Here is the original patent, which you can view & download: **LINK**

Admittedly the helix is shown as a formed wire [whereas yours is a machined groove] but the operating principle is illustrated and described quite well.

Very many thanks for that; should keep me occupied for the next few days. From a quick read it looks as if mine is missing some sort of friction element to make the direction setting lever to stay where it's moved to.

No wonder patent agents charge a lot!

If anyone has had one repaired by Verdict? Could you give an example of the cost of repair please, Of course each case will be different . But any examples would be helpful. Probably to all interested parties here.

Hi All,

As far as I am aware Verdict no longer support repairs to their older products. Happy to be proved wrong though!

I did try once and was turned away. I am also pretty sure that the cost would be prohibitive.

I have used MITUTOYO a couple of times to repair various instruments and they always provide a written quote before proceeding which one must approve. The quality of their work is excellent as to be expected but again not cheap. They also stock a fairly large range of smaller spare parts if you fancy a bit of DIY!

There is an amazing US guy who makes dial gauges and DTi's etc come back like new but the postage and sometimes customs charge usually make it prohibitive again though I am looking nto getting 20 or so done at once.

Cheers, Martin

John 'Doubleboost' has a pal 'Bob' that revitalises / repairs DTI's, dial gauges, has over the past couple of weeks made some videos on repairing various DTI's as part of John's 'Sunday night nightcap' series on YouTube. Look on You Tube 'Doubleboost', latest video is # 243 iirc.

If my elderly Verdict, which has the formed wire helix, was sticking, I'd try a judicious squirt of very light lubricant before further dismantling.
