I use JB weld. I fill the cavity then start drilling and pouring until I get what I want. If I go too deep, I put JB back in the cavity and start drilling again. I have one mold that has poured several thousand heads and the JB is still holding on.
I ordered hooks from the Captain back in January. They were back ordered. Over the last 7 months they have come dribbling in. The last ones came this week.
I use Calhoun medium for everything. I have hardner and softner if I need it but rarely use it. I have the Bear's tube molds. I don't use any salt in my baits.
Try pouring slower and fill all the cavatives to the point of running over. You may also need to fashion some spru extenders. I use copper pipe joints.
Do you have any trouble with the wire snagging your line? No matter what I did they kept getting together. That is why I switched to braid on the R loop.
Thanks for all the help. I've passed on the info. What they are looking for is flat eye ewg hook. So we shall see what happens and if or not something is purchased.
