Dust Extractor tube arm
Hi all. Hopefully this makes sense.... I have just run some dust extraction tube to my lathe and I want some kind of movable/flexible arm so I can move it around where I will be most effective.
Is there some thing I can buy or has anyone come up with a home made job?

You might have to adapt an overhead d/e table saw arm idea.
An internet search should give you some ideas.

This was my bodgy job but it works great, not the easiest thing to move but....Life expectancy would grow by leaps and bounds if green vegetables smelled as good as bacon.

Add a bell mouth to the inlet. You can turn/make your own.
I hook it onto the banjo and adjust its position to give optimum uptake.
When sanding I get it up very close to the source of the dust.
My particle counter tells me it does a very good job.

The Bell mouth hood is THE most efficient hood - it allows you to locate the hood inlet at twice the distance away from the work and get the same suction as not using a hood.
I have mine on a sliding arm attached to the bed of the lathe.
And here it is in action.

Bigger pipe is always better.
That said, I have both the Carbatec unit referred to earlier and the Loc-Line unit direct from the USA.
The Carbatec unit requires a frame/holder to keep it where you need it.
The Loc-Line unit stays exactly where you place it and is brilliant by comparison.

You can source the Loc-Line from the Australian distributor, but at around $250 AUD located in Melbourne it was not feasible. I got mine from the USA for around $65 AUD using someone who was importing something in a container. This was some years ago.
The attached picture shows my Loc-Line unit in the background. Taken when I was setting up my MAX SAVER 3, bowl saver/coring unit.

No time at all to setup. Most of the time is in making the bell mouth (in placcy or wood), but recommend that you have that whatever arrangement you come up with. I prefer to use wood for my BMs. An easy task for a wood turner and nice smooth edges are more forgiving if it comes in contact with an almost finished piece.
Works best for me with outboard turning when used like this, which is mostly what I do, but I can position it coming in from the back of the lathe for any inboard turning.
