Re: ACME or Ball?

Jan,List,

BS&A used to call those the "active cam" type. Basically the active
cam is their "work around" of the Kerk patent... (and it's okay, but
not nearly as good as the kerk, IMO.)

The other thing to be careful of with these nuts is the very low load
rating in most sizes; far less than what one would expect...

Finally, there's no reason why a home hobbyist could not duplicate
the kerk technique for antibacklash... (Just can't sell it)

Hope this helps,

Ballendo

P.S. Dave M pointed out to me offline a post I'd written awhile back
on acme screws. On reread it may be useful to those contemplating
using inexpensive thread types... See msg 20,284
