Really Silly Question – rpm facing off large diameters

Bandersnatch: I apologise for mis-interpreting your post, sorry. I'll go and stand in the corner with the 'D' hat on.

Thanks for all the responses, it's been far more of an eye opener than anticipated, I didn't think it would be such a wide topic for discussion. As seems to be a recurring case, a compromise between ideal practice and machine limitations, mixed with a good dose of operator adjustments on the fly seems to be the answer.

I've learnt about "Whittaker's Ring" which is interesting and also got an insight in to other peoples approach which is useful and will certainly help guide me.

Could anyone post of picture of the ideal "Whittaker's Ring" just for reference/education? – I say "ideal" its obviously more of an anomaly perhaps than an ideal?

Thanks again to all involved for sharing your experience.

How about including it in the list of smileys then?

Andrew I did not think you had any spare corners that were not filled with machines, tooling or castings

There is one small corner still available, currently containing the central heating boiler and chimney stack.

However, the boiler is being replaced next week, since it is over 30 years old, by a wall mounted unit. That means the chimney is redundant, so that will be coming down too. That will free up some floor space. Although it is already earmarked for the Clarkson T&C grinder that got displaced by the repetition lathe, and possibly my larger offhand grinder. I also plan to fit a small sink, so I don't have to mess up the main bathroom with mucky paws.

Regards,

Andrew
