MAST LADDER FRAME

The plans set out a number of stations along the masts where square spacers are used to ensure the accuracy of the taper during glue-up. Of course the location corresponds with the marks you've already made while setting out the taper, so it's a pretty easy process. To save a bit of time if you coat the inside face of the timber with epoxy and glue up while it's still wet or tacky.

Sticky tape makes a good clamp, but staples or panels pins that can be removed later will hold the slippery little suckers in place till the clamping pressure can be applied.
