Step 1: Gather your materials
*****UPDATE ON GLUEUP****
straight acetone works better for glue up of plexiglass, not to mention MUCH MUCH CHEAPER THAN CA adhesive...
just make sure you clamp it good.
Step 2: Cut your scrap pieces to uniform size and glue them together.
Now glue one of the scraps between two other pieces of scap, to make three layer scrap sandwich. Do that twice and let them sit...
Step 3: Sharpen the blade
Step 4: Now glue the handle pieces to the blade
Step 5: Shape the handle
I shaped the handle on my belt sander to a rough shape then cleaned it up by hand with some 80 grit. After the shape is nice and the way you want it, wet sand the handle all the way thru 600 grit.
