I was watching a River Monsters video and noticed the rod holders that Jeremy Wade was using. It was kind of hard to see them clearly. It looked like they were made out of 1/2" round steel bar and two pieces of 2" diameter steel tubing. I have been thinking about making some of these myself. I will be building them out of 1/2" diameter-36" long rebar and 2" diameter-1/8" wall DOM steel tubing, with a triangle shaped piece of steel welded to the lower end of the bar, to keep the bar from turning or pulling out of the ground. I know that, they will be very heavy but they should work well at the Ohio River. I will be hammering them into a gravel bar. It is pretty hard to try and place a rod holder into the ground here, due to all of the large rocks beneath the surface. I am not sure exactly of the tubing placement yet. I am thinking on making it about 18" from the top of the top cup, to the bottom of the bottom cup. The bottom cup will be 3" or 4" long with a strap across the bottom, to keep the rod handle from sliding through. The top cup will be 1 1/2" or 2" and have a slot cut in it, in order for it to be bent open, to accept the rod handle. This way I can bend it in and tighten it up, to better hold the rod handle and keep it from falling out. This will make it easier to retrieve the rod from the holder, without raising the rod all the way up out of the holder. I know that my explanation is very poor but it will make better sense after you see them. In my defense, it is late and I am pretty tired. If he can use these for Wels catfish, they should work really well for Flathead. If anyone has photos of the rod holders that Jeremy Wade uses on his show, please post them for me. Thanks in advance.
