I’m sure you’ve all seen those commercially made assembly squares. Most likely from R.
Anyheaux , years a go when I first saw them and they had a super sale, I ended up getting a pair. Of course I never needed to use them but they were there just in case.

Now I’m about to do a major large project and will need at least 10 of these and I was tempted to go and buy a few when the old guilt sit in and I had to remind myself that as a woodworker, If I couldn’t glue and screw two pieces of wood together to make a perfect 90 degree angle, I have no business calling my self a woodworker and owning tools.

So, looking around the shop in the good old scrap bin, I grabbed everything I could find and started cutting with my super obsessively accurate panel sled. That gave me perfect 90-degree cuts to begin with.

And I used 5 minute epoxy for the initial glue ups since I don’t have any patience and living in Houston I didn’t want to spend any more time in the garage than necessary in this heat and humidity. However, just in case the glue skewed things up a little, I ran few of them through the sled to fine tune them back to 90 degree again. And now every one of these squares is 100% accurate. Heck if you measure the ones you buy at you know where some are off by 0.1 degree.
This is the quickest way of making these.
you can never have enough home made Assembly Squares :-)

Nice work. Been meaning to make some of these myself, never seem to get around to it. Handy on glue ups, keeping cases square, good idea and forethought on your part.

THX All.
well few ways to make these but this is the simplest way.
other way is to glue mdf of ply together for thickness and then to cut them. that way is way too much work.

I will be using these on a large cabinet project along with kreg Jig which I’ve had for long time but the thought of using screws on a nice woodworking project makes me cringe.
Not sure what I will do yet but just in case I decided to use pocket hole, I will need these.even if I go with dado, these will help with glue-up and brads.

So far I’ve made 7 of these and that’s saving of 90 dollars not including shipping or taxes.
will be making few more just for fun of it :-)

They look great. Hows about sending me that super obsessively perfect crosscut sled?

If I had a super obsessively perfect crosscut sled, it would be 10 times heavier and heck you could have it since I can barely handle my super obsessively accurate panel sled.but you can make one as accurate as mine. not a rocket science. but if you want 0.001 or better accuracy then I don’t recommend wooden fence.

Very nice! Haha, I guess you can call yourself a true woodworker now! ;)

I live in Houston too…that’s why I tend to work in my garage with the door closed on most days unfortunately…..
