What kind of adhesives/solvents do you use to assemble the model Alex?
I use various types of CA, sometimes mixed. For example; a drop of medium and a drop of super thin on a defunct gents sapphire watch crystal. Mixed and applied with a fine stainless steel wire. The wire is sharpened to a chisel end (with a slight angle) and polished. The wire pickes up any where from a small amount to a large blob (takes a little practice) The chisel end places the CA right where I want it to go. Large seams it is dip, place, dip, place, etc. until I have the seam filled. It also allows me to tack things in place then go back and add fine fillets and fill small cracks nicely.
When the wire gets coated with dried CA, I shave it off with a sharp blade. Not scrape, but shave, this keeps the polished surface on the wire intact. I also use a razor blade to cut the dried CA off of the sapphire crystal. Super hard smooth surface, can't hardly scratch it. Works perfectly for holding a drop or 2 of CA for applying.
PM me and I will try and get some photos for you to see what and how this works.
