Most antweight verts I see have a bulkhead which screws in next to the weapon and has a M3 thread, but where would I get one?

I don’t know if this is what you mean as your use of the word ‘bulkhead’ threw me off.
Do you mean this? It’s a prop adaptor and they normally come with the motor. You can buy them separately. I’ve never seen one sized for an 1806 come in M3, they’re normally M5 and will be either left or right handed (in that image, the caps are different colours to denote that)
I have thrown so many of them away over the years so someone might have one spare.
Apologies if this isn’t what you’re refering to.

That’s exactly what I meant, thanks. I tend to get mixed up with screw sizes.
