Brief Description: deburr holes in spars, construct jig
used scotch brite pad rolled up to de burr lighting holes in spars (worked ~OK) cut out HS Jig Cradle Blocks - used extra piece of plywood cut on top of original jig board. Cut one by it self and realized that it may not be close enough to be able to level.
