60 degree miter square

Everyone’s got a 45 degree miter square and probably a few 90 degree try squares, but I’ve got some projects in the queue that are going to need 60 degree angles, so I decided I needed to make a miter square.

O1 tool steel for the blade, treated with Birchwood Casey Plum Brown. Sapele for the body with a #7x15mm finger groove on both sides. Brass screws holding the two bits together, and some brass square tubing to protect the end-grain on the body. Assembled over the course of three mornings.

May you have the day you deserve!

That looks great Dave! I usually make a quick guide out of a piece of scrap plywood. 
Nice.  So my question is: how did you make sure that it is 60°?

--Nathan, TX. Hire the lazy man. He may not do as much work but that's because he will find a better way.

Nice!

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".

Dave, 

Nice 60 degree you made.  like the Sapele body wood.

Thanks, folks!

Nathan, I used it to make a mark at 60 degrees both ways from a straight edge, then laid it down and looked to see if the two lines (which should be 60 degrees apart) lined up with the sides of the square.

I also checked the 120 degree side against a hexagonal box I have. Everything was within a pencil-line thickness are 4 inches from the vertex, which is good enough for the work I'll be doing.

Dave, I bought a 8/4 x 8 x 6 foot board of sapele at the local lumber yard for far too much a couple years back. I've been taking small pieces off it (sometimes quarter sawn, sometimes rift-sawn) for tools for a couple years now. It's good looking stuff.

May you have the day you deserve!

Fancy miter square.  But is it a square if it is 60 deg? Either way, it looks great and it also looks like it will be very reliable.
I really like the look of this tool, looks like the tools of old, when tools were made to look beautiful & made with pride. 
`I think I see some diamond inlay work coming up.

Thanks, guys! Note that this square is similar construction to the ones I made for BigShooter in a swap back in 2021. Those were Khaya instead of sapele, but otherwise pretty much the same. I had even planned to make this 60°︎ version back then. Only took me three years to get to it.

May you have the day you deserve!

Sweet, great looking miter square. Just discovered this while first time looking in metal work, you're a man of many trades. 
i guess i missed this the first time. great looking square dave, now just a matter of putting to good use,

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.

Thanks, gents! And thanks for the second comment, Tom! One for each craft I checked!

The project that needs the 60 degree angles is still simmering, but I need to do many smaller glue-ups before I get to the point where I’m going to start cutting and gluing the 60 degree angles. Probably won’t see anything there until 2025.

May you have the day you deserve!
