Precision Bushings

[TaylorsMirfield.co.uk]

I like many on here follow different forums and Facebook pages. One topic that keeps coming up on the US pages is precision stainless steel bushing which are also designed to be used between centers.

Would this be of interest to people?

Erm no bushings go between blanks on mandrels, whereas, bush's are where people go 'walkabout in'; near to places like Tennant Creek in Australia; you might have heard of it, its a place where wood turners complain about the heat.

Sorry Mark I'll go find my hat and coat.

I don't supposed you could elaborate a bit more please? I don't follow Facebook etc because of its inherent insecurity.

The US seem very good at coming up with new ideas. one I have seen and like is Stainless Steel made bushings. Some are made with no center hole but instead have a 45 degree inverted cone on the back edge for your drive and tail center to go into. Some have a hole and also the inverted cone.

I'm not entirely certain why you can't use normal bushings between centres. They've all got a hole through the middle - all you need is some sort of friction drive such as a fixed centre at the headstock and a revolving centre at the tailstock. Sorry to rain on your parade

Sorry I still can't see it, if I turn any pen with a nib end blank and a clip end blank, I need a bushing in the middle, BUT if I have bushings that somehow go into something in my tailstock and headstock and the middle is unsupported I surely must get inherent hysteresis (Wobble for want of a better word), do you have any pictures or schematics?

Now offer me bushings that don't wear down with sanding and I will be seriously interested. BUT anything that costs lotsa dosh will get Dragon Ops breathing fire....

I am also looking at titanium bushings so this might answer your reduction of wear. Initial figures are looking around the £6 per set mark.

What about case hardened bushes?

Drill bushes are case hardened and are far more resilient than stainless steel or titanium.

 

[Penpal]

Like Shakespear said much ado yes I agree there is so much to be said for neat sleeves of metal drilled to provide both spacers and sizes to turn to there is to problem of mandrel sizes then.

A wonderful thing would be a proper sized mandrel with accurate bushes if they were reamed for between centres a bonus ( one fits all approach) with plain spacers for those that turn a full pen at the one time. So many misfits abound.

I admire you taking this on but there are so many pitfalls. Good luck Dan.

I am well versed in bushings, esp with precision TBC. Ti is not viable since some use carbide and Ti is a soft material use. You can use heat treatment to yield good nick free from carbide tooling however first drop on the ground it will shatter into a billion pieces.

 

[EStreet]

Length and diameter is highly critical in bushings. You have a side to side wobble along with the vertical up and down motion contend with.

OK before this goes crazy, let's clear a few things up here.
Many of you will disagree but I don't care cos I know I am right init?

The product is called a bush, bushing is what you do with it.
Unless your American in which case a tyre is a tire, burr is burl, grey is gray, and your brother is your lover, you need to be forgiven for not speaking English.
Bush's grow in the ground, bushes are machine parts, spacers / packers / shims for rotating or moving parts.

45° angle on bush is not gonna mate very well with a 60° centre, probably worse than having a hole in the end which should also be tapered to suit the mating parts.

I close with saying why should I pay extra or have especially made precision bushes? They should all be precision made from the word go, if they aren't, complain, smarten your act up and get them right to start with.
