Hellgap, thanks for the kind comments, on the mammoth use sharp belts slow your grinder down, I don't go any finer than 220 belt, finish from there by hand. Mark thanks for the comments, I put scotch tape on the blade so it is protected from scratches, super glue a piece of micarta the full length of your formed halves so you can hang on to it and it will keep it from warping from the heat from grinding, cut out a set of liner material that you are going to use and fit the sheath to the blade, use new liners to finish, these will have grit in them hopefully it will hold it't shape when soldered. I line my sheathes all the way to the bottom, use two pieces on the sides and two for the flats, i use an old thin machinist rule that have done some grinding on do the sides first, use double stick tape to put the rule on the liner use contact cement don't let it dry and slide your pieces in, it takes a day or two for the glue to dry. If it all goes to pot fill it with lacquer thinner and start over, hope this helps. Deane
