Here is the link on Pedro's site for the Wiseman coffer. The wise men coffer, scroll saw fretwork pattern (finescrollsaw.com)
You can see that different types of wood were used. BBPW would definitely be a lot cheaper. If you decide to make this there are a few tips. The sides are intersecting slots and depending on the wood you use, the outer edges can be fragile. I left a 1/4" connector at the top to hold it all together and then cut them when I was ready to assemble. The top can be a little confusing. The drawing calls out a 18 and 25 degree angle. the 18 is for the short sides and since it's 1/8" I used my disc/belt sander with the plate on the disk sander set to the angle. I used my scroll saw set to the 25 on the long pieces. What threw me was I assumed that those pieces would butt up against the top and bottom edges. The side angles didn't line up! Once I looked at other samples I realized that the top of the pieces sit about 1/4" below the top and all the angles lined up.
Go figure!
