Hi again folks, I posted the below message at BGI!

Heat can stress a *whole* Sanguinea plant so much it can die.
In theory...
If Sanguinea was grafted on to a heat tolerant rootstock like Charles Grimaldi, the Scion (Sanguinea) although it may stress, has less chance of dieing as it's roots are unafected!
If this or a similar graft was possible, it would also make for less water sensitive sanguineas and vulcanicolas!
It would also open the doorway to the possibility of *Graft Hybrids*. These asexual hybrids are new plants which arise from the grafting point and contain tissue from both plants.
Are there any experienced grafters out there?

What's anyones experiences or thoughts on this? Is it possible? It'd be great if a number of us experimented with grafting this year!
Cheers,

Grafting possiblities!
Bruno,
I do have a good friend that grafts trees I can ask him if he would do the grafting for us if someone would send me the Brug cuttings.
My father grafted apple trees, etc. I will try to remember just how he did it, I watched him lots of times, he used bees wax, this was before plastic wraps, etc. He cut a groove in the rootstock, made a sliver to place into it, of the 4"-6" graft piece, then sealed it shut. Can't remember how long it took, but when the graft started to grow, you'd know it "took".
I know how to graft, i've just never sucessfully done it before..LOL
Never had to, as dad did it all, I may try some day, when I have a lot of time, whenever that may be?
Eric says when you want to graft a brug its easy.I wish I knew where the link for that posting is

Here it is Karyn.
Yup,thats what I was looking for,
Well,I have a sang cutting rooted,I'll look for something to graft it to.......I have some of that stick to its self wrap.........
Whew thats all over my head.
Here's some grafting techniques: http://www.ces.ncsu.edu/depts/hort/hil/grafting.html
But if you've only a few small plants to work with and you'ld rather not start chopping them up, you could always try bud grafting: http://www.ces.ncsu.edu/depts/hort/hil/budding.html
And here are Eric's methods!
"Making Brugmansia grafts.
Method one, place cuttings in the corners of two square pots. Root them both. After they are fully rooted pull both out of square pots and wrap them together at 2 or 2 places using a 1/2 to quarter inch wrap. Place in a pot together. Let them get over the shock of being moved and resume normal fast growth. Remove bandages and make cuts that face each other. Wrap them back together in the same manner. This process makes a very nice graft in about 4-6 weeks in most cases. The actual graft only takes 2-3 weeks to fully form.
Method two, using a fully rooted large Brugmansia, place a seedling or rooted cutting still in its pot alongside the branch it is to be grafted to. Secure the pot to the branch with a wrap. Make cuts that face each other on the branch and on the seedling or rooted cutting in a pot. Wrap the cuts together. When making your cuts remember that you are just removing a bit of the outer bark. Not enough to actually see the inner wood, but it is okay if you do see a bit as they will heal up. Water and fertilize the rooted cutting in its pot and water and fertilize the large fully rooted Brugmansia as well. After the graft is fully formed, gently cut the smaller cutting or seedling to remove it from its roots and the small pot. You can then either leave the grafted Brugmansia in the top of the tree attached to the branch or you can cut the branch just below the graft and root the new graft on its own."
Here's more usefull info on graft hybrids:
In the area of experimental synthesis of graft chimeras (Hybrids), most work has been done on species in the Solanaceae . To produce graft chimeras, a scion is grafted onto an understock. Then the scion is carefully trimmed until only a thin layer remains, callus formation follows, and then shoots form. Some of these adventitious shoots may be chimeral . Graft chimeras are chimeral for numerous traits. The potential exists for the exploitation of this method to vegetatively create disease or insect resistant plants, as shown by the synthesis of a whitefly resistant Solanum pennellii-Lycopersicon esculentum graft chimera.

*Synthethic graft chimeras*
Within the family Solanaceae a number of graft chimeras were synthesized. Examples are:
Lycopersicum pimpinellifolium + Solanum nigrum (Brabec, 1960)
Solanum tuberosum + Lycopersicum esculentum (Jorgensen 1927)
Nicotiana tabacum + Nicotiana glauca (Marcotriguano and Gouin, 1994)

Appart from a very sharp knife, here are some other things usefull in grafting :
GRAFTING TAPE: Tape backed with biodegradable cloth; used in budding and grafting operations and in banding tree wounds. Also called nurseryman's tape.
GRAFTING THREAD: Fine waxed string used in budding and grafting operations.
GRAFTING WAX: A waxy substance used to hold and seal tree or rose grafts.
