A Crate Experience

Our second homework task for this class was to create a crate. This assignment was slightly daunting at first. I’ve used woodworking tools before, but it never seemed to come out right. There was always a wrong angle or a hole or a lip on the product that I couldn’t get rid of. I didn’t expect my crate to be perfect either, but I was hopeful that it would be better in function and looks than other things I’ve made before.

We started off by designing the crate. I like planning things out, so I drew the crate with dimensions and some ideas for what it would look like. It was also helpful to have an idea of what we actually had to do in terms of steps to take. We had three stages of this process: preparing our materials, constructing the crate, and post processing of the crate.

Once we had an idea of what we were going to do, we started preparing our crate materials. We opted to not have our wood pre-cut, so we started off by marking the lengths of pieces we would need and using the miter saw to cut them.

Once we had our cut pieces of wood, we sanded each one with 60 grit sandpaper and a 120 grit electric sander so that we could safely work with them and there were no super rough edges in our final product. We knew we would sand the box at the end, but we wanted to sand each piece at the start in case there were edges we couldn’t reach in the final product. We also used the belt and disc sander for a few that needed to be slightly shorter.

After that, we routed the pieces based on our plan. We didn’t want to route all edges, but we wanted the sides of the crate to have a few round edges. We opted to use the table router as it was easier and we only needed to route straight edges. The last thing we did to prepare our wood pieces was cut out handles for our crate. We chose two pieces that would be the handles, and used a jigsaw and the circular sanding tool in the woodshop to cut it out and smooth it down. We chose to cut out heart shaped handles as it made our crate more aesthetic. Finally, our wood was ready to be put together.

We worked both at the inside table and on the loading dock to construct our crate. Our first step in constructing the crate was making three frame shapes out of 1×4 pieces that would become the sides of our crate. For these, we used the corner clamps to keep the wood in place, and screwed it together with wood screws. We used two different drill bits to make pilot holes and then countersunk holes for the screws. We had some issues with these bits where we had wood chipping off of the sides of our holes, which left some holes in our final crate. This was frustrating, but we didn’t have a way to repair the wood, so we had to leave them be. We repeated this process for all four corners of each frame, and ended up with three frames.

After we made our three frames, we put the floor of the crate in and screwed that in as well. We fit the three pieces into the bottom frame and screwed them in from the sides. This was also frustrating to do as the bottom frame and floor pieces didn’t line up to make a smooth bottom for our crate. The three floor pieces were fairly even, but the bottom frame was slightly above them. We decided to try to tackle this issue during the final stages of making our crate rather than redo the floor. After that, we put our four 2×2 pieces in the crate and attached them to the bottom. We started stacking the frame pieces and screwing each one into the four vertical 2x2s, using the same method as before with a pilot hole and countersunk hole.

Once we screwed all three frames onto the base structure, our crate construction was done. I was happy with our final crate structure. It is quite sturdy and easy to carry or use to hold items.

Now that our crate was reconstructed, we moved onto some post processing techniques. First, we sanded the whole crate. We used an electric sander with 60 and 120 grit for the sides of the crate, and used sandpaper for the inside and small edges the electric sander couldn’t get to. This was the stage where we put in a lot of work to get rid of the small imperfections that came with constructing the crate. We sanded off any wood chips from the screws and did our best to smooth down uneven edges. This was also useful to prep the wood for any staining or spray paint we wanted to do to our crate.

Once our crate was fully sanded and cleaned, we decided to spray paint it. We wanted to try some different colors, so we decided to try a gradient of blue and purple. We picked two blues and a purple that were paint and primers. At this point, we moved down to behind the loading dock and found some cardboard to use as a base. To try to get a gradient effect, we made the base and half of the first frame of the crate light blue, made half of the first frame and half of the second frame dark blue, and made the entire top half of the crate purple. We let the colors overlap slightly, but we didn’t entirely try to paint over the different colors as we didn’t want a lot of drippy overlapped paint.

We also did our best to match this on the inside, though it was hard to do with limited space. We also had some areas where the paint dripped due to us spraying too close. The last issue we had was having some splotches not fully get covered in paint. These issues were hard to overcome with limited spray paint experience, but I am still happy with how the crate came out in terms of color.

I think it definitely made the project more exciting and was a good way to get experience post processing wood. I think I’d still like more experience in this area, or some tips on how to make spray painted things look better. Once we finished painting, we left the crate out to dry and cleaned our workspaces. We also removed the cardboard and cleaned the space where the crate was drying once we submitted it. Here are pictures of the clean workspaces:

I am quite happy with how our final crate came out. I think it is well constructed, and I think we were able to have fun with how we designed it as well. Overall, we spent about 4-5 hours each working on the crate. We were able to put these into two 2-3 hour work sessions, including class time. We also used many different materials and machines. Overall, if we included the cost of machines, this project would be really expensive. However, we only used each machine for a short period of time, so I will use that as a measurement of cost. Our list of materials was 3 long pieces of 1×4 wood, 1/2 of a piece of 2×2 wood, and 61 wood screws. Our list of tools was a miter saw, an electric sander, various sandpaper, a drill, drill bits, a corner clamp, table clamps, a table router, a jigsaw, 3 cans of spray paint, and a belt and disc sander. All together, this is our cost analysis:

Item

Cost

Labor (~10hrs for both of us)

$72.50

3x 1×4 stock wood

$18

0.5x 2×2 stock wood

$2.61

61x wood screw

$9.98 (cost of a box of screws at home depot)

Total

$103.09

Item

Time

Miter Saw

15 minutes

Electric Sander + sandpaper + belt sander

60 minutes

Drill, drill bits, corner clamp, + table clamps

120 minutes

Table Router

20 minutes

Jigsaw

20 minutes

Spray paint

45 minutes

Total

280 minutes, or 4.7 hours

Our total cost came out to $103.09 and 4.7 hours of machine work. The majority of the cost was time we spent working and the time we spent on machines. We did our best to build the crate efficiently while ensuring we both got necessary skills. I think I learned a lot from this experience and will be building more crates.
