To get the action out of a senko type bait it must be soft and pliable . Soft baits by nature are not durable . Most Saltwater plastic baits are made from stiff "Saltwater" blend plastisol to withstand the wear and tear from Salt water fish . Don't know if what you're trying accomplish is feasible ?

If Senko's came with an "ingredients" label attached salt would be the first ingredient .

Green hi- lite powder , Fine gold hologram glitter , Medium black glitter . If you're pouring baits loaded with salt (like Yamamoto ) this will lighten the finished color but if not maybe a touch of white pearl hi- lite powder or a drop or 2 white liquid color should do the trick . I have wasted a lot of plastic trying to match colors before I started testing mixing up color variations using clear cooking oil . You can get the desired color very close using the oil then fine tune the recipe using plastisol .

That hook point sucks but the skirt on that jig looks great !

You can move lead ballast around mounted externally outside the body of a prototype to get an idea how much weight you need and where to place it first for a particular design . Once you arrive at the weight required and drill into the lure body you will be losing a slight amount of buoyancy and slightly altering the center of gravity you had previously established with the weight on the outside and may have to make slight adjustments . I have taken a drill and slowly removed lead from a weight I had glued in for ballast after testing to get the balance back after moving the ballast inside the body . Not the scientific answer you were looking for but that's how I have done it …….

The one I had years ago did pivot here's a picture from ebay showing the wire construction .

A little tip on something I've been doing that works really well for a bait keeper . I take a single staple for a staple gun and using nylon thread ( rod guide , jig tying thread, or upholstry ) and tightly wrap the staple onto the hook shank and finish with a whip knot in whatever location you want on the hook . The leg(s) of the staple will be sticking straight out from the hook shank . I then bend them forward towards the line tie at a 45 deg angle and clip them off to about 1/8" long barbs using dikes . Now coat the thread with super glue and you have a simple and strong keeper. You can use a whole staple for 2 barb keepers or cut the staple in half (before tying) for a single barb keeper . I use thinner lighter gauge staples for finesse type baits with lighter hooks .

I have done a bunch of experimenting trying to match colors . Instead of wasting plastic during this process I switched to using an ounce of vegetable oil to see how many drops of what color{s} it takes to achieve the result I was after. You then just multiply the amount of drops by how many ounces of plastic you'll be pouring . I 've thrown out a bunch of colored oil in the process but it's a lot cheaper than plastisol .

I think it was like a 6 or a 7 but it was definitely the biggest willow blade available at the time . I think the big blade thing exploded on the scene in the early 80's . I don't remember Roland being the originator of the bait but rather a younger unknown angler from the East discovered it .

Are these beads glass or plastic ? If so you can definitely find them online searching sites that sell beads for jewelry making .

Great topic and video ! Instead of cutting a sprue afterwards a worm weight works great for a sprue shape . Drill a small hole in the master jig head just big enough for a short piece of spinnerbait arm wire . Put the wire in the hole you drilled and slide the worm weight onto the wire up against the master . Check alignment to make sure it's straight for a clean parting line .

These are old school type plastic baits that shine when the water is cold . Hard to find these type lures and color selection is not too appealing when you do but I don't have to worry about that anymore …..
