Handy with a Lathe ?

[FluffyChicken]

ooo, lots of technical talk, fallow it (well sort of ignoring the technical terms and taking a guess at what you mean)
Think i'll go see what this lathe is and err see what tool are with it.

Dave, will do that if I cannot give it a go myself, charge much these Barton boys
I also have an intact one in the other leg of the fork.

As long as you've got enough stock to stick out of the chuck to clear the toolpost/carriage (without any vibration/chatter), you could do it all in one set-up turning the smaller OD w. a L.H. tool bit.

He bored out the centre of some wheel adapters for me and he didn't charge a penny. Wouldn't even take a contribution to the tea fund.

Just make it clear you are trying to keep a classic push bike going and you know nige lewis!

Yes, you could indeed,. and a running centre in the tailstock would take care of the overhang/vibration issue

No soft jaws??
Use two thin bits of wood

The idea of using soft jaws in a lathe chuck is that you are able to bore the jaws to a) suit the shape/diameter of the workpiece that you wish to hold and b) because they are bored in-situ, you are assured of perfect centering.

I don't think that a "couple of bits of wood" are an adequate substitute somehow. We're not talking here about holding something in a vice......

sorry chap,i was thinking it was for holding in vice jaws

Christ how much vibration are you expecting? The part is less then 1/2D. plus a bit more for parting off. Its not going to be more than 25mm out of the chuck. SECO/Iscar/Sandvik/Kennametal etc all make plunge/turn inserts, so you wouldn't need a LH tool. Or if you want to keep it retro you could always grind you own HSS :shock:

Yes fella, that's what an old fart like me would be doing

 

[mikee]

you'd need a treadle lathe tho

That's what the first lathe that I ever used was (when I was about 10 years old) . My father had one that we later converted to electric motor drive (once we could have mains electricity.......).

He also had a wood turning lathe driven by belt from the rear wheel of a statically mounted bicycle - I put in many an hour driving that thing when I was a lad :roll: .
