Although I have seen a couple of posts on DIY SlideTrax hardware, I decided to document a more complete build process that would show the start-to-finish steps including part numbers, pictures, etc. Depending on how many accessory plates you want to build, this can save a lot of money and the method works great. Besides, I just like to build stuff :)
If you don't want to fabricate your own SlideTrax nuts, you can pick up a four pack online at Hook1 and a few other places (I didn't see them on the Harmony online store, but I may have missed them). The rest of the DIY build components will work just fine with these plates. Since I had the aluminum stock and cutting board left over from my rear transducer arm build, the cost to do this project was super cheap. I plan to make a few more different accessory plates with all the stuff that I still have left over.
Here are a few preview shots and the full how-to write up is on my personal Palmetto Kayak Fishing Blog HERE.
