Can anyone help me with making new transformers from scratch/existing figures? Materials/methods?

1.Scratch building
*Which is better to use, pla plates or styrene? Any other suggestions?
*I found this website on how to make moving fingers/hands for gundams (http://mxgs.blogspot.com/2010/04/scratc ... hands.html). Is there other ways to do this?
*I found ball joints on hobbylinkjapan.com and I was wondering what types would I need to make a transformer. I couldn't find any that would allow for 90 degrees or more bending.Are there other websites/brands that make parts like the ones on hlj? Is there a way to make them from scratch? How do I make friction so they are not loose?
*What's the best way to make hinges for doors/knees/elbows? I don't know how to make friction on these eithers to stay in any place I put them. Also, where can I find the same king of pins/screws they use on transformers figures?
*Has anyone ever used magnets in place of snap connections to keep transformed pieces in place? If not, how do you make the different ways to snap pieces together and not break?
*Does anyone know how to make those ratcheting joints?
*How do I make funtioning wheels that spin?
*What's the best kind of paint that won't wear off easily and can be airbrushed and/or can be hand painted without leaving streaks if airbrushing is not possible
*Can anyone explain how superglue fixes loose joints?
*What ways can you make a articulated combiner?
*Alumilite has dyes that colors the plastic that comes out of the mold. Is it better/easier to color the pieces this way or should I paint them with regular paint?
*Just any suggestions/books/websites will help
2.Existing figure
*How do you remove/reinsert the metal pins without harming the figure too much? That includes the wheels.
*What glue/paint sticks to the figures best?
Thanks in advance for any help
