i hold and squeeze the coil in pliers and blowtorch the life out of it - for no other reason than i like it! I use tougher wire than you usually so it's a method that i find gives me consistent coils without the gaps, although there's really no need to panic about it. A few gaps will not ruin a coil, but hotlegs/hotspots will need to be sorted, usually by nudging them about a bit.
I use a jeweller's screwdriver to do this and i can be fairly ruthless with it. And then re-tighten the screws - SXD does this religiously in all his videos. I don't use microcoils but the advice is good.
There are a few jigs out there - i seee on from Qvapes that looks like A Darkzero rip off, and i have a DZ jig for my stuff. There is also an ingenious one made by Turbocad6 that you can find on Youtube.
Best of luck.
