I'm trying to get started with some wheelbuilding. I've got a Park Tool TS-2.2 truing stand. Can I just rely on the calipers to provide a guide for centering the rim and dishing rear wheels or will I need separate dishing tool?

Park Tool TS-2.2 Truing Stand

A properly aligned TS-2 truing stand will show dish, as well as alignment. You rarely need additional adjustment after using it. However, if the stand is out of alignment, you may need to re-dish the wheel.

The easiest and most accurate check for TS-2 alignment is a properly dished wheel.

The best way to ensure that the wheel is properly dished, and thus an accurate alignment check, is with a dishing tool.

Bottom line, if you can afford the TS-2, a dishing tool shouldn't be a major expense, and is worth the cost, even if you only use it as a final, double check of the truing stand.

Great answer, and alignment advice. –  Glenn Jan 29 '13 at 15:05
    
Thanks. Just common sense. –  zenbike Jan 29 '13 at 15:07

As long as you verify the centering you don't need to do separate dishing.

You will need the centering gauge: http://www.parktool.com/product/centering-gauge-1554-1

Do read the instructions and get comfortable making the centering adjustment. It's not difficult. Biggest thing to pay attention to is to SLOWLY lower the gauge into place.

Happy Riding! (and Wheel Building!)

From the link you provided: The 1554-1 will help align the TS-2 stand, but for accurate work with the TS-2, working with a dishing tool such as the WAG-4 or WAG-5 is recommended. –  Glenn Jan 28 '13 at 19:39
    
YMMV, but I've checked the results of several wheels I've built on a TS-2 and never needed to correct dishing. –  Ken Hiatt Jan 28 '13 at 22:53

I too have built wheels using the TS-2 and like you haven't needed to adjust dish when checked against my dishing tool. Bottom line is a dishing tool costs more or less the same as an alignment tool with a higher degree of accuracy per the manufacturers specs. –  Glenn Jan 28 '13 at 23:14

It wouldn't hurt to buy an inexpensive dishing gauge for double-checking your builds. I have an old Performance one that would likely cost about $15 today, and it's perfectly adequate for this duty.

However, you can get the same double-check by simply flipping the wheel around in the truing stand.

Maybe I'm missing something but I think if you have a misaligned stand then flipping the wheel will only show your stand is out of alignment, not that your wheel is dished correctly/incorrectly. –  Glenn Jan 29 '13 at 3:29

Flipping the wheel (for the vast majority of wheels which are symmetrical, even though "dished") will show that both that the stand is properly aligned and the wheel properly "dished". –  Daniel R Hicks Jan 29 '13 at 4:34
