I thought about doing it that way first. It does gove you a much smoother surface finish when you take the finished cowl out of the mold since you are starting with a nice smooth finished cowl. The reason that I decided to do the male plug is because I can make a plug or two now and store them. Later when I have the engine installed it will be easy to add any bumps or humps to the plug that I will need before I lay the carbon fiber up on it.
I was going to make a one piece cowl then split it with a cuting disc. Then I will sand the inside of the bottom half near the joint and put packing tape or mold release on the top section. I will put the two halves together and use some 2" tape to lay up the joggle area so it will be a perfect fit between the halves. Any comments or suggestions to this method?

The resulting parts look fine. I recommend you pay particular attention to the joggle where the two halves join. Ross has seen the mold and resulting parts I built. He thought it looked pretty good. It sure was easy!

Anyone ever done this before? _______________________________________ to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
