Hello everyone!

I've read some tips on using greenstuff - some lube to keep it from sticking, sculpting tools, how to make it wavy and other things...

I need to make a couple of buzzsaws for deffkoptas. My choices are either to try making them out of plasticard, or to sculpt them in greenstuff. If I'm going to do it in Greenstuff, presume I make a ball of it, flatten it out....should I go at cutting it into shape immediately, or should I let it set for a while to get semi-firm? And if I should wait, for how long?

I suggest plasticard. Draw two circles, one inside the other, to demark the top and bottom of the "teeth". Divide the circle along the diameter like a pizza pie till you have enough teeth marked out. Draw the detail of the teeth and cut them out (but not off of the inner circle).

Agreed. If you want you can go back and add more detail with greenstuff later, but it's not a good material for the base construction.

Don't overlook the fact you can GS and plasticard, but yeah for this Id go plasticard.
