Overview of the BB Scriber

 

The BB Scriber and the UBB Scriber are both the same size. 

Bigger than the FB and SB Scribers but a size down from the JUBB Scriber.

 

 

 

This image shows the BB Scriber working with a metal scribe using the front lip as a guide.

It has the same footprint as the FB Scriber (64mm x 25.4mm), but is taller (53mm).

 

 

The marking tool can be held above or below the pivot point giving you more options for the angle the marking tool is presented to the work piece. 

To change from the over to under positions  remove the pivot bolt and flip the body 180 degrees. 

Re position the threaded dowel and insert the brass spacer before the thumbscrew (or store it in the hole provided in the body if it’s not needed).

In this image the BB Scriber on the left is holding a pencil above the pivot point.The BB Scriber on the right is holding a metal scribe below the pivot point.

Both the UBB and BB Scribers have extra holes allowing the body to be mounted further up the aluminium cradle increasing the span of the scriber from 1mm to a maximum of 90mm with a pencil and 75mm with the marking wheel holder.
