When we did ours, we froze it in the more primal hunks and then used a band saw for the "intricate" cuts (like the loins we froze in one long piece, then cut with the band saw into chops) - SO much easier that way! I too vetoed the scalding part - I choose instead to focus on turning stuff into tamales and sausage
We did however freeze the skin in chunks for the dogs to chew on and gave them the feet and the ears - no one felt like messing with that when it came down to it - but the dogs LOVED us for it!
Plan several days around it - one for butchering, one for making sausage with trimmings...we did one day making tamales too...it's a time consuming thing beyond belief! But it's the best pork EVER! I had the added bonus of my husbands knowledge from doing this growing up - see if you can find someone local to come help that knows what they are doing - maybe trade them out some of the meat for their time? That way when you get to the next one, you'll be all set! Plus, the extra pair of hands REALLY helps!
OH! And ribs that haven't been trimmed down to nothing are the best! Just remember to cut them into manageable portions
Like, cut in half lengthwise...as a joke, my husband left one rack whole...then we cooked them up for my friends birthday party - I wish I had gotten pictures of my 7 yr old 'niece' eating her "jurassic ribs!" It looked like a scene out of the Flintstones! But yeah, we season the ribs and cover them in sliced onions, bake 'em a few hours real low and slow at like 250 degrees...then toss over the BBQ coals with sauce just to crisp up a little and add that BBQ flavor and they are the BEST ever!
Good luck with it! It's not that hard to figure out - just very labor intensive!
