Bonnie Klein has a machine to use on your lathe to cut threads into tiny
tops (awesome boxes when she's done) and the usual boxes.

I keep thinking I can make something cheaper $300 and use a router, edge
trimmer, Rotozip, maybe even a Foredom carving setup. Then again, I might be
trying to reinvent the wheel. Her's can be adjusted in thousandths of an
inch.

Thought I'd check with you guys.

Hello Tom,

Bonnie Klein's thread cutting device works best on her small lathe and
on lathes with 3/4" x 16 tpi spindles. I purchased my wife one for her
Bonnie Klein lathe plus an adapter to work with the 1" x 8 tpi spindle
thread of her Oneway 1018. It works very good on the Klein lathe, but
not too well with the adapter.

If you are looking for inexpensive, Craft Supplies Ltd. in the UK
sells a device that fits into the tool rest banjo that will cut
threads. It is a bit fiddly, but it does work.

Another possibility, if you can find one, is the Nova Ornamental
Turner, which cuts threads very well. It has been discontinued for
several years now, however.

If you really want to get very inexpensive, get a set of thread
chasers and learn to use them. I have thread chasers from about 24 tpi
to 4-1/2 tpi and can cut threads freehand as the lathe turns. You do
need to use good wood or use insets of good wood or plastic to hold
the threads. All of my chasers have cost less than one threading jig.

You can also make a thread chaser from a bolt or a threading tap by
grinding away 1/2 of the bolt to provide a sharp cutting edge of
threads on both sides. This becomes both an inside and outside chaser
and works pretty well. This is how I get a thread that I don't have a
chaser for. A fellow in Canada came up with this idea and it does
work. This is the least expensive threading device.

If you are serious about making threads in wood, I would also
recommend that you purchase a copy of my book, "Making Screw Threads
in Wood". It was published in 2001 and has been reprinted once. I
believe you can get it from Amazon.com, I no longer have any copies
for sale.

In my book, I tell how to make a device to cut threads that is fairly
simple to make and works similar to the UK threading rig.

Fred, I understand that Teknatool plans to (re) introduce the
Ornamental (new and improved). But then the remote for the DVR-XP isn't
out, the ..... I wouldn't hold my breath

Never used one, but there are a number of places that sell thread
chasing tools. Those are quite a bit less than $300, IIRC.

Otherwise, there is a plan for cutting spirals with a shopmade jig
that involves mounting a router carriage over the work and connecting
it to the spindle with a series of pulleys and a cable. With the
right size pulleys, I would imagine a guy could do this.

Also, if you check out Lindsay publications, you could take a look at
Dave Gingery's "The dividing head and deluxe accessories" (number 6).
This has plans to add a set of gears that can be used to cut threads
to a Gingery shop-built metal lathe- while it's unlikely to fit your
lathe as is, it might be an easier retrofit than you think with a few
idler gears added in. That uses a 3/8-16 leadscrew that pushes a
compound slide along the ways. I just finished making the compound
slide for a Gingery lathe, and it took about 20 hours to build it from
mild steel (Aluminum seemed a little dicey to me) by carefully
welding each part together slightly oversized to rough shape, and
milling them to the final dimensions on a Bridgeport. It was a fair
amount of touchy work, but nothing that is out of reach for someone
who is willing to hunker down and just do it. If you don't have
access to a mill, using Gingery's method of casting aluminum is always
an option- and if you make one of those, there's not much stopping you
from machining metal on your wood lathe, beyond the mess involved and
the limitations imposed by having a belt-driven spindle. It'd have to
ride on an improvised saddle with solid ways of some sort if you've
got a gap-bed lathe, but it could be done. (Though to be honest, by
that point you may as well make the whole metal lathe and have the
extra tool devoted to cutting your box threads- the compound slide is
the most difficult and time consuming part of the project.)

Cost on that project so far has been under $30, with some careful
scrap scrounging.

Of course, that is a lot of work- by the time you factor in labor, if
you're inclined to do so, you could have just bought the attachment
you mentioned.

[Bill N]

you can make a bonnie klein type threading tool - you trade time for $$ - do
this:

1. buy proper 60 degree cutters and chuck to hold in lathe spindle
2. buy cross slide (from harbor frieght), or a drill press vise with cross
slide
3. make tool to hold your lathe chuck to a piece of all thread with the
thread pitch you want.
4. mount allthread into a bracket containing two nuts with a spring between
them to remove backlash

now you are done - make threads

Hi Tom

Got one to make here., have to keep this short, on my way out.

Glad you posted that. You saved me a long search through my bookmarks.

That makes an 8 pitch thread, but I'd guess one of the guys in here
could machine up a 1x8 to (some other thread size) adapter to use with
any commercially available threaded rod. An ACME thread (flattened root
and crest often found on lead screws for metalworking tools) might be
especially suited to wooden threads. Might be able to adapt a finger
joint router cutter (might not).

Hi Bill

Jean Michel designed this jig, but he passed away, in 2005 I think it
was, he did have more good jigs on his site, it is still up, but I
think it is a good idea to download and save those files, as it might
not stay up.

http://www.atbq.qc.ca/jm2/

Jean Michel is the designer of the jig nailshooter shows pictures
from, mark kauder put those up I seem to recall, trying to help
someone wanting to build it.

As for the thread size, 8 per inch makes a stronger thread, but is
really way to coarse for a small turning, the thing is you need a way
to install your chuck onto the threaded shaft, so that was the reason
Jean used it initially, he was working on a finer thread setup, Bonny
Klein used the same thread as her lathe spindle had, I think 5/8"x16.
So if you want to cut a different thread you need an adapter that fits
your chuck to that "thread per inch" spindle, and you could then cut
the thread you wish, however than your material used to cut the thread
on is going to play a bigger role, for fine threads you do need a more
dense wood or use some other material.

Have fun and take care

Agreed on all points. Sorry to hear of the demise of such a talented
person. All of his jigs look great and I think he was on to something
with this one. Not quite done ... but a very good start. Thanks for the
link.

Much grist for thought here. Like the Longworth chuck, it is a good
design for a launching point.

As I get time, I think I'm going to toy with a couple ideas that come to
mind. I'll post photos when I have some results to show.

I think you'll find that Bonnie has a 7/8-16 thread on her lathe.

OK Tom.... not gonna tell you unless that damn shop is finally
finished! Yes? No?

Just kidding. ;^)

This is on my "to do list" which means it will get made when I get to
it. There have been a lot of iterations of this one, from using a
machinist's drill vise from HF to hold the Dremel/laminate trimmer/
router motor, to the one you see here where Al took a spare router
motor and mounted it in a wood case.

For me, I was going to get oneof those $15 laminate trimmers they have
at HF every other month and just take off the base.
That way I could have a completely dedicated tool.

You can see the jig here with pics about half way down the page.
There are some good discriptions there that should make this an easy
build.

http://www.cicaaw.org/image/tid/105?from=0

Like usual, the "hard parts" like the threaded rod came from Enco or
MSC, but I think many fasterner/bolt companies would have them or
could get them. The guys seem to have found 60 degree cutters to be
about optimum for this. I have read of many that have made this jig,
and a lot have added their own touched like indexers, etc., but all
seem to like it a lot.

With the rod being the guide, you can buy the thread count you want,
making it as coarse or fine as you like. For small boxes some are
using as small as 20 tpi with this setup! Cutting with a high speed
tool and a sharp cutter seem to negate the need to switch from coarse
to fine depending on the type of wood you are turning.

If you were in a club, you could split the cost of the threaded rods
as you only need a few inches. Then you guys could cut the rods, make
the rod boxes separately, and just change those out as you wanted.

I hope if you make one of these you will let us know how it worked out
for you.

Of course, there is Fred's book:

LOLLOL!!! Robert that "damn" shop STILL isn't finished :-)

Ceiling ply still leaning against a wall and lights awaiting. The list of
sidetracks for a househusband is long including the wife making a cascading
fountain of the bathtub upstairs (water's flow is gravity oriented BTW). She
might be 16 years younger but her senile moments make me feel REALLY old
then.

Finally said the hell with it and started turning on the big lathe
regardless of mess. I'm the same mindset as Charlie B - turning is cool.
Time passes as if mesmerized. I enjoy the attention to detail and finish on
some pieces.

And this thing of "tops", especially as boxes like Ms Klein does, is
fascinating. There was a top yesterday on the WoW site using Corian with
wood - very striking and the finial was beautiful. Grandkids at the wedding
recently were engrossed. My wife is great with pyrography and we want to
combine our efforts. Our club president has a tops challenge for tomorrow
and it'll be interesting to see how Bonnie's demo affected folks. Might be
able to post a link later.
