AAWWww come on guys , he`s new & I can tell ya his melt needs heat ,but the mold will never warm up if he`s picking em up or rolling em around to look at em !!
THAT IS NORMAL !!! & WE ALL DID IT !!!
Now , clean ya mold AGAIN , preheat it , to be shore ya read on CastBoolits `bout lubing ya mold with BullShops Sprue Plate Lube or synthetic 2 cycle oil, go sparingly ,it don`t take much .
Now if the mold is still giving trouble (It would help to know if it`s steel/aluminum/brass) & is new it`ll take a few heat cycles to purge all the machining oil from the pores, until then just smoke the cavitys with a butane liter(I prefer bic , sems to make a liter film , better quality fuel??) litely as needed.
Anyways , try the above before adding any tin any higher than 4% does`nt help hardness & benifits on fill out lessens also . I myself have to keep reminding myself NOT to rely on temp & tin to make up for bad technigues.
Just remember preheat(dry) everything before adding to a melt.
Have fun ,don`t let it turn into a chore, be safe!!
