Denis...would it be possible to flip the long arm casting upside down and put the long arm in the drag? It would make feeding it with a riser much easier. Forgive me if I missed something and am speaking out of my ass. LOL Also I noticed the shrink is right beside the riser and the riser itself may have kept the spot on the arm hot longer causing the shrink in that location. The arm being tallest part of the casting may actually be feeding the casting like a riser. If you cant flip it upside down maybe you can add a large round shrink bob on top of the arm itself to feed it...just have to cut it off. Just trying to throw out some ideas to help. Looks pretty darn good for the first attempt though! Congrats!
