I'm what you could call a classic "over-thinker". For just about my entire life, I've pretty much always been one to spend a good while pondering over the possible outcomes of an action (often to excruciating lengths) rather than just diving in. Financial purchases are a big one (i.e. taking 5 years to talk myself into buying this boat!), and sometimes unfamiliar projects can be as well.
Not to say that this is necessarily a bad thing. I'd like to believe that my "over-thinking" translates into "over-preparedness" in the end! However, most of the time when I finally just jump into whatever I've been stressing over, it's not nearly as bad as my mind made it out to be.
Yesterday's project was a perfect example.
When I bought my boat, a number of the blocks were looking a little old. A number of them were showing signs of wearing out, and I wasn't too sure how long they would last before they'd have to be replaced. Here's an example of what I mean.

| A "tired" turning block |
This is a turning block for one of my genoa sheets. Essentially the sheet (or rope you use to control the sail) comes back from the sail at the front of the boat and "turns" 180 degress through this block to go to the winch. It helps to give your mechanical advantage when your pulling in the sheet, or powering up the sail.
As you can see in the picture, this block has seen many a long day. The pulley wheel was worn to bits and the wooden spacer that lifts the block off the deck was all but decomposed. Not ideal.
In fact, after a solid day of sailing in 18 knot winds a few weeks back, the pulley wheel was actually even more shredded than it is in that picture. Long story short, it needed to be replaced.
So how do you replace a turning block? Well, it's 3 "easy" steps.
Step #1 - Find a Replacement
Seems simple enough, right? Well not entirely.
My first challenge was to figure out what you even call the type of block I was looking for! As this blog has already demonstrated, there are approximately 1,295,385 different technical terms related to sailboats, so it took a bit of creative Googling to find what I was looking for.
Turns out, it's called a "cheek block". The more you know!
Googling also told me that
Merriman Brothers, the est. 1898, Boston-based marine hardware company that made my old block, had closed its factory in 1995. So a direct replacement wasn't going to happen. Closest thing I could find was this Barton block.

Step #2 - Make a new wooden spacer
I live in an apartment in Vancouver, so needless to say, I don't have a wood shop. Thankfully though, my friend Rhys does. Last week he was kind enough to cut me some pieces of wood he had lying around. Bit of measuring and drill work on Saturday morning and I had the makings of some deck spacers (and thankfully no holes in my galley table!)
From there, I went at them with sandpaper. I'd forgotten how satisfying it is to work with wood. When I started, the spacers just looked like two pieces of scrap wood (exactly what they were). But after 25 minutes of sanding, they were starting to show some promise.
Four or five coats of varnish later and they actually looked pretty awesome!
Step #3 - Bolt the block onto the boat
Well, once again, not quite as easy as it sounds. As it turns out, Barton decided to alter the bolt pattern of their block ever so slightly from what Merriman had gone with. Two out of four holes matched up fine, but not the others. So this meant I had to fill the old holes with epoxy and then drill new holes.
Terrifying...
Filling the holes was pretty straight forward. Take some duct tape, add lots of marine epoxy and I'd made a proper mess, but filled the holes as well.

| Filling the old holes with epoxy |
All weekend I stressed about drilling the new holes. I researched drill techniques, drill bits, etc. for most of the evening on Sunday. The idea of putting holes in my boat, regardless of how tiny they were, had me worried.
Monday night, the epoxy was dry and it was time to do it. I was nervous... My buddy Nish came by to help. He also brought beer, which helped with the nerves. After sanding the excess epoxy smooth and consuming a few of the beers, I kicked my over-thinking to curb and drilled out the four holes without issue. Classic over-thinking...

| Nish with some contortionist moves to bolt the new blocks into place |
I added some butyl tape to the bolts before putting the blocks on and countersunk the bolt holes a bit. This helps to water-seal the holes. All the bolts actually lined up and the blocks plopped into place perfectly, much to my surprise!

| Pretty varnish and some butyl tape |
The finished product look pretty damn slick if you ask me! Nish and I enjoyed a success beer, and I couldn't stop admiring our work!

| All done! |
So it turns out drilling holes in your boat and mounting new deck hardware is actually pretty straight forward!
Take that brain.
The learning continues...
