Sounds like you've got your work cut out for you, Zombie - continually inclement weather and a busy commercial season in a little under a month to get ready for.
You're really not going to get any rest, particularly with the shoveling end of things in the greenhouse.
Unless you can find some way to make it so that, even if it snows considerably, stuff is safeguarded enough that you can let it sit a while, the extra daily workout is going to be a given in your fitness regimen for the season.
Yep, the inside of the greenhouse already shows a significant difference given your intervention, Zombie.
Your explanation also makes the big picture of what - safely - putting in a new top really requires. Numerous things need to come together just right not to waste the effort (and potentially run into more expenses), so I now get why it makes sense to wait it out.
I hope you get a suitable break with the weather so those makeshift repairs with what's left of the old top you mention can be done.
If not, you might perhaps consider instead some temporary way to cover those tabletops to better shield them from the elements.
Uniform across the board, Zombie maintains, here, there - everywhere - of his own accord!
Evenly coated boards you've got there. They do still come across as sort of orangey to me but that's to be covered with red, so the only downside is probably an upside as well: whenever the red eventually starts peeling/chipping away it will be promptly noticeable because the orange will shine through.
Cyndi Lauper would be proud you so let us see your true colours.
A sensible selection process you've got going there, Zombie.
Simply hoarding everything and clogging your entire house is obviously not going to yield useful results - beyond having your neighbours think you've lost it and thusly not annoying you with requests of tool lending anymore that is.
In truth we're pretty much spoiled rotten this day and age, when you can simply waltz down to a hardware store and get pretty much everything you could possibly need for quite cheap.
For context: my late grandfather was born in 1911 in the rural far north of the country and, as he often recalled, he had to walk several miles barefoot to school daily, snow or no snow. Shoes were terribly expensive and he had 11 siblings. Also, back then, if you needed something done (for domestic improvement or agricultural development) you either made it yourself from what you had or resorted to someone who could make it basically from scratch, like an actual blacksmith, for a price.
It's just crazy how good and abundant things are today. Still no excuse to be wasteful and not heed such wise advice as, essentially, always make the best from what you happen to have around.
The issue you ran into with the small machine screw is a common enough occurrence, Zombie.
We somehow seemingly always run across some makeshift past remedial solution, of our own or of others' devising, in the process of doing something else and which, incidentally, makes things hinge on those adjustments.
Furthermore, I recognise another of your good practices as something a grandfather of mine frequently advised: save whatever may seem useless today and it will prove its usefulness tomorrow!
As for the event at the paint store, I guess your proficiency in these affairs will only grow, so you'll be even more of a pro by the time you do go.
