At this point the instructions are a bit out of date. They call for wax paper over the plans. Parchment paper works better. There is a layer of painters plastic and a sheet of parchment paper over the plans. You can see the degree of transparence. It works well protecting the plans and the work bench. The next three images are the rudder and fin constructed with magnets. The techniques used to construct these parts were suggested in other build threads. The cross members were cut just over size and sanded to fit. This worked well. The ca did not stick to the parchment paper. To keep the shop warm there is a small propane heater with a fan sitting on the table behind it. This combination stirs the air enough to blow the fumes away. No problem with the ca fumes attacking my eyes. The fan is a must when using ca.
