My Grandmother had a treadle sewing machine, which I liked to play with whenever I could sneak into her sewing room - and Grandpa had a big treadle grindstone, which no one ever played with !

Thank you, nqtronix, for your kind comments !

Our Workmate 200 dates back to around 1994. When fully open, the jaw opening is 5-7/16”. When the sawbuck crosses are clamped tight, the jaws are 5-3/16” apart.Reducing the width of the crosspieces would do the trick for you, but it probably will not need a full 1” taken off. Try say 1/4” at first, or experiment on a few scraps. Alternately, you could trim 5/16” off of one of the Workmate jaws (assuming it will still close up) , or decrease the 85° angle a little.

Thank you, Bill ! You are very kind !!

Thank you so much for making this Instructablel! .Today, Palm Sunday 2017, as soon as we returned from Holy Mass, I opened up your Instructable and folded up five nice little palm crosses. May we all have a blessed Easter !

Clever design !

Спасибо ! Ваш комментарий очень ценится. С наилучшими пожеланиями.

Thanks !

Would you cast the base with the bearing pillar and fulcrum pedestals as one piece? That would make it easy to finish; just drill two holes - and a little filing of course. The flywheel would probably be an easy casting and have a healthy moment of inertia. Would you make the lever and links of wood?

Thank you for making this Instructable ! Very well done and informative !

Yikes!! Just hooking up a 6 Volt battery pack is a good way to overwhelm the solar engine, but not a way to “test” it. The essential purpose of the solar engine is defeated. Best test it with the solar cell you are going to use with it! A battery source could be used for some testing, but only if a resistor is put in series to limit the current to the approximate level that a little solar cell would give. With only 2200uF storage, try a 10K resistor so that the cap will charge slowly enough for you to watch its voltage via a high impedance voltmeter across the cap leads. You’ll be able to observe the behavior of the circuit as the turn-on and turn-off voltages are reached. And double-check your circuit to make doubly sure that the wiring is correct and that the pola...

Great project... great work...and a great video !!!
