Marking Gauge Block in marking/panel gauge mode
The marking gauge block can be used as a normal marking gauge using the clamping plate to keep the beam in position.
The beam is 20mm wide to fit in the slot and 21mm high so that the clamping plate grips it.
In this example the gauge beam holds a hardened nail and a pencil.
When used as a panel gauge remove the bar bolted to the base of the block so that the block runs on the rebate when using the 20mm slot.
You can use varous beam widths by adjusting the length of the clamping plate bolts.
You can use your tooley park scriber for fine adjustment or simply fix a pencil into the end of the beam and adjust stick out using the clamping plate on the block.
You can draw a line parallel to a curved edge using bearings which bolt to the base of the block.
You can also bolt or screw on auxillary fences to the block for different applications.
The aluminium beam doesn’t fit in the 20mm slot so if you wish to use the bearings with the versatility of the aluminium beam you can make a 20mm wooden beam with the end reduced to 19mm. The aluminium beam can then be bolted to the wooden beam.
