I was given my first set of real tools at the age of 4 and it's been down hill since. what they haven't been able to sew back on has been able to grow back... so far...
funny thing is I could have saved myself a lot of trouble had I just ordered the sprockets bored to size with the keyway already in them. it was a 4 week lead time and 4 times the price. a real no brainer there
The reciprocal cut of die filer is aided with a hold-down; an overarm maintaining light contact with part. Some use a spring and roller, others a finger or ski shaped leaf spring bearing down with light pressure, while you maintain the feed rate.
...we'll learn more by wandering than searching...
I found that making 2 cuts at just under the finished keyway width then slicing out the remainder from between them worked very well. then I finished the keyway with a small file. I always try to make my keyways as near to dimensionally true as possible.
Even when I has a broaching machine I would finish the cuts with a file. I have made a statement before about files. I love them and they hate me. New files get treated like precision instruments old dull files become scrapers or knives I can mill a head or deck an engine block and set the fit of a V8 intake manifold with a large file to almost the same precision as a CNC mill or surface grinder it just takes me a while longer.
