Try checking on Paul Dobbins website....www.trapperman.com he has a catalog with his dads books.As far as chopping a hole in the ice and removing the chips goes....Get a long handled sqare tye shovel and blow some 1 inch holes in it with a cutting torch.The long handle is nice cuz ya can stand on the bvr house in a safe spot.I use a husky chainsaw fur choppin some holes.I file my chain teeth straight across and use ripping chain.I also own a Jiffy Mille Lacs ice chisel...best chisel I have ever owned.When I am yodle dog trappin i wear a thin pair of cotton glovesunder big mitts.I put the mitts on a string around my neck and when i stop...remove the mitts and don t have them on the ground filin with snow.as for yur question on yote trappin depends if ya wanna use legholds or not.Hope this helps....:hat dang i con should be sportin a fur cap.Best of luck to ya....Zepf.
