RE: VIDEO OF MY NEW MAGNUM
If it's not to close to the fuse (like a 1/2" away or more) just put some 2oz glass cloth along the break on both sides, just saturate it with thin CA. If you don't want to do that (since it will show through the covering after) then put in a couple of spruce spars. Another option is to use some 1/64" plywood, you can put a cover over the break on both sides and use some drywall spackle to blend it into the stab, then you'll never notice it was there when you re-cover it.
