They're arms that drop into your banjo at the bottom end, thread into your chuck at the top end, with a pivot in between. Designed to allow you to carve, texture or decorate a piece while still safely held by the chuck.

There was someone in Melb making these a while ago; wonder if anyone can advise on a source.

Ern,

Theres a guy in Newcastle that has patent out and makes them for about 150. Bruce Leadbetter had a version at one stage as well. They are not very complicated.
A piece of round bar or pipe to fit the banjo an arm that bent down on an angle for easier access and weld on a insert that suits your chuck.

Gil,

Nice one! looks better than any I have seen around and not that hard to duplicate. Should keep Ern happy.

Gee, Hughie, if Ern is happy, we are all happy.:D

That's exacly it Gil. :D

Thanks Hughie. I made a start: 1" steel rod for the banjo, and a 30 x 3.5mm bolt for the chuck. But the pivot point was the crunch. The big chuck weighs a bit, as would the piece, so the pivot would have to be able to hold a fair wack. I can see why Bosch went the way he did.

Hmm, maybe something from the car wreckers ...?

Neil Scobie has a similar device shown in his latest DVD's. He may be worth a yell to see if he has a plan for one or a source.

Salty, thanks, yep, think he referred to the Bosch during his demo of turning a 3-sided bowl as broadcast yesterday on the WW channel which is what started me back to thinking about local or home-made options.

Way out of my means though; Gil, our $ is worth 3/4's of yours and the postage is punitive.

Guess it's clunky but if nec I can just clamp the 30mm bolt in the vise.

But clunky goes against my interlocked grain; that demands something elegant, cheap and achievable with two toothpicks and a file ;-}

Will admit to being somewhat stir crazy with the right paw out of action ... might explain the above; can't ski, can't ride and can't turn. Oh, can't work either. Might account for why the shed got a dusting today and the saw-tooth bits got a touch up.

excellent idea, never seen anything like it, have to see if I can find/make one.

The one Neil has is more flexible in its movementsas it can pivot in all directions easier than the Trent Bosch one

He was trying to get someone to manufacture the design for the guy who originally made the one he uses.

It can be put into the banjo from the top or bottom depending on what you are trying to do.

Ern, Theres a few sites around to pick up bits and pieces. Basically you need a couple of those clamps we used to see on beach umbrellas.....:D oops I am showing my age again.

You can make em with two flats discs/plates/washers and put a semi worn out 4'' steel cutting disc between them. This acts as the brake, pull em up with a bolt.
Have a clamp like this, or like the Bosch one for that matter. At both ends of the rod it gives the oportunity to lower the bowl right down into your lap so to speak for easy carving. I have seen them like this but cant think where

Many thanks Hughie; much appreciated.

Yeah, I remember those beach umbrellas. Maybe also an old type motorbike steering damper - the ones that ran through the headstock.
