I searched "daggerboard, green, strip", this morning, and got as far as yesterday's posting.If you search for daggerboard, green strip in this forum I posted a picture of my daggerboard.
The pumps sorta worked the first time, then went downhill in a hurry.You need a digital scale to get the epoxy mixed correctly. The pumps used in the West System are crude at best. Excess heat is usually caused by too much hardener but ambient temperature
also plays a role. The #105 epoxy resin is mixed in a 5:1 ratio with the #205 and #206 hardeners, and a 3:1 ratio with the #207 hardener.
I’ve never had trouble with West pumps. I’ve found them to be reliable.
They do work to get
you in the ball-park so to speak but using a digital scale will save you wasted material
and money in the long run.
If you remember your chemistry class any deviation from mixing the exact ratio of chemicals does nothing
to help the reaction and just wastes expensive chemicals.
I did not mean they they don't keep pumping, I meant that you can't use them to
measure out a accurate amount to provide the correct ratio.
1965 James Bond Thunder Ball. Movie had it all, underwater diving fights, skimpy
clad women, hydrofoils for the bad guys and a swimming pool full of Sharks, not
Sea Bass with lasers strapped to them. I miss SPECTRE the Red Menace, things have
not been the same in movies and novels since the Berlin Wall fell.
A common mistake of those using epoxies. It's a molecular matchup and any excess of either is just waste. This thought I'm believing, comes from adding extra MEK to polyester resins...which WILL make it "kick" faster.If you remember your chemistry class any deviation from mixing the exact ratio of chemicals does nothing
