Keep us informed of your progress Mate. That "Car" would be perfect in Outback Australia with a few solar panels on it.

Has she been put into service yet? You could probably use your flash steam boiler if you could mount it to the engine instead of the welding bottle, then you would have a steam engine!!!

It is always a label issue with quality specialists!

Yes! Another WOWWS video - you've made my day :)

What is the first thing you picked at 0:12? Figs?

Glad your bether and congratulations on getting the cert for the Mott

Onwards and upwards Tim. Great news about the certification 👍🏻

cool to see you better

glad to see that you’re doing better

Just make a axial flux generator for the windmill then use the power to run a domestic induction hob

I agree that the small stuff making and your larger stuff are worlds apart. I do also think, though, that getting those voids out more would help this project. I also worry about your mold pressing, simply because the voids can't escape well enough. Perhaps you could aim beyond the sandwich press and clothes iron phase. How about a heated roller set? The warmed plastic gets rolled through warm rollers to press the voids out, like a giant pasta maker. Yes, you would end up with thinner slabs; but re-fixing them seems easy enough if the plastic is warm before the re-layering. I wouldn't heat them as hot as you got them in the molds, though. Malleable, not liquid. Just a thought.

What fun!

You should make a gas locomotive for your reilway

Nice sandwich made in a very entertaining way

Very interesting - A great experiment - Can't wait to see your next test with it

Very clever. (Nicola,from Italy)

Gorgeous!

unhappy keyboard near your cnc machine. and this magnet was a great project.

I wonder if you could use plastic film from packaging too, there's an unfortunate amount of it around. Great progress Tim!

Nice work

Check out how they make hockey pucks

Is this block lighter than the wooden one?

don't use plastic, it's not degradeable and over time there'll be a spread of microplastics which harms all living things, especially higher up the food chain as it gets more cocentrated. Plastic is not the future

You could spin the magnets faster by a gear ratio system or something that’s attached to the belt

More railway videos please thank you

To make glass clear they add a chemical that latches onto the microscopic slag that makes the glass cloudy. If you added something that would absorb oxygen and nitrogen under pressure that would shrink the air pockets. Unfortunately I don't know enough about chemistry to give you an example. Chances are good it would be something like clay powder, ash, sawdust, or even something like cement powder. Hmm, soap? Ajax? Some kind of dry soap, like laundry detergent? Or maybe that would add MORE air bubbles.

You think you could pull off dove-tailed slots for the bottom plate to slide into?

This is awesome! I'm just speculating but maybe if you filled the mold gradually it may help with air pockets? In other words, putting a little at a time, waiting for it to melt then adding more a d more it it fills.

I don’t think you need to taper the mold (to get a tighter tolerance on the ramming cap) Once cooled, you could use the ram and jack to push out the block…I believe

What I get from this vid: if Doctor Who had a DIY maker space during the dull times between saving civilizations, protecting culture, harmonizing the universe

Maybe you've answered this but, where do you get your waste plastic from?

First video of yours I have seen, good stuff! You did throw me for a loop when you used your 'foot' to help open that first mold though. lol

Depending on the forces and shaft speeds involved, you msy be able to do away with the bearings and simply drill and ream a hole in place instead. Some plastics are excellent bushing materials. Another trick ive heard about is to use a G clamp with the mold in the oven. You can increase the clamping bit by bit while the plastic is still molten. Depends a bit on your oven space available too :)

I think you are going to have to apply pressure at the same time that you vacuum out the air so that the bubbles of air are able to squeeze around the edges and release from the plastic itself. I know how it is though sometimes it's one step forward and two steps back till you figure out how to make it work. I have been using an LFP battery as a built in automatic jumper pack for my vehicle... Sadly it seems like the lead acid batteries that are being produced now just do not want to hold a charge very well. I was able to figure most everything out but needed to remove the ESP32 controller I was using as it would work sometimes and other times it wouldn't and since I am not a programmer using a logic circuit was just easier. Pulled the lead acid battery out a couple days ago and now the setup is one hundred percent running on the LFP with only a minor issue of a slight flicker of the dash lights while at idle in drive with your foot on the break (automatic transmission). Adding a small capacitor pack should solve that so have that on order now. The LFP battery is able to put out a peak of about 1440 amps instant, 720 amps continuous drain at 14 volts. The only modification to the vehicle was removing the lead acid battery, running a long 1/0 (8.25mm diameter) copper cable from the engine bay to the back then running a similar ground from the new battery to the body, and tapping into a switched power source and constant power while the engine is running. Everything else is located on the battery pack. It's nice seeing the animals come through the shop, you can tell they are loved. I had to put my buddy down a week after my birthday a couple months ago, the cancer was getting really bad and there was nothing else I could do.

Best video proof that water boils at PRECISELY 100°C that I've ever seen.

You could just lift the machine shed on taller stirrups...

We studied this sort of thing at uni, couple of observations to help you understand what's going on: 1 - it's not off gassing. Plastics tend to break down and release gasses or vapours at higher temps. All injection moulding and pultrusion is done at the LOWEST temps possible 2 - as plastic cools it shrinks. You always get a void "somewhere" in a moulded plastic part. Keep the pressure on as long as possible (like you did in your second video...) Cheers mate!

A copper tube ring covering all the magnets feeding water through it would be the best energy transfer as all the magnets would be working on the metal (and water).

Do the compass next time for orientation direction

I wonder if vibration would help? (As it does with form pour concrete for example.)

Love your resilience, Tim! You're as much about the jouney as you are about the destination.

Great video! I know I’m a year late to put my 2¢ in. lol but can you make the level apart of the wood cutter machine? Maybe move the wood cutter over, and make the level horizontal. Put the drive rod between the formula and the driven rod. From a new fan, been watching all your videos, still have some to go yet. You been doing this 10 years it looks like.

Looks like fun! I had great fun with simple go-carts as a kid.

Water hammer effect, water surging to fill void, generates a massive impolosion that generates a powerful shockwas of pressure.

what happened to the railway?😊

The magnets also heat up, but this is harmful for them. A more optimal design is a high-voltage generator with low current and a standard boiler through a step-down transformer

Great job! Understandably it saves on cost vs. welding and would stand the weather more than wood, but I'd be curios what is the time cost per block? I'd also be curios about the weight of each block. Would it be possible to mould it with some purpose made holes maybe to save some time on the bearing but also to remove weight without reducing the structural stability (say putting a few bars in the mould maybe and swiss cheesing it)

George Calin said the universe wanted plastic didn't know how to make it so made us to make plastic for it-- ?

Very impressed by the stronglier mould. Great work!
