So a a bit of an update.
Well today was core day, at least for a little bit. I managed to get the core in the outer wings in and covered with a layer of 1708.
I picked up a vacuum pump a few weeks ago for this, as well as a few other projects I have in mind later.
So being the cheap *** that I am, I had read that using drop cloth for bagging film works well, so in my head I thought " if drop cloth works well, vapor barrier has to work even better......"
IT DOESN'T, the bagging tape doesn't stick to it very well, I did a few a tests in the garage and it seemed alright, but when it came down to it the tape didn't stick at all and I couldn't stop the vacuum leak. By the time I realized it I ran around to grab some weight to throw on the core. Needless to say I have a few spots that will need to get drilled and back filled with resin.....
So after screwing up the entire one side I decided to go with a smaller section of core and try again with the heavy duty drop cloth. Worked great, pulled vacuum almost instantly.
Here is the screwed up side, you can see the layers of duct tape I was using after in an attempt to seal the bag up...... STUPID.
Here is the first small section of core I did after. I just took a piece of vapor barrier, rolled it up, stabbed a load of holes in it to make a bleeder layer and used a rag as a breather. I didn't care to suck all the extra resin out, just wanted the core stuck down.
I bedded the core into 2 layers of 2oz. CSM, then bagged it, and before I left for the evening I put a layer of 1708 over the top, because I am working on the boat outdoors and they are calling for rain in the next few days.
I ended up getting both wings done, but by the time I had everything cleaned up I didn't think to take some pictures.
