The only problem with making things is new tools cost
10x more than the
item you are making.
And the tools/test gear you need to repair classic computers easily costs
10* the cost of that classic (or indeed the cost of a modern PC +
emulator for said classic machine).
So? Those tools (assuming you buy good-qulaity ones) will last for many,
many repairs, woodwork projects, or whatever. I can't remember the last
time I had to replace a tool because it was worn out (other than things
like hacksaw blades, of course). Good tools will outlast you and me :-)
You are speaking to a person, BTW, who finally decided to buy a good
engineer's lathe in order to make a replacement part for a device that
cost a lot less than 1/10th the cost of that lathe. The manugactuers of
the device were playing protecitonist games (they would only supply parts
ot authorised service agents), and there is nothing more likely to
convince me to make the part myself. Of course the lathe has been very
useful for all sorts of other work (and will be in the future).
