Subject: [CR]Re: wheels, tension, nipples, and the A word...

Personally, I don't have a problem with people using Spoke Prep per se...

...I have a problem with those who use it to hide inferior work. I see too much of that.

Also keep in mind that saying oil doesn't belong on spoke threads is like saying that a Phil Wood spoke machine should be operated dry.

Thousands of wheel builders before me for the past 100 years have used oil on their spoke threads...what suddenly in the past year has determined that to be FATAL?

When did butter become deadly - and margerine the no-fault replacement?

Kids for thousands of years were let loose to play, scrape a knee, earn a bruise or two...should I now tell everyone to keep their kids in cages like rats?

Seriously...pressing emergency right-this-instant paradigm shifting fundamentals please...or just admit to being anal about a personal choice.

I use the nipple click and response torque as part of the tensioning process. Spoke Prep tends to muffle it...

And once again, 2000+ wheels using bare threads and oil with no problems.

I'll up my wager. The challenger can bring a couple 300 lb brutes to test our wheels afterwards. The challenger is free to use Spoke Prep.

I don't need it - because I already know that a properly tensioned wheel doesn't require a "glue" to keep the nipples from coming loose.

To each their own...
