Hi James
I haven't. But I'm still digging.
I use rails and stretchers like you. (I think, (every one does things differently)
I have attached some units the way I have done some of them and would be interested if you do them the same way.
Its always surprising to me that a bog standard oven unit can have so many variations. It always seems that when you put constraints in you have to change them.
Wally we may have different local regulations but all the ovens we've used in the last 10 years get put into a 600mm (about 23' 5/8") external unit, All seem to be European imports
This is one feature that’s on my wish list. Position your cabinet or assembly around the target. Open a dialog box that asks you, do you want to add on or take away, above or below, to the left or right of XX YY or ZZ. Press the button and WALLA! Too easy.
Ps I don't have a router so I have no idea how they would machine.
