English to Spanish Tech/Engineering Architecture buiding with SIPs (paneles estructurales aislantes)

Hola es un texto sobre como hacer entradas de 45 grados en construcciones con PEAS. El texto dice así:
If I am building a 45 degree bay, then I miter-rip the four affected corners to 45 degrees to form the inside a outside corners. The key ot a tight assembly is rip the splines at 45 degrees out of 2x materials and glue and nail these assemblies together before fitting and raising the pieces.
Gracias!!!!
