Prepare & Install Horizontal Top Rails

has to be tackled right now i couldn't get a 16 footer so these come out to be about 10 feet i need them a few inches longer best way i figured how that stuff works is if you miter this 30 degrees or 45 and the connected two together then you actually that's loud you can have enough room to actually put wood filler and make it look like one uniform piece anytime you have exposed like this is the end grain part of you know the trim that everybody will see do yourself a favor grab either 120 sandpaper or if you really want to be bougie just grab a 3 8 round over router bit and then round it over it looks so undone you know if it's just a straight clean cut like that and people are seeing it so just round it over make it blend you know i just screwed up on the order of operation here this was supposed to be the top cap and of course i screwed up on it because i was like oh i didn't get enough lumber that's because that wasn't supposed to go there so what was supposed to go here is a six inch and then that on top but of course i didn't do that i think i'll put the six inch and then put another cap on
