Drilling blanks using lathe

[Baldy]

HI guys looking for more help. I am not quite sure if I am doing something wrong.. I got my drill chuck from axminster this week and tried to use it to drill a blank. But when I got a 1/4" in seemed to grab the bit and pull the tail stock out.. I had the blank secured in the Chuck which is a supernova 2. Is it because I am not using pen jaws?

Thanks to all in advance

How is your chuck mounted to the lathe, morse taper? Straight shank?

You will need to use a draw bar, fitted to the mt or straight shank to hold the chuck in position.

This is a threaded bar screwed in the end of the mt and secured through your tail shaft. If your lathe has not got a hollow tail shaft then you may not be able to do this.

If you research lathe drawbar on google this will give you pictures and ideas of what one is or looks like.

Hope this helps

one thing you have to watch with the drill chuck in your tailstock, if your lathe has the auto eject of mt centres, that you don't wind the quill too far back so that it's trying to push your drill chuck out of the mt making it loose. it's happened to me a few times while drilling. also if your lathe speed isn't set fast enough the drill bit can dig in the blank. obviously you don't want to have the speed too high (500-600 rpm should be fine) and go slowly. if you do have a morse taper on your drill chuck and the problem persists you try tapping the chuck into the mt with a mallet to make it stick. i also found that the jaws that cone with the chuck it's difficult to get the blank perfectly centred so i got the sorby pen jaws and never had a problem with drilling off centre. some woods cause the drill to wander anyway. zebrano was one that i couldn't drill straight at all.
hope that helps

That is what I do Ray !!!!

If it is a Morse Taper Baldy, this should work fine, i have drilled my blanks on the lathe for years using this method with no issues so as Ray says you just may need to tap the drill chuck in a little to help hold it secure ..

What Ray said

 

[Walter]

What Ray said sounds about right to me too. Also check the Morse taper in the tailstock and on the chuck are both clean. When the taper is properly seated you should not be able to turn it by hand or pull it out.

 

[Woody]

Have you done the kiss test to see of your lathe is running true put your drive in the headstock and your centre in the tailstock bring the tailstock up to the headstock to see if the two points come together if its not this will cause your Jacob chuck to vibrate loose whiles drilling I also drill as Ray said

 

[paulm]

I use the pillar drill for my blanks but if I drill anything using the lathe I always hold the chuck as its drilling.

 

[silver]

I agree with Ray and every one else that this has become an acceptable method of drilling using a lathe.

However, it is not the safest method and we should be encouraging everyone to use the safest method possible.

USE A DRAW BAR. Then it won't and can't come out.. Impossible.... Simple init.....

the only problem with this is the standard Jacobs chuck is supplied with a morse taper, mine is an axminster, and the end of the taper inside the quill doesn't have the means to attach a draw bar so you'd have to buy one and I've never seen one and making one isn't so easy. just a thought.

 

[Woody]

Axminster sell them in there metal work section with a 3/8" thread they only come in 2 or 3mt but if the lathe is not set up correct the chuck can still be vibrated off the arbor so the problem will just be shifted to another point Stub Arbor - Tooling for Milling Machines - Milling - Metal Working | Axminster Tools & Machinery

 

[Walter]

I am not going to get into this debate again. My views have been expressed previously.

I will be demonstrating how I do it as part of my York demo and explaining why it works. If you want to do it another way that is fine. Just stay safe.

I don't use a drawbar, but that is a perfectly good way of preventing the chuck from parting company with the taper.

 

[Woody]

Me to Walter my main concern is has Baldy tried kiss test it is a new lathe and he has never turned before so both ways wont work if his lathe is out of true

Very true. Worth checking.

Didn't really mean it Brian I love reading your comments

That's true Woody, but Brian's comments are quite mild compared to some I have seen on other forums. I have known established members of some forums (not woodworking ones) to get extremely abusive towards newbies who come onto "their" forums and have the temerity to waste their precious time by asking questions that have been asked before.

This forum isn't like that, everyone here will always try to help. Provide conflicting advice and argue with one another in the process, but help nonetheless.

That's why I am pointing it out dad.
Not to be rude but to save a repeat debate which hasn't worked.
