After surfacing a Douglas Fir slab using my 2 inch diameter surfacing bit, I decided that I needed to up my Z zero game. The problem is, my Amana RC-2255 surfacing bit is too big to fit into the top of the standard Avid 3-Way touch plate. So, I figured why not add a second touch plate into the mix? So, I reached out to @Eric here on the forum, and asked if such a thing were possible. Not only is it possible, it’s downright easy. He squared me right away with the parts and wiring diagram, and 15 minutes after receiving the parts, I had my second touch plate wired in and working. It was such a slick, painless addition, of course I had to make a video about it.
Avid doesn’t list the parts required for this modification in their online store, but if you contact them through the website, they can take care of you.
The parts you’ll need are:
A 4-Pin M12 cable (Male on one end, female on the other) the length of your choice.
A 4-Pin M12 Splitter (Single male to 2 female splitter.)
A 4-Pin M12 Male Field Wireable Straight Connector.
I also added a 5/8 inch diameter magnet for the ground wire, which I got from K&J Magnetics: K&J Magnetics: Standard Mounting Magnets
I also did a bit of digging and sourced the parts (other than the magnet) elsewhere for those who want to shop around. Those links are in the video description over on YouTube.
If I ever decide to venture into cutting aluminum (hey, I’m a wood guy) I’ll make myself a 1 inch thick touch plate, so I don’t have to remember to change the touch plate thickness every time I go to use the second touch plate.
Some may think it’s overkill, but I think it was worth it. It’s speeded up the work, and I now have much more consistent results.
