Beveling the Stem

Tom beveled the stem and it turned out beautifully. It has been marked with stringer, sheer clamp, and station locations. This is a substantial piece of mahogany and it will add so much in terms of strength and beauty to the boat.

The Bulkhead Frames and the Transom

Trimming the okoume to size on the bulkhead.

The router's flush cut bit does a fine job of trimming the okoume to match the frame.

You can never have enough clamps!

The Oukoume came in from Edensaw Lumber so Tom was able to attach it to the bulkhead frames and trim it to size on the router. Then, using African mahogany, he started building the transom using lap joints. Next, the transom will be shaped and completed.

The Frames

The frames are the forms that the boat will be built around. They support the stringers which are longitudinal strips of wood that the planks will be attached to. Tom completed the temporary frames and will complete the bulkhead frames when the plywood comes in on Tuesday.

Continuing with the Stem

Tom completed the routering and then laid out the bevel lines on the stem. It's very important when building the stem to make certain that the rolling bevel meets up exactly with each individual plank. The next step in the process is doing the actual bevel.

Building the Stem

The stem is made up of six 3/4" pieces of Phillipine mahogany. There are three lower stem pieces and three upper stem pieces. Tom started work on it by first laying out the six pieces using the template and then rough cutting them on the bandsaw. The upper and lower pieces were then epoxied together making three pieces. The template was then attached to the center piece and used to trim the stem on the router to shape. The three pieces were then epoxied together. Next, the center piece will be used as the template by the router to trim the outer pieces to match.

Making the Templates

Tom was excited to get out to the shop and start building. He started by making the templates for the stem and the transom out of 1/4" plywood. These templates will, in turn, be used to build the actual mahogany pieces.

The Wood

Okoume plywood, often called mahogany plywood, is an African hardwood. It is light brown in color, sometimes lustrous, with variable interlocked grain. Okoume panels exhibit high strength to weight ratios, ideal for boat building. Face veneers are 2.3 mm thick, A/B grade, and rotary cut. Cores and crossbands are solid jointed and panel glued with waterproof/boil proof glue. Marine grade okoume meets or exceeds British Standard 1088. Okoume panels are extensively used by race class boat builders, rowing shell builders, and in various applications where its light weight, high tensile strength, good bonding properties and ease of finishing are of value. On this Penobscot, we'll do the hull planking, bulkheads, and transom in okoume.

All of the interior wood will be either Phillipine or African mahogany. The Phillipine mahogany is a beautiful honey brown when finished and will match the okoume planking nicely. It will be used as structural lumber to build the hull, the longitudinal stringers, the stem, the bulkheads, and the keel.

African mahogany is a deep, rich, burgundy-brown which will compliment the more subtle interior tones and be a stunning contrast to the white exterior. It will be used for the seats, gunwales, breast hook, and quarter knees.

The deadwood will be of white oak which is an excellent boat building wood. It is very tough and takes fastenings well. Due to its closed cell structure, which inhibits the intrusion of water, it is ideal for the one piece of wood on the boat that will remain submerged during normal use.

The combination of okoume, Phillipine mahogany, and African mahogany on this scale will be beautiful.

Our local lumber supplier quoted a four week delivery time for the okoume, so we contacted a well known boat lumber supplier in the Northwest--Edensaw Lumber in Port Townsend, Washington (www.edensaw.com). They did have some on hand and it should arrive within three to four days. In the meantime, we purchased the mahogany and the white oak as well as some pine for the frames and the building jig from High Desert Hardwood in Eagle, Idaho.
