Does anyone have a good technique for creating a housing on posts for bearers, Im using a circular saw to make cuts in the posts the same width ad depth as the bearer and chsieling it out and finishing it with a plane unfortunately I'm making a bit of a mess out of them out of 3 im only happy with one as they are so expensive i cant afford to keep making mistakes .. Is their an easier way I was to do this , can you pay a timber yard to cut these out for you .... thanks Paul
