Miniature operational Model T model

Post by jiminbartow » Thu Aug 01, 2019 12:08 pm

I don’t know if his link will work, as I was unable to try it out in the preview section, but if it does work, you will see a fellow cranking his operational model of a Model T just as a full sized Model T is cranked. I wish mine cranked and ran this smoothly. LOL! Jim Patrick

Well, I was lost for words. Skill, time and patience....

She even sounds like a T when running!

That is totally amazing, I wish I had a fraction of the talent, and skill he has! Congratulations on a remarkable acomplishment.

Been kicking around on the net for some time but I take it with a grain of salt as a running model under it's own power. I just can't see microscopic carby jets being able to atomize gas to be a runner! maybe an electric motor in the box on the back? :D

I wonder what kind of body goes on it. I’d like to see it complete, with body and fenders. Jim Patrick

Kerry,

Small carbureted engines are fairly common in the modeling world. I’ve run 1 cylinder, 2 stroke, reed valved engines as small as 0.020 cubic inch displacement, and 0.25 cubic inch, rotary valved engines with barrel type throttle carburetors with separate high and low speed needle valves. So carbs work, even in a very small scale. By comparison, the engine in the video actually looks quite large... ;) I’ve seen 4 stroke engines with overhead valves and regular spark ignition smaller than 1 cubic inch.

Keep crankin’,
Eric

True Eric, but a 30 to 40 cc 4 stroke model plane engines usually has a carby some 30 to 40% of the engine size, way off scale to look proportional, just can't make them smaller to be functional. The 2 stroke ones are the same, large fuel supply and way off scale.

True also, however they are designed for high power output, and often high RPM that needs a lot of breathing. These small scale engines on the other hand are not powerful and only run short periods, so don't need the large throughput carb.

Cheers

Another true Adrian.
Youtube have some very interesting clips on small scale running engines but I can't find anything that seems to be running with a carb as small as a thumb nail which apears to be the size of that T carb. But of course we will never really know if it's a real runner unless someone can say they have actually seen it in person. ;)

When he moves the crank you can hear a few exhaust pulses. A four cylinder 4 cycle engine will only put out one exhaust pulse for a quarter turn of the crank. Albeit a beautiful piece of work, IMHO it's not an internal combustion engine making that sound.

Unsafe using his right hand to start it, he may be sorry when he gets chauffeur fingernail if it backfires.

some people would complain if they were hung with a new rope, in my collection i have a model t like the one pictured , it was at the show in Windsor VT, a few years ago, it was exact in every way, EVERY WAY! when the rev pedal was pushed with his finger it backed up, when started the timing lever had to be retarded , it idled it smoked it was a miniture model t, a foot long. if i were 3 inch tall i could have driven this out the door. how can any one have the stick to it to turn something like that out of flat stock.. but then again i collect pocket watch's and i have what is called a fuzee chin driven system ,the chain winds up on a cone disc, two of them just oposit from each other, one has the spring within, this watch was hand made in England in 1790's the chain looks like a string of hair, each link has 4 seperate parts, the pins and two links,to see this you need a magnifier glass. so i guess there are them that can do this work. its just hard to grasp that hands can work on thing that small and make them work too. in looking at the chain under a good glass i can see the work was done with a file, then there are the two holes that the pins fit in to. and no super glue. sorry MR Jeff.
