Making Putty for Building Skiffs

Here is how I make putty when building skiffs. To learn more about my skiff kits or Spear Boatworks, head to SpearBoatworks.com

for those with a scale, weigh the resin prior to mixing, calculate the total amount of catalyst. weigh the putty after mixing and divide the total catalyst by the weight of the mixed putty. this will give you a % catalyst to use. then life is simple. put 1000g of putty in a cup, add 13.5g of mekp. (example) when its hot, you bump the % down, and when its cold, bump it up a tad. harry makes wonderful boats and is a blessing to the skiff/fishing communities.
