Sculpting, Shaping, Cutting, Drilling...
This is a pic of the "dremmel tool" I use. There are
brands. Available so check 'em out if you're serious about doin' some
good Transformers (or any toy for that matter) Altering!
These are just some of the tips available which I regularly use.
are great for sculpting and enable me to do some very detailed/fine
cutting and shaping that I couldn't do without 'em.
