Dave Hout Threading Attachment

[Brad Kimbrell]

Hey guys, new turner here and trying to soak up as much as I can from the threads...

I saw Dave Hout hosing a show called "Woodturning Techniques" on DIY several Saturdays ago. He was using an electric machine to cut threads around the inside and outside of a turned box.

I have searched the web to see one of these machines and a price but am unable to find one???

Anyone out there know what this is and if it is worth whatever they get for them?

Thanks!

....... I saw Dave Hout hosing a show called "Woodturning Techniques" ............

I bet that he just hates it when that happens :D.

Seriously, it sounds more like Dave Hout may have been using a threading jig. Bonnie Klein sells them on her web site and Best Wood Tools also has a similar tool. The ones that I am thinking about mount on the bed of a lathe, but they are not electric powered machines -- the cutter is installed in a Jacob's chuck which is driven by the lathe's spindle. If you buy them, they are terribly expensive, but they are not vry complicated and you can design your own version for a fraction of the cost of buying one.

FWIW, Richard Raffan uses a threading machine in his "Turning Boxes" DVD but I do not recall the brand name. It looks expensive. I'd be surprised if it was priced under a couple hundred.

There's some wood threading tools in the new Packard woodworking catalog. Doesn't seem to bad expense wise. All manual, no electric power needed except for the lathe.

They don't give a source for the threading widget on DIY's website, but it looks pricey, and definitely not shop-built (unless you're a master machinist).

The cutter itself is spun by the lathe, held in a collet chuck. The rest of the widget replaces the tailstock and has micro-adjustments for positioning and gears to move/rotate the workpiece into the cutter at the precise rates needed to cut the threads. If I remember from the show, the threads he was cutting were very fine, on the order of 15-20 TPI.

Lee I think you are right on the DIY threader. Also the one Raffan uses I think is a Taig lathe.
