Vertical height gauge

I'm thinking it should be more like this one:

Though the images that I found on Google mentioned earlier and Micheal's link show them all with straight scribes

Michael the vernier is adjustable ,but the vernier plate held in place by the two screws is tight in the apeture and is not adjustable.My height gauge is exactly like the catalogue .With the blade below the arm tight to the base the blade is 25/32" from the surface plate and the vernier scale is .150"above the 1" mark.

Evidently, I misunderstood your previous comment.

Bricky, how tall is your scribing blade?

Any chance of posting a photo even if just into your album or PM me if you can't upload and I'll give you my e-mail

Jason the blade is .360".I have managed to create an album so this might help to understand what I'm talking about.

I forgot to mention the slot at the front of the box the existing blade will not enter the slot and my neighbour who is a retired toolroom fitter thinks it could house a depth gauge that would attach to the arm?

Assuming that the height of 1.375 dimension is with the scriber clamped on top of the arm, with the inclined face uppermost:

The scriber, presumably could be clamped below the arm, again with the incline uppermost. This ought to move the scribing point down by (Thickness of arm + thickness of scriber) to reduce the height.

Otherwise you can use a bit of gauge plate to make a scriber cranked to such a depth that when "1.000" is indicated, the cutting edge of the scriber rests on the surface table.

If you are a glutton for punishment, why not make the cranked scriber in two parts so that the blade can be screw adjusted. Then coat the screw with an anaerobic and adjust it so that the scriber contacts the surface plate at the "1.000" setting. Once cured, you merely have make an allowance for the scale reading 1.000 in what is now the Zero position.

You can have hours of frustration trying to get it right!
