My dream is to stick my finger in the flywheel spokes while it's running

There are a few diy / “open source” designs for a “Dynamometer” out there if i remember correctly. I think the most basic form is just a motor/generator, a multimeter, and some sort of electrical load? I do remember something about load cells too. At the end of the day even just lighting up some LEDs or a Radio as another comment suggested would be really neat!

Maybe he could try it on biodiesel or even vegetable oils? Just a thought

Here in denmark we only have a single type of diesel (B7) at regular pump stations. However it is possible to get GTL at some stations, but it's not common.

@@HomelabExtremeGTL with its high cetan number would be interesting.

​@@HomelabExtreme Ah, good to know. Thank you.

Is that true in all countries or what? Which country are you in where that is the case is probably a better eay to word my question. Either way caution and prevemtative maintain is good i guees. Also i am a MAJOE alternative fuels nerd, so in will take note on the potential Biodiesel issues! I know in the USA Biodiesel is rare (although all gasoline is E15 or so), B100 and various lower mixes are listed on the Energy.gov “alternative fuel center” but my area has none sadly.

@@ericlotze7724 I'm sure there is regional variation, but biodiesel is a common additive used to increase the 'lubricity' of the fuel, which is otherwise reduced by the chemical process which removes the sulfur from the fuel to turn it into ULSD. In Europe the EN590 standard for diesel fuels permits a biodiesel content of up to 7%.

I am a subscriber to your channel MrFactotum, and a great admirer. If you have only just discovered Mr Hansen, you are in for a real treat watching his previous videos (which I very strongly recommend) - an absolutely first-class craftsman, and I think a man after your own heart. He seems not have published any plans, but perhaps he will answer for himself. He has a couple of videos describing construction of some of his masterworks, but none actually showing all his processes. Essentially it's old lathes, a bit of milling, and very skilled hands, combined with a real engineers design ability. I have seen no other true model diesels, perhaps they exist (most things do, somewhere) but at this scale it is miraculous he has worked out a system for getting them to run, it seems to have taken him several decades, using old early 20th century engines for inspiration, and working forward from hot bulb engines to true diesels.

@@thisnicklldo eyup tnld, i know you sub to me, it registers with me all the subscribers who take interest by commenting to me. I try to make a point of remembering everyone👍👍 Thanks for taking time to message me, yes he's a great miniature ( some say model but model to me doesn't do any craftsman justice) engineer and machinist, i was particularly interested in his gear cutting on his lathe as i was thinking in advance to perhaps make my micro lathe do similar, in the future, once i get it finished, tested and used. There is some great people on you tube sharing their skills, some go above and beyond in sharing their knowledge. I get why he does'nt produce plans, it's his individuality of workmanship and it can get very time consuming when many want his attention and most don't intend to do anything with it. So each to their own. It's a shame though his unique work isn't drawn up and detailed, or may be it is!!!!!privately ATB👍👍👍👍Kev

Yes, and a couple thousand plastic parts :)

A great benefit of it is the smell, or rather the complete lack of it.

They stopped using clips in the eighties to ease the recycling. Then they began using them again. Now we have both, I rarely see a glued newspaper. Same with envelopes. They have been recyclable, then not, then they were and now they are not. Humanity is running in circles as usual.
