Could somebody assist me in the method to cut spirals on a wood lathe?

I've just purchased a HAFCO WL-46 WOOD LATHE, not certain of what accessories needed and would like some general advice or if even this machine is capable to doing it.

Thanks

It is mainly done by hand.

Good Link :2tsup:

Yes sadly its either by hand http://www.turnersanonymous.org/PDFbarleytwist_reprint_feb_08.pdf

There is a simple device (name eludes me right now) which uses a router :doh: of course the Router Lathe http://www.woodworkforums.com/f221/router-lathe-114361/

or outlay $$$ for this machine.

If you just want a small decorative spiral ,the Sorby spiralling/texturing tool will do it, but you have to select the right wood .Do a Google search and you should find a video of using it.

Place a skew vertically on the toolrest. Lean it slightly to one side or t'other. Jab it into the spinning blank Curse loudly Change your pants

(Not recommended if you want accurate copy turning though! :;)


FWIW, 's method turns the best looking spirals/barley twists. IMO. A router lathe just doesn't leave the same crispness of detail... unless, of course, you finish by hand. In which case, why spend the money on the router lathe in the first place? Doing it by hand can be just as fast, with a little practice.

Well... OK... maybe a LOT of practice. :U

Yes, a decorative spiral can be done on a spindle piece as Ted posted.

With the Sorby, see the Spiralling vid here (http://www.robert-sorby.co.uk/movie-clips.htm#sts)

When kept sharp, this does a surprisingly good job even on soft woods.

And for some reason, a less than fine finish seems less obvious with these spirals or stacked decorative beads ('beehive') than you would expect.

Did that today by accident!!! Drove the skew into the chuck jaw!! Whoops, get the file out, dress the ding out, then change your pants. It all happened in an instant.

Well fancy that!! And all I was trying to do is make a glue block so I can make a lid for my first hollow form.

Yep, I will post pics for critique.

I still feel like a bit of a dill though.

Here ya go. This is what happens when you don't have proper control of your tools. Nice spiral though.

LOL.

No, that's a gentleman's spiral.

Now a catch with a 1 1/4" skew will give you one that's almost too big to photograph :D

G'day Colabus and welcome to the madhouse!!:2tsup::2tsup::2tsup:

Some start, monkeying around with "spirals".:D

By the way these are NOT spirals, they are helixes"

Just thought I'd be pedantic.:q

I turn the vessel, leave on the lathe and cut the sprials by hand:
First mark lines horizontally then vertically and cut by hand
See if it shows.
