We decided to convert the dining room floor to hardwood.I asked my wife “Do you want inlays to match the kitchen floor?” “Of course!” was the reply.When I asked my flooring guy if he wanted to do them or should I he said “You do it, my knees don't want to”Here are the steps:Make a template and lay out the design
Locate the template
I used a template guide on my router so the template openings are larger than the inlay
Cut the pattern and move the template
Flip the template to cut the other. Note the “length adjustment” for the long slot and how I place a nail so the hole lands under the inlay
Cut mating half
Use the short slot in the template to cut connecting groove. Get ready to cut sharp corners
Finish the corners
Cut a bunch of walnut sticks that are a tight fit in width
Trim to exact length, add glue and tap into place
Repeat until finished
Project took about 20-25 hours
