FF2 + FF3 lenth help

[richardwarry]

hi all i need some help with the lenth of ff2 and 3 i have printed out the updated and help sheet but FF3 is 359.5mm long but the book is 320mm yet no mention on the book length wrong so not sure what way to go

Someone correct me if I am wrong but from memory the longer length is the piece of box you need the 320mm is the distance between ff1 and ff4 meaning the gap ff3\4 sit in once the angles are cut

many thanks got there its the first book out again as page 162

290mm to v + 69.5 to v = 359.5 as update sheet yet book shows bar to be cut at 320 good job i double checked
