Sparce,

I just asked the boys in back (break time) and they all said go the route of Stainless to prevent future corrosion. They didn’t even think about it, it took them 3 seconds to say it.

Good luck

You can tap cast, but go slow and you can't use too much lubricant.

Another option is to use self tapping screws.

Stainless. Use stainless.

So with self tapping I should'nt use a drill motor? screw them manually? Pilot hole?

I would use a pilot hole and stainless machine screw/bolt. If you use self tappers, just go stright,slow and use correct size pilot hole. Try by hand first and if it does not go easy, start a cordless on light and adjust speed to slow r.p.m.'s. You do not want to bind up and break screw (smalled self tapper could break). Most times if you get the right pilot hole size, by hand you should be able to sink the screw nice.

Good luck and go slow.

You do need to exercise some caution, cast iron is pretty brittle compared to steel.

      1-24-17 Fishing Report The fishing in the 30-33 feet of water range has been producing several limits of 14-17 inch Walleyes and Saugers with a few smaller yearlings in the mix as well. We have also seen a few perch around the 12 inch range as well as a few tulibees and pout coming up the holes. The fish have been biting more timidly so patience before setting the hook is a must. A plain red hook on a dead stick continues to produce a decent number of fish as well as using smaller jigging spoons,rattle spoons,buck shots and stop signs with glow in the dark pink,green,blue and gold being the effective colors. The hot times for the bite seem to be between 10 am-4 pm with a decent number of bites being reported between first light to 10 am. The bite in the 16-20 feet of water range has cooled off a bit with a few keepers still being brought up mixed in with a handful of yearlings. The flashers continue to be a highly recommended tool up here on LOTW as there remains to be a decent number of suspended fish being seen.  Good luck fishing on beautiful Lake of the Woods!

      Trout fishing thru the ice is a blast!!!   Their hits are usually aggressive like that, makes it exciting. They put up a pretty good fight too.
