What is the best way to insert the cross (finial) into the King?
Generally, you twist and seat the cross. However, the “wings” of the cross can break off rather easily, if you twist too hard. If it does not seat easily, you can use soap or wax to lubricate the shank. If it is too loose, a small bit of paper can be used to help wedge it tight. It is better not to glue it in, because then it is very hard to fix if it breaks. And it is almost always better to replace a broken cross, than the entire piece.
