Vernier caliper spares

[damianParticipant @damiannoble34800]

Hi all,

I have what look to be a set of moore and wright 600mm vernier calipers which are missing the small gib/friction strips in the main body and the fine adjustment body.

I will try to upload some photos

Does anyone know where I can get spares

Thanks

Try Moore & Wright. Robert Butler

Those gib strips are made from brass or bronze commonly. If you can measure the gap and then buy some brass which is slightly thinner , you can make them yourself. The adjuster screws will all have flat bases except one which will be pointed, or smaller diameter. The odd screw fits in a slot cut about half the thickness of the gib, probably at one end or the other. This stops the gib from falling out.

I have tried. Seems to be very difficult to actually get in touch with them. Most numbers are sales only.

This was my second thought. My mitutoyo verniers are very similar and seem to use a piece of spring steel with a retaining peg hole which seems to be the case with the missing gibs.

I will try to raise a line of enquiry with M&W again before resorting to making some.

Presumably sales will be able to sell parts if they are still available? Robert Butler

Thanks old Mart. Never thought but checked the other smaller mitutoyo vernier and you're spot on.

Had some brass shim stock needed to be 1.25mm so adjusted it to suit. The width was 6mm and is held in place by a dog point grub screw on both sections with a 2mm end.

Fitted and adjusted it's now working like new.

Thanks for the help guys
