Thanks Dean,

Those centres are lovely - giving me ideas now as my jag centres are a bit jaded.

Going back to zero is just force of habit I guess, after I went through a washer which I was using to clamp through a hole on a previous job (luckily I missed the socket head bolt). I must do a blooper reel sometime :)

Also true on the DoC, I was using 3mm per pass and the material was just over that in thickness (I just took it on trust from ali warehouse it was 3mm). I always add another 1mm pass on these days just to be sure, as I hate having to break parts out of the thick tinfoil I used to get by trusting the thickness.

I was as surprised as you regarding the 1000 series stuff - normally its a pig but for some reason that F&S went right through it and only left the lightest of tool marks, which I could probably breath on and take out (especially after a curry) ;). Guess I must have been in a sweet spot for a change, or just got a lucky batch of sheet/plate - the recipe though is a keeper I think :)
