I Install A Knob (Really)

Continued from last time...

The second demonstration I was anxious to watch was John Brook's Routers. Specifically, using routers for boat building.

Having recently purchased my first router, I am hooked on the usefulness of the tool. As John pointed out in his presentation, while most power tools are direct replacements for traditional hand tools, routers do many things that no hand tool ever did. It's one of those rare things: a new tool.

Routers are so flexible, its hard to imagine half the things they can do, so getting tips from experienced builders can really give you a boost along the learning curve.

Speaking of curves, John's first demonstration was how you can use a router to make complicated pieces using a pattern.

Using a pattern 
In the photo above, the pattern is attached to the bottom of the stock. The router bit is a trim bit with the bearing on the top (the router is upside down in the photo above.)

The pattern rides on the bearing, and the wood is cut away by the bit. To make a symmetrical piece, like the one above, you use a half-pattern, flipping it over to cut the other side.

The trick here is to make the cut in sections, according to how the grain runs, moving the piece from left to right or right to left, to avoid making a climb cut, which besides being somewhat dangerous, could break a piece off if the bit catches the grain the wrong way.

I noticed that this expert woodworker and boatbuilder made his own router table, and it was pretty much as rough and ready as mine! Even his fence was similar. His was twice as big, though, and had two holes cut for two routers. Saves changing bits when he's doing production work. Great idea. Also note the shop-built guard. More tool making!

Scarf cutting jig
Another interesting tool was John's plywood scarf cutting 'jig'. To make the scarf, the two planks are laid on top of each other. Then two battens are clamped to the work and table. The spacing between the two battens determines the length of the scarf. The router is mounted on a wide plastic base which rides on the two battens (and fits into the router table). With a straight bit installed, it's a quick job to cut the two scarfs at exactly the right angle.

It took me a minute to get my head around the idea of using the bottom of a straight bit to do the cutting, but if you think about it, you can see how it works.

When I think how much time I spent scarfing two bits of plywood together for Cabin Boy's sheer strake, I could cry.

Another enormous time saver is John's 'Gain-o-matic'. This simple jig is used to cut the gains in the kind of glued lapstrake boats John builds. A gain is the kind of ramping cut that allows lapstrake plank ends to blend together.

Gain-o-matic
 The plank is inserted into the jig. The router -- again with wide base -- rides on the rails on either side of the jig. These slant, so as the router with straight bit goes down the ramp, it cuts the angled gains precisely -- something that is not so easy to do with a hand plane, as I can tell you.

The theme of all the demonstrations was the same: simple, often shop-built tools can not only make a job easier, but can help you do the job better. Good tips for unhandy builders like myself.

Speaking of boats, there were two more boats that caught my eye at the show. One was a Oughtred Caledonia Yawl, built by Geoff Kerr of 2 Daughters Boatworks. These are very popular boats, and for good reasons. Every time I see one in person, I'm impressed with how well thought out they are. As much as I love my Blue Moon, I can definitely see the advantages of having an 18-foot boat that you can pull out of the water and store in the driveway over the winter.

The other boat that caught my eye was a strip-planked kayak build by Nick Schade. There's a lot to be said for strip planking, but I have never been a fan of bright-finished strippers. They always look too busy to me.

But this year Nick had a beauty where he took the time to select and match the strips so that they blended together well enough that from several feet away, you could hardly notice the strips. In fact, it looked planked, rather than stripped.

Strip planks that don't looked striped
These are all strips of cedar, but cedar varies greatly in color. You can see how Nick has selected the colors to create a sheer strake and bottom, with a couple of trim stripes for accent. Very well done.

Another boat I'd like to build sometime. Where will I find the time, though?

Finally, I made two purchases at the show: a decent riggers knife that Hamilton Marine had on sale for an irresistible price:

My new riggers knife
This is something I've needed for a long time, but good knives are so expensive I've been making due with an old one that didn't have a spike. Eric was never without a sharp riggers knife, and seemed slightly disgusted that I didn't have one in my pocket, not once, but several times!!! I won't be embarrassed the next time someone asks, "do you have a knife?" Seems like a really nice tool.

At another booth, two young men were showing off their blacksmith skills. They had a wide variety of caulking irons and other heavy duty tools that I probably will never need, and a small variety of shop-made cabinetry hardware, like hinges and knobs.

The little drawer that I made for my new galley still didn't have a knob, because I've been waiting to find the 'right' one. The ones you can find at Home Depot and hardware stores looked a bit too polished for my little gallery. I just couldn't warm  up to any of them. But I was instantly taken by the wrought iron knobs made by these two gents. They didn't have any stock, but they let me buy one of the demonstrator knobs.

Hand made iron knob
It looks positively medieval, with the hammer marks showing in the iron, but I love it. I think it looks just right on my rather crude hand-made drawer.

Love it.
I would love to give these two young guys a plug, but I've lost their business card. If you were at the show and visited the blacksmith booth across from the Wood Mizer booth, and have any of their contact information, please leave it in the comments below, or send me an email. Thanks!

So, all in all, a very productive and worth-while show.

And, I'm back to building, at least for a little while...

  1. Just mind that you aren't thrown in to that knob when in a seaway John, it looks like it could pierce you and then get a hold!

  2. Gosh, you are right! It looks like the tip of a spear. I never thought about that.

    Luckily, this drawer is really tucked away, under the side deck. No way you could ever be thrown against it.

    I just realized I haven't posted a picture of the installed dish rack--or even taken a picture of it. I'll do that next time.

    But definitely something to think about when selecting a knob.
