Where to Find Axles, Gears For Kinetic Sculpture?

sneakyimp writes "My brother is an architect and sculptor and wants to create kinetic sculptures powered by wind, steam, and sun. He wants to avoid electrical systems and keep this mechanical. He's prepared to cast metals for custom parts if necessary, but is hoping to find a cheap source of gears, axles, and bearings for the internal mechanical workings of these contraptions. We'll need things like miter/bevel/spur/helical gears, standard and thrust bearings, and axles." Read on below for more on the details of what sneakyimp is looking for — dismembered Capsela units won't do it. sneakyimpo continues: "These parts won't need to support much power or torque (probably less than 1 horsepower / 550 ft-lbs). Ideally, we could get a kit which contains a variety of bevel and spur gears, a few axles, and standardized connect interfaces — kind of like a box of Legos for tinkering and prototyping. I found the Stock Drive Products site and it looks like an extensive catalog, but one really needs to know what one is looking for and I don't think we're there yet. I've also found custom gear manufacturers and cheap plastic hobby kits but these are either too outrageously expensive or ridiculously under qualified for the job at hand.

I was wondering if any of you robot builders or mechanical engineers could recommend a good starter kit with an assortment of gears or perhaps a supplier that deals in appropriately spec'ed gears rather than industrial-strength SUV transmissions."

breakdowns etc.... it's way user friendly, & the rock solid kode base is freely available everywhere in the universe.

as everything made by man fails, we note; greed, fear & ego (in any order) are unprecedented evile's primary weapons. those, along with deception & coercion, helps most of us remain (unwittingly?) dependent on its' life0cidal hired goons' agenda. most of yOUR dwindling resources are being squandered on the 'wars', & continuation of the billionerrors stock markup FraUD/pyramid schemes. nobody ever mentions the real long term costs of those debacles in both life & any notion of prosperity for us, or our children, not to mention the abuse of the consciences of those of us who still have one. see you on the other side of it. the lights are coming up all over now. conspiracy theorists are being vindicated. some might choose a tin umbrella to go with their hats. the fairytail is winding down now. let your conscience be yOUR guide. you can be more helpful than you might have imagined. there are still some choices. if they do not suit you, consider the likely results of continuing to follow the corepirate nazi hypenosys story LIEn, whereas anything of relevance is replaced almost instantly with pr ?firm? scriptdead mindphuking propaganda or 'celebrity' trivia 'foam'. meanwhile; don't forget to get a little more oxygen on yOUR brain, & look up in the sky from time to time, starting early in the day. there's lots going on up there.

we note that yahoo deletes some of its' (relevant) stories sooner than others. maybe they're short of disk space, or something?

Re:Torque...

Not to mention the ambiguity in lb -- is that lb mass or lb force? N.m makes a lot more sense to me, then if you want to talk about energy you can use Joules. I don't understand why America still uses these crazy units.
