Holding connectors for soldering... Any tips

I was going to start my enclosure for my electronics and I was wondering if anyone had any tips on soldering aviation connectors. I would think I need to put hem in a vice to hold it while soldering?

A small soldering vice is what you need.

or perhaps just a helping hand

Failing that, a woodworking or metal vice will do the job

i just hold it inplace with some double sided tape. Has worked extremely well for me
