I support the hardened tips on the centres lots of stress on them.

Thanks Vic I ordered and got the dead center with hardened tip and live center just have not got round to turning anything yet too busy sorting workshop out so I don't waste time looking for tools and stuff am getting there slowly bought a Record bench sander so will continue setting up that tomorrow and have to turn off some couplings to fit on the camvac to set up the dust extraction system managed to get a few spalted beach blanks too.

Many years ago I bought stainless tube the right size for bushes for slimlines while I was visiting Tasmania easy to cut them in short lengths.

I like the way you can set the holes from above not stretched out on the bench still expensive.

If its the 12 inch roughly sized one I have one and ran dust ex to it and use it to square my blanks love it.
Peter.
Hi Peter I got the Record power BDS150 it takes 6 inch discs and 100x915 sanding belts it came with 60 grit disc and belt I bought a 120 grit belt and put 120 discs on that my old bench sander took. The old one was put to the dump as there was smoke coming from the motor it was a cheap old B&Q one I bought years ago think the make was titon any way the Record was easy to set up with a square and now I can square my blanks on it. The camvac tube fits on it no problem and gets rid of the dust.

what is the advantage of a half dead centre instead of a full dead centre? i have seen them before, but tbh never knew what they were for.
I don't know if there is any, just what I had when I took up spinning and always used it.
It still slips if not tight enuf same as any other.
I would think the disadvantage is it only come into contact with half of the tube and in inexperienced hands there would be more chance of damaging the end of your pen but in saying that I have never used one its just an observation and I may well be wrong
If you use a half dead centre in the tailstock it allows you to face the end almost to the centre with the centre providing support, although I have never needed to do that, but an engineering friend told me they were handy for that.
Peter
I wouldn't use one with wood, I would use a conventional dead centre if it was to drive and I certainly wouldn't use one in the tailstock with wood.
They don't spin in the tailstock unless it's not seated properly, so would be ideal for facing off with metal and as you say it would act like a drill with wood.

You would need to keep it well lubricated.

Hi Peter,
I got the centers off Arceurotrade one 60 deg hardened dead center and one medium revolving center which I am a bit confused with as far as lubrication is concerned. You can unscrew the end cap at the tailstock end to lubricate it and it has a seal at the front end of it which you can undo I guess you put graphite grease in the end but have also seen a very similar revolving center on u tube if not the same where the person recommended using 90 weight gear oil.
Tried to drill out bushings with a center drill but my center drill is far too small so might have to get an other one. I have had a look on Dan's website for his bushings but maybe this project never went ahead.
Its a cracking day up here and have promised to take Mrs Bob and my cameras out on a trip so more later.

Bob the grease is only if your using the dead centre in the tailstock to lubricate it so that the wood will spin on it and won't overheat but you will be using it in the headstock so no grease needed as for the revolving centre no grease needed there
I think Bob means putting grease or oil down the inside of the shaft that the live centre is on, I know mine recommends doing that to keep the bearing lubricated.
