:facepalm:
Talk about chicken chit welds. :eek: Looks like you used bubble gum. :shakes head: You have to start somewhere. The more you weld. The better you get at it. You just need someone to show you a few methods on how to move the weld puddle to smooth out the weld. You pushing or pulling the puddle? And are you using a steady motion (looks steady to me with a nervous tick), or stop and go? Always practice on a piece of scrap before you weld your parts. Before you weld. Get yourself in a comfortable position. Hands supported. If not. It will show in your welds. |

I think the welds look 100x better than what I could do. All I can reliable do with a torch is burn holes in something. :eek:

Good news! Popped my hood from the mould and it's going to be useable! I have a few problem areas but I honestly anticipated A LOT more. Everything can be repaired and I have the tools. Next mould will be a lot easier due to some of the pain points on this one. Carved out pin holes and detects with the grinder. Now I can build it back up. ... A different night. -------------------- Extra info: The PVA that was used on the hood created a crazy static charge. When I popped the hood from the mould with my buddy, we got shocked... It felt like we got hit by 110. Actually, I should have gotten pictures of the PVA coming off because it was awesome to see it pull out of the mould. Breaking the hood from the mould was pretty wild. Dave put a couple plastic pry tools in a corner while I went beast mode breaking the hood free from. when it released there was a huge * POP *. Not gonna lie, I was pumped off some anxiety when it released. I was expecting it to be WAY worse. I sent the same pictures to a guy I know that does carbon fiber and he wasn't put off from any of the pictures. He was like, "Yeah, that can be fixed in a few days no problem." Only issue I see is doing one corner. everything else can be blocked easy(ish). The edge of the mould will not be part of the hood. I just need to get it filled. Cut extra flange off https://bsnqaq.dm.files.1drv.com/y4m...&cropmode=none https://bsnpaq.dm.files.1drv.com/y4m...&cropmode=none https://bcnhaq.dm.files.1drv.com/y4m...&cropmode=none https://bcniaq.dm.files.1drv.com/y4m...&cropmode=none https://bcnkaq.dm.files.1drv.com/y4m...&cropmode=none https://bcnmaq.dm.files.1drv.com/y4m...&cropmode=none https://bcnlaq.dm.files.1drv.com/y4m...&cropmode=none https://bcnoaq.dm.files.1drv.com/y4m...&cropmode=none https://bcnpaq.dm.files.1drv.com/y4m...&cropmode=none https://zslkdg.dm.files.1drv.com/y4m...&cropmode=none https://zslndg.dm.files.1drv.com/y4m...&cropmode=none https://zslmdg.dm.files.1drv.com/y4m...&cropmode=none https://zslpdg.dm.files.1drv.com/y4m...&cropmode=none https://zslodg.dm.files.1drv.com/y4m...&cropmode=none |
This is a really great thread.

The GOAT, @cjmotorsportsinc ,of fuel systems anodized my FPR. It looks awesome and I like how the Aeromotive is shadowed. �� Man, this is going to be a lot of sanding. ------------------------- MAN, you have no idea how much that means to me that a few of you guys enjoy going through some of these pictures. They really are a PITA sometimes to get. Also, it’s a real kick in the nuts posting some of the fails that go hand and hand with being new at doing this. If seeing these pictures helps someone somehow then it's worth it. Having a cataloged path of completion is pretty cool to have on a build is pretty rad in the long run. IG comments summed it up what is happening well. I see lots of sanding in my future. The good news is that I have some nice sanding blocks and can chew through the high spots easy. Worst case scenario for this mold is this: I don't do a beauty layer of carbon fiber later. I can do two layers of CF with the mould and then do a wet lay up over the vacuum infused part. I don't anticipate going that route but it's nice to have a plan B. Maybe I should do a better job explaining what is happening in pictures... The perimeter of the mould had some dry fiberglass issues. I cut all that out previously with trusty death wheel. I filled in the pockets with fiberglass. The high up perimeter isn't terrible important because I can sand that back to the flange no issue. I just needed something to sand back for a transition from the mould. The inner part of the mould was filled with tooling gel with a mixture of wax. The wax is needed so that the tooling gel can cure properly. Tooling gel is typically sealed off by the fiber glassing process and cures that way. Normally, people make a mould that doesn't suck so bad and can pop off a perfect mould. My inexperience shows you the long road.... yay... Also, Charles/Phunk anodized my FPR. Me being me, I marred it up within a few minutes putting it on with a big *** crescent wrench. https://ainlaq.dm.files.1drv.com/y4m...&cropmode=none https://ainnaq.dm.files.1drv.com/y4m...&cropmode=none https://aynmaq.dm.files.1drv.com/y4m...&cropmode=none https://aynoaq.dm.files.1drv.com/y4m...&cropmode=none https://aynlaq.dm.files.1drv.com/y4m...&cropmode=none https://aynnaq.dm.files.1drv.com/y4m...&cropmode=none https://aynqaq.dm.files.1drv.com/y4m...&cropmode=none https://aynpaq.dm.files.1drv.com/y4m...&cropmode=none https://ainiaq.dm.files.1drv.com/y4m...&cropmode=none https://ainhaq.dm.files.1drv.com/y4m...&cropmode=none https://ainkaq.dm.files.1drv.com/y4m...&cropmode=none https://ainjaq.dm.files.1drv.com/y4m...&cropmode=none |
I really do enjoy reading on what you are doing. :tup: Brings back nightmares of me doing some of the this. Best of luck to you with this project. :tup:

Started in on sanding the hood and let me tell you this, tooling gel gets hard AF! I started off with my 400grit sanding block and quickly went down to 60. You are looking at 3.5hrs of sanding. There's a LOT more sanding to go as well. I'm going to try doing some surgical hits with the death wheel tonight to reduce arm fatigue. I will also need to do a skim coat in almost all the areas and do another knockdown with fine grit. Eventually I will make it up to 1500 wet sanding. Last step is polishing, distant horizon at this rate. Like I said, this mould is workable and will take a lot of work.
If anyone is curious about the weight of the mould, the weight is around 75 -100lbs. lol This Saturday I'm going to start in on making the cowl. I'll need to come up with a bone structure made out of wood. It will look similar to the cardboard structure I made previously but have widths as well as height. The wooden structure will give me stop points for my tungsten carbide sanding block. Cardboard will sit around the wood structure and on top while it is sitting on the hood. This will allow the foam to take the shape of the hood, encapsulate the wood structure and then rise up to the top of the cardboard. Relief holes will be cut into the top of the cardboard so that the expanding foam doesn't bust through like the Kool-aid man. The cowl needs to come in close to perfection. I'm glad I started with my hood and have worked through all the repairs. I've seen with my own eyes and connected the dots why certain aspects went well and other items turned out like garbage. Most important of all, I've always wanted to make a meaningful composite part stretching myself into new areas. Honestly, I can't suggest starting on a hood. Personally, I go head first into projects so it is what it is; however, I think that's been well f*cking established how far I'll go off the beaten path. Good thing I have the hood because I am currently waiting on my order of wastegates, blow off valves, couplers and v-bands. The wastegates, BOV and couplers are all VSRacing. VSRacing recently had a design change and look REALLY nice. The shop bought a few for a twin turbo sandrail and was able to inspect them before I ordered. Vband clamps... That has got to be one of the biggest kicks to the balls. Ordering a handful of clamps was a rude awakening. Guess my post is a little bit wordy today yet needed. Hopefully you can see the same path forward as I'm seeing. https://acnkaq.dm.files.1drv.com/y4m...&cropmode=none https://acnjaq.dm.files.1drv.com/y4m...&cropmode=none https://acnmaq.dm.files.1drv.com/y4m...&cropmode=none https://acnlaq.dm.files.1drv.com/y4m...&cropmode=none https://acnoaq.dm.files.1drv.com/y4m...&cropmode=none https://acnnaq.dm.files.1drv.com/y4m...&cropmode=none https://acnqaq.dm.files.1drv.com/y4m...&cropmode=none https://acnpaq.dm.files.1drv.com/y4m...&cropmode=none |

Less text, more boost noises!!
Looking good man. Cool to read about a different kind of fab project than normal. |
