I have made over 100 this winter and I use the HT JL-3 Little jigger 25″ ABS plastic handle. You need to consider the height of the stand to the length of the pole if you are using a design that is close to the ice.
The wood handle poles look pretty but we have them balanced to delicate that the wood varies enough to throw the balance off.
The ABS Plastic is strong and the consistancy of the material makes it easy to use the exact same balance point. I do sell them for $20 each with a pole and ready to fish. You will have a hard time building them your self for that price. Consider the price of the pole, wood and plywood for the frame, line, terminal tackle, bolts and wing nuts.
The only way I can sell them at this price is my dad has the lumber from trees that we cut on his land and we sawed into lumber on my cousin’s porable sawmill. My sister has a giant woodworking shop and I buy the poles direct from HT. I have a dealers account setup with them that gives me a discount on large numbers of purchases.
If you want any tips and more info on building them feel free to call or PM me 715-379-2376 Charlie
