Main Gun Barrels Phase 2
The main guns require a lot of stepping down from reinforced breach to barrel thickness otherwise the base looks too spindly. This is the best method I have come up with and it's rather simple and effective. Since all the reinforcements are not of the same thickness I vary between 0.040 tubing thickness and 0.020 sheet styrene for the different step downs which seems to add a bit of panache.;)

Once the sheet styrene is fully glued around the barrel the tailing can be trimmed off. It is advisable to leave a long tailing on the wrap until the final gluing so you don't end up with a flat ridge at the seam.
