I have what I think might be a new idea. I recently bought the powerjelq device with the extra set of rollers. Personally, I do not think that it is as good as manual jelquing. But that is another issue. In the beginning of my personal endeavor I tried to make my own device using the wooden dowel that was described in the PE archives. I covered the dowel with flexible tubing for cushion as suggested, but it still hurt. Knowing that the PJ device had nice cushions on its rollers, I slide them off and onto the dowel. Unbelievable results. The only downside to this technique when jelquing is the difficulty in really getting to the base as my fingers get in the way.
Everyone has contributed so much to this forum, I thought that I would try to add something, even though I am a newbie.
