Wooden thread cutter

Posted by jerry on September 18th, 2004 — Posted in Journal, Woodwork

Woody stuff…
One of the things I picked up at the wood show was a thread cutter for wooden dowels – this will open up a number of possibilities – particularly for building embroidery frames with adjustable tension. The prospect of collapsible or adjustable-height stools has a certain appeal too – especially for camping at folk music festivals

I have since bought the matching 5/8″ drill bit for the 3/4″ tap to match the 3/4″ thread cutter. And they work a treat. Okay, so I put a square nut on the end of a broom handle, but it’s a start!

And I have been trying to set up my dovetail jig for ages – and managed to destroy the bearing on the dovetail router bit – so a trip to Carba-tec got me a replacement bit (AUS$29.95) that’ll teach me to release the plunge on the router too soon! You would think that a simple chinese half-inch dovetail jig would be easy to set up, but I needed to see the demo at the wood show to learn that if the offset for the vertical piece is inboard of the horizontal piece then tearout is much less of a problem. I have also learnt to use backing pieces to stop this problem altogether… oh well we live and learn 🙂

Hi Fred
It’s a bit of an odd size these days, but you could try carbatec – they do stock thread boxes. They have them available in sizes of 1/2″, 3/4″, 1″, 1-1/4″ and 1-1/2″.
There may be a USA woodwork suppliers – try searching online. You might also try secondhand tool sales.

in the US the beall system is a bit different than the standard thread box it uses a router but it turns out excellent threads .The type of wood you use plays a big part in how satisfied you’ll be
