Lathe work question and help

[milly]

I need to skim down the outside of my cylinder sleeve by 1 mm. I have been given access to a lathe and the barrel fits the chuck ok and turns without hitting anything.
The only thing that touches the cylinder as I traverse the tool back and forth will be the carriage.
My question is how far can I angle the cutting tool back towards the machine in hope to gain enough clearance or not as the case may be.
Thank you

Turn the compound perpendicular(or as close as you can)to the cylinder. Most are set at an angle. That should buy you some room. You can also extend the tool, just have to be careful of vibration or chatter.

Thank you gsx600racer, I set it up from what I remember from school. Last time I used one of these I was 13 now 62
Got a bit of chatter and I think health and safety would have spat out there denture's if they walked in. I was shown how to turn it on. Switch on at plug let the motor spin up and then dump the clutch and away I went, no safety cut out button, shield or goggles, did get a bit of chatter from the tool bit though but cylinder done and the mechanic can fit it tomorrow. I was going to give it to the local engineer but he away in India for 2 weeks.

I hope it fits OK. It looks like you needed to indicate the cylinder in before cutting to make the cut even.

I did say to the chap fitting it to give me a shout and I would take it down some more but instead he dremelled the cases with it all still in the scooter, changed the oil and advised I change oil again. Told me this after I paid him and was about to ride off. Next day changed oil, lots of Ali swarf in oil filter cap and the saucepan I drained it in looked like it had a metal flake coating when I had drained that. Next I put flushing oil in and drained that oil looked ok then. Hopefully nothing has been damaged by all the swarf pumping around. I won't be going back there again.

That's not very professional of them.

All that swarf has ruined the bearings.

Sorry I missed this back in Nov.

But for others...a 3 jaw chuck is for holding round "stock" close to center not on-center.

A 4 jaw chuck with soft jaws or soft shims to protect the finished bore is what is needed here, allows truing to center with a dial indicator. I have had good luck with a 1.5" boring bar to reach in near odd shaped spinning parts.

You did your best, it was probably good enough.... until the fitter hack got a hold of it.

Sorry to hear that.
