Bought the Flat packs and ran into some trouble with the first cabinet during install. Tried to build it all in one day, and had some issues getting everything to slide together right.
2nd one, I broke all sharp edges where bracing interacts, with a hand plane, maybe 1/32. Built the top inner brace section only, attached the back, on day 1. Let that sit and harden fully clamped and triple checking square. Then Day two got the rest of the lower bracing, sides and top on much easier than trying to do it all day once.
Any other tips?
Ordered a second left

. And have the cross overs started.
