Why are quill stems and underappreciated diy item? They can be used to build all sorts of things yet nobody ever talks about this

can i make one myself? why shouldn't i just weld my metal tubes together at a 90 degree angle?

People who need a versatile construction set use 8020 t-slots or unistrut, not handlebar bicycle components.

Dexion is classic and integrates nicely with unistrut.

Because they rely on friction not postive retention. What have YOU built using them? There's your answer.

Everything worth doing has mostly been done, but the ignorant avoid knowing why extremely common proven solutions are such then see something they don't fully understand and get excited.

Mentioning that everything worth doing has mostly been done so that can be used as a basic option set triggers noobtards who instead should learn basic principles. When it comes to metal construction positive retention of parts is generally desirable.

Quill stems are a very specific exception where friction confers adjustability under light loads and where misalignment during a crash is an advantage because the friction adjustment limits loads thus saving parts. Those are OTOH not good qualities in most non-bicycle construction.

i was thinking at least the hex head bolts could be useful or the flatbar
feel like anytime you have to repurpose salvaged parts from somewhere it has to sit around for a long time that's why salvagers always have a big pile of stuff and the thing has to be designed around the salvaged thing

>> No.2793818

Yes, put a free sign on it and be done. Wise salvagers exist but we don't crave to save useless scrap.

I was thinking of using them for some shelving very recently. The idea was to build a scaffold of pipes held together with quill stems to hold up shelving boards. My city has some non-profit bike shops that sell used parts really really cheap.

Here's the problem: It's super hard to find two identical used quill stems. The distance from the handlebar clamp to the stem is all over the place and so is the diameter of handlebar they take. That's not an issue if you buy new ones, but there are cheaper ways to hold pipes together than brand new bike parts.

U bolts combined with angle brackets, or using threaded pipes that screw into fittings.

Used scaffolding for one. Used Baker style scaffolds make nice mobile shelving. Scaffolds and their hardware are quite versatile.

NTA but medical furniture like shower/ transfer seats, elevated commode chairs and stuff like walkers and crutches are usually available for cheap at thrift stores and yard sales, and have all kinds of tubing bends and telescoping click lock adjustable parts and brackets and such to be cannibalized, that are mostly in standard sizes and usually made of hard anodized structural aluminum.

every bolt connection is supposed to rely on friction in at least two axis and at worst bolt tension in the third axis
this is one of the reasons for torque specs
if the bolt is getting sheared or bent or if the bolted material is getting cut by the bolt then it was engineered or assembled wrong
