Retratable internal external screw cutting tool videos

[thehomeengineer]

Hi All
Finally cut some threads with the retractable tool I have been working on for the last month or so. There are two videos one cutting an internal thread (M16x2) and the other cutting an external thread (M8x1.25). (This second video also shows my back stop being used)

Overall, I am pleased with design and the first cut threads, with only a few minor tweaks to the design needed to improve it.(I am sure there will be other improvement/comments from the knowledgeable HMT members, which I look forward to). I could do with a surface grinder to finish it off nicely but unfortunately, I don’t have one or access to one. The project was mostly made from recycled materials.

If anyone could also recommend a free video editing package/app that a complete novice could use I would be very grateful. I do apologies for the poor camera work but I am sure you will get the idea on how the tool works.
