Re: Shopmade Marking Gauges?

>The gage that gets the most use in my shop, by a long country mile, and I have a variety from home made to a mortise cutitng gage from Bridge city, is the one blade japanese style with the screw adjust. This is an easy model to make. I made one for my dad using a wedge, and as comited as I am to such stuff as wooden planes with wedged blades, I have to say the screw has jumped into my hand more often. I thik the reason for that is that with gages one may want to move in either direction with great accuracy and/or speed. This would be a rare circumstance with a plane blade.
FWW did an article on making a wedged version a few years back. There were a few tweaks to the look, that dated like a GMC Gremlin. The one I use most faithfully seems to have a wedge shaped blade made out of a tweaked piece of cold rolled metal. It still works really well after more than 20 years, though the adjuster is a little galled. High quality baldes are offered at modest prices from Japan woodworker.
The main appeals of this design are the size and shape of the fence. NOt to big or too small, much better reference surface; Any blade seems more generally useful than a pin; the adjuster is crude but it has just the right characteristics. The beam locks up without a wobble, it can be accurately moved the slightest amount (I often use a digital indicator to pick stuff off plans so I need one that can slide in and pick up a thou.
Within this class of tool there are beam versions, cutting versions, mortice version. A well developed range. Though I use the single blade one out of all proportion to the rest.
