    Two more pieces knocked out and I'm happy with them - of course they didn't play nicely (one worse than the other - more below).

    First thing was to lay up carbon in the big mold. It all went in nicely and like a dumb-ass, I missed two major things...



    Testing the vacuum - yes! It has a full pull, no leaks and is ready for action:



    Resin introduced into the system - notice that you can see the carbon under the green mesh? Uh... not supposed to see that. There's supposed to be a layer of peel ply under the infusion mesh. I realized this when I went back to check on progress about two hours after mixing and infusing. Too late to do squat and will have to deal with it when it's all set up.



    So, guess what peel ply does? It's a release agent. It keeps the mesh and vac bagging from sticking to your part. No peel ply, shit sticks really well - heck, it's epoxied into the part. Here's when I first started trying to see if the stuff would come off.



    Nope, it doesn't come off - so here's the piece all cleaned up and with as much of the extra stuff off of it that I can get. Fortunately this is an underside so if you don't know it's there, you're not gonna see it unless you're crawling around looking for stuff. I don't think most people would know it's a screw up - I'm gonna say it's a special scatter shielding material if anyone asks.



    So, wanna ask what else went wrong? Sure you do! Go ahead, ask...

    My dumb-ass forgot mold release. It's just brushed onto the mold, nothing special, what have you - just a white liquid that you brush over the mating surface. Did I use it? Nah, of course not!

    Know what that does? It pulls all the primer off of the mold and leaves it stuck to the part. SO very glad I have a set of plastic wedges just for removing stuff from molds. Took a bit of work and a lot of swearing at the parts to get them to let each other go. End result is a nicely molded shroud all covered in primer. Shit.



    Fortunately it cleaned up really well with a DA sander and some 400 grit. I actually like the sanded look versus clear coated carbon.

    The three aluminum inserts will get some sort of pattern punched into them. The smaller rectangular piece was my first attempt. Trying to hold something thin like this in the vice can be sketchy at times - this was one of those times. It moved on me. No biggie - didn't like the lack of detail in the honey-comb cut outs that I saw anyhow. It's a simple part and I already have a new one made.





    Did not like the way my two molds came together. The main clutch cover area panel fits well, looks sweet. The oil res cover, on the other hand, doesn't blend worth a shit, looks cobbled, didn't come out like I saw it in my mind's eye. This was mentioned in my last post.



    Out with another mold - it fits much better and also blends into the main panel nicely. I was able to use the first one as a pattern that worked out really well.

    New res mold next to the first attempt:



    This time, before starting cutting carbon and such, I pulled out the necessities of release the VERY FIRST THING.



    Carbon, peel ply (upper left) and the mold all set up for assembly.



    See how you can't see the carbon through the green infusion mesh? That's because Dumb-Ass (me) used peel ply this time.

    Infusing in action:



    Check this out - this is why we use peel ply. It comes off in one nice piece, leaving the clean carbon underside. Yay.



    Mold release also makes a big difference. Obviously I didn't get it completely coated but the res cover popped right out and didn't bring all the primer with it like its big brother did.





    A little more sanding and it now has the same surface as the large piece. Here are the two screwed together:



    Both parts in place - working on the mounting tabs now.



    This blend between the two pieces looks SOOOOO much better than the first cobbled setup, don't ya think?



    Done for the day. Will get the mounting tabs installed in the next day or so and see what else there is to check off the list.

    I'm thinking door inner panels are next.

    Thank you. I’m digging the matte finish.

    Dash... It’s sitting dejectedly on the floor, out of the way. Every time I walk past it, it taps me on the leg and looks up at me wondering when it’ll receive some love. Soon, my friend, soon...
