Too Many Chips in the Scroll when Boring

When using a boring bar, the chips are pushed into the bore.
I’m curious what you do to keep chips out of the scroll on a 3 jaw.
I just cleaned it, now I have to do it again.
(On the other site someone would say, “don’t use a 3 jaw”)
Ball of foil stuffed into the bore?
I appreciate your ideas.

I may be doing it wrong, but on my el cheapo Chicom 3-jaw scroll chuck, stuffing something in the bore will keep the bore clean, but it won’t keep chips out of the scroll. There is a gap between the surface where the through bore starts and the back of the jaws where swarf can get into the scroll and/or the jaw engagement grooves. I recently did some boring and got some swarf in the scroll that made the jaws difficult to adjust. I removed the jaws and brushed the scroll grooves out with a small paint brush as I slowly rotated the scroll with the chuck key. That cleaned it up and I didn’t have to take it apart. ymmv.

Hi Guys,

As far as trying to keep the bore clean, I don't bother unless I need to put something in the taper or use the lathe handle. Then I use a pull through, in my case a 12 bore brass shotgun barrel cleaner. I have used strips of sponge on a length of string as well.

Keeping the scroll clean is a matter of removing the jaws and giving them a good brushing with a brass suede brush. The scroll is cleaned with a wooden chopstick, shaped at the end to fit into the scroll groove. Inserted at the outside edge of the scroll and twisted slightly so it contacts the bottom and both edges of the scroll, whilst winding the scroll so that the chopstick moves any debris to the center, where I can just brush it away.

Afterwards oil both the scroll and the jaws, then refit them. Job done in a few minutes.
 
This is a real pain when doing a through-bore and I hate cleaning chips out if I don't have to because I'm lazy. I normally use a longer than required piece of stock and do a blind bore long enough to give me the length I need after its bored out and then I part off the bored part I need. I waste a tiny bit of stock but not much. With proper feed you get big spiral chips but no matter how careful you are, there will always be some little ones.

I am also careful to stuff a rag into the spindle taper to keep crap out. Yes, you can clean it but that leaves scratches in the taper, even in a hardened spindle. Wow, that Mikey is anal!
 
Just thinking but wouldn't modeling clay pressed in before tightening the jaws be a good stop gap???

Hi, Just think for a minute ! What is going to happen to the modeling clay or plasticine when you try to remove it ?
Small, even minute amounts are going to get smeared all around the scroll, even if you remove the jaws and clean the teeth, there are still going to be some of it settling in there, ready to pick up particles that you can't get rid of without stripping the whole chuck.

Even using the cleaning method I suggested, there are still going to be particles of material that you cannot get at and remove. I strip and clean my chucks every couple of years and the amount of debris that gets in there you wouldn't believe, and I don't use my lathe on anything like a regular basis.

If it's not jammed in the opening I doubt it will stick to the metal accept as a glob . But whatever I'd try it on mine if it was a problem . Or shove a paper towel in each area.
 
Chop sticks-move chips toward center, I like it.
I am glad to hear i'm not the only one with this time consuming clean up.
I don't know about all 3 jaw scroll chucks but my scroll is exposed.
I like the blind hole too. Some applications will allow for it.
I may try a ball of foil.
