Bet you can't say it three times fast.

Looks nice Dave.

Simple, beautiful and fast to use. Is it made of some special sort of wood? The nice springy part must need the material to be hard but flexible. The same principle is used in the Aalto chair legs: sawn into slots to make bending possible

Glad you like it.

Anssi, I don't think the wood for the clamp needs to be anything too special. I seen them made of boxwood and maple; two woods on opposite ends of the hardness scale. The springy part of the lower jaw doesn't actually have to move too far.

Dave,
Very cool. Been meaning to make me some of those but always something else going on in the shop, or else shop time gets severely limited by stuff like holidays.

Or else some other tool making project takes precedent. Right now I'm making some French Style marking gauges that use a sliding captured wedge to lock the arm in place rather that some sort of screw etc. Popular Woodworking had plans for one a while back and I've made a SU model to work from. If I remember I'll post it tonight when I get home.

Thank you Jerry.

Funny. I just made a marking gauge last Sunday for my brother. I didn't know it was a French one. He'll be even more impressed.

Birdseye maple, walnut, cherry.

Here's a model I did almost a year ago, but which I've never built.

It's fun to go back to old models and re-do them based on your new knowledge. I got this one down from 220k to 57k and it only took me about half an hour where I probably spent a couple of days on the original.

Well, lets try this again. With the holidays and visitors from out of town time just went flying by with none left for cruising the www, so I'm just now getting around to posting my captured wedge French Marking Gauge. Managed to complete a real one in mesquite and ship it off as a gift to a young woodworker on a woodworking forum, and he was nice enough to take the time to provide me with a photo.

Here's the still from the skippy.

And here is the pic of the one in the real world.

And last, but not least, the skippy: http://www.sawdustersplace.com/Sketchup%20files/MarkingGauge.skp

I provided the recipient of the gift one with a total of four rails and a second pin for three of them. He'll use 3 of his mortice chisels to mark the location for the second pin in three of the rails and there-by have dedicated mortice gauges for each of them.

Jerry, that's great! What did you use for the pin?

Sawduster · 11 Jan 2008, 17:28

I used some 1/8" diameter mild steel rod from Home Depot. I had to get that one done in a hurry, so no time to order any high carbon steel online. Seems to work ok, so I'll use up the rest of it before order drill rod or something else.
