am this morning. How brave am I, putting up a picture just out of bed? lol

I'm going to tell everyone that Zoe did it. Well, I can't blame my poor lathe, can I? They might try to stop me turning!

Owwwwwww:C, You were certainly lucky (I know it doesn't seem like it now!) that it missed your eye. It would be well worthwhile to get a mask of some description. Just thinking about it my face hurts. (Then again there have been a few people that have told me it hurts just to look at my face:doh::D) Take care!

You are a fortunate Eliza, you are! Possible sequence of events?: Drill bit sticks, spins loose in the morse taper; you pull the tailstock back, dislodging the taper completely; the weight of the chuck, combined with the down-spinning lathe, swings the chuck to the side, breaking the bit, the chuck continues it's path to the floor, after hitting the nice lady just below the eye. Sound a mite close?
Face shield would deflect the chuck enough to keep from penetrating an eye, maybe... but the headband would make some nice marks around the forehead. :D
Careful, Mrs Leahy, you contribute too much to this forum, to be missing for long.

ElizaLeahy
27th April 2009, 10:43 AM
OGYT - that seems to be what happened, except the drill bit is not in the wood and I don't know where it is.

I went to Carba Tec this morning and bought a face mask. I kept my sunglasses on, told them the story, pulled off the glasses as I said "and then it came off and hit me in the face".

the look on their faces was precious! So many dropped jaws!

...well Eliza, now you see what can happen in a split second when using a lathe:C

All of the advice on having face protection is absolutely right on.

So glad that it wasn't any worse!

Eliza,

When you mount your drill chuck wipe off the Morse taper and put a bit of cloth on a stick and wipe out the socket on the inside of the tailstock spindle. When you mount the chuck push it in hard and twist. If everything is clean it will grab. The slightest bit of dirt or nicks on the taper or socket will not let it seat tightly and will make the drill run crooked.

Some chucks are screwed onto the Morse Taper adapter, and some have a taper on the chuck end. If chuck or adapter is marked JT33 or JT(other number)there is a taper on the other end. That taper could come apart also.

You have learned the below from painful experience, but I might add something new.

When you are drilling go in about 1 - 2 cm and then back out and clean off chips, repeat until you are as deep as you want. Letting the drill get hot makes everything sticky, dulls the drill which causes more heat, and things keep getting worse.

If you haven't done so, it is time to learn how to sharpen twist drills. A sharp drill cuts cleaner and does not get hot.

If things start going badly, hit the stop and back away until everything stops moving. If you can't hit the stop without crossing something flailing about, get out of the way and pull the plug. Or just get out of the way, the machine will come to some sort of conclusion without you having to go to the hospital.

I hope that you are using some sort of dust protection, at least a big hankerchief or cloth dinner napkin over your nose and mouth. I find that enough for me, but when I don't bother to use it the next morning I wake up with stuffed up head and cough all day.

Also if you are not feeling well, tired, or upset enough that you don't pay attention to what is in front of you, best not to use machinery.

Take care of yourself, I miss your posts when you are absent.

Thanks for the advice Paul, I'll do that, when next I go near the lathe. I'm not talking to it at the moment.

I was going to say get the face shield from Carolls - theirs is better IMHO
but too late

Also a drill press makes for easier and quicker drill extraction and thus quicker more frequent drill cleaning

Yow! Sorry to hear, Elizah. I haven't done the same myself, but I've come close... it's always the little things that getcha. :C

Still, one good thing has come from it: I bet it won't ever catch you in quite that way again. :D

Yep. Me too. Especially when drilling out with forstner or spade bits. It's one of the more awkward parts of turning.

I went to the trouble of having the small end of a MT tapped out to take a threaded rod, so I could slip it through the head/tailstock and use a washer & wingnut to lock it in position.

Works fantastically on the headstock... but on the tailstock? Well... it doesn't "telescope" too well when you have it clamped in position, does it? :doh::B

Ouch, Eliza...!:C

I hope that you touched some wood when you ask that question above:o!
You have no idea (well, you do...!) how easy is get hurt from the most unthinkable things.

I would have used the "shock" you created at Carba-Tec, and ask for a considerable discount...! did you? did they offer it?

I never liked to used that system for "normal" drilling, as I had a few "hairy" moments myself with it. I don't know where you can by a good second hand drill press, as I've been looking for one for some time, until yesterday when I received a email from Timbercom with their catalogue specials.
I have been looking for new stuff also and I saw those Timbercom ones on their web site but their were a little overpriced for what I wanted. Yesterday when I received the specials email, I notice that one particular model in their range was on special with some bonus clamps. Making a quick calculation, I added up the normal price + the 2x clamps part of the deal and come up with a total of $470.80(drill press)+$71.80 (2xclamps)= $542.60. The advertised price is $249 inc. GST, so a discount of $293.60 for those items. Even it the item was in Adelaide, it would cost me $40 either in freight or fuel to go and get it, this one is going to cost me $53 freight and is going to be delivered to my door. Now, adding the cost of freight on top of the advertised price, it comes to a total of $302, which is still $240.60 off the normal prices if you pick-up from their store.

I made the purchase based on the price savings and the fact that I have a very good use for those clamps, if the press has the ideal up/down travel in the head, without moving the base, I don't know as I can't find that information anywhere. I don't know if the chuck is fixed or taped, nor I know if the chuck is 13mm or 16mm.
Now, if I can drill my pen blanks in one go with it, that would be excellent, if not is a bit of a pain but the savings will overcome the inconvenience, that's how I see it anyway.:D

This could be a good buy for you also Eliza, as the machine is a few steps up the Chinese cheap stuff found around. Anyway the link is here (http://www.timbecon.com.au/assets/popup/productimages.aspx?ProductID=14168) so, up to you. Maybe these specials can be of interest to other people, I don't know..., what I know is that I have no business association with this firm!

This post would be probably better located at your other thread "Drill press" pens forum, but some how it belongs here too...!

Enjoy shopping...!:doh:

Hi Eliza

Sorry to see your mishap.:oo:

The pictures are worth a thousand words.

When I mount a drill chuck in the headstock I make sure the morse tapers are clean.

Insert the chuck in the morse taper.

Put a short piece of mild steel rod into the drill chuck .

The rod needs to seat all the way home or you could damage the chuck

I usually use the knock out bar.

Then give it a gentle but firm wack with a hammer.

This will seat the morse taper and it shouldn't come loose.

Of course you will also have to use a hammer to remove it from the lathe.

Yes I know there will be cries of horror about damaging the bearings ect ect.

I have been doing this for more than 20 years and have never had to replace a set of bearings.

Anyhow new bearings are cheaper than new eyes.

Cheers

Same in the tail Tim? That's where it was. I can see that it might help.

Forgive my ignorance, but why would you mount a drill chuck in the headstock of a wood lathe? I have done so in a steel lathe as there are some times that it is necessary and you can mount the material on the saddle and cross slide.

It seems a little impracticle in a woodlathe as the material setup proceedure would be very complicated and inaccurate.

Bad luck Eliza
I bet the lathe did not even say sorry:no:



I also hold the chuck when drilling and backing out the drill. keeping the morse taper pushed into the tailstock.

I used to hold the chuck but then one day. The drill jammed and made the chuck spin taking my hand with it:o 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:U

Forgive my ignorance, but why would you mount a drill chuck in the headstock of a wood lathe?When drilling long pieces like tool handles. You use the tail stock to push the timber into the drill.

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.

Tim the Timber Turner
28th April 2009, 10:38 AM
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.

Cheers
