build expander/countersink drill bit (video)

[Demy]

Hello community, inspired by this post https://homedistiller.org/forum/viewtop ... =2&t=80331 I decided to build some bits for some simple jobs. I have few tools so I can't do cool things ..... instead of inserting lots of photos I thought I'd upload a vodeo on youtube. I hope it helps the community otherwise .... you can fool me !!!! Hello.

Quite the innovator Sir. Could a little machine oil help with some of the forming?
BTW, I still have a scar on the top of my foot from soldering pipe with sandals (sandalo) on.

Sandals ... not the most suitable shoes. I made this realization on the fly, it was a test but it was successful, only a weld point ... but I know that burning pain !! Usually we use the lubricant for drilling but I have not tried with this job, maybe it works or maybe it reduces the friction too much and therefore does not deform the metal. Something to try.

Thanks a lot. It is also thanks to you that you triggered the "spring" with the initial post. For maximum accuracy I originally posted the link to the discussion.
