The first capsize rule is 'Don't!' Good seamanship is key, but you can also fit a fuse to release the sheets when a certain angle of heel or...
The 2:1 system I referred to above is "41% bio carbon", apparently the highest in Aus. I have no idea what this means (maybe 41% of what would...
Not sure where your info came from, but The WEST System data page https://www.westsystem.com/app/uploads/2022/09/105_205-207-Combined.pdf shows...
Not uncommon. The first thing to do with new pumps is to get 2 identical containers and pump 5 hardeners into one and 1 into the other (or...
A data point. The 6m barge in this video has 5 x 300W solar panels on it's roof, but only 2 are connected. The motor is a 40 hp outboard, with...
Absolutely. Weird really as the fibres take a lot more load than the resin can. Tane, you can still do this with most epoxies, but I would not...
It is less brittle, but we chose it primarily for it's long outlife and simple 2:1 mix ratio. I was prepared to sacrifice some mechanical...
Putting the screws in is the easy part. 5,000 screws at 20 seconds each is 29 hours. Rot proofing the holes is the tricky bit. All the screws...
If you calculate the amount of resin that will end up in the vacuumed laminate, there will be be dry patches in the laminate prior to applying the...
Way back when I was selling System Three epoxy in Aus I ran a design competition for an innovative boat. From memory, there were 50+ entries, many...
It's many years since I did a vac layup and I didn't measure the waste. However, it is difficult to wet out cloth at better than 1:1. A good vac...
Epoxy is not expensive unless you pay for the name on the label. I have just paid $US8.56/kg and $US7.12/kg for infusion and general purpose...
Mulkari, I like your thought processes. Keep eliminating expensive things and focussing on what you want/need and see where you end up.
I think you meant stiffness, not strength? A flat panel will generally take more load before breaking than a curved one, if it is able to flex...
Thanks. Not sure whether Derek is smiling or rolling! We certainly would not be where we are without his influence and input. The cargo proa is...
