Weird Angles + Furring Strips

Well this was a project neither of us expected to take so long! We thought we could finish in 3-4 work days but it ended up taking 10.

To prep for this, Paul had to do a little cutting to remove a metal lip just below the windows. Once that was done, we used 2×4’s to frame the walls and plywood wood for the ceiling. We then installed them with adhesive and wood-to-metal screws.

This project required a lot of screws!
The beginning
The middle
The end

Fun fact about Thomas school buses like ours – starting at the bottom of the windows going up, the walls tilt inward. So those wood pieces had to be cut at an angle to maintain a flush surface to mount our walls to.

Check out that tilt!

For the ceiling we used two strips of 1/4 inch plywood. Because of the corner angles of the ceiling ribs, we put up long strips across the middle portion of the ribs; then in the corners we cut down smaller pieces of plywood to attach.

A few other things we need to do before the bus will be ready for insulation: install ventilation fans, frame the skylights and install wood blocks for interior wall framing.

Check out a video of the work:

I want to also share another bus tour from a couple we met at the Florida home festival back in November. They have a neat story and Roman is actually helping us with our electrical wiring in the bus. Enjoy!

  1. We’re having this same problem right now. Thanks for the info! This may sound like a stupid question, but how did you guys measure the angle at which you had to cut the upper furring strips?


    1. Hey! There are no such things as stupid questions! And I used a very crude method to measure the angle: I used a scrap piece of plywood and a 2″ piece of furring strip. STEP 1: I placed the furring strip up against the angled window frame. STEP 2: I placed the plywood up against the side of the furring strip, but perpendicular to the floor/parallel to the wall(having the framing up to the bottom of the window sill helped a lot! STEP 3: I traced the edge of the furring strip onto the plywood. Thats was my template. i went one step further and made a table saw rig to cut the furring strips at the same exact angle each time. Don’t quote me on this, but I believe the angle is 6 degrees. NOW, with all of that said, you could buy an angle gauge from harbor freight for $5 possibly. Hope this helped! Let us know if you have any other questions! Good luck on your build!!
