My version of this handy tool is made of 18mm Finnish-birch plywood [one of of my favorite materials] and can handle up to 75mm stock. The design is minimalistic in approach. With rounded corner on the sliding bar that cradles the thumb when the bar is pushed against the wood for a close fit. A large screw is inserted at the rear end for fine adjustment.

Very nice! I do favor the functional almost Scandinavian look to it. Question: isn’t the screw used to adjust to thickness of the saw blade?

Looks like he built the kerf into the design.

That looks sharp. How does the screw adjust? Welcome to LumberJocks!

I don’t understand how this one works. How do you adjust for kerf?
What does the screw adjust?

I’d like to know the function, too. I’ve never seen one of those before. Whatever it is, it looks really, really nice. Good job on whatever it is.

favorited… loving it. I was thinking a while ago on building on of these and yours surely look like what I wanted to do but, i think, I am not able to do so cleanly.

Nice work!

inspired on this one? http://www.youtube.com/watch?v=PQ6_S6lZKLI

works like that, isn’t it? (Just that the kerf if fixed..?).

Ah-haaa! Thanks for the link, ediazf. Now I get it, but I don’t think I would have figured it out just from the pictures. I can be pretty dense on days that end in the word “day.”

I think that he uses the phillips screw on the end to increase/decrease the kerf by screwing it in or out. Or at least that is my take on it.

StudioFormaat that is a nicely done tool and your photography is stellar!

I think that the kerf is already set when the end of the jig is flush (I think you can see that there is a kerf like space on the inside part where the two pieces meet). All you have to do then is to place the wood piece on the slot and you have the correct spacing for your second cut….

That what I am thinking… is too late here (Chile, south america) for my brain to function well.. I am giving it another thought tomorrow and maybe even try to build one for myself :)
