Rob Cosman's Mortise Gauge Attachment
My mortise gauge attachment easily fits into the body of my Rob Cosman Marking Gauge and you instantly have a mortising gauge. The attachment also fits my "Cosmanized" Woodriver Marking Gauge and any other marking gauge with a 5/16" inch hole. The attachment comes with:
1/8" hex wrench to remove the cutter head for sharpening.
A brass knurled locking handle
An O-1 hardened cutter.
Save yourself money and set-up time and purchase one of my Marking Gauges and the attachment as a Kit. Click on the "Kits" tab on this page
