Here is a small list of materials:
1. SS wire 18 and 20 guage (soft wire)
2.ballast weight (egg sinkers, finess weights, bullet weights)
3.wood (balsa and cedar are the woods I've used)
4.bill material (garolite and/or lexan) buy pre-made if you can
Take your fav crank and make a profile copy of it on a copy machine. Mark the lip angle, line tie, and hook hanger positions. Draw the pattern on a 1/2 thick board and cut out on a band saw or scroll saw. Cut the lip slot first while the stock is still square. Mark the center around the blanks and drill ballast port on a drill press, drill out line tie and hook hanger holes.
When you get this far make another post with a pic of the bait. I will take you the rest of the way. I'm better at building than teaching, just bare with me.
