Hey rc, is that the killer truck with the spring board for your swan dives?... no red on those discs...
If you used all your clamps, you obviously haven't got enough... even with the biggest job, you have to have at least 20 lying around unused to trip over and have something(s) to put away while waiting for the glue to dry.
BTW: Did you Parf those holes?
If your first cut is too short... Take the second cut from the longer end... LBD
