Hi, all.

A question to you experts.

I'm presently researching a project on the use of shot peening to clean/repair/strengthen threads.

In particular, I'm looking for articles that would disclose the use of shot peening (with any type of shot, i.e. ceramic, glass, metal, etc) to clean/repair/strengthen threads (especially drill pipe threads) PRIOR to June 29, 1994.

With everyone's familarity in this technology field, I was wondering if anyone is aware of any earlier reference to this.

I've already talked with Jack C. about this, so this is directed to everyone else.

Plus I have already reviewed the literature in this excellent library here, and the papers at www.shotpeeners.org, and several on-line literature databases (like i.e EI Compendex, Petroleum Abstracts, etc.) The patent databases have also been searched.

Thanks, Todd
