After 10 years of commercial pouring finally figured out that smoothing out a Do-it gate can greatly improve flow through it. Actually, opening my poured new No-Snag sinker mold was causing ugly gouges in the eye caused by the casting being forced off the pin at an angle due to mold sticking in both halves. So, alls I did was razor blade the rough spots out of the gate on ONE HALF OF THE MOLD and problem solved - the smooth gate half released the casting easily leaving it stuck in the rough half to be gently pliered out with no damage. But, the fringe benefit was that where formerly the melt was backing up at the gate requiring precision pour placement and drop volume to avoid gate freeze the melt was now flying through the gate with no back up even with only 1/2 the gate roughly smoothed. Been a lot of posts recently about tough pouring molds so this might be another solution possibility.
