Our carpet is thicker than our flooring.. so I was wondering, could I install the threshold molding that we have backwards? I.E with the thick side either butted up to the hardwood or slimming it down until it sits on top of the hardwood. If so, what can I attach them with? Liquid nails? Also what can I use underneath the lip to prevent it from rocking.
And before anyone suggests/asks.. we can't use a reducer, or any sort of header board because we have a cat who likes to pick at corners to get to carpet strings.

I understand that usually it us done the other way so that the wood can expand/contract..but,we bought 4 of these threshold strips for our install (by recommendation of the supplier), so we would really like to use what we have. The hardwood being installed is nailed down 1/2 inch engineered brazilian cherry.

Thanks!

Here are two illustrations to help:

you could run a fir strip under the part overlapping the carpet for support otherwise its prob gonna crack. Other option would be to get rid of the cat or its nails one.

Instead of that big honking thing just use a T-strip, Just glue and pin it to the engineered so it moves with the floor. Tackstrip under the other side will support it enough. I don;t understand the cat thing though. If your wood is run under the door enough the cat cannot get to it.

Other wise just do the second one. The first pictorial you have will not let the floor move in that area.

Well the thing is we have already bought the threshold and there's a restocking fee if we return it (so we are trying to use what we have). What we might do though is do the second option and glue a piece of scrap wood in the middle of the threshold to make a make-shift t-molding.Then possibly buy one of those t-molding tracks (http://tinyurl.com/4nzkcsn), or attach it to the subfloor in some other fashion.

That only works if the door is closed... this transition will be in a total of 7 rooms, so it's not quite feasible to be able to keep all the doors closed all the time. I don't understand why he does it, and we don't want to get rid of him. De clawing would not fix the issue either because he goes at it with his teeth.

The only s lution I think You have with a carpet eating critter is get all hardwood floors!

Haha with a 3500 sq ft house it's quite expensive. We are already doing about 1500 sq feet, plus I don't want hardwoods in the bedroom.

I hear that. I want mesquite floors and doors.

What is that tool your using in this picture? Is that a carving knife?

Wow, you guys are awesome on the stair treads. I woulda just ordered some.

lol, nope it's one of those fold-out wood cutting saws (I did not cut the whole thing with one of those.. just towards the end)

Thanks for the compliments... we got a quote on doing the stairs and it was something ridiculous like $10,000 to do everything. I think we will end up spending somewhere in the $3,000 range... still have to make 3 box newel posts and get the railing/balusters up. I don't know what I am going to do with myself when it's all over lol.

But in regards to the original post.. I found this: http://www.safetstrip.com/ yesterday and plan on trying this out, making a tack strip similar to that, and installing the threshold like it is supposed to be installed. It's the frayed edges that the kitty in question just loves to eat, so hopefully this works!

Yea, I can't get that safe strip here because either 1) the installers thinks it's junk, or 2) the distributors thinks it's junk. ha ha I just pound dwon the pins in on the regular strip. Plus a little latex adhseive in the gap works better. Besides that, I don't follow you on how thats going to keep a kitty from eating the carpet.

Hmm we might use that latex adhesive idea. Our strange kitty likes to get the frayed strings at the end of the carpet, so if we fold the carpet over itself (and over a tack strip) he can't get to the ends.
