Yes, that jig has been around a while. While cheaper than a grinder, it certainly is more expensive than any other round file filing jig. Also, unlike some round filing jigs, you can’t change the angles. The ATOP jig has angles closer to a race chain, not a work chain, if it matters to you.
When I got prototype to test out before being sold to baileys, you got 3 sets of rollers. Angles can be changed and if you have just one set using electric type tape lets you change them too.
Also if you experiment with 6 sided square file you can change things again. Guy north of me used to make some nice chain using that for work.
I got to where I could file a work chain pretty quick with them.
Also tried my hand with a play chain. It did pretty good in chain build off 3rd if I recall right and 2 stock saw 3120 races with 2 1st.
Best way to learn is free hand though. I just never had patience. But did do free hand on 325 and 3/8LP
