Every so often I get the question about hollowing rods and how I do it. I use a Curt Elder Hollowing Mill. Curt came up with this about 7 years ago and sold a few while he was building rods. The one difference between his and mine is I have set depth controls for butt sections and tip sections. Curt's mill had an external adjustment and depth gauge that you set the mill to. I hollow to certain depths for butt sections and a different depth for tip sections.
I am currently working on a prototype of a 8 wt 8'6" rod with composite ferrules. The blank weight is 3.2 oz. However, with extra cork and a bigger reel seat I am not sure where its going to end up. I hope to have a pic by next weekend of the rod. The taper is based off a parabolic style so I am excited to see how it turns out.
I will be attending Mike Clark's get together the first weekend of August. I hope to have several rods for people to cast.
