I have soldered to Gargraves-a task I do not relish even with catsup and mustard
and I have used the Gargraves power connections-the 911-1 Solder-less connectors.
They are a pain to install but electrically I find that they are sufficient to the task, and easier to use than soldering
And I have found that if you take a spare wooden tie, and set the connector on it, after aligning the tab into the rail slot-and using a small “persuader”...one solid tap drives the tab into the slot, and then sliding the rails closer to the connector makes a useful mechanical connection.
The drill idea has merit.
But I’d rather take a few minutes to get power to the rails than spend a frustrating 5-15 minutes soldering with all it entails.

to each their own
