    Default Homemade Gear Cutting Hobb

    Had this emailed to me and found it interesting, enough that I'd put it here for the benefit of the newer Members and others. He used the Hobb to make a set of change gears for his lathe, hence the title.

    Thanks Michael, I didn't bother looking to see if anyone else had submitted something similar.

    Thanks for vid link Kryn, I am absolutely going to give that a go at some stage. I have made a spreadsheet and diagram for myself of all the angles and trig and measurements etc. I liked the simplicity of his "measure the tool before giving it a radius, then afterwards" to figure out how to alter plunge depth. So easy.

    Thanks again.
