Here's a tutorial for you:
http://w3.enternet.hu/fscult/tsfs1.rarI've made it for my MODing mates a while ago.

It always works for me, I only use TS1 though.
Glueing in TS1 is very simple:
1) NEVER use glue as child !
2) always select the hull object first (with the object tool).
3) only then select the GLUE AS SIBLING !!! tool
4) click your pre-made turret combos one by one with the glue tool. (Do not touch the Hull with the glue tool !)
Done.
Making the turret combos (prior to glueing to hull):
1) Move base and barrel objects into position
2) Move the axis of both base and barrel into same position, preferably centered within the base object. Both the base and barrel will rotate around this point.
3) Use the Normalize Rotation tool for both axes.
4) Move a light into same position (just where the object axes are)
5) Select the light with the Object Tool
6) Select GLUE AS SIBLING tool
7) Click the turret parts in this order: Barrel > Base (Do not touch light with the glue tool)
Done.
Making multi-barrel object if you want one (prior to making turret combo):
1) Move all barrel objects into position
2) DO NOT use light
3) Select first barrel object with the Object Tool.
4) Select GLUE AS SIBLING tool
5) Click barrel objects one by one (except the first one)
Done.
Never tried this with other than TS1 to be honest.
