Pros : I have been using this oak framing stock for several years and find it an excellent finish to my large stained glass panels. The pre-finished nature of the wood makes staining and sealing a minor task. Since this is a quality hard wood I can miter cut and biscuit join the corners for a truly professional finish.
Cons : As will all natural wood products I do get an occasional piece that is less than "straight as a board". Slight deviations don't affect the framing effort since I don't usually need an entire six foot length for any one side. I did receive several unusable pieces once and Delphi immediately shipped me replacement pieces.
Other Thoughts : I tried creating my own wood framing on my table saw and even though this costs more the amount of time saved that could be spent on creating glass works makes it worth it.
