Okay, good to know, but all my files cut on the push stroke. Don't know that I've ever seen one that didn't.
It seems as if your making my point,tang on top, being pulled downward into the work.
My apologies then Bruce, but from your video it actually appears that you have a common rattail file mounted with the tapered end pointing up (see video at 1:14 - 1:18) and the tang mounted under the table in the drive collet (see video at 2:08), though in motion and blurred.
Please excuse my incorrect observations and assumptions!
Certainly not an issue, I think our terminology got misunderstood, the tang (handle end) is on top, being pulled downward into the work, there is no taper on this file, it's the only file I had on hand that would (kinda) work in the moment. Per blondihacks videos, I'll make an assortment of files over time & since this die filer has the spring loaded over arm & I can clamp hack saw blades, abrasive stones & lapping sticks.
