Someone on some forum clued me in on removing nails from pole barn (Morton building) sheetmetal without damaging the sheetmetal by using a slide hammer and fork attachment. I cannot find such an attachment commercially for sale. I was hoping to, in order to save me the trouble of making one and going through any "design revisions". Anyone able to help here with a commercially available attachment for my slide hammer or with a pic of one they made that works? Just trying to save myself some time and work.
