Make sure your "tin can" is actually a "steel can".
And if your rocket hangs up on the rod or the motor is too close to the steel can deflector, it will burn through the steel in a fraction of a second since the exhaust is like a cutting torch.
This is why the Estes deflectors are so thick.

The next time you open a tin can, save the top. Drill a 3/16 or 1/4 inch hole off-center. Take a motor casing and sand the ejection end at an angle. File, sand or grind the sharp edge off of the tin can lid. Drop the motor casing on the rod angle side up. Drop the tin can lid on the rod. Cost: ~15 minutes. Mine have lasted for over two years.
