Alternate round files ,,, recent discovery

[Kamusur]

Hello to all members and guests and may the mods move this post should they wish

I am not what you would call a prolific poster nor have i been around here much, lately.
But a few months back i made a discovery thus and thought i would post it for shits and giggles,, "bolts, threaded rods, and screws" can also be used as inside circle files ie round files. I have used them on timber solid and ply, Hardiplank, masonite, gyprock and cement sheeting. Also on surfboard deck rocker in the nose area and for foilng fins. They are also cheap lols. i haven't bothered to photo them because they are self explanatory. .So good luck to those who try em.

Assuming what you discovered being self-explanatory may be an overreach:?
