I welded up a pallet ripper after seeing my buddy's store bought version. Let
me see if I can describe, 4' of 3/4" or 1" black iron pipe for handle, 8" of
same size for fulcrum, two 6-8" pieces of same size for prying arms.
Constrtuction, 8" piece welded to 4' piece to make "T" two pieces are ground at
there ends to the contour of the "T" and welded to the 8" piece to make
lifting/prying arms. Should look kinda like a pickle fork when done, except
lifter/pryer arms come off of fulcrum at about 45 degree angle.
Space pry arms so a doubled spine pallet will still fit between them. To use
slide lifters between pallet deck and pry apart. Also very useful for taking up
outside decking.
This took almost as long to describe as it took to build. As with most home
built tools it works good enough that I have not bothered to improve it. The
suggestion on pryarm spacing was learned after the fact.
