no previous part Part 1 of Roubo Try Square series Part 2: Pegged and finished »

I’ve been working on building a Roubo try square that was in an article by Christopher Schwarz. I saw the layout square in the new magazine and it referenced this one. I went ahead and picked up the plans which helped a bunch on a few of the details. Here is the progress so far. The material is cherry, 3/4” handle, 1/4” blade resawn with my diston rip saw. Everything was done with hand tools and all that is left is to make some dowels with my homemade doweling plate and peg the joint, then finish the wood. It was a pretty quick project and was easy to get square with a little tweaking after glue up.

I wonder how the weather/humidity will affect the accuracy of the square.
Beautiful work

Good work – I have been thinking about doing this one also. I have in the past made a pair of winding sticks and straight edge from walnut. I did do one touch up on the winding sticks at one time but otherwise they have been stable so I expect that, while you may have to double check the accuracy of the square periodically, this should work fine. It did for several hundred years.

All the best!

Forgot to mention the size, the blade is 15 inches long and about 2 1/2” wide, the handle is 10” long and 1 5/8 wide. I have also been drawing up a smaller one, I’d like to have a 8” and a 4 or 5” model for smaller work too. I think I’ll try a oil/varnish blend for the finish but not sure yet. Thanks for the comments.

I’m more in the market for a 2” model. I like the idea of making it out of wood though.

Nice job. Looks like very exact joinery for hand tools. Well done!.

Also liked the smaller one by 3fingerpat.

Is there a purpose for the shaped ends?

Gofor,

I don’t have a purpose for the ends other than I liked the way they looked. I just copied it, maybe Andre Roubo had a plan for them but I don’t know what it was. Getting the joinery tight was easy, I cut the mortise and then used a smoothing plane on the blade to slowly sneak up on the right thickness. I don’t know how I would have done this with power tools. Guess it is what you learn and get used to.

Thanks,
Mike
