360 - mini hypnodisc

[Eventorizon]

scorpion HK4025-890KV on 6s;

originally it had two 30 size 1400kv motors, never worked reliably.... when it was filmed on gadgetshow it was only running on 1 small 30 size motor on 4s!...

So that line in the show about it working perfectly wasn't entirely true At least the end of the sentence was right!

After not being able to find a supplier of brass gears, and having a boring day I decided to make my own with files and a lathe as a challenge;

Turned gear blank made from bronze;


1/4 of the teeth done here... Very boring work;


A few blisters from a needle file later gives this;


After a tidy up and some greese, in it goes;


Just one more to do and I'll be happy

Most bored people just sit and play Xbox or something. You go and make some precision brass gears from scratch by hand. Crazy person :shock:

Seriously impressive. Most of us would end up with off-centre gears and wonky teeth if we tried that. Did you just use the plastic ones for reference to get your spacing and such spot on?

[Mouldy]

Both my xbox remotes are broke lol

I'll take a few pictures when i make the 2nd to show how its done

[blazerbotics]

A decent shaft for those and your away

[Kenny]

Awesome that!

[PJ-27]

How long did that take!? Very impressive though.

[Mouldy]

Little guide;

Mount gear and blank on original shaft next to each other and mark out root diameter of teeth;


Hacksaw each tooth using original gear as guide down to root marking;


File with a needle file tooth profile again using original gear as guide;


Repeat until will to live has gone completely, then tidy up with emery cloth.

Time taken about 1.5 hour per gear.

Alan you can pay me if you like
