Yes AdeV
That was my thinking as extended pointers are freely available, although I could make one.

Could you make an extension for the DI plunger? Might be the easiest fix...

He who's never made a mistake has never made anything !

. . . . it's all a learning exercise  :thumbup:

I have been getting used to using my new to me lathe , I had already made a mount so I can use the graver, and I thought next I would make a carriage stop but it needed to be a stop and a mount for the dial gauge well I was chuffed that what I had made was going to do the job until I fitted the dti  :doh: the carriage hits the mount before the full travel of the dti , so a slight modification is needed.

Phil, John - SALTER got left behind while I was moving it all to the middle of the page - thanks for pointing it out - I'd have been annoyed if I hadn't noticed it before I'd finished.

Phil, I could do something like yours - but I'm trying to make it fancy.  I have thought about doing a metric dial on the back of the imperial one.  Interestingly I found a picture of an original metric scale which was calibrated to 15 kilos (about 33 pounds) - I think they would just have adjusted the bar that goes through the spring to make the spring shorter.

Russ, the original was white paint on tin plate, with the design printed or stencilled on.

Andrew, that is a very good idea.  I had actually thought of that but dismissed it because I thought it would be difficult to get a printout without pinholes in the large white areas, but you prompted me to look again, and I discovered negative photoresist.  I've never done circuit boards like that - I generally use press'n'peel.  I will investigate further.

Hi Russ,
     Perhaps you simply missed the brand "SALTER" on the original brass face you put a scan of in you post?

I printed mine on card, cut round the outside, cut a bigger centre hole, encapsulated it and then trimmed around the outside and punched a centre hole so that it was completely sealed against moisture. I then stuck that to the old dial.

I wasn't bothered about it looking authentic - and I drew a scale calibrated in kgs.

Why have you missed out SALTER above HOUSEHOLD SCALE?

Think of it as a printed circuit board. Photo print it onto transparent sheet, apply photo-resist to a nice clean brass disk and expose it through the transparency.

Then etch the brass disc - you may want to make a negative version of your artwork.
