I bought a few of the glow hole sleeves for my IC Little Jigger. Here’s the thing, I sometimes block my house and sometimes I don’t. I plan on cutting them 5″ from the top lip, then I can use the bottom halves as extenders, inside the sleeve, when I block it. I don’t use 4x4s for blocking, I use the slightly smaller timbers w/rounded edges, that are under 3″ thick. So in reality, I’ll never be more than 8″ off the ice.
I also have thermal hole sleeves from Hardkor, that I got at the Ice Fishing show. These are also 9″ and can be folded – they fit perfectly around the outside of the plastic sleeves and will offer additional insulation. I can also use them as extenders as well. They had a deal on them at the show and I wasn’t going to get plastic sleeves, but they’re kind of stiff and they come folded.
What’s the easiest way to cut the plastic hole sleeves, making sure the cuts are straight? I did some searching on the internet couldn’t find anything. Dremmels are kind of a pain because their cutoff disks are narrower than the tool, so you’re always cutting at an angle. Would I be better off using a guide, drawing a line and just use a hack saw free-hand?
