TIG weld
Hello Nathaniel:   Sure thing about signing off the license, however I'm not so sure how exactly it is supposed to be indicated.  I added written releases upon other image work....   yet noticed that it still came up short in the opinion of others.

Will this work?:  "This image is offered under [Cc-by-sa-2.5] by the creator of both the photograph, and its subject material.  TTLightningRod".   Should it say something else, or more?  You'll let me know.

As to my activities around here....    ya, I've been away a while for two good reasons;  One, I got too wrapped up in that frustrating wikipathology.  Second, I'm in the middle of a highly involved shop renewal here.  Lots to be done before winter, and of the utmost importance to me.  We'll have much to discuss, about vocational articles and craftsmanship, once the new equipment is up and running (Dec.).  You'll have to make an effort to visit down here, it's only a two hour drive from Penn U.   Take care,
