i know this is kinda a late reply but anyway about what type of wood i use.. i mostly use hardwoods like oak or maple for jerkbaits. about the through wire vs screw eyes, i i make baits from softer woods like balsa then i would defineatly use through wire, the screw eyes wont hold in that at all but with hard woods its very secure with some epoxy not to mention its soo much more faster to use screw eyes than sawing the slot to hold the wire.
currently i have not made any video regarding the actual shaping and cutting the blanks i have not had the time to make that yet, countless people have asked me to make one of those so maybe at some point i will get round in making one.
