Rich... No Worries on the recoil. This is my 5th T23 Turret (6 if you count the Jumbo) Each one has been done a little different and so far so good.
Bob. My very first tank was an "expedient Jumbo" 4th AD style. It was the first "DAK" Build on my website. After a few upgrades it still runs just fine!!
