Hi

You say that you want to infuse the part, right?

so you wont be running the pump for long.

Pump will only be used for removing the air and then keeping negative pressure as you infuse, once infusion is complete you simply clamp off the pipes.

Yes, it is a Honda spark plug cover. I did think it would be hard to copy, so I've set my sights a bit high, I guess? Got a few ideas on how I will do the mountings, but need to perfect the infusion process first!

I'm totally knew to composites, and it's been a steep learning curve, but I'm thoroughly enjoying it so far. I just wasn't sure on a few things with the infusion side of things, the pump timing being one of them, but thanks to you guys I feel a bit more confident now! Whether that confidence crosses over to practical side of things, is a totally different matter!!!




cheers 🍻 

Infusion should work the best. I can see wet lay and pre-preg being difficult on this shape, those mounts are problematic. You will just want to really make sure that there is no bridging in there, that will be the most challenging part. 

I have a feeling I'm going to be moving this onto the resin infusion topic area!! Ha ha

Seriously though, I think I'm going to try a couple of "dry" runs with a single piece of CF and an infusion stack, just to see what happens, but I need to wait on my diy silicone infusion connectors curing, and that looks like a few days of waiting! I know they are cheap, but if I can make 'em, I'll be well chuffed !!

If you have a few days its worth watching the EC video that Paul made showing the infusion process, will help with the questions you asked about vacuum times.

Id say as a beginner you will have better results if you clamp the vacuum pipe off first and then after letting extra resin in clamp the inlet pipe, give it 20seconds or so and if you have any bridging this will help.
