kids pedal car - electrical conversion !

Having built my new CNC machine and thought I had better make something fun with it. I had been asking around for anyone with a Kettler type pedal car and I was offered one for free from a friend !

So I've drawn up the CAD, and we are off again on another video series. I need to get this one done quickly though, ideally before the summer, so my young daughter can get the most out of it.

There are some electrics involved later in the project so there may be questions . . . .

Episode 1: Getting started

Nice project, Have you thought about a remote Osh#~e button:beer:

Funnily enough I was talking to a friend about maybe doing that and he showed my the cheap blipper modules on eBay where you can remotely control a set of relays. These could cut power if required and have a 200 m ? range

I’m gearing this to go at a fast jog so hopefully I can keep up, plus there will be an ignition key and isolator on the kart.

For anyone interested here is episode 2 of the electric kart conversion, making the foot rest and throttle pedal . . . enjoy !

Episode 3 has been out a while for those interested . . .

And here is the new episode 4:

Very nice as always. If I may make a comment have you thought about the ware against the housing of the back of the spur idler gears.

I always enjoy the Vid's

Yes I thought about that quite a lot and discussed with colleagues. In the end I decided not to add anything further since they only turn very slowly ( just when cornering perhaps 1 revolution every second or so) and she might grow out of it before serious wear occurs. It will get a dab of grease on final assembly.

Hi routercnc, I am totally new to this site so still getting to grips with it. I tried to send you a message via another thread so I am not sure that will work so apologies if you are reading this for the second time. I was reading your story about how you bought your warco machine as I would like to buy one for the exact same reason you stated in your 2015 post. I just wondered how you feel about it after having it for 4 years and the company in general. I am thinking about the wm250. I am an abslute beginner but do not want to buy a chinese lathe. I would be grateful for your insights and feedback after all this time. Many thanks in advance.

Or start your own thread with a sensible title ;-)

Hi Steven

Apologies I have a lot on at the moment so only drop in here occasionally and don’t always log (therefore pms notifications don’t appear).

I’ll reply here for the benefit of others instead of a pm. I’m guessing you replied to my old lathe thread so when I’m near a pc I’ll copy this over.

I would buy this lathe again without hesitation and don’t regret it one bit. The VFD means easy speed control with loads of torque, it comes with a good 3 jaw & 4 jaw which I use a lot and a face plate which I’ve never used plus fixed and travelling steady rests. It’s quiet and I can make accurate parts on it. Has 3 speed settings for the lead-screw.

I added quick change tool post and DROs from day one and strongly recommend these also.

Be aware this lathe like many similar models are all made in China. Search out Weiss machines (?). But as I say no issues at all and Warco have been fantastic to deal with. I’ve bought lots of stuff from them and been very pleased with their products.

Other similar products are sold by Amadeal, Chester, ArcEuro if you want to have a look around but at the time the Warco was the better spec for the money (on the lathe)

Episode 5 is now ready. This time we broach out keyways in the drive gears for the differential, and machine out the HTD drive pulley. Enjoy !

My daughter thought it was hilarious and insisted I left it in 🤭

Thanks, that made me go back and watch till the very end. Oh the humanity of it!:hysterical::hysterical::hysterical:

For those following along - episode 6 . . . .

For those not following along . . . OK, as you were

You put me to shame :beer: nice work as always

Thank you. Not sure my daughter shares the same appreciation though - she just wants to get on it and whizz about !

Episode 7 is ready. This time, flanges . . . . plus bonus music (!)

https://youtu.be/iE6VYHP8_f8

I see you now are cheating with a bit of help from a budding engineer:yahoo: 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 . . .

As always, superb work, but you have an awful lot more patience (or engineering pleasure) than myself. Not tempted with shake proof washers on the bolts for the cover?

Thank you. Yes, I think it needs something but clearance is a bit tight to the main plate. I'll see what might fit in there, or probably just loctite it after the first proper run.

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.

Thanks Kit. Looks very interesting and comprehensive and as it is written or co-written by Art Fennerty (of Mach3 fame) I’m sure it will be a good product
At $120 I would need to make sure I was going to use it for something though.

Great videos! I left a question on your latest one. More a curiosity really.

I went slow on the tube cut because:
Part stuck out of the vice a long way
Tube thin and may resonate
That aluminium grade likes to chip weld

Thanks!

Strangely enough I actually found it while looking for software to design HTD5 pulleys a few years back. Then I discovered it was designed to provide all the tools you need to design a wooden clock and decided to try one as a good project for my new and very flakey wooden-framed CNC router and was hooked. I have since designed a couple of quartz/GPS-locked, all wooden gears, electrically driven pendulum clocks, one of which has a working prototype, and have plans for constructing some other designs once I finally get a bandsaw and a stock of suitable hardwoods later this month. Be warned, this software can lead to a serious addiction!

I can't remember if I linked to it before, but this link is to the GPS-locked prototype. https://vimeo.com/343781598

This episode is all the B's . . . .

You forgot the other B Blx. Still keeping an eye on this from Down Under. :beer:

Well spotted, that was a bonus one ! Happy hols

Electrics !

https://youtu.be/cm_qnhLfVpY

Beautiful as always, Very informative re the throttle electronics looking forward to the next one :beer:
Still Down Under.

Not the perfect throttle solution but it should work.

One more video should finish this thing. And doing the finishing work of course!

Final episode in this series . . .!

Have a great break, and see you in the new year (maybe with a very different project)
