.... Did you stage your miter cuts so all the parts that must be the same length are cut at the same time?
..... spline all those miters! 🤠

Yes... all miters stages and cut at same time. 
I could have done hidden splines but didn’t. Didn't really want to do outside splines because burning would likely expose them. I could come back and do vertical dowels but at this point ...nah!
