After everything is trimmed, I am ready to join the mold halves. To hold them together relatively tightly, with no investment in specializedequipment,one could use binder clips (available at a Staples or OfficeDepot near you).

#1 However, I did take a little bit of a plunge here and boughtseveral klecos and a pair of kleco pliers to hold my molds together even better. I ordered mine from FibreGlast. I think there are very much worth the investment. In fact, I only have enough to join one mold together, so I will need to order more of them.

I believe that klecos are most commonly used by the aerospace industry as a way of temporarily holding perforatedaluminum sheeting inplace on aircraftuntil replaced one at a time with rivets. (Is that right, Tommy Gun?)

#2 Here, I am trial-fitting the mold halves together to check if I can find anything hanging over the top or bottom of the mold and thuscausing too big of a gap at the seam. (Look through it with a bright light behind it to see the gap more clearly.)
