First, press your finger into the wood on your windowsill and check which areas feel soft and are therefore, rotten. Then, make sure that the area you are going to cut out is slightly larger than the soft areas so that you are sure to remove all the rot and mark it up using a marker pen or pencil and ruler.
Make a vertical cut to the sides and back of the rotten area using the Dremel Multi-Max set to speed 10 and fitted with the Wood and Metal Flush Cut Blade MM422.
Run along the front of the rotten area with the Dremel Multi-Max fitted with the Wood and Drywall Saw Blade MM450 to make a lateral cut and remove rotten section. If the piece of wood is too deep to cut out the rotten area in one go, then cut it out in sections.
Mark up your new piece of hardwood with the right dimensions to replace the rotten area, then, cut out using the Dremel Multi-Max fitted with the Wood and Drywall Saw Blade MM450 set at speed 10. Now you are ready to glue the new piece of hardwood in place using your Dremel Glue Gun 910 and 7mm wood glue.
Finally, face fill any gaps or blemishes with wood filler and sand using the Dremel Multi-Max Hook and Loop Sanding Pad MM11 and the Sanding Paper for Wood MM70W which comes in three grits P60, P120 and P240. Then prime, undercoat and paint to finish.
