Okay, I build a 2.5' cardboard model, and am currently working on a full scale cardboard (to then use as templates) and have come up with a problem.

In the plans, there is a Rectangle on the same sheet as the frames and paddle labled "Floor Butt Block" When I built the 2.5' model, I omited this piece and made the floor out of one solid piece (same as the sides) but then the bottom was too short. Am I to assume this is not a "butt block" but more of a center panel fo the floor? Perhaps the problem is my understanding of the terminology. To me, butt block refers to a strip of plywood to be used in a splice, this piece overlaps each side of the joint, and the two halves join each other in the middle of this piece. Is this definition correct? or am I confused? Well, I know I am confused......

The piece is not a butt plate but an intermediate piece between the front and rear floor panels, and your bottom will be too short if you omit the piece.

Sorry wasn’t logged in at the previously one.

I'll have to re-label that part.

Great, thanks Matt

Okay, I had hoped that was the case. I havn't assembled the full scale cardboard yet, but made the 2.5' model by blowing the plans up on the copier at work. the page with the bottoms was a hair smaller than the rest, so I tried to "add a little to the ends" and it worked fine for the lower panel C, but the floor was way short.

Thanks!!

Careful

Those are not draw to a constant scale. They were drawn up with the intention for easy viewing and best fitting onto a sheet of paper. That may account for the difference in size.

That's why I wondered about that extra floor piece. I didn't know if the copying of the plans distorted them, or If I needed another piece. I know I needed another piece for the 2.5' model.

Panel is re-labeled now.
