Do you have any ideas on what type of jig it was? There are several different types that pop into my mind...

1. An arm & wheel assembly that clamps to the end of the turning chisel. (The whole assembly sorta looks like a G-clamp). It's adjusted so that the gap between the wheel & tip of the tool is the desired thickness of the dowel.

2. A steel adapter that replaces the live-centre in the tail-stock. This works much the same way as hammering a peg through a hole in a steel plate, or using a drill-press, except you wind the tailstock instead.

3. A "pipe" that clamps into the banjo instead of the toolrest. It's set so that the centre is offset a bit from the headstock, which contains a router-bit in a jacob's chuck. You feed the peg through the pipe, rotating it as you go. (I'm pretty sure this type of jig was originally designed for router tables :wink:)

There are other methods... I prefer to simply turn between centres and use calipers. If speed & accuracy were vitally important, I'd prefer to use method #1.

Spped and accuracy is very important.. Im trying to redisign my scarfholder making process to cut down on the time needed and the number of times i have to chuck the wood. i see that what takes me most time is making the 3-4 mm traight section of the stick.

Pictures ?? I was thinking of something like a modified pencilsharpener ??

#1 would be my choice there. Sorry, no pictures... I can't think of the right keywords to do a search. :-

But it should be possible to make your own if you have basic metalwork skills.

As I said, it looks like a G-clamp. Except the tool (usually a square scraper) pokes through where the thread would be, and is locked in position with a thumb-screw. On the other-end of the G-clamp, where the "flat" would be, is a roller.

Hmmm... in effect, it is a heavy-duty pencil sharpener! :)

http://www.woodworkforums.com/images/icons/icon3.gif ! That's the bloke to ask! I'm pretty sure he has a couple of 'em and could tell you the "right" name.

FWIW, I found this: http://chestofbooks.com/crafts/popular-mechanics/The-Boy-Mechanic-1000-Things-for-Boys-to-Do/A-Dowel-Turning-Tool.html

...but that's overly-complicated compared to what I'm thinking of.

Thank you both !! the idea i have i something like the link
http://chestofbooks.com/crafts/popular-mechanics/The-Boy-Mechanic-1000-Things-for-Boys-to-Do/A-Dowel-Turning-Tool.html

but with the plane part angled like a skew more og less. that should give me a very quick and nice finish tor the pin part..

I have the sorby sizing tool but thats not an option leaves to rough a surface..

i will keep working and post if i find something better than what i do now :-) (13-18 minuts pr stick)

Check out the gadget on this link http://www.carbatec.com.au/joinery/tenon-jigs-cutters/veritas-power-tenon-cutters If you could modify it so the tenon could continue through the other side it would soon become a dowel and should have a pretty good finish :shrug: or this one http://www.carbatec.com.au/joinery/tenon-jigs-cutters/veritas-tapered-tenon-cutters would leave you with a small dowel out the narrow end. The principle they work on is the main thing - shouldn't be too hard to come up with your own version - - - - oooops - I feel a project comin' on :B

Killer beast, to make 3mm dowel is easy. Drill a 3mm hole in a piece of steel. Next turn your timber down to 3mm plus a little bit and then, with the lathe running pass the steel with the 3mm hole along the length of the timber. This will take the timber down to an even 3mm. This is how dowel often was made except oversized timber was hammered through a hole in a stationary piece of steel. For safety purposed you might like to put a handle on the steel with the hole in it. Simple, cheap easy to make yourself.

Yes, and don't let go of it until you've stopped the lathe. :o. Nice idea Brendan, although I'm not sure how I'd go turning any reasonable length of timber down to 3mm. Maybe short pieces? Have you tried it?
