I needed an adjustable scriber that could conveniently work down close to the top of the surface plate. This design is infinitely adjustable and rock steady when locked. Adjustments are made by loosening the lock screw and turning the cylindrical piece that carries the scriber point made from drill rod.

The device disassembled... The slot turned in the cylindrical carrier serves two purposes. It prevents the cylinder from falling out when the lock screw is loosened and also prevents burrs raised by the lockscrew from restricting the adjustment of the height of the scriber.

VERY nice, and much simpler than GHT's device. My first thought was restricted range. Then I realized there's no reason an offset arm with scriber point couldn't swap in just the same as Thomas did. I like it, I like it.

Don't you love brass? It's nice to machine and looks great when you're done. I always try to throw in a little brass here or there on a piece of tooling if only because it loks great.

If only it wasn't so darned expensive!

Best,

If you put the scriber in the center, and use one of your computer programs to generate an eccentric........

No like it just as is. :)

No eccentrics, but one could engrave an angular scale and then use the computer to calibrate that scale in terms of height of the scriber.

I only remember using this tool once after the job for which it was originally built so I doubt any further refinements are forthcoming.

Marv,

Very nice work as usual with you. A dumb question if I may? What locks the scriber itself in place? Is the only adjustment in a circular motion?

Just wondering and hoping my spelling is ok,,,,,, :D

A setscrew holds the scriber in place. I'm not sure what your "only adjustment" question means. The scriber carrier is free to rotate 360 degrees.

Ooh, I like this design. I have a LOT of vintage phonograph needles that make great scriber points. Looks like I'll be making one or two of these holders. . .
