The first of a series of group shots for you tonight.
This is a mixture of older metal figures, and the more recent plastics.
Ironically, the metal figures are easier to prep and deal with.
I think it has more to do with the combination plastic/resin mix, which can definitely pose more challenges than a hunk of pewter. :-)
Since I've been doing this for a while, I am very used to dealing with very heavy metal figures, as well as more dainty versions. I think I have at least 4 pin vises, along with many drill bits.
Also, the use of green stuff in the gluing process helps a lot. Basically, a blob of green stuff is sandwiched between two layers of super glue. This adds a lot more stability to the joint, as the green stuff fills in the gaps which are bound to occur.
There is also a bit of a chemical reaction between them, which solidifies the green stuff into hard crystals.
This method is very handy when trying to attack two pieces that are too difficult or even impossible to pin.
