Hummmmm.... :dremel: Seems like a great substitute for a power hacksaw! Could be very tempted to try this one in the near future as my power hacksaw is currently my right arm! I can`t see how it is getting the pressure downfeed. I guess the vertical powerfeed would just be too quick at its lowest setting and the blade would need to fall at its own pace. I have to admit, I haven`t really looked into power hacksaws so I don`t know how they control the down feed.

Darren:
Perhaps the clapper falling down gives the down feed? I'm not sure but it might work?

John Hill:
Yes Darren it certainly looks like he has it mounted on the clapper. 

The one that Nevil Shute made is shown here http://www.nevilshute.org/Engineering/ModelEngineer/convertingshaper1.php  I rather like that story as he had a petite little machine like my "Sally Shaper".

Most usually they are gravity fed, assisted by additional weight(s) placed on the end of the saw arm.
