I had to assemble the pieces on the ends that go in the middle of the channel. Then they're clamped and match drilled.
When it was time to rivet, I had a significant problem with the 4-8 Cherry Max rivets. Van's says the recommended pop riveter won't work (that's correct) but suggested you don't need to buy the expensive Cherry pop riveter because any Home Depot like pop riveter will work as long as the stem isn't anything but straight. That's wrong; at least it was for me.
I eventually got all 12 rivets on one side done, but with stems breaking prematurely and drilling out the head, I went through the full 26 supply Van's sends.
They're expensive things. $1 each from Van's which didn't have them listed on the website when I looked. So I had to order 100 of them at SkyGeek at 69 cents. Oh, and a new Cherry pop riveter from Aircraft Spruce.
