I'm Looking For A Particular Type Of Strike Indicator Mould For Smelt Ice Fishing..?

[B.T.R.]

When I ice fish for smelts I use a small hard foam ball that floats on the top of the water in my ice fishing cabin hole. The ball has a small hole in the center of it to pass my line through and i hook my line on the ceiling of the cabin and let the line go into the center of the ice fishing hole. What this does is makes kind of a sliding bobber that floats on the top of the water and when the fish takes the hook or bites it moves the little float telling me i have a fish on. I have found something similar to it called a strike indicator but this type has a peg to put in the hole to hold the line in place and it is said it is mostly used for fly fishing. The bobber that I want to make is similar but i want it to slide on the line when i bring the line up without using the peg to stop it. All i wanted to know is if there is a particular site or web address where i might find a mould to make these small bobbers and what i should use for the foam or if they sell that too.

I see your problem and as an obsessed fly fisherman i think fly fishing holds the answer to your problems firstly there are purpose made indicators for fishing in the ice but i think this might also work, slides easily on fly line
