I apologize up front...it's not a pleasure to be critical of any specific work. However, this work is on the front page and it's a good example of how
not to do this task.
Glass tape is generally a poor choice for layup. Look close and you find woven edges, with one edge being even thicker than the other. The thick edge creates a void when another ply is laid over top of it. Filling the void requires a lot of epoxy (i.e. a very wet layup). The alternative is an air bubble. Even in a non-structural part the air void creates finishing trouble.
The woven edges also lock the criss-crossed threads of the weave in relation to each other. If the threads can't shift a little the fabric doesn't conform to curves and shapes very well.
Last, a layup pieced together from many individual tape strips almost always results in a variety of thicknesses. So, the part requires a lot of filler, or sanding away a lot of the fiberglass fiber. Again, even for a non-structural part you're just making a lot of work.
This particular part seems to illustrate
A Great Sin of composite construction....built-in delaminations and voids.
I assume the goal was to overlay the base component. In this case the overlay could have easily been unbroken fabric plies instead of tape, resulting in no laps, no voids, even thickness, and much less finish work. The cut pattern would have been a large U-shape; like a dressmaker you merely cut a paper pattern to get started. I imagine ordinary 9oz plain weave would lay smoothly, and 8.9 oz 8-harness certainly would.
FWIW, I have still not used up the original rolls of glass tape I purchased from Wicks in the mid-90's.
Again, I apologize for singling out this particular example.
