Here are some tips to make constructing the bat boxes easier:

  1. Saw loss measurement is factored into the sawing diagrams, but not the construction diagrams. You will lose about one-eighth inch to cutting. This is for both sets of plans
  2. Use one measuring tool for the entire project, It will save a lot of time and frustration
  3. When cutting, measure one piece, cut, then measure the next. It helps to keep your pieces more even and accurate.
  4. It is helpful to paint and stain before cutting. Don't forget to do all the edges after you cut if you paint/stain before hand.
  5. When cutting grooves to provide roosting holds, I found that using a table saw is a good alternative to a router.
  6. When you attach the side pieces, make sure they are flush or slightly below the top edge of the back piece. This makes it easier to attach the roof. Also, make sure the side edges are flush against the back pieces edges, or your partition will not fit.
  7. When cutting spacers, set the table saw to seven-eighths inch
  8. Securely fasten the front upper and front lower pieces by putting screws in, don't just caulk them like the directions indicate in the four chamber plans
  9. I used one inch by six inch by six foot boards for spacers and sides, you can use the extra wood to make roof supports.
  10. The width of the spacer doesn't matter as long as it isn't too big. The height and length are what it really needs to be exact
  11. When putting the box together, dry fit the roof several times to check for gaps before moving too far ahead. This makes sure the roof fits the back properly
  12. Preserve your paint brushes by wrapping them in tin foil and sticking them in the fridge. 
  13. If you want to save money, check the "oops" cans at your local hardware store, I found both my paint and stain there.
