kids pedal car - electrical conversion !

I see you now are cheating with a bit of help from a budding engineer Yet another good vid.

I’ll let you into a secret. She does all of my machining; I just sort it out in the post production to make me look good !

In this episode we sort out a few issues on the rear axle . . . .!

Enjoyed watching this, it took me back to when I had to make a pulley I first made them on the router in mdf to make sure the pitch was correct.

A few picks here including the cock up :- https://photos.app.goo.gl/t5dJpvh7dBWzp9TFA

Thanks a lot for sharing these videos, routercnc. I really enjoy watching them. I'm also working on a CNC machine and now and, thanks to you, I'm also thinking about doing something like this after finishing it. I will try to finish it by next summer because we will buy apartment in Portugal with a garden soon and I want my son to have fun outside.

Hi Clive
Yes, one wrong number in the calculations and the pitch spacing was wrong. An MDF prototype would have been a good idea. By the way I can’t open the pictures on my phone as it needs an app or something.
I ‘invested’ time writing a spreadsheet that works out the key geometry for any HTD 5 gear size you want. Watch me never need it again !

Hi pratt77
Thanks. Sounds interesting. Remember you don’t need anything as ambitious as my machine to make small parts. Whatever you build just leave yourself plenty of time as these projects eat up the months !

Finally got some motion on the rear axle . . .

The rather splendid 'Gearotic' software from Art Fennerty will design many common styles of timing pulley for you, along with gears, gear trains, sprockets, ratchets, clock escapements and more wonders than you could ever imagine. All for one modest updates-for-life payment.
