This is the continuation of the Thread on "Building Peterson's Schooner "Susan"... this is the 12th separate thread in a continuing series.
Here are the links to previous segments on this thread.... Note.. a few of the threads in the first 4 segments are missing some images because SonyImagestation closed down... and I did not redo the image links. Segment #2 and #3 are particularly missing links.. .. I have a pdf file about 80mb in size (consists of segment #1 thru #6) that I can send you if you send me your email address via pvt message..... I can send it via www.yousendit.com

This segment will begin with the pouring of the keel, which is approximately 4,500 lbs.
First I thought I'd show the mold which is used in the casting process. This mold was reinforced and coated on the interior to withstand the hot lead better. See previous thread for these details.
Now here is the basic setup with the female mold in the hole in the ground, with doubled chains on both ends to enable the keel to be lifted out of the ground after casting. The ground was leveled here with a bag of cement dumped on top to make for easy minor adjustments for setup. The tank was purchased in a scrap yard and is constructed of 1/4 " steel. The hole cut in the top is wide enough to throw in lead and the cut out plug will be used to close her up while heating the lead. Its important during the melting process to minimize the loss of heat from the tank. The height of the tank was simply set up so that when the pipe was rotated down it would be placed precisely where the the molten lead needed to pour in via gravity.
The mold closer up. NOTE the 1" wood dowels precisely located and locked into place to produce holes for the one inch threaded rods that will hold the keel to the hull. The bottom of the wood dowels are set in a small wood block that will end up producing a recess at the bottom to fit the large washers and the nut at the bottom of the keel. See following photo to see this...
Working on the setup... she's coming along...
Almost there.... fire to build soon...
More setup... the tank filled with purchased lead and billets Bob had molded over the past few years...
