I received a link to this video tip in an email from FineWoodworking today – here is the link

I have a set of brass setup bars that I use frequently but never gave a thought to these keys that are available at most hardware stores.

Here is an excerpt from the web page:

When checking the depth of a dado or preparing your bandsaw fence for resawing, using a tape measure or metal scale can be clumsy at best. For less than $10 however, you can outfit yourself with an entire set of incredibly precise measurement tools that fit in the palm of your hand.

Keyway keys, more common to the machine shop than the workshop, are manufactured to extremely tight tolerances and are an easy way to verify the accuracy of a variety of common measurements.”

I saw the video on this website and added the keyway keys to my list for my next trip to my local hardware store. I alredy own the measuring bar set from Oak-Park, but the kit has only 5 bars. There’s always room for more, as they say. Note that I also use my twist drill bits for setups, but many times you need square gauges.

As Gary Rogowski once said “Joinery is patience and accuracy”. For accuracy the measuring bars are excellent.

More to come for sure in my shop.

Great idea. So is the “drill bit” idea. Hadn’t thought of something like this and Dad used to be a machinest! (I am ashamed)

Thanks for the tip.
