The scroll and jaws of the 3-jaw lathe chuck tend to get jammed with chips
and require a rather tedious cleaning every few hours of use. Is there
some trick to keeping the chips out?

A cover plate for the hole, if the stock is short. A plastic collar if the
stock goes thru the spindle are about the only options, unless you can put
purge air on the chuck.

You can't 'idiot proof' anything....every time you try, they just make
better idiots.

Aaak!

Isn't the compressed air likely to drive the swarf deeper into places where
you don't want it?

If that be the case, perhaps someone can explain to me why my 8" 3 jaw, put
in service in '67 on my Sag 12 Graziano, and used on a commercial basis for
16 years, is still functional quite well, thanks, having been dismantled
only a couple times for cleaning in all that time.

The use of air in the hands of someone that isn't a moron is one of the
finest of methods to keep chips away from where they are not desired.

The negative attitude of the use of air on machine tools is much like the
false value placed on Bridgeport mills (I own one, and have purchased two in
my years, so I'm entitled to have my opinion). Pretty much just a
housewife's tale, assuming care is taken for application.

For some chucks, you can buy some neoprene-pieces that fit into the chuck's
slots for the jaws. Simple punched pieces about 3mm thick. You always can
make your own.

Used with due care , it is the best method I've found . I also almost always
cut dry , drilling being the exception . Coolant introduces another whole
level to clearing swarf ...

Coolant can serve to peform the chore as well----depending on circumstances.
A clean flood works amazingly well.

Maybe when I have more room . A guy can only do so much in an 8X12 shed

Yup , I only heat while I'm out there . My wife must have some Scottish
ancestors , she's frugal ... make that VERY frugal .
I do keep a hundred watt light bulb burning 24/7 , helps with the
humidity but it won't keep it above freezing .

In my barn shop, I thin the coolant with anti freeze. Just the used stuff
from the cars. Works fine. 1:4 ratio gives about 0 freezepoint. That's
coldest my shop gets.
