Jakobs Gear Hobber from scrap (no casting)

Recently I decided to build a machine to manufacture gears, in this video and in the next ones I will show the progress of the construction. I hope you like it. More videos coming soon

Very interesting.
What is the goal? ( I mean sizes of gears, types of workpieces etc. )

• using electronical gearing can help reducing mechanical complexity
• pure mechanical gearing has a certain fascination (is more fun to watch)

Are you already all the way through with the design? Tailstock support improves results quite a bit.

Someone who decided to go without any electronics, because .... he wants it like that.
This channel is full of good explanations and tips.



I went for a complete electronic approach. The gear axis has a ratio of 1:7 to increase torque a bit. The hob spindle is geared down 1:5 and runs at 600 rpm top speed.
