The propeller shaft hole will be drilled prior to sheeting the bottom. Two pieces of scrap plywood were screwed to the keel. Once the strut mounting holes were drilled, a stack of washers under each mounting hole was used to determine how much material had to be removed. (28-MAR-2005)

A jig was rigged up to flatten the strut mounting area. The router is run on two parallel lengths of angle iron.

Depth of cut is adjusted to remove enough material so that the strut sits flat on the plywood.

A block plane can now be used to finish the job.

A 1/8" masonite spacer was fabricated and slipped under the strut to simulate the thickness of two layers of fiberglass cloth which will eventually cover the hull. The strut was bolted into position and an 8' long piece of 1" round bar was fed through the strut to simulate the propeller shaft. (02-APR-2005)

Remove the shaft and insert the boring bar, coupler and holesaw into the guide block. Use an inclinometer to verify the shaft angle is correct before drilling.

This is a view from inside the boat. An 8' long shaft was fed through the strut and shaft hole. A 1" hole was drlled in frame #4 to position the shaft at 12 degrees.

A 1" ID x 1-5/8" OD rudder shaft collar inserted into each end of the tube will center the shaft in the tube until the epoxy cures.. When the boat is righted, the tube will be ground flush with the keel. Two laminations of fiberglass cloth will be applied to the keel before installing the shaft log.

Two layers of 3/8" thick by 2" wide mahogany stock were laminated to the inside chine log surfaces. This will restore some strength to the members, lock the frames into position and provide additionnal fastening area for the first plywood bottom screws. (04-MAR-2006)
