Having neuropathy fingers I found using a short piece of electrical tape for holding a drop wire in place for setting up a connection to a buss to be very helpful. Whether crimping, clamping, lever nuts or soldering.
I find Wago lever nuts great for wire ends when the wires may need to be reoriented. Quick'n easy $.30 to $.70+ each depending on quantity purchased. Time is money.
Incidentlly, I flame solder most solderless terminals. I prefer the solderless terminals because of the insulated sleeve.
To flame solder a crimped end, position the wire and terminal end free from an immediate combustable, hold the flame directed away from the end of the terminal but just touching the side of the very end with the flame. You will notice a glazing flowing from the tip down to the crimped portion. Just touch a thin piece of solder to it. Done.
A similar thing can be done with an iron, just a tad trickier for me.
Do not solder a screwed down connected terminal. You can damage the plastic base.
Hint, when pulling a wire to be used as a buss consider cutting a hand full of short pieces of shrink tubing and slide them along the installed buss wire for future attachment points.
Soldering might sound cumbersome but I learned it from an electrician I hired to wire a layout decades ago. He worked like a sewing machine knocking out the job in half the time I would have taken.
One of his tricks was using a thumb actuated Bernzomatic. Thumb on flame on, thumb off flame off.
Never had a wire come loose since soldering.
If you are a little skittish on soldering grab a good iron or torch, pick on some wire scraps, click around U-Tube and ask some questions on board here.
After some bubble gum sloppy initial attempts you can become very comfortable. Just give yourself the freedom to fail at first. Read, watch, ask, learn. Once you understand the concept you will be on your way.
