Tutorial video 1 https://youtu.be/mCjjmedF33Q


In this video, I have summerized the starting point of your sheet metal skin making process. The tools you need are a sandbag and a nylon bossing mallet. Using the back part the mallet, which is a rounded shape, hammering the center of the skin really hard in order to stretch out the center.

This video shows after you stretching out the center part, in order to get a curved shape, you have to use the different mushroom dollies depend on the sizes of you metal and a wood hammer with a flattened head. 
 
Tips: The right hammer is really important, it will save you a lot times while you are at the right track. Because the curved shapes are more fragile that any other form, you have to avoid using iron hammer or Nylon bossing mallet. The ideal hammer would be the wood one with flattened head.

In this video, I've show you some basic techniques while you are forming the skin. At the beginning, a good start would be bring down the edges by the wood hammer in a gentle way. You would like to avoid hammering the center part. You have to keep hitting the edges in order to achieve a ideal and beautiful shape. The other important thing is worth to notice is that when you cut the metal, do not cut it through every time. You wanna cut it carefully otherwise it would leave some ugly edges. If you have the ugly edges while you are hammering the metal, it will have some cracks between the metal. 
Please stop hammering immediately and then cut out some edges around those cracks, otherwise it would getting bigger and damaging your model in the end and you have to restart it all over again.  


Experiences that I have learned from this course:

1. Always start earlier, do not leave things until last minute. You wanna find out what model you wanna do at the beginning of the semester. 

2. The skills do not just comes along. You need to learn it and perfected it from different times of experiments. This is why I say you should start early. The sheet metal requires time to do it.

3. Always ask questions from your tutor or other stuff from the lab. You will help you understand some basic techniques and solve many problems for you while you are overwhelmed at the first place.

4. Good luck and have fun!!
