Got myself a real gem of a transition to figure out.

https://www.dropbox.com/s/1okbqbibq3hym ... r.pdf?dl=0

Older house that we installed a new kitchen in.... the tile was laid level, 24"x24" tile, so we could cheat for the huge high spot in the middle of where my transition will go.

The photo shows the high spot in the middle of the transition run of 9'.
3/4" at either end tapering to 1/8" ish in the middle.

Anything I have ever done for custom transitions have been a taper.... which in this case will both become substantially thinner AND narrower as I sand down the transition to achieve uniform height at the top of tile edge.

I have some 3/4" x 1.5" maple to make the piece, but I can't see how I'm going to ramp up to the tile at 3/4" depth as well as cheat something at the 1/8" middle?

Thoughts?

Thanks

An electric hand planer will cut the back of your moulding very easily. Keep the slope at 15 degrees. Ease the edge where the wood strip is to meet the tile. Keep the full width of the reducer and only remove the underside. A wider reducer would help. Flooring distributors will have a ¾ X 2- 1/4 inch reducer for a few dollars a lineal foot. Use 18 ga. finish brads to hold the reducer after you glue it down with construction adhesive. Leave a gap of one-half the grout width between the tile and the reducer and fill the gap with sanded caulking that matches the grout color. After puttying the nail holes apply a coat of finish that matches the floor on the reducer strip, you should have already applied two coats before it was installed. Coat the sanded caulking with your floor finish that you use on the wood strip.
It is recommended not to fill a deep gap with caulking. Use some foam to build up the gap to within a quarter inch of the surface.

What's the height difference between the hardwood and the tile? Does the hardwood have a high spot in the middle of the floor?

Pete has an idea. Glad to have you on board Pete

Whoaa. 1/8" in the middle? That's gonna split in a hearthbeat once someone walks on it, unless ...

I don't have an answer, except a toe stubber saddle will probably work. At least it won't split in the middle. Still though, some creative wood working ahead of you.

Plane the wood floor too maybe?
