I also started a woodworking project. I'm making a Burial Flag Display for my Texas girlie (her Uncle's flag).
I have it tentatively designed like my Father's burial flag...
My illness and weather has set that schedule back by a bunch. That and 4 cuts I have to make. 4 22.5 inch degree angle cuts.
Note that the bottom angle cuts in my father's case are 45'd on the body of the case and trim was added in the front to look like 22.5 degree cuts. I'm sure it was done that way for production purposes. That's not how I want to do it.
I have tried every which way to do it with my Festool TS75 and there just is no way. I puzzled that out for days. It either has to be cut by hand (which I am going to try on some test pieces) or on a table saw....a table saw that I don't own. I can use my brother's saw (it's still here just by happenstance - he will move it at some point in the future, maybe Spring) but even then I'll have to build a Tenoning Jig to make the 4 22.5 degree cuts.
I have rough-cut to length the piece I'm going to use (Red Oak, of course!

I'd like to make it continuous grain on 2 of the upper visible sides. No one will ever notice it, probably...but I'd like to try.
I rough-cut the length of Red Oak and S4S'd (surfaced 4 sides) is and and ensured it is square

It was quite a treat processing the wood in this Residential Woodshop!
