   What kind of hinges do the "normal" doors use? There are Euro-style hinges for bi-fold corner cabinet doors: http://www.leevalley.com/hardware/page.aspx?c=2&p=40423&cat=3,41241,55420. You use regular hinges on one edge, and the bifold hinges in the middle.

   Thanks,
   Yes the others are euro. I think what my problem is, is that the edge has a profile. Looking at the tech notes for the Blum bi fold door it appears that the inside corner does not have the profile on the door.

   I think it will work with a profile, but you might have to fiddle with the hinge offset distance to get everything to clear. Unless the two doors have been specifically designed to "mesh" together, there will inevitably be a slight gap between them.

   What I think the problem is going to be is that the 35mm cup hole will come through the profile. The hole is centered 12mm from the door edge. I'll take a piece of scrap, profile it then drill to the hinge specs and see where we are.
   Thanks,

   Steve,
   Thanks for your help. I went ahead and made a mock up of the bifold corner complete with similar edge profile. After about 8 attempts on the mock up I got it to fit with only about a 16th gap. Boy I was sweating it, thinking I may have had to cut the door and fatten up the cabinet frame. Almost certain to have screwed that up. So now everything is ALMOST perfect. I have a little bit of a droop, 1/4" maybe on the opening side. It maybe just the weight of the door. I was thinking of putting some kind of small lip on the inside of the door so it's supported when in the closed position. Any suggestions. The doors are 10 x 30 and 12x 30, not excessly heavy.

   Hmmm. When you say there's droop, do you mean that you can actually lift the drooping corner into the correct position? If so, it sounds like there's something loose in the hinges somewhere, as there shouldn't be enough play to allow the door to droop more than a tiny amount.

   Steve,
   The hinge connections are secure but it seems that the weight of opening door (Left Door} is pulling the top of the hinge door (Right Door) away from cabinet frame at the bi fold. When I push in the top of the Right door, at the fold, so it's against the frame the droop is gone. Similar to slight racking. There's no play in the hinges at all.

   Steve,
   OK. I got it. I took the opening door off and the hinge door was still away from the frame so I adjusted the hinges on that door to make it flat against the frame and now we look good. These Blum hinges have more screws than a hardware store and trying to see them without climbing into the cabinet is really awkward.
   Thanks again for your help.

       Mike ,

                 You are correct the inside corner edges typically are left crisp and square without edge details. The Euro hinge is called a pie cut hinge for this application and as you saw the hole is only bored part way like a half a hole sort of .

             There will be a gap between the edges in the corner perhaps as much as an 1/8" , the hinge  allows the leading door to open about 60 degrees before the other door opens , and without the gap the doors can bind up . You will know if the hole comes through with the sample detailed piece you speak of mocking up and boring the half hole .

         One possible solution is to cut off the edge , glue a new piece on and bore your hole . We used to use piano hinges on square edges and I have 45° angle cut the edges and used sewing machine hinges on the back side of the door frame ( old school ) before the pie cut were made available to us .

           You may be able to save them  by mitering the edge , you cut the detail off , so depending on the exact detail on your doors they may be salvageable .

                   good luck     dusty

   Dusty,
   Thanks. Managed to work it out. It can actually fits with the profiles intact. But nerve racking attempting it.
