A flashback to a jig I made for my very first podcast in 2009. It’s similar to some jigs on the market.

Thanks again, I have been using this method ever since I saw your first video. I did change the screws to threaded rod sharpened to a point and screwed in using opposing nuts. At first I didn’t have a reliable square so I referenced both sides of the blade, when the measurements were identical then the blade was at 90 degrees and I could use this to check my existing squares.

The video in HD is soooo much better. Comparatively speaking it was like watching an old B&W Batman and a new one. Still a great jig especially in HD.
Thanks Brian!

But, on the other hand, there’s my Wixey angle gauge, which I use all the time and it hasn’t failed me yet.
It’s probably more expensive though.
The big plus is that it also gives me other angles beside 90ยบ.

@Don – This jig will allow you to measure other angles too. If you have a 45 degree angle block for example, you could zero the jig at 45. Then align the TS to 45.

Another option that requires more calibration, would be to get the plunger perfectly parallel to the table surface. Then you could measure any angle dependent upon the travel of your dial indicator. There is a cool trick to accomplish this that I might cover in another video.

Remember that Angle = ArcTan (D1 / D2)

D1 = distance measured by the dial indicator
D2 = distance between the plunger and bottom screw on center

So with more calibration this jig does everything a Wixey will do but requires that you make a calculation to get the angle.

Really cool jig. I’m starting to like my dial indicator more and more, but like Don said, the Wixey for me is much easier. The videos are really coming along – keep it up

Always fun to watch video, great idea I have used this because thx to you. I had to wait 90 seconds though because of blip advertising hope that wont be the norm.
