It may not work on something as small as maybe down to 6mm or something, but any other size circle it's perfect.
 
Get yourself a piece of paper+compass, get the diameter of your circle , draw the circle on the paper, then cut it out nice and accurate, fold it twice , you then have a perfect segment of the circle with a nice point, put that on the workpiece you want to find the center of, accurately lining it up, now where ever that point is will be spot on the center
 
Maybe most people already know this way.

We do,
but 5mm dia is a bit small for such methods, even more accurate is to draw the circle in a drafting program and draw the centre lines with the finest lines possible.

Yes you can do that Jim, OK for maybe just one off, but if you center punch more than a couple of times hole enlarges and I find accuracy disappears, I get what your saying though.

Thread: handwheel dial gauge

Thanks again for the replies and advice and also saving me quite a few quid.
 
I have put some pictures of the lathe I am restoring in my Photo Album, hope you can view them OK,
With regards my original information/advice request post, I honestly didn't think it would clean up so nice with a bit of elbow grease, I thought that they were too far gone, I haven't got a dedicated buffing machine, so I got my old drill out found a worn out wire wheel stuck it in the drill chuck and stuck the Drill in the vice on off I went , when all the rust was gone I got out the T cut and some fine wire wool gave it a good T cutting , then buffed it up, what a surprise that was, I really happy hoe they came out.
 
Thanks

Thank you all for your replies, it's most appreciated,
 
The Lathe dates from around mid 40s, I contacted tony at [email protected] he told me the lathe is a rare one, So that's what got me into restoring it, so I stripped down with the mind of getting it back to tip top condition, I know the history of the lathe, the chap I got it from own it for the best part of 40 years, all the time before that it was stuck in a shed and was own by the Bristol Bulldogs speedway team, in all that time it was used very little,
Going back to the Dial Gauge in the picture, I will see if I can clean/polish it up, there is one point on it that does have pitting that's obscures the number 50 and it's marker line. but all the rest will come up like new.
I will post up some pictures of the lathe in as far as I have got with the restoration, see what you all think of it, if that will be OK.
 
Thanks

Hello
 
I am restoring a Cromwell Mk2 Lathe ,I am about 3/4 way through so far, just starting on the Top slide and carriage strip down, after evaluating the the parts, all it seems is that I will need two new (dial gauges) if thats what their called,
