I laced up my 5th (4th successful) last night. first time I didn't have to refer to the web or other wheels to make sure I got the pattern right. I don't have a truing stand so I waited until I got into work this morning and set it up in a spare fork with a dial indicator. I was a bit impressed with myself by how close I was initially. About 15-20 minutes later I had it within +/-.005 in trueness and hop! More than satisfactory for me but I am curious what is an acceptable tolerance for the pros out there?
Yay me,

Congrats! But I can't answer your question as I am going to be building my first wheel in the next month or so, after re-reading the Brandt book.

Woohoo! My tolerance is a lot wider than that. I don't have a dial indicator. My goal is that the rim be truer than the tire.

Five thousandths of an inch!
I'm not sure if an electron scanning microscope can see that! :thumb:
Rim brakes +/- 1mm Hub brakes +/- 2mm I don't actually bother to measure, but if someone asked....
I've got dial indicators, but I save them for other tasks like machine setup and alignment (machining)
I'm with noglider, the tire often has variances larger than the rim.

You might be surprised. I had about .02" of hop in a couple spots and +/- .015 trueness when I started and it was visually obvious when spinning, especially the hop. But I could tell right away I was a lot closer than my first few builds.
BTW this wheel is a Campagnolo Victory Strada hoop laced to a C-Record front hub using DT butted spokes intended for my Guerciotti. Next up is the rear on a Record 8-speed hub. I chased my tail a bit on the last rear wheel I did but this one has given me a bit of a confidence boost:)

Even tension is much more important than the deviation of the round/true when you are building a wheel.

"feels" good. But I know the co-op in Tacoma has a tension gauge. I plan on going out there next weekend to check my work.

That's a good book Whatwolf. But also, check out this tutorial. Best one I've read. It really helped me when I did my first wheels.

If it feels good, probably it is good. I've built a lot of wheels now without the benefit of a tension gauge, and so-far, it's all good.:)

Congrats, Andy - you know, I think I'm going to attempt to do a wheelset while in DG. Lord knows I'll need to keep my mind occupied after I get bored of riding the same 18.5 mile road day in and day out ;)
I have Brandt's book, too, and I think it will be going into my pack-out.

Once you've ridden on perfect-- and 5 thou is as close to perfect as we're ever gonna get in this vale of tears-- nothing else will do. Congratulations on spoiling yourself!
My problem's always been finding the start point, I finally figured out it is 4 spoke holes to the left of the hub logo for a drive-side 'push' spoke. Once I get that located, then it's all just counting by 4s.
