Grafting Attempts

I set up some grafts today. I am trying to get the Gibson's mineola onto one of my trees. I went by and got some cuttings from the Gibson's mineola one of there navel oranges.

I tried the following:
On my tangerine...
6 T buds and two grafts
On my grapefruit...
1 graft
On my orange
1 graft

Most of the it was using the mineola stock. I used plumbers tape for all the grafts. For some, I used some grafting wax.

I am mainly trying to get ONE graft to take. Supposedly, I will need to check the t-buds in 12 days. The other grafts will be checked in 3 weeks.
