The white residue is also the result of the fumes reacting to the amino acids in your body oil. Super glue fuming is a well accepted method of developing fingerprints.
I usually put the silicone on first so that when you turn the jig upright the silicone is on the outside. This shows the most color. I use the silicone as an accent color. I don't believe that it inhibits the movement of the rubber too much.
Black Pearl is what they call them before they changed to Black Platinum. They are the same thing. Gamakatsu makes a 60 degree flat eye, but it is pretty shiny.
I tried the hand crank meat grinder and maybe mine was too small, but it was a chore to use. I then got an electric grinder from Harbor Freight and I'm very happy with it.
In the early eighties I was making jigs for this particular customer who wanted a specific set-up. I would take a Daichi wide gap fly hook, heat it and put a 90 degree bent in it to form an eye leg. Then I would mold them into a little 1/4 oz. Arky head. I must have made over 500 of those things without a single failure. Maybe I got lucky and maybe not. The customer was a tournament fisherman and used to give me regular feedback on all my products. Back then we just did stuff.
I recently purchased a pair of 6 in. Craftsman narrow jaw locking pliers. I use them almost daily to bend wire. I noticed that they were loosing their setting and slowly opening as I used them. As I was taking a closer look at them I noticed that they had "CRAFTSMAN" stamped on one side and "CHINA" stamped on the other side. You can't imagine my disappointment as I was under the impression that Craftsman tools were made in the USA. I guess you learn something every day.
Since they are plastic you can rig them up and test them without fear of water logging. That way you can paint the good ones and maybe return the rest or exchange them.
What are you using now? If it has been working for you all this time, why change? I have tied only a few Bucktails, but plan on increasing production. I used the same Nylon Upholstery Thread that I use on my jigs.
