Starting the skin: the bottom part

A large roll of back PVC has been looking at me for weeks. Now it was time to unroll it.
Working with PVC requires a large flat table. And a large flat table requires a lot of space. So some serious ordening was necessary in the shed. All bicycles that are not used on a daily basis have been moved upstairs or hung from a wall. Four sawhorses together with two old hobby tables from our former house make a table of 0.8 x 4.3 meter. Five meter would have been better, but this should be OK.

First action is cutting a blank of approximately 5x1 meter, and marking the centerline with tape on both sides.
A disadvantage of the black material is that is is difficult to mark. The paper tape works nice, and a white pensil from the kids works somewhat. On light colours you can use permanent markers, on the black you hardly see those.

The blank is put onto the skinning frame, and clamped at bow and stern.

Using paper tape the gunwhales, chines, bow and stern are marked on the blank. Also the trim line is marked, 50 mm below the gunwhale.

Back on table the blank is trimmed to size.

For cutting I use Black and Decker elektrical scissors. That may seem lazy, but that is not the point. The elektrical scissors give you the possibility to cut the material hardly lifting it from the table and without any movement, so you can cut very precise. I started using these with carbon fibre, and for that it is a godsend as it prevents tearing out fibres. For PVC it works like a charm as well.

The final result.
