going to step up

Frodo,

I applaud your resourcefulness, in taking on this project.  I think it is a great way for someone with very limited funds (for the time being) to get a leather sewing machine that will stitch through some thick leather.  When reading down in the post, I was tending to agree with Gymnast that you would also need a speed reducer. However after watching Big Dog Forge's video and seeing the patcher operating without a speed reducer, I think you could go either way, but like you said, "try and see".

Regardless good for you for doing this! I look forward to your new thread covering your progress on the project.

Best of Luck,

Steve

Thanks for the encouragement,  

I love building stuff.

Using a BIG pulley is equivalent to using a reducer, only simpler to make! Ignoring the forging he did (which is not necessary and he obviously only did it because he could) the only possibly trick part is making a new shaft, unless you have a lathe.

Should be an interesting exercise Frodo.
