Cutting the Transom Cheeks on the Palm Beach 22

Palm Beach 22 transom cheek

It seems like forever since I talked about working on the Palm Beach 22 in this space.  Intervening boat repairs do have a way of taking up time here at the boatworks!  Anyway, when we left off I was talking about the plan for framing the transom.  I had made up 2 blanks with the curve of the transom cheeks.  You can read about it here.

Transom cheek blank
I checked the curve of the blanks to the lofting board. If you look closely you can see the line for station 10 hugging the piece, just inside the line for station 9.

You can see the blank laminated to the curve here.  Now it’s time to cut the compound curve out of this blank.  Remember this piece not only curves inboard, it also curves aft when you look at it from the side.  Take a look at Zimmer’s drawing again.  It’s at the top of this post.

Framing the Transom of the Palm Beach 22

Transom framing for Palm Beach 22

We’ve got all the frames built and set up.  But we’ve still got to frame the transom of the Palm Beach 22.  We’ll build the framework and add it to our setup so we can begin planking.  The picture above is a rendering of what our framework should look like.  Note that I’ve pointed out a particular piece I call the transom “cheek”.  You can see the transom curves inward at the top (called “Tumblehome”).  This is part of the signature look of a mahogany runabout.

Just When You Think You Know What You’re Doing…

Awlwood Red stain bleed results in dark bumps that must be sanded away.

You find out there’s more to know.

Well, that’s often the case here at Ashley River Boatworks, anyway.  In my last post, I talked about making a test strip to decide what stain and finish options to use in the Palm Beach 22 runabout we’re building.  I wanted to test some conventional oil based stains next to a new staining system by Awlgrip that I used on a previous project–a restoration of a 1949 Chris Craft runabout.

Picking a Color for the Boat

Making a Stain Test Strip

It’s not too early to start thinking about the finishing program for this boat.  I know, it seems ridiculous to be thinking about this at such an early stage, but I want to test several different options for varnishes and urethane clear coats for durability.  Considering the effort that goes into finishing, it’s worth gathering a little empirical data to help make the decision.

Setting up the Palm Beach 22

Laying a batten across the frames shows high and low spots

Once you have the frames made, you have to set them up in the right position.  Oddly enough, this process is called “Setting up”.  (See, there are actually some terms in boatbuilding that are self-explanatory!)  The primary thing is to get the frames secured exactly the correct distance from each other and at the proper level.  You do this by using guidelines that you’ve transferred from your patterns and lofting to the frames themselves.  For instance, you draw the center line on each frame, and align it under a string line on your strongback.  Also, you can attach a cross spall to each frame at, say, the +24″ waterline.  Then line these up as you erect the frames.

Solution to a Vexing Problem

Lining up the frames for the Palm Beach 22

As you can see in the above picture, we’re starting to compile a nice set of frames for the Palm Beach 22.  If you’ve forgotten what this boat is supposed to look like, you can check out the plans here.  At any rate, you can see the frames have notches in them for battens that run the length of the hull.  And as luck would have it, one of these notches is over the top of the 1-1/8″ wide x 6-1/2″ deep stringer.  The frames are to be held fast to the stringers with 1/4″ carriage bolts.  That means drilling and counter boring holes through the frames and the stringers.  That presents us with two problems.  The first is how to drill that long hole through both the frame and stringer.  That’s a tough one to just eye-ball without accidentally coming out the side of the stringer.  How would you do it?

Patterns for the Frames

CNC cut patterns for the Palm Beach 22 designed by Nelson Zimmer

I was able to get full size plans for the frames of this design from a fellow in New Zealand.  Using his CAD files, I was able to use a CNC (computer numerical control) router to cut out patterns for me to use in cutting out the frames.  Sounds like a nifty process, doesn’t it?  Well nothing is ever as easy as it seems.

Wood Moves!–How to Cope

Cutting a board sometimes releases stress that makes it warp.

One of the problems any woodworker faces is the fact that wood can move on you.  In the photo above, you can see how a “practice stringer” I cut curved like the dickens!  I suspected it might do this, which is why I cut out the practice piece.  You see, cutting a board will often release tension in the wood.  That’s why a board can close up and pinch your saw sometimes causing it to buck.

The Strongback–A Platform to Build on

A good strongback that can be rolled around the shop is a great foundation for your boat project.

You need something to hold the frames in perfect alignment as you assemble the parts of your boat–something strong that will hold the shape you want over the period you’re building the boat.  It has to be rigid and easy to attach pieces to.  The answer is a Strongback.  And I want to be able to move the boat around the shop if I need to as well.  At some point, we’ll have to flip this hull over to work on the inside.  It will be nice to be able roll the strongback around the shop to get the gantry cranes over the hull when that time comes.
