Asdaq....that is the unfinished 510 end
The bottom is still undetermined both length of tube and button....the caravela approach is slick but requires reverse cut threads and that's more work than I'm looking to do. I have an idea using magnets to hold the button in the fire and lock position...headed into hobby lobby to see if I can find some small and strong enough
Does the caravela actually have reverse cut threads? Does the GG? It doesn't seem so necessary as you can vary the degree of tightening like with tools or by finger strength.
