Hopeless Bike Mechanic Highlights Incompetence in his OWN videos: AN ENGINEERING REAMING

I don't ever claim to be a good mechanic, and I certainly wouldn't do it as a job but if I did do it, I would try and be a bit more knowledgeable than Reginald Scot.
This highlights a growing trend of amateur cycling KZbinrs dabbling in Engineering concepts - there is nothing wrong with that but it is unfortunate if you end up looking like a fool.

[@agie170hss2]

Two points to make on this video: 1 -- I'm surprised you didn't mention that he wasn't holding the calipers "square" to the bore of the BB shell? Even assuming he had the touch of a master, there is no way to obtain even a "relatively" accurate measurement on a bore with calipers unless the internal jaws are square with the bore. 2 - Not to nitpick (but I'll do it anyways), at 9:30 in the video you talk about setting "pre-load" on a Shimano crank (or others). Technically, I believe a better term would be: "adjusting end-play". The last thing anyone should be doing on crank bearings is pre-loading them axially. Even if end-play is adjusted to zero, it is technically still not pre-load. 👍🙂

I would agree, End play is the better reference.

The resolution of the calipers is 0.01 mm which is more than double to the machining tolerance of the bearings. No amount of experience can fix that. Calipers were never meant for precision measurement. Telescoping gage and micrometer would be so much better but he wouldn't know how.

[@tegheim]

To even measure hundreds with a caliper is... just because it says many numbers on the display, it doesn't mean that you are able to trust that it, A) measure correct, B) YOU holding it correct... As a 25year machinist, this makes me cry :) Use calipers to get the ballpark. Then use correct tools to confirm the measurements.

Even during COVID lockdowns, when people stayed home, CO2 emission only dropped by the single digit percentages. Blame the fossil fuel corporations for the pollution, not yourself!

[@user-uj4pe1qz4c]

There was a Park Tools video where the mechanic measured the inside of a seat tube with a pair of callipers and widened the seat tube top slot (where the seat bolt is located) with an angle grinder. I pointed out that on both occasions the correct tools were not being used, i was accused of being pedantic. An open discussion between Hambini and Reginal would be worth a watch and more productive.

[@audiolatroushearetic1822]

To be fair, a bottom bracket or a bearing shell has way stricter tolerances than a seat tube slot. No one would use a micrometer to measure it since all seat posts come in diameters with .1 mm increments at most and are somewhat standardized for many models/brands anyway. Also, as long it's steel and not carbon or high-end Al-alloy, I can see no detriment in using an angle grinder.

[@philoso377]

Hambini know best. For those who knows caliper well he can tell us that is a cheap caliper not fit to the measurement for three uncertainties. (1) +/- 0.1mm factory tolerance and (2) OD and ID jaws manufacturing offset to about +/- 0.05 to 0.1 mm. (3) Spring loaded skid pretension free play. What we have here is a press fit parts a BB shell. What else can we use? Experienced mechanics and engineers outside of a calibration lab often use two steps process. Use a good old mechanical caliper1 to contact “feel” the shell ID in step-1. Use a known good digital caliper2, set zero first then adjust it in multiple minute decrements until he gets the same frictional “feel” on ID previously reproduce that feel against the jaws in caliper2. Then record the display reading. Why not direct w/caliper2? Because we have rail to skid free play plus flex in the caliper which varies in proportion to the handling force during measurement.

Biggest issue I have with removing bearings, you NEVER re-use them so don't remove them until they are being changed. When that is happening, it doesn't matter if you use a puller or drift them out. As far as I'm aware, (plus over 50 years as a mechanic) you don't 'preload' deep row ball bearings but you do take the piss out of engineers who can't work on their own stuff because it's too difficult and only possible during assembly at the original factory (yet we manage to invent ways to fix the shit turned out without just buying new or sending it back)

If you're actually into cycling and ride alot it will cost you far more money taking it to the bikeshop multiple times a year than it is to just buy the tools yourself and watch some youtube tutorials, and you don't have to worry about someone else messing with your bike because they have other ideas of what needs to be done or how it should be done.

You shouldn't have brought up the subject of co2 given all the misinformation around the politicized subject of global warming/climate change. Just to inform you on how important co2 is to the environment and all life on earth, I submit the following facts, etc for your further reading: All life on the planet dies in a mass extinction event at co2 levels of 150 ppm , plants can no longer live below that level but levels below .03% would drastically reduce plant growth. At .08% co2 plant growth doubles, at .12% plant growth triples. However, not all plants use co2 the same way, type 3 plants groups(grasses, corn, etc) have only one pathway to use co2 and requires direct sunlight but type 4 plant groups have two pathways to utilize co2 (Deciduous trees) and do not require direct sunlight and convert 2x the amount of co2 to oxygen . Type 4 plant groups start being replaced by type 3 plants at co2 levels below .04%. .... With higher co2 levels comes stronger plants as well with reduced need for water, fertilizer, and pesticides. Runoff from big agra farming practices is polluting the planet and destroying our health (nutrient content and micro-nutrient content of fruits and vegetables is 75% lower than it was 100 years ago. The mass hysteria surrounding climate change/ global warming has ignored the issues that will kill off humanity 100 x faster than climate change ever could. Historically, of course, the planet's co2 levels have been over 8x higher than they are now and apparently the planet survived quite well.

[@SimonHarlow]

Kind of agree with the last comment by TobiMc. I think it is good that channels like Hambini's point out bad quality control and poor industry practices and I'm not sure why Reginald Scott seems so anxious to try to get one over on him. None of us is perfect but there are ways of pointing out a person's errors, or what we think might be their errors, without trying to rubbing their nose in it. It's especially dangerous if you turn out not to be right or not to be perfect yourself. Personally, I would rather see a good-natured exchange based on differing points of view. The thing about grease is a case-in-point: Reginald says its fine and Hambini says that it may not be. I tend to side with Hambini in that Grease is a mixture of things and I would want to be fairly sure that none of the components, presumably the more solvent-like organic chemicals, would damage the resin of a carbon frame. One would hope that any grease marketed to the bike industry would be fairly safe on carbon but, as channels like Hambini's have shown, the bike industry is not always that good at doing things properly. A few years ago I went into a book shop and asked if they had any books about lubricants; I was told to look in the non-friction section. I'm so terribly sorry....

No Idea, the video is 7 years old, the bike was bought in 2013 I think.

Jeez. You've been sitting on this to give it as a Christmas present 😅

I don't trust anyone who pronounces 'aluminium' the way he does.

[@GT-sc5sk]

And still your maintenance was rubbish

[@simonirvine1628]

As far as the top cap and bolt goes, remove and tap the cap and separate because you do not want to tighten up with the cap bonded with the bolt, you want the cap separated from that motion when tightening up the bolt. Its just full of crap/dirt/gunk from you not being bothered about the weather with the bike. X

The sarcasm. Love it!

@@Trippenzoid your comment sounds like a much needed self-reflection, tell me I'm wrong.

In automotive you use certain tools for certain jobs. I do my own bike work. Having a mechanical background.

One note: a cheap digital vernier caliper is about as consistent and accurate as a “insert crap & or junk analogy here”

[@markorajh1004]

I have luck... bike mechanic removed bearings on my old alu wheelset with that odd dentist tool... So I would rather bring my Hypers to my dentist when needed - anyway, she is a psychopath, she says, when I come around. Thanks, Hambini, you saved my teeth (I don't care for old wheels).

Merry Christmas Reginald

I must be here for the sarcasm because I didn't know self aligning bearings were a thing. TIL.

[@johncrow5552]

If damaging the spacer is bad, why do you have videos of you hitting one with a pin punch?

[@skriuttutt]

Hi Reginald! How many alt-accounts can one man have???

[@jackfrost838]

The measurement of the bottom bracket with calipers is not accurate cause the caliper "fingers " are square so the actual dia would be slightly larger. ( I think you have mentioned this before ) .

[@littleshopofrandom685]

They are actually sharp blades at least on good calipers, but its is near impossible to guarantee they are centred and perpendicular so calipers are at best good for a rough diam. To add to that, most cheap calipers under $250 or so do not have enough precision to measure a bearing bore though even if you did manage to pull a real number. 0.001" is about all you get form a basic mitutoyo with is not enough to accurately assess PF30 tolerance. If you have a $20 amazon type... 0.002" over 2 inches is dream land. It will tell you absolutely nothing.

[@timtaylor9590]

I use wax on parts I'm afraid will seize or corrode. Only grease or oil in sealed bearings. Seems like wax is more water proof and will last longer to which means better protection.

[@francismartinevans]

Hi Hambini. I have a question technical questions about measuring BB30 (or similar) bores in frames. Do you prefer to use a telescopic gauge and an outside micrometer? An inside micrometer? Or you prefer to use cylindrical blocks used as no/go gauges? Additionally... how do you check the two bearing surfaces are concentric, and/or parallel?

[@Hambini]

The gauge is the best way for an overall measurement, if the hole is oval, a stick mic is better

[@breakingbikes]

This is very entertaining... Regi started something he couldn't finish. Maybe he "under estimated" you as he has an "Aldi ruler" lol.

[@thecatsonholiday5932]

Wot is it with hambini ? He seems to attract more than a few stalkers 😂

[@MartinE63]

Well they want to know what aerospace / F1 factory is sited near Grimsby. Also where and who actually machines his bottom brackets.

Did he even zero his calipers.
