Hello, there!
Two years passed - and, nothing is built! I am shocked and ashamed.
But, Nils will have a 3rd birthday in the late December, so I hope that pedal-car would be finished for the Spring rides!
Ciao,
Zoran

Zoran,

Good luck and I'm looking forward to watching your progress. Keep it light-weight with not too much friction and it will go well.

Hello, there!
Cold rainy days finally arrived here! As I caught a cold in Belgrade and it is still with me - no work neither outside in our garden or my quadricycle nor here in a basement of our building (my small and cosy workshop) is sleepy as I am.
I used a ton of paper handkerchiefs... Good thing is that paper here in Bern could be recycled so not too much waste at general look.
(I do not buy anything made from recycled paper - I just gave them material!)
--- ---
So, I am seating now at my favourite table at the corner of our beloved PUB and think about what to do while doing nothing...
I decided to search a little through my 2-year old past and see what I was doing from the start of this topic and still didn't finished pedal-car for my Nils.
This is more a memo for me than useful for other, but that is the PUB anyway...
--- ---
There were three 5-6 week long holidays spent in my Belgrade – good!

There is continuous work in our small garden – not too hard and occupying, but...
Nothing to be compared to Denny or Woody and some other of members have compared to size, beauty and quantity of work...
Our garden parcel is a part of a bigger communal garden where we rent our part.
Good tradition in Swiss that every free space not still prepared for construction (buildings with apartments of offices) is temporarily given to people, sometimes even through dozens of years.
Such gardens are mostly at the periphery of towns, but sometimes quite near the centre of them.
Our is something between and was just by building where we had a flat before this one now.

We took it more for a pleasure than for serious work on agriculture, but something must be planted there.
More work was done on cleaning weeds all the time – it grows like mad and cutting grass (also mad)...
But, as a result, we had blackberries and strawberries, zucchettos, salads, corns, beans...
Then, some sunflowers and tobacco – more for decoration than for use.
After a couple of years, we had the first grapes and apricots.
All that in modest quantities, but not so bad quality. So, a lot of work and small benefits, compared to necessary of sweat, but at the end good fun for me (working) and family (eating fruits of my work).

For keeping of tools and protection from bad weather, but more So, for weekends and barbecue with family and friends, or alone for two of us - I built small garden-cabin (always wanted one from childhood trough entire life). There was a lot the of hard work from the transport of material to construction, working alone and without any kind of power tools – no electricity at garden... So, there is a nice place inside and even better under the roof of veranda – but the best is outside!

Unfortunately, last year I must reconstruct roof over veranda: too bad material and not-so-good solutions (mistakes made by myself)...

From the same reasons, this year I reconstructed roof over the cabin!
No photo of fully finished roof over the cabin...

Finally on the pleasant project: a pirate chest as a gift for my stepson's baptising!
Planed for presents with a special department for money! Pitty, it wasn't full at the end of the ceremony.
There are some differences between poor Serbia and rich Switzerland.
It was built in my modest workshop adapted in a basement of the building where we have our flat.

.. as I was in a mood for the wood-work, and there were some needs - I built a bigger wooden box that stayed now at the veranda and serves as storage for bigger tools and in the same as a reserve bench for guests!

..obviously, I am still not fit for work outside (cold and rainy) or in the basement workshop!

Zoran,

For the swinging pedals on my car, I planned to use a clutch to effect reversing the car, as swinging pedals cannot be reversed.

Instead, I now plan to use a coaster brake hub as a idler. Made for adult trikes, these hubs have a I put and output gear on them, so the pedal power goes into one gear, then is transferred to the drive by the hub shell mounted gear.

The secret is coaster brake hubs can roll backward without turning the pedals, unlike freewheels/hubs.

I had to do some tweaking on my model, but I’m about to lay up the body/frame and start to get mine rolling. I plan a live axle with both wheels driven. Why not? Turning at pedal speeds will be fine.

I think. smiling smiley

Peace,
Robert

==================================
Hello, Robert!
Thank you for always interesting inputs about HPV transmission issues...

Once, I designed (in my head and at the paper) too complicated system of using two free-wheels, one for each wheel, one turned for 180° so that I could have forward-revers propulsion for HPV quadricycle... However, later it seems to me that such a system isn't possible, but maybe I would try it once at the full-size model of the rear part of quadricycle...
--- ---
For this kid-car, I will try to make design simple and cheap as it could be, quickly built - so, not too many complications, but cute as much as possible.
Therefore, I abounded idea of making it as quadricycle using components of the adult bicycle with nice and wide white-wall tyres of 28"...
That bicycle with the broken frame, I would keep for some another project for myself...

So, I will make three-wheeler with a single wheel at the rear, better said with almost entire rear part of kid-bicycle with 20" wheels.
Bought 2 separate wheels 20", one shall be as reserve wheel, more for the style than necessity...
--- ---
For my full-size adult HPV quadricycle, I planed two derailleur systems, one for each side. But, for now, operating is just one, left-side.
Probably no use of propelling both wheels, but that could be possible... The only use of it is at full-straight rides...
--- ---
Live axle for CK-HPV quadricycle could be an interesting approach.
Maybe you would need more power at cornering if there is not differential, over asphalt, but good for off-road adventures...

As always, some sketches would be interesting and useful for all of us...

Ciao,
Zoran
