lol, That was before my time on the forum. I did ask around if anyone had made something like that, when I was trying to figure it out. I can't remember who, but he had one in a cooler. I wanted mine smaller to fit in a compartment. The one I have on my boat doesn't look as good as the ones I make now. But it has been working fine for over a year now with no problems. A little tweek here and there, and volia!

I just looked at that thread after posting this. I registered the same month as your post, when I started guiding, but didn't hardly ever get on here for a long time.

answered your pm.

I received a Pm from a buddy today. He reminded me it was Fast Guy who had the thumper in the cooler. Lots of different ways to build one. Whatever works is good.
