Mounting the Digi-Planer on a Woodmaster planer.

The following shows how I mounted a Digi-Planer to my Woodmaster 18" planer. You can click on any image for a larger picture.

It may not be obvious why I wanted a digital readout on my thickness planer but the reason is simple. It lets me accurately and very easily reproduce boards the same thickness as other boards in any given project. For example, when I do a project I try to thickness all the stock at the same time. If the thickness is a little off, it usually doesn't matter because they are all the same. Invariably, I will change my plans (or mess up) and have to go back and thickness additional boards. The Digi-Planer lets me do this so all my boards end up precisely at the right thickness.

Another reason I like the Digi-Planer is that I'm less prone to make a mistake reading a digital readout than a scale. This is why I also have a DigiFence.
 
Yet another reason I did this mod is that there is a huge parallax error when reading the scale as it comes (or mine came) from Woodmaster. These two pictures show two views of the same reading and they are 1/8" off. This problem could also been solved by either mounting another pointer between the scale and the red bracket, bending the bracket, or by removing the red bracket entirely.
Here are a couple of pictures of the end result, showing the Digi-Planer mounted on the Woodmaster. It's a little hard to see but the Digi-Planer is simply bolted to the Woodmaster right above the feed control and then bolted in place of the red scale pointer with the bracket described below. The top of the Digi-Planer is not bolted to anything. The good thing about this is that the digital scale is low enough that it doesn't get in the way of taking the woodmaster cover on/off. The bad thing is that the display is rather low (the height of the feed bed) so you have to bend a bit to read it. Of course, that's also the same problem with the stock scale.
The Digi-Planer comes with an assortment of brackets and screws. I was able to do do the mounting with what was supplied plus one extra screw.
Here are the two brackets I used to make a single offset 'U' shape bracket.
Here are the two brackets bolted together. Note how washers were used as spacers.
Drill out the rivets holding the red pointer, and tap the holes for the bracket. Then screw the bracket in but don't tighten.
Drill a hole right above the Woodmaster feed control so that you can bold on the bottom of the Digi-Planer. Make sure that the Digi-Planer is vertical.
Now you can check that you have the right number of spacers. You want the Digi-Planer to travel straight up and parallel to the Woodmaster height adjustment screw.
Tighten the screws, double check that the Digi-Planer travels straight and parallel to the Woodmaster height adjust screw and you are good to go.
NOTE: THE NUMBERS ON THE ANALOG TAPE MEASURE OF THE DIGI-PLANER READ FROM 0 TO 8 FROM THE BOTTOM-UP. IN THIS INSTALLATION, THE ANALOG TAPE SHOULD BE IGNORED.

NOTE: THE NUMBERS SHOWN ON THE DIGITAL READOUT WILL READ NEGATIVE NUMBERS INSTEAD OF POSITIVE NUMBERS. THE NEGATIVE SIGN CAN SAFELY BE IGNORED. IF THERE IS TOO MUCH OBJECTION TO THE NEGATIVE SIGN, A DIFFERENT PRODUCT SHOULD BE USED.
