Hey Doug,Is that "special resin" still an epoxy or maybe vinyl ester? Does that particular carbon fabric require vacum bagging to conform to the mold properly or will a more conventional wet open lay-up work? Cool stuff.
Thanks for the great advice Mic. It is appreciated. Yes. The resin for the mould unfortunately is very expensive because of non-shrinkage capibilities. So it will be expensive but right. The quality of the mould will also be superior and more bodies can be pulled without damage. So I will go for that resin and the specs for the fibre glass for the mould. The bagging I will have to really work out carefully. I'm considering getting more plastic and cut it up for smaller areas, basically bag in a bag.... but I will really think it through before I get going and take the big step. I do have alot of time still so hopefully it will be as clear as water by that time instead of as clear as mud at the moment! :laugh:If you decide to go to epoxy and vacuum bagging it's advisable to think really long time before how you will engineer your molds (as written before) and also
how you will do your flanges molds in order to avoid to do too big vacuum bags that will include all mold and laminating!!
Again if you decide to built large flanges around the mold you need to use specific fabric and resin to do your mold ; if not they will leak thru the wall thickness and your vacuum bagging will be poor or desastrous
using vacuum process gives a nice good part when done properly and hawfull ones when all the process is not applied correctly
In your case ; don't worry there will be so much to do that when you will be in front of complicated parts your expertise will be ok because of so many simple parts have been done before !
Be aware too that vacuum molding needs to be at least in 2 people minimum !!
( and remember wifes are much more patient than us in closing carefully the bags and doing leaks cherch LOL)
:laugh: I really have no idea and because my welds looks like sheep shit, a friend of mine is going to do the chassis for me. His trade is welding so cannot go wrong there! Just wish he wasn't so busy at the moment so that he can get started!Nice! What are you going to construct it out of? One thing I found when I was cutting and welding tubing for a chassis was the outside dimensions ERW steel tubing is very uneven. Making it necessary for each piece to be custom fit to make the end result square and even. Next time around I would like to get my tubing laser cut. I figure to make this work the outside dimensions of the tubing must be completely uniform though. I can see why ERW tubing would be less than uniform because of the welded seam. Is DOM tubing more uniform in nature? I'm thinking I'll use 4130 for most of it.
