Method 1: 1. Use cement putty to level the stair treads first. 2. Drill holes with percussion drills on the cement step, then bury the bolts in the holes, fix them with marble glue or expansion bolts, and the height of the bolts exposed to the cement plane should be consistent, and the length should be two-thirds of the thickness of the solid wood pedal.

The bolt is a relatively flat nut.

3. The back of the solid wood pedal is milled out of the groove with a T-milling cutter in the corresponding position, and the direction of the groove is the front and rear direction, and the depth of the groove is slightly greater than the height of the exposed screw. 4. Align the solid wood pedal hole and nut, press it, and move the pedal to the direction of the kicking to make the bolt and nut stuck into the T-slot.
