Do you want to be the guy with a four inch johnson??? March 23, 2008

Sorry for the title, but remember it does extend out to 7 inches...hah!

Sure there are other ways of doing this same job, and I've always done it by using my more expensive calipers, but that's more tool than you need. You can also just saw a notch in a board the right size if you're doing repeat measurements.

But this little plastic tool is handy, takes up no space and is quick to set to any dimension. Example, I rip boards to support steps and deck planking and have to set these back the thickness of the 5/4 board that will sit on it. Ripping long boards often results in a curved piece that you have to screw in place and measure at each screw for accuracy. This little 4" Johnson makes that easy, and you just slip it into your shirt pocket when you're done with it.

Good tool, great price!

limited use February 6, 2008

This gadget is of limited use. A good old tri square is quicker and fills the hand better. The one advantage of this one is the size that allows one to put it in one's pocket.

this is great to have something in your pocket to gauge your depth on something to transfer it to a saw for accurate cutting. Easy to use and tighten down accurately.

This item is great. I use it for checking the height of my table saw for dados, router bit heights, stop blocks, etc. If you are a trim carpenter or woodworker it should be in your toolbox. Perfect stocking stuffer or birthday gift.
