Andrew: I don't do any field work anymore so it's handy for me but I only use a heat gun for "burning" shanks. That's one of the ironies of our nomenclature, in "burning" shanks you're actually not supposed to burn them! dp David M.

We recently covered burning hammer shanks in class, and after noticing how much carbon has to be cleaned off the shank due to the open flame, it occurred to me to try a tool I had at home. It's the Weller Pyropen Jr. (WSTA6), which is a small portable butane-powered soldering iron that also comes with a hot air tip. It's the latter mode that I decided to try for hammer burning, since the hot air won't cause carbon deposits the way an open flame would. I figured that if it was hot enough to melt solder it might work for hammers (according to the spec sheet, it generates hot air at around 800 degrees F). Paul Revenko-Jones and I tried it out tonight, and sure enough, it worked quite well! Paul mentioned that he uses a heat gun for such things, but that it's more cumbersome to deal with, and the Pyropen is cordless and small enough to easily throw into a tool bag. I got mine at a local Fry's for about $50 (note, you need to buy a can of butane as well, it doesn't come with fuel) so it's not as cheap as an aim-n-flame but not super expensive either. Besides, I seem to remember some previous talk on the list about piano tuners rolling in doe, bucks, etc. :-) It also works well for its primary purpose as a soldering iron (and heats up in less than a minute). The only complaint I have about mine is that it's occasionally a bit reluctant to ignite, but I don't know if all of them are like that or just mine. Anyway, I thought I'd mention it in case anyone else might be interested, since it seems like a nifty use of the tool, and Paul seemed pretty excited about it. :-) Here are some links. Fry's seems to have the best price (like I said, I bought mine at a local store.. instant gratification!): http://www.cooperhandtools.com/onlinecatalog/literature/55702.pdf http://shop3.frys.com/product/2461450#detailed BTW, I have no affiliation with Weller, Fry's, etc; just happy to find that non-piano tools I already own come in handy for piano tech work. Take care... -Andrew
