Do-it is pretty reliable and if you have any problems or concerns a phone call is all it takes to get it corrected. Also if you ordered a 5 gallon pail of ES plastic it states you will be charged actual shipping.
The colors I use most are X2 purple with .40 black flake in it. Also oyster shell wich is just clear plastic with blue hi-lite powder and some black flake in it. Pro blue and that is just a light smoke with a little blue hi-lite powder. Also you can make a good pearl white with just regular pearl powder in clear plastic.
Squach I'm not trying to spend your $ but you should just go ahead and buy 5 gallons of plasticol. It gets expensive buying in small quantities especially when you have to pay Shipping. If your like me and you end up obsessed with this hobby you'll be surprised how fast you use up 5 gallons.
And as already stated you'll be making baits for all your friends too.
As far as I know a slide bar mold is the only way. You can get a little bit of a core by pouring plastic in the sprue hole the injecting threw it but it won't be consistent at all.
I like the idea.
I would like to point out that when I've left unpainted jigs in contact with plastic the lead has a reaction with the plastic.
It was Do-it plastic and I've now switched to Bait Junkies but haven't tried leaving any lead in contact with the BJs plastic to see if it does the same thing.
AP if you get to it 1st let us now how it goes. I'll do the same. I've got the handles off already. I beleive your right, the pressure washer would probably do a number on those handles.
I've got a couple I got from a guy who stored them in a bucket of lead. They have alot of the white oxidization on them. I hAve tried a bunch of stuff guys on the Do-it forum suggested including clr vinegar and borax. None of them have done much good. I think I might try your idea AP next and pressure wash them.
The closest thing to what you want is the pencil sinker wich is bigger than you want or the finesse drop shot you could get a half and a 5/8. For the drop shot you would have to modify that mold for your application. Which would be pretty simple to do.
Honestly I think most of the manufacturers making cnc molds are good. For me it comes down to who makes a mold for the bait I'm wanting to make.
I have a lot of Do-it molds and really like them. I think Do-it molds have awesome detail. I also like Baitjunkys molds and think he puts a lot of thought into making them so they shoot perfect every time. Just wish he made more crappie and walleye style baits.
I also have some Bass tackle and Bobs tackle shack molds I like.
I use quite a few jacobs molds for panfish baits.
