Well, mine is also not the strongest, but for the kind of boards I
make it's sufficient. I bought fairly huge copper clad material from
Bungard which I cut with this saw. Works fine if you take some time
and don't get impatient. Since I use ~60 boards a year that's no
problem for me. I figure those doing fewer boards will find the saw
quite handy.

Hmm, I haven't disasembled it yet so I don't know.

So far no need for this on my end yet. That said I'm still busy enough
with my other projects :-))
