Here's the latest...
I popped the mold off of the master plug last night. In hindsight, there are a couple of things I would do differently. The main thing would be a second coat of gelcoat. It's a bit thin, but there is only one spot I can see that may need some "work", so it shouldn't effect anything. The other would be to possibly not use the Partall mold release on the master, and just use a releasewax only. The mold did come off really easily though, so I can't complain. Overall, everything looks good.
Here's some pics to bring the thread up to date...
Since the last pics, I added another layer of 13oz. cloth...
...followed by a layer of mat...
...cured, sanded "sharpies" and scuffed...
...added one more layer of cloth (not pictured) and a final layer of Coremat...
This was my first time working with Coremat. It sucks up a lot of resin, but adds good strength at a relitively light weight. It doesn't like sharp contours though. I may lay some up in a seat at some point.
Here's the mold, all trimmed up and ready to produce the first seat...
The plan is to make one seat as it is, and see if the mold needs any cleaning up. There is only one small void that I can see needs work right now. It can be sanded off once the seat is made. Should have another update later this week.
