The digital readout option for this sander is made by Wixey (PN 71938-DRO) and costs $106. I see that Wixey also sells a Digital Planner Thickness Readout (WR 510 Tyoe 2) for $57. Both of these come with mounting hardware.

Just wondering what the differences are and if anyone has installed the less expensive option, and if so, how it is working for them?

I have the cheaper readout and it only steps by .005” I thought it would be an issue but it isn’t. Calibrate by planing something, throw a micrometer on it and set the Wixey indicator to match. It mounted with ease and the slanted display is much easier to read than bending down to get the old sight line level – not to mention wayyy more precise.

You tell me.

I also have the Wixey 510 (mine’s a type 1) on my planer, and it’s really is quite accurate. I don’t have any pictures of it like Mark’s, but I pretty much get the same results.

Can’t tell you what, if any, differences there are between the two… but I can state without doubt that any time you purchase a part from the manufacturer (or aftermarket supplier) that is specific to a machine, you will typically pay significantly more for it. For example, the lower bearings for an older Delta bandsaw, from Delta, costs $42 a piece. From an aftermarket supplier like, they cost $48. Yet those are fairly standard 87504 bearings that can be purchased from a bearing supplier (like Accurate) for $12 (I have the invoice sitting in front of me :).

While the labeling on that DRO is slightly different between the two, my guess is that they are functionally the same and you are paying extra for the manufacturers blessing when purchased from them (or amazon or wherever it’s being sold for a specific machine). But that’s just a guess based on what I’ve experienced over the years.

They charge extra for the two 1/8” / 3mm mtg holes you drill when you don’t want to use the double stick tape (you don’t want to use the tape).
