Annapolis barrelback 19

Post by benpetre »

Hi all,

I have been away from my build for 2 years due to a move, work, etc. I am now back into it and need to order some mahogany. Was planning on getting 1/8th in thick by 5-6” wide planks as long as they will make them for me. Anyone have any idea how many board feet for the hull and deck? I can’t seem to find my plans after the move. Will be relying heavily on the forum! Should I get all the mahogany now, or buy in stages when needed? Will it be a better color match if all at same time?

With 5-6” wide planks, you’ll need about 250-300 ft depending on the lengths. Longer planks will produce more waste in the bow area.
My experience says 1/8” thick will be a challenge to mill, anything less than 3/16” will starting tearing out through the planner. I used 3/16” X 8” wide and 13 ft long. 3/16” will argue about the bending and twisting at the bow but it’s doable.
Hope these numbers are helpful,
Matt B

If I had to do it again I'd consider buying a decent drum sander to avoid all the planner tear outs. Although, I've read that if you lightly wet the material and take thin passes on the planner it will help.

I had 1/8" made up but it was planed and sanded to finished thickness. 1/8" is more flexible, but also you can sand through it easier.

Ben… I would consider going with wider planks, say 10" wide by as long as possible. That will allow you to end up with planking at least 5" wide on the hull. More waste, but will look more like the original Mahogany planked speed boats. I had mine milled to 1/8" thick for my Gentry and I bought it all from Stark Lumber and Millwork (Marianne) in Bangor, PA. 610-759-1753. When they hand it to you, it won't have any flaws. Great folks to work with. I wouldn't order more than you need for the sides and transom as you will most likely be using 3/8" thick for your deck. I think they will ship it to you, but not sure of the cost. It may be worth a trip to Bangor to pick it up. Happy to see you back at it... Neel

Just went to Exotic Lumber in Annapolis. They have been my source for the oak frames and the okume. However, they were unwilling to kill mahogany in anything less than 1/2 inch or so.

Going to call neels guy in PA now.

Ben: I have gotten material from Stark Lumber. Great people to work with. I plan to get my decking mahogany from them. It is a bit of a drive, but I want mahogany and my supplier near me only has sapele.

Certainly wood veneer supplied my veneer in 1/6 thickness which was helpful. More leeway than 1/8th of an inch.

My lumber yard in Charleston milled all the sapele I needed for my hull decking, in 8 or 9 inch widths. I believe the total cost was $300 (wood and shop fee). That is, they performed the resaw work. I asked them to select boards that would give me a good color match and was very pleased with the result.

The resulting planks were about 5/32 - 3/16 but many had blade marks from the band saw. I removed the marks by planning them all down to 1/8, using my Dewalt planer. I used a melamine coated piece of 3/4 plywood to raise the planer deck. I did not have to wet the wood, as some suggested and had only one, minor, bit of tear out.

My band saw would not handle the resaw work (only 6" throat) and I was VERY pleased with the work and the price. So... can you buy mahogany and find someone who will mill it for you?

The wider boards are needed for spiling...as the bow curve will reduce the widest board to ~4 inches. Jimbob gave me some great advice on a simple method to measure and calculate the spiles. I also used the fence on my palm router to cut the curve on each subsequent board, temporarily slid under previous board. Details are in my Key Largo Charleston build...

1. Got some wood from neel Thompson, thank you sir! It was nice to meet you

2. Got a laser line level. Amazing tool for planing planking and drawing the waterline on. Seen in pic is the tool (comes w magnetic attachment which works great on my garage support pole) (tool is in yellow circle). And the red line it puts perfectly level on the boat. Measured the location of the waterline at transom from plans and brought forward via the laser level to bow. This will allow me to see what areas need mahogany vs ok to do w okume towards the bottom bow area. Will also be used to plan the planking with the “level” feature turned off so its only projecting a laser in what ever angle I need.
