Many thanks everyone, just turned on my computer to be welcomed to all your comments. Just to respond to woodbloke’s comments about time and faffing around, I am the world’s best faffer in my workshop (garage) I can spend hours up there just standing around thinking to myself ‘well isn’t this nice’, and it’s not like I don’t have hundreds of jobs to do.
After all your comments I have decided to invest in a new set of router bits and make myself a mortising jig, that way I can do the mortising and have more router bits for other jobs. Just need to find plans for the jig.
All the best
