I compost on the very north west coast of Cal and we have very wet winters so my piles always turn cold and soggy. My bins are 4X4X4 and I have plywood covers for them to deflect some of the water. I don't worry about them until spring when I uncover them. If they are smelly I turn them and add fresh horse bedding from the public stables nearby and I may add some straw that I keep on hand.
I had the bins built of 1"x1" square tubing at a muffler shop and I wrapped them with 1"x1" mesh wire. We have a large yard and I take my composting serious. My First Wife mows about 15,000 sf of lawn that produces lots of clippings, plus I get 3 or 4 pickup loads of bedding and several bales of stray for 2 to 4 bins here and 2 bins at the Church where I am the chairman of the compose management one man team. Not much else I want to do at 74.
I used to fret about the coarseness of the compost as I uncovered it in the spring but I find once it gets oxygen it finishes in the soil in a couple of weeks after applying.
My compost piles are just free standing, no bins, and about 6'X4' long and wide and about 3 ft. high now. Once the weather warms up in about 2-3 weeks I was thinking of adding some cow manure and let it age in the compost. Is adding the manure a good idea? I can get all the fresh manure I need from a cattle auction site down the road for free but I know it needs to be aged some way before I can use it on my garden.
Good grief - I think you're doing plenty - for someone a heck of a lot younger than you.
Good for you!!!
