Talk:Peanut butter wrench

I am a professional mechanic in a bicycle shop, and in my experience, any common 15mm socket will remove the bolt (or nut, on very old spindles) used to secure the crank arm to the bottom bracket spindle. This bolt or nut was only used on older square-taper bottom bracket spindles, as most modern square-taper bottom bracket spindles use a flanged bolt driven with an 8mm allen wrench. The older bolt and the newer bolt are interchangable. Newer Isis, Octalink, and external-bearing bottom brackets do not use a 15mm-headed bolt or nut at all. The "peanut butter wrench" style of wrench is the only one-piece wrench that I know of that will accomplish the task. I have adjusted the phrasing of the article to better indicate this.

As an aside, many companies make a wrench similar to this, that also incorporates a box-end or open-end wrench, or other tool, on the handle, or dip the handle in plastic or foam, all of which make the wrench less suitable for use as a peanut-butter-spreading tool. 71.209.51.18 (talk) 05:46, 9 November 2008 (UTC)

Me again, here to correct my previous edit. I mistook the sizes of modern crank nuts and bolts (14mm) with older crank bolts, which were 15mm. A regular 15mm socket is too large to fit into the crank, so a thin-walled socket must be used, as was stated in a previous revision. I will add that back in to the article. My apologies for any confusion I may have caused. 71.209.51.18 (talk) 18:29, 30 January 2009 (UTC)
