I can't locate any decent priced fullers, so I plan to use some extra large ball pein hammers and make the pein into the fuller part, or punch ( I have the handled cutoffs already)...also, may fabricate my own from scratch using hot rolled steel rounds & plate and a rod handle. . . . Hardy Cutoffs. . .I also have two OCS 3"x3"x3/8" (one has knife edge in center, other on the edge) that after tempering, I will arc weld onto 1/2 sq 4"x4" 'Hardy plates. I plan to bring the cutting edges to straw, (after heating the entire OCS square to non-magnetic and quenching). Then by putting a slightly yellow heat 2"x2"x8" sq bar on the side (away from the cutting edge) until the heat moves up to make the cutting edge straw, then quenching in oil...seen this on that Colonial Woodworker show making a carpenters lathe gouge. . . . Thus far my only plan is to heat the hammer head to non-magnetic, and then immerse into ice cold oil. I know this can't be that easy, thus my plea for help. In advance . . .thanks chas.
ps. Found some great B/S (not-Bull) video on my Samsung Galaxy 10.1 tablet (Android OS) but I don't know how to locate the file where the URL resides (when I save them), so thus far they are not available on my desktop. Some very talented dukes there...and some great work...never seen making tongs so easy looking.
