To the extent I can in my small shop, I like to take a step back from time to time and admire my progress. Generally I am well pleased, but recently something a bit out of line caught my eye.
I think this had been hiding until the contrasting paint showed up the unevenness in the trim piece I had installed at the top of the bow transom last September (see this post: <rubrails>). My intent was to have the bottom of the trim match the curve of the deck, but looks like that didn't work out:
I thought about this for a while wondering how I could most easily correct the problem. My planes would not work on this concave surface. A curved sanding block beveled to match the edge angle could work, but that seemed like a lot of work and not guaranteed of success.
I finally hit on the idea of making a custom router base to which I could attach a fence curved to fit the deck, and a leg to hold the bit at the correct angle.
Here's a shot where you can see how this fits against the bow of the boat. The bit is 1/2 inch diameter, and set to the correct depth will give me a nice radius at the bottom - I won't even need to re-fillet this joint.
Here's a first pass on one side, showing the amount of material that needed to be removed.
And here's the final result before painting. I feel good about getting this evened up. Clicking on any of these photos should show you a larger view.
