aggietexan, if you send me pictures to my email address, I can set them up in one of the two photo sites I belong to that I have not used in a long time. I would add pictures and send the link here and clicking the link would allow the pictures to show. I do not know how to place pictures inside a post but I do know how to do links. I would love to see pictures. Just click my lynn2006 page and you will see a link to click my email. I am glad you are happy with your new floors. Do they have some red in them? I would love to see some close up of the knots since maybe they are tiny and will not bother me. I do love the pics of the Amendoim floors on the BR-111 website. How long have you had the floors? What color change can you see if you have a carpet on the floor?

You need to do a little more archeological digging still. You need to know the whole construction of the floor before you can decide how best to install something new. I'd take up that plywood piece in the kitchen and see what's under it. It's higher than the surrounding floor, so needs to go. You should also be able to see from there what subfloor is under the original kitchen hardwood. It's too bad the space under your entryway is finished, but I'd still do some exploring from below to see what's under there, and to figure out the fix to stop it from squeaking. Is it drywall below or a drop ceiling? I know it probably seems like a pain to tear out drywall, but if you cut out a clean patch, like 2' x the width of the joists, it'll be relatively simple to repair. Just make sure to cut it down the center of the joists so that there's room to screw the patch piece to it later. Cut the hole under the area that squeaks the most, if you can. Have someone walk on and watch the floor from below to see what's moving. It might be as simple as pounding in a couple shims from below, or face-nailing a loose board from above. You want to find out what's underneath the hardwood. It might be laid directly on the floor joists, or there might be 10" wide boards that the hardwood is nailed to. Another thought is to take out a board in the hallway, since that's not original and you want to replace it. See what the subfloor is there. I am a bit puzzled at why, when you've stripped the kitchen down to the original hardwood, it's still higher than the hallway floor. Is your current surface perhaps not the original kitchen hardwood? Peeling back the plywood area will help determine that. BTW, I haven't heard of that stop squeaking product you linked to, so can't offer any personal opinion. And don't pour self-leveling compound over top of hardwood. It needs to go over plywood.

I'm not quite following your thoughts on the repair but they have used a piece of plywood between the old hardwood flooring and the new bamboo floor. It sounds like you want to remove some of the planks in order to have the voids filled with a continuous longer board rather than a short piece. Have you read about how to replace a damaged tongue and groove board? I think they cut along the joints of the board to remove the middle section and then chip the rest out of the T&G areas. Placing that one new board in would require removing its tongue in order to be able to slip it into place next to an existing board.

Laying the new floor in the same direction as the old floor is not the normal way to go about this. In the building industry, it is more common to see layers that are staggered or "bricked". In other words if layer #1 is laid in a North-South direction, then layer #2 (the top layer) is laid perpendicular to it in an East-West presentation. If you want to run the new flooring in the same direction as the old, you will want to use some underlayment (plywood) over top of the old floor so that you can maintain the "staggered" or "bricked" layering system. That is one way to maintain the North-South presentation. Please work with hardwood flooring professionals who have some experience renovating these old gems. They will have seen what worked....and what didn't. Their experience will be invaluable on a project like yours.
