Anybody have experience with coring Jacobs mayfly mold?
See some great work done with the mayday mold but maybe the throat on Jacobs is a tad smallish?
-
I have E-cored Jacob's 3" curl tail grub mold and it works great. What is the diameter of the sprue on the mayfly mold?
-
These nano frys are about as small as a guy can get and they cooked up fine using the twin injector and some small brad nails. Both the twin injector and the brads on a bait of this size is pushing the limits but doable, so the Mayfly is probably an ok one to use. You can adapt mold to coring by opening the gates up some for a core wire without any real headaches.

I have E-cored the Mayday mold but I am not familiar with the Jacobs version. No offense intended here but there is only one way for you to find out. I would try to see how thick a pin I could fit in the mold cavity then shoot the plastic a little hotter than normal. A lot of trial and error doing some of these E-core baits but you seem to be getting it down pretty good.

2xl, i have not bougth it yet but looking at the magicians work with the nano's i guess it will work.

I looked through Jacobs site for his Mayfly mold but didn't see one. The only thing I saw that was similar ( Kind of ) were the Hellgrammite molds.

My bad 2xl, stonefly larva is it called.
Panfish baits 1-2 inch page 4 or 5 (i think).

That mold looks like it has a pretty small gate. Hard to say without seeing the mold in hand. You might be able to make a pin that covers each pair of baits or you may have to taper one end of the pin and make pins for each cavity. If you go the tapered pin route you will most likely have to trim a little bit of the head of bait off so the core colored plastic has as big an opening as possible to flow through the middle. Tedious work and a total guess on my part but I think the body of that bait should be big enough to E-core if you wanted to. At least with the bigger Stone fly.

The nanos are an inch long. In the picture with them and the mold you'll see the brass brads I used to core them. A hobby shop where they sell brass rod in small sizes or even some piano wire that'll fit the gates of that Jacobs mold will also work. I didn't see the mold per se in the Jacobs site so I can't really tell how much wiggle room there is but still the gates can be opened up a hair to accommodate some wire or brads. I could sort of see the shear off point on the bait Jacobs shows and it looked very close to the nano's cut-off area so I think you'd be fine. That bait at 1 3/8" should be a super good bait core or not.

I've got the 1" stonefly. If I get time today I'll take a look at it.
