I've got metal files (i think 3 sets of different sizes), apoxy, and about 4 manual pin vices
It's just that every time I do a metal it seems to cause problems
(I love flamers of tzeentch* for example but their arms are hold on by a pin head sized joint).
The hounds were an extreme example, as the heads had their joint squished quite a lot one way, whilst the receiving part on the body was squished at 90 degrees - it took hours of careful filing to get them to fit, then pinning and greenstuf to actually get them to stay on
I've actually got a cordless dremel clone now, along with welding gloves** and a handy dandy vice thing (intended for holding irregular shaped bits of wood), which make life a little easier.
*Especially as the last time I played them a friend had been going through all his opponents like butter with his seraphim + sisters armed with flamer, he got the first shot in with zero kills, then got about 30 wound rolls on 5 models when it was my turn
**Very handy when using a dremel to drill holes for pinning (metal gets hot when exposed to friction, who'da thunk it).
