Dan, I have cut slats to the same size by bungeeing a bunch of them together then cutting them all at once. I used a circular saw, a sawzall would be like watching me try to weld, which means it would look like a four year old did it. If you have carpenter buddies, then definitely who wouldn't make a few cuts for you especially if you showed up with beer and say I don't know, barbecue?
Yeah I know. Knowing my friends, if I have a plan and it just needs to be executed on they'll be happy to help.Lol Dan. Seriously, if you lived by me I would definitely help you make those slats.
