On Track

Fiber-glassing the bottom is going well. The plan to have it done by today went by the wayside when Saturday's commitments made their presence known: an afternoon memorial service for a WWII veteran and an evening house concert in Grand Rapids. Why - or how - is it that known, scheduled events are completely forgotten when working on the boat?

Here's a couple of photos of the most recent piece of fiber-glassing… A before and an after:

Fiber-glassing doesn't look like much in a couple a snapshots but these photos document progress. The last bit of glassing involves a triangular piece on the bottom and separate pieces for the front end of the first plank. I'll cut those three pieces tomorrow (when today's epoxy isn't tacky) and epoxy them in place after fitting.

Fairing the hull will take a few days, I am sure. QuikFair's cure time allows multiple applications per day so I should be able to work nicely around a couple of appointments over the next few days.

While I lost a day of boat work to social activities - which were completely worthwhile - my time-line for getting the hull prepped and painted before the end of October is still good. Wiggle room was built in to the time-line.

Out of Chaos...

Tuesday's chaos gave way to a certain measure of progress over the last three days.

Half the bottom has been covered with fiber glass and epoxy. The rest of the bottom should be fiber glassed tomorrow - Sunday at the latest.

The second and third planks on each side have been epoxy-coated. Fairing of those will begin tomorrow. I am using System 3's Quik-Fair. I liked the small test sample I mixed and used on Wednesday so I am looking forward to fairing the hull.

The sheer strakes/planks need the trim strips fitted and installed before being epoxied, faired and prepped for paint. I had thought of using mahogany for the trim, but I am reconsidering that idea. Given the lengths, twists, bends and curves involved, my thought now is to laminate thinner, shorter lengths of Douglas fir (which I happen to have on hand) in place. I have to give that plan a bit more thought…

In addition to the physical progress of the last few days, I've got a workable timeline for getting the hull painted and turned right side up before it gets too cold to paint.

So, things are looking up!

Strange Day

It was - I was - unfocused. And that is being kind and generous. Bouncing from one thing to another but getting nothing accomplished - that was my day.

Early to bed, early to rise… and all that hopefully means I will be more focused tomorrow. Maybe... I will get something DONE!

Fitting the Skeg

Or… How to remove a bunch of material without making a lot of progress…

The skeg was rough cut to size and loosely fit to the hull a few weeks ago. There were a few high and low spots creating small (4 - 5mm) gaps in several places where the skeg didn't quite match the hull. Today, I decided to trim it to a nice tight fit…

I marked a line on each side of the skeg by sliding a carpenter's pencil along the bottom; there were some very minor differences. Using the grinder (with a flap-wheel sander) and the palm sander with 60 grit paper), I sanded to the lines and checked that the skeg was square. Put it back on the boat… There were a few - different - high and low spots putting the small gaps in different places.

Repeat the process - except to mark the low spots not the entire skeg. Similar results.

Repeat the process: same results although the gaps were getting smaller…

The whole process reminded me of efforts to even the legs of a chair to eliminate a wobble...

I stopped when there were only a few gaps and those gaps were no more than 2mm. I could have kept going to the point of sanding away much of the skeg but decided thickened epoxy, screws and glass-topped fillets will have to do.

Optical Illusion?

While tidying up the bottom edges of the planks, I spent some time trying to get a nice, sharp, crisp edge - because that's how I thought the edges should be… and struggled with the bumps and hollows. Then, while checking the Building Instructions for something else, I (re)read this:

Tidy up the underneath edges of the planking. This is critical to the boat's looks. Use a wooden batten around to indicate the bumps and hollows. Plane the edges fair with a rebate plane (or small block plane), fill the undersides and round them as shown on sheet 6. (emphasis added)

The wooden batten certainly helps but what surprised me most was that rounding over the edge made the the bumps and hollows visually disappear. This photo sequence illustrates this effect:

The raw edge:

Planed & Rough Sanded:

Rounded over:

Of course, there is more work to be done on the edges, but the modest statement, "This is critical to the boat's looks." is clearly an understatement. And rounding over the edge is a brilliant optical illusion - at least for me.

Boat Hook Project

While waiting for epoxy to cure I have time to dream up new projects…

A couple of weeks ago I sat in Atlanta browsing DuckWorks' site and came across a bronze boat hook head fitting. That lead me to pricing boat hooks at Shaw & Tenney. THAT sent me back to DuckWorks… I decided to make my own and ordered a boat hook head fitting.

Here's a peek at the project:

The practice piece was tapered using a grinder with a flap-wheel, a belt sander and a palm sander. It took a bit of time but the taper is a good fit. I am hoping to do as well with the real handle.

The varnished piece is a cut-off from the 8' 1¼" square blank I glued up using old maple flooring. I planned to take the handle round, but I like the octagonal shape - it looks and feels good - so I decided to leave it 8-sided. The two coats of varnish on the test piece tell me I'm going to like the looks of the finished product.

Work on the hull continues albeit not as quickly as I hoped for... sanding, epoxy, fiber glass, fairing, sanding... all with the intent of getting the hull faired, primed and painted by November.

Plank Gauge

I may be a slow study…

Eyeballing the planks to get them symmetric from side to side wasn't working too well for me. I can step back from one side to get a decent look but the other side is close in to a wall, limiting the visual perspective. And, even though I did some trimming and sanding, I wasn't very happy with the 'other' side. And, even I could see the planks were not symmetric (never mind that I could have cut the planks in pairs… ).

A friend of mine is fond of saying, "If you can't put a number to it, it's just voodoo." And that's what I felt I was doing - somehow, the planks would magically match up. So, how to put a number on them?

This is where I may be slower than some… It took me a while to figure out I could measure points on the planks on one side of the boat and transfer those points (measurements) to the other side, connect the dots and cut to that line.

So, a nice long straight edge, a carpenter's square and a ruler resulted in an impromptu plank gauge.

I marked off 12 stations along the centerline of the boat, drew perpendicular lines to the chines, placed the straight edge across at each station and measured to the 'top' of the plank, recorded the measurements and transferred to the other side. Masking tape 'connected the dots' and the multi-tool trimmed away the excess material. An assortment of sanders and rasps faired and smoothed the edges of the planks. Gardens is looking much better to me than she did earlier in the week.
