    Default A scroll saw from Sweden - Ejca

    I owned a Hegner Multicut 1 for a while and although a lovely saw, It lacked the table size for many projects I wanted to undertake. Since I live in Scandinavia now, I figured I would start scouring the local market and see what is available. Anyway, I came across this beauty:

    It has a 3 phase motor (not sure of the power but at a glance it looks like at least a half HP) and a cast iron table, frame and arm. These machines were built in Sweden's industrial heyday and like everything else of decent quality, have gone the way of the wooly mammoth.

    I am struggling for room at the moment but have plans on extending the garage next summer. For $500 it seems like a decent purchase - even if I have to mothball it until I have the space.

    I thought you guys might enjoy seeing a machine from across the pond.

    Paul.

    Looks like a great tool, thanks for showing, but how exactly does it work, the top arm looks solid and Fixed? How does it articulate ?
    Cheers

    Hello Arron,

    my guess is that there is a spring in the blade fixture assembly of the top arm. This provides tension on the blade and the motion is provided by a wheel under the table to which the lower blade fixture is attached and pivots from. Here is a picture of a similar machine minus the cover and motor:

    This would likely result in less vibration as the heavy arm does not have to reciprocate. This also means that speed changes can be accomplished via pulleys and belts (although I would like to use a VFD). It seems like a different design approach to the same problem where the Swedes took a "Wenkel engine" design and the Germans went with a conventional "piston engine" route.

    Paul.
