Trimming Frame Members

Now that I have the lumber for the frame members cut to rough shape with a corresponding router template for each part, it’s time to trim them to final shape. I setup the router in its table with a template bit beforehand. This is also my first time using a template bit.

I used screws to hold the 1/4” MDF templates to the boards so they wouldn’t move. I tried to locate the screws so the holes will be hidden under the gussets. 


I trimmed each board on the band saw so it was slightly larger than the template (1/16” or so on each side). I then went to the router table and used the push handle to move the wood clockwise across the router bit. It took a little while to get the hang of which side of the wood to put the template on so the cut would follow the grain to prevent chipping, but I eventually figured it out. 

I really liked this method of making parts. They came out very smooth (barely need sanding) and exactly to shape.

After trimming the parts, I was very happy with how closely they matched the plans. 


I did some more tracing to make a full size pattern of each of the five frames. The plans only have full size patterns of the right (starboard) half of each frame. I had to mirror the patterns across the center line to trace a pattern of the left (port) half of each frame. I was very careful to line up the halves but am still a little worried if I got it close enough. 

With the parts laid out on the patterns, I really feel like I’m starting to make progress.  I almost have a boat kit ready to start assembling!

Next step is to assemble the frames. All joints will have plywood gussets that will be epoxied and nailed in place.  But first, I have to wait for the plywood and silicon bronze fasteners to come in. 

I couldn’t find any 1/4” marine plywood locally, but after some searching found some in Canada. The best part is they have a warehouse an hour away so no delivery charge (which is very expensive for 4’x8’ plywood sheets). I ordered: 
  • 4 sheets of 1/4” okoume for the hull
  • 1 sheet of 1/4” okoume  for the centerboard case and gussets
  • 2 sheets of 1/4” Sapele for the deck. 
I was very happy I could find it within driving distance.

Welcome

Welcome! This is the story of my Glen-L 15 sailboat build.  This is a 15’ long wooden sailboat I am building at home from a set of plans I ordered from Glen-L. It will be my first sailboat so I’m looking forward to learning to sail on it. This is what I hope it will look like when I am finished: This is my current progress: I spent a few weeks looking at several sailboat plans and chose the Glen-L15 because I wanted a traditional Bermuda rig (the classic triangle sail on either side of the mast).  Glen-L also had a long history and great reputation, an active online community, and sold hardware and rigging kits for this boat.  Construction will be plywood sheathing on a solid wood frame.  The links below are in chronological order, as they are best read The Plans My Shop Patterns and Templates 3/4” Plywood Parts Rough Cutting Wooden Frame Members Trimming Frame Members Waiting for the plywood Cutting the gussets Building the frames (finally!)

The Plans

Image
The plans were delivered quickly and included Five sheets of detailed drawings Two sheets of full size patterns for all parts A 15 page instruction book Glen-L also published a Building Plywood Boats book that I bought.  I hung up the plans to study them before I started building with a goal of being able to picture the entire build process in my head. It took a full day of reading (and re-reading) the plans to get mostly there.  The plans have a very old fashioned feel to them, which is no surprise given their age. In fact the plans had an almost familiar feel to me. Then I remembered we had a set of Popular Mechanics books when I was a kid and one of them had an article on how to build a boat out of plywood at home. I used to pore over the pictures and instructions in that article and think how fun it would be to actually build something like that. I am pretty sure now that those were Glen-L plans I was looking at way back then, albeit for a different boat (a one-man power boat to th

Building the spars

Image
The spars are the wooden “poles” that hold up the sails and consist of two pieces: the mast (the tall upright post) and the boom (the horizontal member that attaches to the mast and swings to control the angle of the main sail).    The mast is made from a 22’ long piece of 3” x 4” Sitka spruce. It is tear drop shaped in cross section and tapered getting narrower at the top, so I will have to shape it out of a rectangular board. Sitka spruce was hard to find.  The only place I could find it was a boat building store near Toronto, Noah’s Marine, which is about a three hour drive and in a different country.  Luckily I had to drive to Toronto anyway so I stopped on the way. Even then, I couldn’t find a piece big enough to make the mast out of one piece (which I expected), so I had to make it out of several pieces. I bought 6 boards each about 1” thick by 4” wide by 12’ long, which I spliced in pairs to make three 22’ long lengths that I’ll stack and glue to make a single 3” x 4” x 22’ long
