Pruning Japanese Maple's

Tips, Tricks

1. Japanese maples are my favorite trees. 
2. Can someone reply on how to reduce the height of this tree? And maintain it every year? It's about 10-12 ft now.
3. Thanks! 
   
   I have some thicker branches that show no leaves or growth on them, while the rest of the plant remains beautiful and leafy.  How would you trim the much thicker branches/ With what tool? 
   
   Would you leave the branches exposed on the ends of the cut part or do you have to do something to the stumps?
4. This video is awesome I just tried this method on a maple i have in front of the house . I have been scared to touch it up to now . I cant thank you enough for the great instruction 
5. Thanks for this great tip! I'll trust a British gardener anytime. Going out now to make my very large Japanese Maple a little smaller now that I know how to keep it looking nice.
