    Hi Flint

    The saw was out and about last weekend at a Meccano club meeting where it was sawing the soft aero-modelling plywood I mentioned a while back with ease. The consensus among my engineer friends was that as long as it wasn't just balsa wood, it was a "proper" saw.

    I am not sure what other details to give. The blade clamps pivot and the arrangmeent at the rear of the arms is a turnbuckle which produces the tension. I find that although the arms can wobble from side to side a lot, it doesn't matter greatly as the kerf holds the blade true and in any case, with any saw the blade bends more than you should be pushing it. It does bind quite easily but if you stop and pull back into the kerf a little then it mostly frees itself.

    It still needs to be given a more solid frame and base so as to minimise vibration and allow me to run the motor at full power. Then we will really see what sort of muscle $5 will buy in Taiwan these days...

    Chris hasn't got a site AFAIK but you could send him a private message on here, Flint. Just search for Chrispuzzle in the member list.

    You could also check out ChrisPuzzles meccano saw with a similar principle

    The saw that Rick has plans for could easily be modified if it was required.
    I can't comment if it needs any mods, I have never built it.[/QUOTE]

    I have an old treadle sewing machine that will someday be a saw.
    As for the arms, I have several articles where they use BBPly for that.
    One of which uses an inverted T shape for the arms.
    Both sections of the T made of the ply.
    This looks like a stable approach. Of course there will always be some flex in the arms but I think a simple T beam or I beam construction would minimize that without adding too much mass.

    Thanks for the advise. Didn't think about using fruit wood for the arms of the saw. Will keep you posted as to my progress. Thanks again for your help

    I purchased the same plans but have yet to start making it. With Spring right around the corner I hope to have this project well underway! Please keep us posted on your progress and best of luck!

    Wooden fish:

    I have been active on this forum for several years, and I just don't recall anyone on this forum reporting any progress they had with doing Rick's foot pedal powered scroll saw.

    I recall on another scroll saw site some one commented on they tried to make one, but I don't remember much else.

    I trust you know that the arms should be made from fruit wood, like apple, pear, or peach wood. Any wood that has a lot of weight (from fruit or nuts) that the tree must support and the branches bend under the weight from.

    Great attraction to craft show booths I have read. Best of luck.

    Foot powered scroll saw

    Have enjoyed reading the posts. Have not posted earlier. Have been scrolling about 7 years. I do mostly 3D ornamentsand fret music boxes. Have purchased Rick Hutchesons foot powered scroll saw pattern - any suggestions or tips on making this a successful project. Thanks
