Easy to Make Diagonal Measuring Jig

I make a lot of my Super Easy Workbenches to sell on Craigslist and squaring the 8’ ones is an absolute PAIN because the tape keeps moving off the corner of the frame.

I asked myself, why am I doing this the hard way?

It’s been the best ten minutes of work I’ve done in a long time. It’s saved me a ton of time and helped me make some nice coin in the process!

not sure I get this
why not cut off the outside corner off the jig so the tape so you can rest the tape on it on the 45 degree angle… and a specific distance away from the inside corner of the jig

I just do not get it using the nail as a reference and I am sorry I am not the kind of person so say something is great when it seems logically flawed from the current info I gathered here

so I do not have any friends here but I ask the questions everyone else wanted but were afraid to ask

Nice idea!

In my thinking, a block with 45 degree cut would limit you to squaring up…well…only square shaped construction, no rectangle ones.

The point of the jig is so that the tape has a consistent pivot point (consistent measurements) and doesn’t slip off (pulling my hair out). Resting it on the corner of the wood can produced mixed results since the part of the hook that ropes the wood can vary in position hanging the measurement angle as well as slip off.

Having an offset by the nail is no issue because the offset is identical since you move the jig to the other corner for the measurement. No different than those who measure with a rule starting at 1 instead of the edge. Since we need equal measurements to get it square, the offset is ignored.

I use a giant 12” framing square when I drive the first screw in each corner. That usually gets it within 1/8” of being square but crappy Lowes wood can really make squareness all to being relative.

Neat concept, the pivot does the trick! I’ll have to have one of these.

Hey Jeff:

Nice little Squaring up Jig. I had a look at your Website (Very Well Done. By The Way) and your “Super Easy Workbench”.

Yes they are ….LOL…. I made one about 5 Months ago mainly to get the DP & Bandsaw off of my Main Bench.

Also lower shelf for larger Tool Storage. Only difference between yours and mine is I used 1/2” Stove Bolts to hold it all together so I can raise or lower the bottom shelf if needed or take the entire thing apart (Portable) which I doubt I will ever do. 2-2’x4’ Handy Panels and 6 or 8 pcs of Spruce 8’x2”x4.” from HD.

The only place I Glued was the Handy Panels to the Frames and just used 1” Ringed Flooring Underlay nails. That’s when I squared it all up.

Mine looks prettier than yours though …LOL.. Wanted to get rid of 1/2 can of Minwax Sedonna Red and an old can of semi, water based poly.

All together maybe One Day Total Labor. Money? CHEAP!

Don’t you just Love It when a Project goes together Nicely and Quickly! Especially off the top of your head, no plans.

I’ll tell you …. One of the best (Worthwhile) Projects I’ve ever built!

Regards: Rick

That’s an interesting choice of color for shop furniture! :)

The “Super Easy Workbench” is pretty flexible depending on the customer’s budget and needs. One person had a brake lathe they were using so I built the legs from 4×4 and used 3/8 hex bolts.

The server rack at work is one of the portable “dog kennel” types but it has close to 600# in it. Of course, another “Super Easy Workbench” was used here too except it’s 36” x 48” and uses 4×4 legs.

With a bit of ingenuity, that workbench design can easily be adapted and I make so many that’s why this jig became so useful to me so I decided to make a nicer version and share it. My old one was made from some junk wood and used a crooked nail. This one is much nicer and a lot more accurate!

Have your say...
