Using a drill press for axle holes?

[bracketracer]

I hate you chromegsx. ;-)

So one ruined chuck, one new chuck, and god knows how many hours later I am down to ~.001 or less runout.

Couple things I learned along the way (this will probably be in the "well ... duh" category for most, but maybe it will help another newbie):

* Unless you know what the hell you are doing, or you are willing to chuck the chuck, do not file the jaws. Just like chromegsx warned, I thought I was filing down the right jaw but I just kept making things worse. It got to the point where I could literally see space between the pin gauge I was chucking and one of the jaws. By this time I had resolved to buy a new chuck anyways, so I kept working at it - and kept making it worse.
* Chucking technique is everything - at least with these cheap chucks. Maybe the "super chucks" are more consistent, but before I learned the best way, I could chuck the same pin gauge at the same position and the runout could vary between .0005 (nil) and .005 each time. This was true even with the new chuck. Here's what I have to do to get 0 - .0015 runout:

1. Chuck the bit/pin gauge. Slowly hand tighten as much as you can.
2. Check the runout - if more than .0015 then remove the bit/pin gauge and repeat step 1.
3. Using the key, tighten the chuck by making tiny turns in each key hole. By tiny I mean maybe 15 - 20 degree turns. Do this in each key hole and go around at least 2 times (6 total turns). If you can't make it around twice before it gets too tight to turn then you probably were turning the key too much.
4. Check the runout. It should be .0015 or less. If not, remove the bit/ping gauge and start over at step 1.

At least this is what I have to do to get ~.001 runout. If I follow this process I can usually chuck the bit with ~.001 or less runout the first or second time. Keep in mind this was on a brand new (budget) chuck. I wonder is this chuck faulty or is this pretty typical for budget chucks?

In all seriousness, thanks chromegsx!

You could have just chucked the chuck and put in a collet holder instead! Search for ER collet and whatever taper your spindle takes (like "ER collet MT2").

Glad you got it fixed! /images/boards/smilies/smile.gif

LOL! Very timely post BR!

Way to pay the frustration forward Chrome.

LighninBoy. There are a lot of religious people on here. Would you be so kind as to be more careful of the things that you type? Thank you very much!

Yes,I have been yelled at by DAD (Kinser) too.

In the same thread too. Maybe we need to move on.

I've asked very nicely everytime and I've never yelled. I'm sorry if you're offended that I ask to watch the language and innuendo's. I spend a lot of time here and I prefer not to have those words running through my head.

True Kinser.
Capital letters, or bold typeface would be indications of yelling and I never saw that from you.

Rocket,
Kinser merely gave you "the stern look".

I know what ya mean Kinser. That is why I stopped watching those reality TV shows years ago.

I agree, if you can figure out the innuendos your already demented. If your kid 6-10 years old knows what we are talking about, Sorry, I can't help you there.
It's ok I still like you.

P.s. Yelling, sorry wrong word.

I like everyone here with the exception of maybe one guy (BH, lol) . That's why I hang out here.

 

[Rocket car]

We like you too.

especially this time of year.

Oh man!

BH is the best! I can hardly wait to hear from him again.

I like how everyone joins together at that moment. Nothing brings people together like a common enemy.

I had thought of that, but collet holders for JT33 tapers are rare and really expensive. I did try a collet adapter (a collet holder with a shank that can be chucked in a 3 jaw chuck) - but that doesn't really solve anything as any runout from the chuck/collet holder connection is magnified by the extra length of the collet holder.

I'm an absolute newbie and have no intention of making waves. I want to be respectful of the regulars here and the culture you all have fostered. That all said, I have no earthly idea what was offensive in my posts. Was it the word "hell"?

 

[txchemist]

Lightning- I am sure you meant no harm, but

Religious profanity is called blasphemy. The verb is to blaspheme and the adjective is blasphemous. Saying “God!” or “Jesus Christ!” as an expression of surprise or annoyance is considered by many people to be blasphemy, mostly because one of the Ten Commandments says not to use God's name "in vain" (without substance or without intended relevance). Swearing oaths can also be considered wrong by some who follow Jesus' teaching against swearing oaths in the Gospels (such as Matthew 5:34).

and I know in some areas this is not considered as meaning disrespect, but in many areas it is considered to be blasphemy.

I have the same reaction as Kinser to it- I probably am not alone. Even if it does NOT mean the same thing to you as to some others, take it into consideration as I'm sure we would if we found out many were offended by something we took for common expressions.

JT33 would be the taper of the arbor your chuck mounts on I think? You can't knock out the arbor and replace the whole thing? I hope it's not a Jacobs taper up in the spindle, it would be very short! You might have an arbor like this?

The few drill presses I've messed with have a slot in the spindle where you drive a wedge to knock out the arbor and chuck together. Then you can replace it with something like this:

txchemist explained it better than I could have. Thank you! /images/boards/smilies/smile.gif

Ok, I see. Its unusual for me to use those kind of words anyways in my writing - two in a row is totally out of character - so it will be easy to abide your request.

Yes, JT33 is the taper where the chuck mounts.

Ok, I see where you are coming from. Unfortunately, my press doesn't have that slot. I'd have to do some fairly invasive surgery on the press to get the arbor out. Might still be worth it though, so I'll have to think about it.
