Thankyou for the PIC's
They have proved very helpfull and answered a few questions, one was what the curve was for under the fire wall - : this I supect is for a RE 61 and a pipe, I won't be building mine with this feature but it could be a option, I am adding a extra former in the centre of the wing area as showen in the photo.
I am a bit closer to finishing my plan.
Should have it sorted at the end of the week.
Regards
John
