W2, Thanks , I’ll need to add another short crossmember where the nose attaches ... and a few spacer blocks ... Putting the ribs together should be fairly easy ... if I can get some help to just hold things while I nail and glue it together ... I did borrow a pneumatic brad gun to help , that should make it much quicker ...
Norm , laying the X-members flat works best for me , makes floor attachment much more secure (easier) even though it’s T&G edges . ...I’m using “clear and dry” treated Pine cross members which seems very strong , and there will be enough of them to provide enough strength for the light cabin structure ... The overhang is 11.5” on each side (3.5” of that will be foam ) , and will be further reinforced by attaching the OSB floor , so I’m not worried about the strength ... and yes , I need to get out the chop saw to cut them to length ..
I would have gotten more done , but yesterday afternoon , the yard men showed up to help me remove a broken 40’ “hanger” Live Oak limb from directly over my driveway .

Had to get my bow out to shoot an arrow with string attached over the tree so we could attach a rope and yank the darn thing down ... Then we had to chain saw it up and toss the short bits into the woods ... After that I was too shagged to do any more work ... (old ) and had to rest ...
Now I have to clean up the Studio for band practice tomorrow night , so assembly will have to wait till Saturday ... and it’s supposed to rain More today ...
