Nicely done. You need to anker your endposts or they wont stand the tension from the wire.
Peaches are more difficult to espalier because of their fruiting habit. They fruit on last years wood only. Plus peaches tend to get blind wood in their older parts. There are some forms of espalier for peaches (pretty much what fruitnut does in his greenhouse). But cordon training is none of them.
I don’t know about persimmons.
Quince in general can be trained as a cordon espalier. But they fruit at the ends of their shoots. It might be difficult to keep the form of an espalier and get plenty of fruit with quinces. But I didn’t try to espalier quince.
In general all fruittrees that fruit on spurs is very suitable for cordon training. Pomme Fruit are easiest cause they fruit on very long lived fruiting spurs.
But you could try everything else and report back about your successes and failures.
Thank you very much carot, I will make the Anker. For the last 3 trees will plant Japanese peers, they look nice and produce quality fruit. This weekend I will try to make some mulch with my new electric shredder, hope to do good wood chips. Thanks again for all the help!
