Once the spacing and alignment is correct, you can glue and assemble the mast. Nearly any glue seems to work: TiteBond II or III, Gorilla Glue, epoxy, and PL Premium have all been used successfully.

Some people have suggested a trick to help minimize glue runs: When you get the spacing and alignment right, but before you apply the glue, wrap the mast up, then run a line of tape along the OUTSIDE of each seam (except the last seam, of course.) Unwrap the mast, apply the glue, wrap it back up, and then run a line of tape down the last seam - that will keep the glue from running all over the exterior of your mast..
