[SEL] Saw blade hammering

[Bill Brueck]

Thanks, Tom.  I'm uncertain whether you or Dave helped the most.  My
technique did improve a lot after Dave's advise to strike the saw with the
hammer, rather than the other way around.  Although I was making good
progress, the neighbors were complaining about noise.
