I've just bought a Kennedy hacksaw and I'm trying to cut with it and I
need some advice.
When I got the saw I couldn't lift the arm up and I dismantled it to
discover the damper was stuck. I can't assemble so it doesn't stick.
I'm very puzzled as I assume it must have worked in the past. The rod
to the damper changes angle as the blade falls and to compensate for
this the damper piston is barrel shaped - presumably so that it will
work at different angles. I suppose this ought to be a slice of a
sphere. I've measured the dashpot bore as well as I can at 31.61mm. If
I measure the piston across the worn strip in the middle I get 31.58mm.
If I measure the piston across another diameter of the spherical slice
then I get 31.73mm. It's not very worn - in fact visible wear has
increased noticeably with my mucking about. Does anyone know what is
going on here?
This is the model where you supplied your own motor and the one I got
with it is immensely heavy - does anyone know what was recommended?
Does anyone have a manual that they would be prepared to copy/scan for
I'd be grateful for any suggestions.
