Another neat job crowie... you should be able to do these with your eyes closed.
If your first cut is too short... Take the second cut from the longer end... LBD
Not quite with my eyes closed Alex, too many sharp things in the shed and being on aspirin it's a bit of a very bloody mess when they bit!
More so, I'm very appreciative of Jan [aka Dutchy] offering the plan, that he developed, around the information I supplied and my original project build, being available for free.......
