Well done David 
I like the grain on the wisteria persevering with it and done well.
What I have done in the past with woods like this is soak them in the Ronseal wood harder, tin cost about a tenner. Pop the cut and drilled blank in to a takeaway plastic tray and pour it in and watch it soak it up..
tin of the stuff last well and can do loads of blanks.
Still need a little CA but much easier to turn.
