Boring Deep Holes
 

Can someone give me some tips on boring deep holes for pepper mills? I plan
on using Forstner bits with extensions and boring on the lathe. Anything
else I should do of be wary of? Thanks.

I have had good results with that setup. Use your slowest speed and use
compressed air or a shop vac to remove the shavings and dust to prevent
heat buildup, especially if your are using green wood. Make sure your
forstner bit is sharp.

Barry

you should also make sure the bit is going into the piece at the center at
the outset. The best way to ensure this is to use your gouge and cut a cone
ito the end grain - that will get your F Bit started in a place where it can
not wander too easily.

Do you ever have a problem with the bit wandering? Do you bore from both
ends and meet in the middle, or just from one end?

Hi Barry

How deep is deep holes, ? for just a couple or three four five six
inches, in dry straight grained wood a forstner bid should do just fine,
backing it out every half inch or so, the problem with most of the
extensions is that they are a floppy fit, but if you first go the max.
with the bid without the extension you might still be OK, if you plan to
go for 10" or 12" or more you should go with a D drill bit like Leif
suggest, and I would drill the hole first before shaping the outside so
if you are off center a hair it would not matter, O yes keep the speed
way down.

Have fun and take care

I drilled out a couple of lamps a month or two ago, and your task is
definately not enviable. I was drilling into wet paper birch end
grain, and the forsner bit got extremely clogged right off the bat.
So, I switched to an auger bit, and it was the same story. Finally
resorted to the old standby set of spade bits, and they did the trick,
though I had to drill in as deep as I could, then back it out and
knock the piece against the bench to clear the long, stringy fibers
out. I repeated that about 20 times or so, and finally got them
cleared enough to run the cord through. Hopefully you'll have an
easier time of it than I did! Spade bits will do the trick, they're
just not quite so clean as the Forsners.

Either way, just make sure you don't ram the bit into the chuck! :)

Good luck!

We did a bunch of pepper mills a few years ago, and I went the other route:

I drilled the square stock, (some 3" x 3" walnut that the client had), in the
drill press, and then mounted the blanks on in a chuck and live center using
short tapered dowels... worked great..

Now that I have a larger lathe, I might try drilling the mills with the
tailstock chuck, but at the time that DP just seemed more accurate...

BTW: we used Precision Chef grinding mechanisms and rods, and they worked really
well....YMMV

You might also try looking on ebay for a gun drill that is the diameter you
need. I use gun drills for making flutes and they are tough to beat for deep
holes. The gun drill that you want is one ment for drilling metals that have
one or more holes running the length of the bit for coolant. But you are not
going to run coolant through the hole, you are going to run compressed air
at about 5-10psi. The drill bot is held with a pair of vise-grip pliers. A
short starter hole is mage using a forstner bit or a small square end
scraper dead on center. The gun drill will bore a hole dead straight and
leaves a great finish inside the hole.

I bore from both ends and meet in the middle.
Usually aligns very well. No problem if it doesn't.
