Design suggestion needed - simple plastic slider for small boat transducer
This shows the kayak transom http://i960.photobucket.com/albums/ae87/nickmdal/Bassyaks%20photos/IMG_4068Medium_zps318a10df.jpg
The transducer needs to be able to slide up 2 1/2", so that it won't get dinged when transporting the kayak. Therefore I want to attach it to something that I can slide up, but will remain attached to the transom.
Envision something like a paint stir-er flat against the transom in a vertical orientation. From above, I can grab the top and pull up to raise the transducer.
I am imagining the transducer's "holder" to be some sort of rail/guide combo that is friction and not wheel based. I found these items, but nothing any more useful.
Other thoughts were drawer center rail siders, tie/belt sliders (a hacked one). That and the pic above are all I could think of. Any suggestions would be so appreciated.
