It was me, but what I did was adapt a blending block to work for hand-pouring duel colors by using two presto pots... This whole post is really starting to intrigue me... I have always been looking at the Jacob's press, but was never ready to buy one because it does NOT have the dual color capability... I have also always been intrigued by Bear's Bench Top Injection Machine, but I have been waiting to solidify my customer base before buying one because of the price... Hand injectors make nice looking baits, but the amount of scrap the injector's produce from the "plug" inside them as you inject is terrible!!! I am anxious for a product that the only scrap it produces is from the runners and the occasional bad bait...
