Never violate this rule. If you are trying to work on your Ferret project while babysitting, the child will get start crying inconsolably at the very moment your hands are fantastically filthy. The child will invariably chip away with it on an exposed, painted surface. Count to ten while formulating an appropriate response. Some tools that are made in China actually work and will serve the occasional Ferret restorer well.
Ferret owners keep their favorite tools in places of honor.
Where rust is an issue repairing it is a pain in the ass. It may be enough to quell the urge, thereby saving you thousands and allowing your children to go to college someday. Otherwise, you could call it a good start and besides, having Ferret parts laying about really impresses some folks. Before you do anything try to determine if this conversation is divine guidance or is simply the work of Satan. An Ferret that is disassembled takes up ten to fifteen times more space than an assembled Ferret.
