You should enjoy this one Bob, it does have a few traps, so please check and dry fit frequently before committing to gluing, also go through my build and try my method with the floor and fitment of the elevator rod,

you can try the instruction method and my way by dry fitting to work out which way you want to go on this part of construction.
Also the prop housing gave me a tough time, see if you can adjust or fix that prob by dry fitting the complete prop before you go too far like I did.
