Right. So you have you scales roughed out. Now it is time to sand those edges. I start with a 240 grit wet/ dry sand paper. Using it dry, just sand the heck out of those edges to remove any scratch marks from the sanding drum. once this is done I move to 600 grit, then 1000, then 1500. Like sanding the blade, don't move to the next grit until all the scratches from the previous grit is gone.Next you want to drill a 1/16 hole where the blade is to be pinned. Now IMO this is the ONLY part that reallya power tool. All the other parts can be done by hand if you are patient. But if you do not drill this hole perfectly straight your blade will not travel straight in the scales, and it will probably catch the edge. You need a drill press. One possible alternative is this attachment for the Dremel. It is not very heavy duty but for this sort of small work it is fantastic and takes up very little space.Wedge time! Take a piece of acrylic that is a bit bigger than you need, and sand its sides while putting more pressure on one edge than the other. Keep sanding until the plastic becomes a wedge shape. One trick, if you are brave, stick the wedge to your fingers using double sided tape and use an electric sander. This works, and is much quicker, but not necessary. Do NOT do this with a belt grinder! I have one flat finger tip which explains why.Sand and polish the wedges widest edge (the one that will be next to the blades toe) now, you will not be able to get at it once it is in place.Separate the scales and remove the paper from the inside. Put a 1/16 rod (the one you will be making your pins from later) into the pivot hole to keep them even. Using two part, 5 minute epoxy give your wedge a thin coat and glue into place. You will have to experiment with using stands, levels, props and other things to keep it all in place until the glue dries. Normally I would just clamp it but the wedge shape means that the wedge is always squeezed out of position by the clamp. Make sure everything is square and in the right place. If you put these three pieces together out of position, even by 1mm, the blade will not centre properly. Check it three times before walking away to let the glue dry.Once the glue has set, back to the drill press to drill the hole(s) for the wedge pin. At this point I like to put small micro fastener nuts and bolts into all the holes and tighten them down. This holds it all together for part three...
