The Test Bed

I know, I know, it's been a long time but one thing leads to another and before you know it...

I have a whole week of annual leave to squander on my little boat and so far I have been blessed with lovely sunshine. Yesterday was spent with a sander in my hands, there will be further sanding, filling and fairing before the hull and keel are up to scratch.

Today I conducted a test, having spent time over several months gathering materials and equipment necessary for vacuum bagging. I converted my pressure cooker from the Red Admiral days in to a catch pot with vacuum gauge...


...the handle on the lid snapped off on my return from Newport so I'll be needing a replacement!

I've taken a small sample of the G-PET foam core I bought months ago and laminated a piece of 600 gsm biaxial glass cloth to each side of the foam using Ampreg 20. The resin has a fairly long open time, giving you the breathing space to work with larger pieces before it all starts to gel.

There's a leak somewhere in the system, with so many connections I'll have to chase it down and I'm pretty certain it's not within the vacuum bag itself?!


So far so good, at least what I can see of it looking through the vacuum bag, breather, peel ply etc.

I'll know either way come the morning...
