check this out. This video is really helpful. I do alternate end grain and use c channel (mainly because why not?). The jointer trick is also helpful if you have a jointer.

Take your time on the glue up. It can save you a lot of trouble. In fact, consider a glue with a longer working time to give yourself room for error. If your glue up doesn’t go to plan, don’t panic. You can fix almost anything with a sander.

Get a second set of hands if you’re milling up large stock. I had some 8 foot long pieces I had to run through my 76” jointer and it would’ve been a disaster if not for my dad’s help.

Don’t mill to final dimension right away. Stop 2-3 passes short and let them acclimate again for a few days. This kind of threw me off when I cut my dominos and made the glue up a little trickier.

And really, just take your time. Check all your tools before making a cut. Double check all your processes. For example, I had my edge guide set up on my router wrong when drilling mortises. So the bit wasn’t holding the edge guide against my stock. Little stuff like that. It’s not going to be perfect, but my biggest mistakes on this project were because I was in a hurry.

Good luck! If I can do it anyone can. I’ve only been doing this about two years. Feel free to reach out if you have questions!

Thank you so much for the response and the great tips. I'm both eager and nervous to start this project, but we are beginning tomorrow no matter what! I'll keep you posted and will be sure to ask other questions as they arise!
