New Jacobs chuck....

[gothycdesigns]

Hello, been a while since I've been to the forum. Well I decided to get a Jacobs drill chuck for my tail stock. Thought this might be better for drilling out the blanks. Since I have not used one before. Any pointers? Suggested speeds fast or slow and such. Till now have used my drill press but does tend to walk and then I get a off centered hole by the end on some materials. I have the drill press bed leveled as best as I can.

Thanks for your time and any suggestions. Also would there be any tutorial videos showing this process?

P.S. I have a Nova 1624-44 lathe that i'm using this for, if this helps you to know what I am working with. The jacobs chuck was purchased at local Woodcraft, can't think of the brand at this moment. But it was the one most recommended to use. ThX !!

I just recently added a 4 jaw chuck to my lathe ... and let me tell you.
I dont ever want to use a drill press to drill square blanks again!
What a difference.
Your days of blowing out the back side of a blank are over.
I am sure you will see what I mean when you start drilling on the lathe.

For the larger size holes I prefer to drill a hole then bore out the hole with a small boring bar.

I use the standard key type chuck in the tail stock but my buddy likes a key-less style.
Your choice ... as they both seem to work well.

I like drilling on the lathe. Your setup will help if you watch a few things.
Keep the bit/blank cool, as usual...heat is an enemy.
If you feed too fast, too deep, per "peck" you can still run the hole off center, just like a drill press. It gets worse as it gets deeper, of course.
You need to retract the bit all the same and a lathe quill is not half as convenient or quick as a drill press. So, take a little more time and you will be able to get the good results you are after.
A center drill before the drill can provide a nice starter dimple to keep your drill from skating on initial entry, also. Not a must if you ease the start, but can be of help.
I use around 800 rpms, that seems to work fine for me; more will cause more heat.
Lathe drilling can be quite accurate, just give it the right opportunities to shine!

Sweet. sounds good. exactly what I like to here. As for drilling on the press I've never been to harsh. I do small increments as recommended. So cool. In a sense the same common sense as use for drilling with a press, just better results.

Also is a brad point bit still recommended? Thats what I've been using before, at least the 7mm. Can you get a brad point in 10mm. probably a dumb questions, but frankly I've never really looked for one larger than a 7mm.

800rpm I'll keep it in mind. I didn't think over 1000 was needed. But if its a good happy medium for you, I'll try it out. I got the lathe last Nov. and love it. a big step up from by prior lathe from....don't laugh....Harbor Freight. but it did just ok for a few years. But much better now on the Nova.

ThX !!!

Lathe On !!!
