i agree with that. the temp range of a plug is how hot the insulator nose gets (not just the tip, the whole nose) but then again, when the tip of a plug is cooler, all that heat has to go somewhere...where? into the head.
not just the distance the heat has to travel. but the volume of material the heat has to travel through. only so much energy can travel through a conduit of a given dimension! this is why heatsinks use thick bases (when theyre any good). this is why high amperage cables are so thick. and why fuses are so thin.
a heatsink or head doesnt care about how long the fins are. what it does care about is surface area. (the stuff up im more than happy to admit with my first trial head
. though i said that was due to raw material supply constraints... which it was.)
they also like tapered fins, as the base is heavy, thick, allowing max heat transfer to the fin. the tips are cooling, dont have to conduct so much heat. also mechanical strength. flat parellel surfaces tend to resonate more easily. resonance is vibration and excessive vibration destroys aluminum. why do they make studios out of square? to stop resonances.
plus it makes for easy mould release during manufacturing.
the insulator doesnt stick out any further on a 4 than on a 11. the metal part, the thread, is the same as well. the internal nose length is different. the 13 has a much shorter nose, and also much thicker. theres more insulator material to assist the heat in getting out and into the head. high end exotic aero plugs use different ceramics to affect heat transfers as reducing the thickness of an insulator reduces its strength and therefore, reliability.
compare it to the fuse....use too low a rating, and the thing will melt! its trying to conduct too much heat for its dimensions!
and the analogy holds because it is on cross sectional area TIMES length. not just length of conductor alone..
youre both correct. why cant people just think a bit more? bridge the gaps between ideas?
lastly. at sea level, water boils at 212 f. you can fill a paper cup, place it on a gas burner, even use an oxy torch (dont overlocalise the heat) and until the water has boiled away and the paper is dry, it will not burn. it will sit at the same temperature as the water.
so, at sea level, you should get 212f with the thermocouple in the boiling water.
you, being at whatever altitude you say it is, 5000 or summink...lets see now... 202 f?
frozen into an icecube, as it melts, you should get 32f, altitude irrelevant as freezing temp of water is fairly constant despite reduced pressure.
either result showing a discrepancy means measurements are inaccurate.
i once had a lamborghini i used to thrash out in the paddock
why? it was made for it. but i loved that rustbucket of a tractor
ive seen planes fly using a victa 160cc lawnmower engine, with mods. anythings possible.
the wright brothers built their engine.
my point? cost is irrelevant. needs and necessity are. you could waste your life polishing feacal matter, or you could waste it polishing diamonds. they make the latter from the former these days anyway!
i work to the quality the JOB DEMANDS. so do all manufacturing plants.
you do not grind shafts to a tolerance of 0.01mm just because you can, if you want to make a profit.
you grind them to within 0.1mm because that is cost effective and all the job requires, nay, what is specified on the drawing!! and both finishes will work just as well in service. so why waste the extra time and money on the high finish when its pointless?
i do agree that china grinds to within 1mm when the job requires something nicer. so in this regard, sure...theres plenty of room for improvement. fix these and forget about gimmicks that do nothing
a friend found out last night why i still use a brick phone, after her smart phone screen cracked and become completely inoperable. bit of snipping at an old sim card to make an adaptor, and her old trusty bricks back in service too.
just because it cost a lot doesnt mean it was worth it! you dont always get what you paid for...
and for this reason i wouldnt buy a morini anyway because thats an outlay i really could not justify!
(though i spent much the same on a 5cc wankel...
)
