I knew I had a few marking gauges squirreled away around the shop. I do have an excuse. I've never found the "perfect" marking gauge, one that will do everything well. Problem is most do not do anything well. I know it is a poor workman that blames his tools, that Lee Trevino hustled golf playing with a Coke bottle, but bottom line many marking gauges will not properly lock the stem in place.
Enough rant, here is a photo of the marking gauges I found while moving shop fixtures around. BTW, the reason for moving shop fixtures is to make room for the Plano Vertical Clamping fixture that should be here today or tomorrow.
I counted just under thirty, the ones I use are towards the rear with the exception of the Hamilton gauge. For some reason it is too much of a tweener, the Tite-Mark or the Kinshiro works better x-grain and the Marples combination is better with grain. The Philly is another that should get more love but doesn't, I'm not sure why that is other than it is big and heavy.
What can I say other than there are a few extras when I need them.
