Hard on sanding disks but easy on me. You might want to rough cut the angles to save wear and tear but I would not.

Even doing it this way, set up is critical. The Main Table needs to be absolutely square with the face of the sanding disk. I believe you can rely on the v120 to give you the proper angle.

Lock the v120 in the miter track, clamp the work piece to the face of the v120 and use the quill to advance the sanding disk into the work piece.

That got me wondering about glue joints. Would there be a difference on a miter joint if it was sanded or cut? With the 22.5 pieces, the glue joint can be a bit tricky; opening up so much grain. Would a sanded surface offer a better or worse surface to accept glue?

Presume that each surface is well cleaned, tack cloth, etc..

Anyone know or have a source? Frankly, if the sanded surface was a better surface, I would be willing to change my construction methods for flag cases.

Be well,

If it were for a normal size flag it wouldn't be too much of a problem, but this is for a "Post" Flag (approx 10'x18'). The flag was flown over the military installation that I work on and was recently retired (replaced). It's going to be presented to the deputy to the commanding general when he retires at the end of the month, he will then turn around and donate it to the post museum where it will be put on display, so I need to do a good job.
I'm using oak 1 x 4. The top 45 degree angles are not a problem but I'm not sure of the best way to cut the 22.5 degree angles for the bottom corners.
I made a jig of sorts by cutting a 22.5 degree block on my miter saw and attached it to the SS miter gauge set at 45 degrees and screwed a piece of pine to it for a fence. I thought this would work but I cannot cut all the way through 4" stock. Thought I might cut as far as the blade will reach and finish the last inch or so with a handsaw. But now I'm thinking maybe I could use the same jig and make the cuts on my bandsaw instead. If I use the bandsaw will I need to adjust my angle to account for drift or should it be ok on a relatively short cut?
Or is there a better way to make this cut that escapes me? What would you do?

Looks like they recommend "smooth" vs "rough", as long as "burnished" is not taken for smooth. Sanding to 200 seems to count as "smooth."

Before I forget, you might want to consider what type of glass you will use. When I can afford it I use a "conservator" framing type glass. It has UV protection to protect the flag and some styles have a matte finish which allows the flag to shine through very well, with little reflection from outside lights. To be honest it can add significant costs to the finished piece, especially if you are donating all materials.
