wheel truing
Hello. I live in a small remote Alaskan town and have started to do repair work on bicycles as there is no shop here. We only have about 15 miles of paved road and many miles of bumpy dirt roads. Most people use their bikes as transportation and recreation, mountain biking isn't a thing as we live on a former glacial moraine and it is pretty flat. I purchased a Park Tool TS 2.2 and was wondering if I really needed to get the centering tool. Mostly I just want to fix out of true wheels so people can continue to ride their bikes. I am self taught and have crossed the country on my bike but have little experience with this tool. I always wanted one and could use some advice from anyone willing to give it. I am ordering a wheel alignment gauge and think perhaps I do not need both. Thank you in advance.

You can check the dish by simply flipping the wheel in the stand.
I'd purchased a used 2.2 that was out of center.
I struggled with attempting to center it myself, but could only get it to center on one OL width at a time. Switch from say a 100 to 135mm and it was off.
I downloaded the centering instructions from PARK and followed them.
It's DEAD ON! First attempt. I might have got a little lucky?

You ALWAYS have to check if the rim is centered when you true a wheel...but you can do it by flipping the wheel in the stand or the frame as Bill posted.

I have found that getting the dish centered correct that most truing stands are not as accurate as a dish tool. The dish tool is just easier and faster. Clamping in the wheel and making sure the truing stand has things centered is not to my liking. You can easily make a dish tool for almost nothing. All you need is a straight board long enough to cover the rims and then cut out center and add a screw in the middle. If you do a lot of wheels the Park is probably worth the money.

Why do people insist on using the term 'dish'?

I don’t know. Because it’s a term that has been used for decades? It was an old term before I started building wheels and that was 40 years ago. What else would you call it?

I call it dish and will continue to do so even if some kid doesn't like it.

"Centering". People also mistakenly use "dish" to describe the section of a rim.

I bought the tool because I like to build my own wheels, I used other hack methods for doing it before I got the tool. The tool was worth the 30 bucks or whatever it cost. I don't generally use it when I true a wheel, unless it's really bad.

I have heard it used both as a noun and as a verb. I looked at photos from my wheelbuilding class and the instructor wrote on the whiteboard: "Dish to < 0.2mm gap".
Calvin Jones and Ric Hjertberg use the term dish, as does Saint Sheldon (he uses the term "dish stick" for the tool). Jobst Brant uses the term dish, but calls the tool a "Centering Bridge".
I am curious what pro mechanics do call it - I guess I don't know any pros, only people who work in bike shops or those who build wheels for a living.

“Centering” can apply to a wide variety of issues on a bike. Brakes are centered. Wheel in the dropouts have to be centered. The rider is centered both right and left as well as back and front. “Centering” could lead to confusion. The only thing I’ve ever heard referred to as “dish” is with regards to wheels. Saying “centering of the rim” is rather uneconomical in terms of word usage. I suspect that 90% of the cycling public would look at you with a blank stare if you called dishing a wheel by that string of words. Granted the vast majority of people have no idea what “dishing” is anyway.
You lost me. I’ve not a clue of what you are trying to say.

You know..."deep dish aero rims". I'm sure you've heard it used before.

I have spent the last 20 years as an editor, and if there is one thing that I have learned is that there is no such thing as the 'proper' term, and trying to enforce any term list on even a single company is like herding cats. Even when you think you have your glossary firmly nailed down, someone develops something that screws it up.
Dish is fine by me - and the trick is often not in getting the term 'right' but the description adequate that the people reading it understand what you mean even if they use other terms.

"Deep dish" has been an auto wheel term used to describe custom extra wide wheels with an uneven offset, you know, dishing. This was long before deep aero rims arrived in the bicycle world.

No need to buy a dishing tool..they are a no-brainer to make. If you can fix bikes/true a wheel, you can make a dishing tool.
As for dish vs centering..potatoes, patahtoes. There was a movement for a while "speak simply and clearly".
If a word is well understood and in common use, there's not a reason in the world to substitute another word that immediately raises the question..what do you mean? English is convoluted enough without adding to the pile.
If you want to rail against a word..try "clipless" pedals. Completely bogus term. There's nothing "clipless" about, for example, an SPD pedal. You step on it and immediately clip in. You even hear a click. The old toe clips were less "clipless" than the current clipless pedals.

That link doesn't show up until the middle of page 2 when you use "centering".

Especially when the term they want to use doesn’t really describe what is going on. With a rim brake, the front wheel’s rim is “centered” on both the axle and the hub flanges. On a rear wheel (or front disc hub), the rim is centered on the axle but not on the hub flanges. Calling that offset “dish” is just an accepted way of describing it. Sometimes you just have to go with the flow. Something may be technically correct but not all that useful in real life. I really doubt that anyone at IUPAC ask for the (2R,3R,4S,5S,6R)-2-[(2S,3S,4S,5R)-3,4-dihydroxy-2,5-bis(hydroxymethyl)oxolan-2-yl]oxy-6-(hydroxymethyl)oxane-3,4,5-triol for their aqueous extraction of Coffea arabica heat treated embryonic material.
Fun story: a couple of organic chemistry professors, co-authors of a standard graduate text, spent most of an afternoon sipping a bottle of wine while deciding what the proper systematic name of a couple couple natural products should be. The result was in the title of a refereed, published paper.

If you used the IUPAC name for sugar, people would take a week to get back to you on it.

Here it's used in a book from 1891 Taking the Dish out of Wagon Wheels (lostcrafts.com) Then this shop that makes wooden car wheels describes the advantages of a dished wheel. Dishing of Wheels (calimerswheelshop.com) .
