Bracker Core below Sleeve1) Now today question is below the direct pour sleeve we have a breaker core or a circular pad generally 10mm in ht .some people keep it with 25 and some 30mm.what is the min ht of the pad and then there is a riser base cup 2) Is there any ratio of riser base cup to the dia of sleeve 3) Riser base cup height or depth to riser dia....because it is this part of system that impairs the yeild uf it become too chunky
4) Joshisaheb Pl go thru the above sketch(I am bad at sketching) 5) There is no breaker core required for a direct pour sleeve 6) I used breaker core- otherwise digging while breaking the riser 7) If direct pour sleeve is attached to running system with sprue well, then breaker core or "h" is not required.
