How to hold slin pins up when backfilling multiple

[vlf23]

I’m looking to backfill 7 slin pins at the same time, with several different oils evenly distributed between them.

How do I hold all the pins upright throughout this process, so the oil doesn’t spill out?

The best idea I have so far is to just tape them up against a wall, but does anyone have a more elegant solution?

You don’t need to backload anymore. They make detachable slin pin sized needles. Draw with a 23-27 and swap for the desired slin pin size after. So much easier than backloading.
