Nice progress.. Sanding is a shitty job and fibre glass work is not for ryobi etc. I have a makita sander that has done 3 boats

Also started glassing the nidacore sheets - this was my first attempt ever at fiberglassing anything!

It turned out alright for my first attempt I think...

On the nidacore sheet I used 410gsm Biaxial woven fiberglass sheeting, the stuffs a pleasure to work with - literally no stray fibers or mess! I used approximately 2250g of resin plus 2% catalyst per side of sheet.

I also put peelply over the wet glass - I doubt I will be doing this for the remaining 9 sheets ( works out to 95 rand a sheet) the idea behind it is that after you peel it off once dry it imparts a rough finish into the resin so you do not need to sand it down again when you need to apply another layer of glass after you cut the sheet into whatever it needs to become - bulkhead, stinger, deck etc...

Tip : when mixing the resin and catalyst I used a cheap electronic scale I bought at Crazy Store to get an accurate ratio of resin to catalyst ( I added 2% MEKP as it was an average temperature and I was working in the shade).

For application of resin I used a big yellow spatula thing to spread the resin over the nida sheet evenly and an aluminium roller to roll out any air pockets and to make sure the fiberglass adheres to the sheet nicely after application. Both items available at the composite shop AERONTEC.

Sorry about a whole lot of boring info but hey maybe it helps someone else 👍🏻

Thanks FS, I agree 100% it's a shitty job and definitely not for the likes of ryobi..

Use a mo hair paint roller to apply the resin on the nidacore. Also try covering the nidacore first with just resin and let it set. Then put the cloth on. The nidacore gets too heavy when you press the resin through the cloth into the cavities of the nidacore. The cloth on the pic doesnt look saturated as i suspect the resin flowed through the cloth. Remember every kg of resin is a kg you add to the boat.. Just a tip that i found worked the best

So just an update on the build

The hull has been glassed with 2 layers of 450 chop strand throughout as well as 2 additional layer strips running along the keels.

We are currently busy with the transom - just needs to be glassed over tomorrow. Transom consists of 1 layer glass, 1x21mm marine ply section, 1 layer glass, 1 x21mm marine ply section and we will put about 4 or 5 layers of glass over all of that tomorrow with all of the above being in position.

The hull after glassing, can feel quite a difference in rigidity. She's solid now!
