Nice to see a beater back again. Hope this one survives a bit longer!
Just out of interest, where did you get your one-way bearing from?

I'm also not too sure how it all fits together; have had a look at a few online articles and the picture of yours but I'm struggling to visualise incorporating a timing pulley into it yet still managing to secure the whole setup on a motor shaft
