steve104 Posted September 5, 2015 Report Share Posted September 5, 2015 Bought two singer sewing machine treadle bases. Want to use one to make a foot powered scroll saw. Have seen a few planes ( just pics of most ). Anyone have a good plan for a wooden scroll saw? Bought blade clamps from Hawk and a 5/8 " shaft with two bearings to attach a pulley for the the treadle wheel. Just need a basic plan w/measurements. Need idea for the off set wheel to attach rod to lower arm of saw............Steve amazingkevin 1 Quote Link to comment Share on other sites More sharing options...
crupiea Posted September 5, 2015 Report Share Posted September 5, 2015 Make you think dont it? Seems you would need to somehow attach the treadle to the lower arm of a scrollsaw or what would be your saw. You can see from a normal powered saw that if you push on the top arm the bottom one will work because of the mechanism in the back that hooks it all together. i suppose you could just make a stripped out version of that easy enough or convert an old junker. My concern would that when you use a treadle in a sewing machine there is a bit of stored energy there due to the way it works so one pump doesnt mean one stroke of the sewing machine. One stroke will last for quite a few up and down repetitions due to the balance wheel controlling things in a way. The scroll saw would be a direct drive where one pump down is one down stroke, release, one stroke up. The speed would be pretty slow to actually cut anything. of course this can be figured out somehow. I wish you the best on it sounds like a fun project. heppnerguy 1 Quote Link to comment Share on other sites More sharing options...
steve104 Posted September 6, 2015 Author Report Share Posted September 6, 2015 Thanks San Diego for encouragement. I will have to do some calculations on pulley size to determine speed ratio between the treadle wheel and concentric wheel connecting to the saws lower arm. I do have some ideas for the design of the saw. The treadle frames are in perfect condition. They look almost new. I will post pics when I finish it. They deliver our building next Friday, and will be erected the next week. It will be a few weeks to insulate, install AC and electrical. Then we can move all the woodworking tools in and start working again......Steve heppnerguy 1 Quote Link to comment Share on other sites More sharing options...

heppnerguy Posted September 6, 2015 Report Share Posted September 6, 2015 An amazing effort to take on, making a wooden scrollsaw. the video that Larry posted is one that is worth looking at even if you have no desire to ever try making a wooden scrollsaw yourself. It is amazing to watch Dick heppnerguy oneleggimp 1 Quote Link to comment Share on other sites More sharing options...
WayneMahler Posted September 6, 2015 Report Share Posted September 6, 2015 I remember seeing plans for a velocipede. Scrollsaw works like riding a bike. A friend of mine in Duluth Georgia made one. I'll write him and ask him where he got the plans. That might help out with some of the mechanics. Quote Link to comment Share on other sites More sharing options...
DWSUDEKUM Posted September 6, 2015 Report Share Posted September 6, 2015 I purchased a good one from Rick Hutcheson's web site - http://www.scrollsaws.com/ On the left side if the page is a collum scroll down towards the bottom and you will see " Foot Scrollsaw" He has two verstions a pedal version and a treadle version.

Fish Posted September 6, 2015 Report Share Posted September 6, 2015 There is a plan in the last pages of one of Patrick spielmans books. I like the bicycle idea. Quote Link to comment Share on other sites More sharing options...
