You can also do the opposite but then you would have to apply a shitload of torque. So for ultra high gear ratios you really only want speed to power.
This is how the different gears on a car are accomplished. You start off with a high to low (power) gear ratio so you can overcome inertia and get moving with higher torque. Then you progressively shift the ratio till your highest gear is a low to high speed ratio. If you try to start off in 5th gear, your car will stall. Neutral is 1:1 so the gear train just translates work from input to output.
Pretty sure you can machine anything lil bromo. I'm more thinking of machining my own "building toy" pieces. A set of standard parts that I can fasten together to make different stuff. Similar to but better than the technix Lego or knex.
whats the size and power involved ?
unless it involves more than 1/10 of a horsepower id say plastic gears will be fine. your just trying to shove a cat.
also toycars are best made of cast irons. you only need machining if its forged and you wont have a skill to machine one anyway. -
2019-10-25 at 11:29 PM UTCI used to work on an assembly line with an actual converyer belt. they would rotate us every few days so we wouldn't go into the bathrooms and blow our fucking brains out from bordom.
It was actually pretty cool.. because we would try to beat the quota .. but you had to do the numbers with a clean QC report by the end of the day.
Hydraulic Compressors have two buttons for a reason though. You want to have the same amount of digits on your hands by the end of the day as you started with. -

they rust though. lots of oiling ?
plastic is kind of an oily texture because well.. it's made by oils. -
2019-10-25 at 11:31 PM UTCAlso there are glass and some new plastics coming out with titanium and iron infused at a molecular level now. it's almost as hard as cast iron or steel.
this could be a huge game changer in toy making. -

I just snapped an axle. And again, I intend more to make some high quality "building toys" similar to Lego in flexibility but made from metal. -

it snapped because your abusing it by sticking into it the kind of power it wasnt designed to deal with.
inputting big power into tiny little machine is no more different than child rape. -

Originally posted by Big League jedi I don't really want to actually do machining as a job, I just wanna learn it and have the ability to machine stuff for myself.
it's called a TRADE for a reason, like electricians, like carpenters, a mason (not freemason)...a trade skill is more valuable than the education itself. if power ran down, i could still machine and fix things to keep tractors, vehicles, medical equipment, general machining off a generator. but it's not just the ability to plug your mill into a generator, but it's a skill to be set up while everyone else is struggling and you get the work....that is more of a doomsday approach, but it speaks volumes to have the skills of this trade when all hell breaks loose. you are still in position to survive because your skills benefit military, production, life saving equipment, and 99%of the population have no idea what your skill is, involves, let alone the fact you need to actually comprehend mathematics.
im sitting good in my skill and will/should always have job security and new job opportunities until i die/retire.
not everyone can honestly and truthfully make that claim about the security of their job skills and life.The following users say it would be alright if the author of this post didn't die in a fire! -
2019-10-27 at 4:24 PM UTCobviously everything in the machine shop is 3 phaseThe following users say it would be alright if the author of this post didn't die in a fire!

2019-10-27 at 4:26 PM UTCand generally, if you are a trades skilled toolmaker, you know already a great deal about electricity, and if you can work on metal from a blueprint, you can be a carpenter any day or a brick mason because they all are mathematically connected and have similar processes.The following users say it would be alright if the author of this post didn't die in a fire!

2019-10-27 at 4:29 PM UTCi tapped directly into a line pole (electric wires running on poles along sides of the road). i made a 200 amp breaker and from there ran 2 lines 100 amps. and then from there to my shop, pole bar, barn, home, and some animal buildings i installed lighting.
ran conduit and then fed my wiring harness and then connected ceiling shop lights and breakers for 3 phase :)The following users say it would be alright if the author of this post didn't die in a fire! -
2019-10-27 at 4:32 PM UTCi used aluminum wiring (more expensive) but put into 20 foot sticks of pvc conduit 3 foot under the surface which is 3 foot above water lines :)
that should last 30+ years.The following users say it would be alright if the author of this post didn't die in a fire! -
2019-10-27 at 9:44 PM UTCDo you believe the best path to learning is a technical school or should I just try to work at a machine shop for a few months or something?

the best way to is to have a job in a machine shop environment while taking classes. today's tech schools normally have machine equipment so if you are not on a machine at work, you will have one to learn from in tech class. plus, you will have a first hand look at how the instructor operates and explains what he or she or it is doing.
but that is the best way to cover completely and learn the fastest.The following users say it would be alright if the author of this post didn't die in a fire! -

sounds like your the kind of beta that bends over and sweating and doing all the hard work while being supervised by real men with guns in theoritical SHTF situations.
