packing sorbent inside column

[optimoprime]

How would one pack a preparative scale, medium pressure glass column with C18 sorbent material consistently both wet AND dry? This is an expected obstacle as I try and obtain reproducibility. I suspect simply engaging the vacuum, loading the bottom frit, sorbent, top frit and pouring on a few column lengths worth of solvent oughta suffice. Could someone maybe offer any guidance on this subject.
