Photos 1- 2 just show top covering on center and outboard wings, need sanding but should keep the warping to a minimum.

Photos 3-4 Went with 1/2" ply. firewall mounts, plus used Aeropoxy and bolts to secure to frame. I have seen too many firewalls come loose, I don't believe these will.

Photos 5 -7 A foam temporary insert in cowl so it can be mounted for measurements. Firewalls mounted and cowl fit to center.

Photos 8 - 14 This is the dry layup of the scale gear doors for the B-25. I increased the diameter of the nacelle by 1/2" to better match the cowl. If you look you can see an extra support plate on the outboard side between the two nacelle formers. All side formers were increase 1/4" in width and aligned for a 'straight down the side look' as per scale. Extra side formers are required for the door arrangement. Nacelle is already too high top of wing to bottom of nacelle so I left that dimension as per plan. Nacelle is also 1/2" - 3/4" too short so I will be looking to move back about 1/4". There are two new formers on the front, one to hold stringers and another to cover. This will push the firewall forward 1/4" which again is more to scale. As Sam points out this helps with CG as the engines are moved forward. He moves forward an inch so this 1/4" should work well.
Inboard gear door is wider than the outboard door and follower door goes pass the center line and follows the strut while hinged on the inboard side.
Scale measurements were made from three different scale drawings that I have and then compared to see if dimensions were the same or similar, this was done to eliminate an oddly drawn supposedly scale drawing. All measurements were very close to the same so I am confident that the scale size for the different doors is correct.

More measuring and fitting will be required to get all stringers straight and in correct position for the doors, Note that stringers on and along the doors are in spruce. Putting the skin on looks to be interesting and I will use Sam's technique of cutting the doors out of the applied skin. I will try and use pins stuck through the skin to identify the corners and lines to get the cut lines correct.

Also you will notice that the gear has been moved back to keep the wheel axle at the correct location as per the plan.
