Made a pair of I-don’t-know-what-theyre-called things to mate with the rear latches of the model car I’m building.

Now they’re done I realise they’re not thick enough to hold the rear door flush with the rear wings. So I’ll have to make some sort of spacers…. Maybe a flexible filament 3d print to make rubber washer stops? I don’t know.

Here’s where i am overall:

Its taken a lot of work and mistakes to get here. The plans provided are very much geared towards buying the kit from them. So I’ve had to work out a few things myself which I’ve found difficult. The front steering I’m satisfed works - there is a bit more slop that I’d like but at least the way I’ve done it I can adjust the tracking if not the camber;

The stub axle things took a few goes to get right. more than a few. In the end to get a neat, square C section I used 100x50 box.

I’ve a good bit of the electrics solved, I think. Speed control, front lights, I did have a horn but it must have been pulling more current than the regulator I was using could cope with so I guess I’ll wire it direct to the battery instead. I still have rear lights to fit and cable.

The next problem is although I had a quick test run and it was fine (too fast) I need to work out a way of keeping tension on the drive chain... I have plenty of skate bearings so thought maybe use 4 of those on an m8 bolt on an arm with a spring….

I don’t know. Doing all this has shown me the limit of my abilities and every time look at it I seee all the things that aren’t right.

Fair play to you - I got the plans to build one for my grandson and that’s as far as it’s got.

 

[Eric the chicken]

That ground looks very dry.

At least you got as far as getting the plans.

I made something to make me smile when I drive as it's upsetting burning fuel. Smiles for miles people.

Yep, that annoyed me 20 odd years ago when I built my lads. Went my own way particularly with the drive train. Changed the wheels for these bigger ones too.

It never got painted. Control was direct on line with no speed control. Just a limit switch as an "accelerator" through a bfo relay. No brakes either.

I was miffed before I even started - the plans state you can only build one car and the plans can’t be sold on!
Sorry what? You sold a book, not a licence - and you don’t get to tell people what they can and can’t do with a book.
Imagine buying a cook book that said you were only allowed to make each recipe only once?. Absolute nonsense.
Then I realised the assembly photos were for the bought kit, not the parts in the plans and there‘s next to no info on the electrics and motor requirements (just buy it from us). Sorry, rant over.


The way you’ve done the drive train looks really good. Mine may shake itself to bits and I’ll have to do it that way too, time will tell.

Its hard to see from the photo but I’ve used a bike gear stack for the drive sprockets. Idea is I can adjust the top speed ( and torque) by choosing a bigger gear in the set. But it adds thedifficulty of sizing the chain.

I wish SWMBO's cook books said that.

Belt drive for the first stage, then chain drive. Never fixed the chain tension issue one side. Literally needed a tensioner. One posh bearing and 3 Chinesium equivalents. A few more pics. The black were the old, smaller diameter wheels:

Used two of these motors running on 24V. Got them from DISTEL / Display Electronics in South London when they used to sell lots of stuff for Robot Wars etc.

Always meant to get a 4QD controller(s) but never did.

Batteries were Yuasas cast off from wherever I was working at the time:

It'd happily convey 4 kids around the garden. My lad loved driving it at night with the lights on. Also made a circuit around the bungalow. They were 12V halogens. Now I'd of course do LED.

Used to have to load it into the back of the estate and he'd drive around the field in front of Brands Hatch. Did some miles.

Maybe I'll finish it if any of mine produce grandchildren.

Saying that I bought two spares / repairs mobility scooters to make another couple. You've literally everything you need. Lights, speed controls, brakes, indicators.

 

[Dev]

I found these for £65 each and bought 2. 24v 250W.With only one driving it was carrying me no bother on a flat. bogged down on a bit of an incline.
But that was using the second smallest bike gear. So both motors and the biggest gear should be good. I hope.

That's the future, it practically drives its self anyway.

I did some fag packet calcs somewhere for my gear ratios, I'll see if I can find them.....

The other day made an interceptor in my mates yard, couldn't be waiting the six weeks delivery time for a ready made unit.

What is it, like a septic tank, how does it work?

The idea being oil/fuel floats on water, that one would have a capacity of about 800ltrs before anything went down the drain, concrete lid and manhole goes on top of the big concrete ring.

It's lucky then that nobody laid the paper plans out, measured them accurately and put them on CAD.....

 

[plantlife]

I looked at buying the plans for that kit. I didn't get them but instead I bought an old mobility scooter and old land rover indicators, mdf and a few other things. I even measured up a coin ride on postman pat van (that was the plan for the design) but since its already been three years it's changed to a Land Rover.

My fault. I keep telling myself I need a new shed and I'll build it with him in that, :/

 

[KemppiFrog]

Those belt drives remind me of the old Daf variomatic transmission. No diff needed and very good in snow.

Do so NOW.

They're only young once. My lad reckons I did do lots with him when he was little but I think I could have done so much more and passed on lots of practical skills if I'd have had a decent, warm, all weather workshop. He might I reckon even have gone into engineering rather than computer science.

People say they spend more time with their grandkids and I can see how..... now.

Hindsight eh?
