I spent a long time looking for new window sills for my beautiful 1930s home. Window sills with a beautiful, sturdy, authentic look. Through I came up with the idea of ​​making them myself using oak carpentry panels. Result; beautiful oak window sills for my 1930s home. Window sills in the bay window of the living room and also in a bedroom and study.

Solid oak window sills

Living room;
The bay window actually has 3 surfaces;
- A middle part with dimensions 206 * 27 * 2.6
- Left side with dimensions 75 * 27 * 2.6
- Right side 78 * 27 * 2.6
A plank can be used for middle part, for the left and right sides I saw a plank in half. I also did some sawing work in the corners.

I thought it was too risky to buy this plank in its entirety for the windowsill. The house is higgledy-piggledy and measuring everything was impossible. Splitting it into 3 areas was the right solution. I first made a kind of mold with cardboard for the corners. I marked these on the wooden planks after which I could saw them off with the sawing machine.

I was able to buy 2 custom oak panels for the study and bedroom. There are no crooked walls or complicated corners.

I lacquered the window sills with Rambo armor lacquer transparent matt colorless.

The window sills were then secured with mounting kit and were The seams were also provided with a sealant filling.

I am very pleased with the end result, it turned out really beautiful.
It is also a project that you do not have to be very handy for, you have to be able to work very precisely as I had to saw some corners in the plank.
