In early September, we were asked to make three, big (60 cm x 93 cm) shelves for the ministry office. Knowing that I would be away travelling for the first half of October, I responded that we could - but not until the end of October.
A couple of the older boys helped rip up two blocks of fir (called
pino cipress here) into 4 cm thick slabs during September so that it could dry by the time I returned from my trip. Unfortunately, I don't have any pictures of this process.
After my return, we planed the slabs down to 3 cm thickness and trimmed them up to make them into finished lumber. After that, we formed the tongue and groove pattern on the edges using multiple passes with a rabbit bit and then a slot cutter on our provisional router table.

Our provisional router table, which consists of a piece of 1/2" particle board clamped to an set of table legs from an old table saw, supporting a 2.2 Hp Milwaukee router. It works, but leaves a lot to be desired, so in December I began making a REAL router table - which you can read about in a later post... |
We then glued up the shelves and after they dried, the boys began sanding them flat.

The shelves now glued and clamped together. |
We then trimmed the shelves to finished size and beveled the upper surface of the front side of each shelf using the hand-held router. Sorry, no pictures of this step....

The boys spent a good bit of two afternoons sanding, it was surprising how long it took to sand both sides of the three shelves, going down t through the various grit sizes to 120 grit with the belt sander and then to 320 grit with an orbital sander.

Finally, it was time to begin applying finish. We applied three coats of sanding sealer and then two coats of tinted lacquer to make a nice, smooth finish. Of course, we sanded the surfaces again lightly between coats.

We completed the shelves on November 3rd, a few days later than promised, but they turned out very nice.

Nancy Centeno, the IMC Director in Colombia, liked the shelves so much that she has asked us to make three more for her office...
