Thos look nice and clean. I'm building my dash right now and have no idea where I'm going to put the switches and gauges. I'm not even positive which gauges I want. Good for you planning this far ahead.

Thank you, Matt!

From the beginning of this project, the look of the dash was very important to me. I toyed around with different dash shapes and gauge layouts, and originally I wanted to mimic the look of the Riva Florida or Junior dashboard. Like a lot of people, I'm really fascinated by the classic Riva boats... but in the end, I felt that trying to mimick that look would just come off as cheesy.

The first time I saw the dashboard on Bob Brandenstein's Malahini, I knew right away I wanted to do some type of inlay.

Seeing Joshua Burks' dash in his videos was also very inspiring as far as making an inlay dash.

I also very much liked the layout Roberta did on Oliver IV. I know its a small detail, but I always liked the rocker switches she put just to the right of the helm:

Image

So, yes, I did spend a lot of time planning it out & obsessing over it. In the end, I kind of combined the best of everything (or at least I tried to). The elongated oval shape for the inlay is my own little "tip of the hat" to the Riva Junior. I'm planning to use only one rocker switch to Roberta's two.

Due to the way I'm building frame #4, (with the angled dash beam being integral to the frame), I felt it would be easier to go ahead and make all these cutouts now, rather than when it's part of the hull.

Maybe you should wrap that dash in plastic or even cardboard until after the flip Then you won't get glue on it or drop a chisel on it or something.

That's a good find Mike. Looks like the Lake Shore Castings ones already finished. I always thought as comparatively inexpensive as the lake shore castings brackets were that someone could make some cash by buying the lake shore castings brackets, polishing them and reselling them.

After cleaning most of the epoxy away, I could get a better look at the fitting in the keel lamination. It's definitely less-than-perfect. I'll be grafting on some more wood in a few places, and there are definitely things I wish I'd done differently. However, I believe it's still solid enough to work.

In some areas, the fitting was pretty decent.

I learned to never assume the lumberyard edge is straight. This narrow spot is at the starboard aft. I'll be grafting some more wood to fill this in.

This side, near the butt joint, needs more epoxy fill in the seam, as well as a shim grafted onto the side.

Tonight I started grafting shims onto my laminated keel.

I have been giving some thought to simply re-building the keel, due to the less-than-perfect fitting. I had re-sawed the material with a table saw. I had to flip the piece in order to make it work. While effective, the saw kerf left a lot of surface irregularities. I did not get these all planed flat. At the time, I feared the wood was getting too thin, but this turned out to be untrue. Chalk one up to experience.

Most of the surface-to-surface fitting in the laminated section is... decent. The largest gaps do not span the full width of the keel (maybe 1/3), and at most are about 3/32. These gaps are filled with a LOT of epoxy that is thickened with mahogany wood dust, so it's not like there is a void there. The currently laminated section will be at the back of the boat, where the hull is flat. I don't know what kind of stresses will be involved there. Part of me thinks the lamination is sufficiently strong as-is. I could also add a stiffening piece after the flip in order to reinforce it more. The other part of me feels that if I do want to rebuild the thing, now is the time to do so.

My inner pragmatist doesn't want to rebuild it unnecessarily, if it is sufficiently strong as-is. I'm really on the fence. Any opinions?

Probably okay. But it it keeps you up at night you might want to do something about it. I'd ride in it with that keel. :wink:

Its hard to tell without seeing what exactly it looks like. I'm pretty certain I'd use it. The wood seems solid, are you just concerned about the epoxy holding from the voids? When you put on the bottom planking maybe put screws in the keel that are the same length as the thickness of the keel so you have mechanical fastening as well. Like you said, you could cap the keel after the flip between the frames, I dont think that would hurt anything either. I think this is one of those times when we are our own worst enemies because we know of every fault. Once its flipped and a sole is installed youll never see it so pretty doesnt matter here.
I'm thinking the aft part of the keel might see its most load from the motor weight while trailering, but if the bunks extend slightly past the transom maybe that load is actually spread to the transom frame? I would think the section just under the front seats see's the most load while on the water? Just guessing, I'm no engineer. I'm with hoodman, I'd ride in it... and plow through Butch's wake without worry :D

Spoken like a true pilot!

As you mentioned, I guess my main concern is the thickened epoxy providing enough strength in the voids. The more I look at it, the more I think you're right about simply being my own worst critic. Since it's in the flat, aft part of the hull (just behind Frame #2), and with a stiffening piece added, as well as the longer screws you mentioned for the planking.... I think it'll be fine.

I keep thinking back to GDCarpenter's Zip, which he built using epoxy only, and no screws. That's a huge testament to the strength of marine epoxy. Even though the fitting on my keel is nowhere close to being as good as his, I do believe it is solidly functional. Like you said, it doesn't have to be pretty right there.

I'll just learn from the experience and better-prepare the rest (forward 1/2) of the keel for a better fit when the time comes.

I'm in the process of encapsulating Frame #4, including the cherry inlay for the gauges. The grain in the dash beam shows a lot more contrast than I expected it to when coated with epoxy. The cherry also got a bit darker and "browner" than I expected.

These photos show the surfaces that will be hidden. While the contrast between the mahogany and the cherry isn't too bad, I'd like it to be more. I also wish this mahogany piece didn't have so much light-dark contrast in the grain.

I'm considering staining the dashboard face of the mahogany to darken it some before I encapsulate it... also in hopes that the stain will darken the lighter part of the grain sufficiently enough that the whole piece is less "contrasty." Then, hopefully, the whole thing would be dark enough to offset the natural-finished cherry a little better.

Any thoughts?
