Thanks to Northern Hewer and Mark Davidson for responses to my questions. I have a couple of plumb bobs which as you say are always useful. As far as the level goes, I suspect I went a bit overboard, but I went with German engineering and bought a 59"
Stabila set from KMS tools(no affiliation) . I'm sure it will be useful for timber framing as well as
foundation work and interior work(doors, cabinets etc. The set includes a 16" bonus?? level.
Thanks again, If I can't build straight, plumb and level with the stabila, boy will I be red faced.
