I’m breaking down 3 full sheets of plywood to make 8’ long French cleats.  I have a cabinet saw, but maneuvering full sheets of plywood is… undesirable.  My hope was to use my track saw to cut double-wide strips, then make a 45° rip down the middle on the table.

My worry is that if they aren’t perfectly straight from the track saw, they’re going to have issues following the fence when I put them on the table.  And if there’s error on each cut as I work my way down each board, it could compound and go to shit, especially because I don’t have a factory reference edge on any of the strips besides the first/last.

I don’t have a jointer, and while I would absolutely love to buy the festool megabeast track of glory, it feels hard to justify when I have two other potential options on the table.  Pun not intended.

What do you recommend?  An extra set of hands on the table, or do you guys have a secret for a flawless track connection?

Last thing I’ll mention - yeah, it’s shop furniture, but this is very much an aesthetic piece.  It’s going to be the focal point of my garage shop.  I’m using good wood and finishing it nicely.  What I’m getting at is “good enough for tool storage” is not what I’m shooting for here.

Can you (in practice) cut dead-straight with two joined sections of track?
