Dog Weight Scale Part 3: the Woodworking and Assembly

In my previous post I described the electronics of the Dog Bed Weight Scale. In this post, I’m doing the final woodworking and assembly – at least enough assembly to test the thing.

First I needed to design some sort of support for the load sensors.  Because of the design of the sensor – a “T” bar surrounded by a “C” shaped bar – I needed to make blocks that were 1) tall enough to keep the top piece of plywood from resting on or crushing the electronics and 2) cut out to allow the “T bar to bend below the “C” shaped part as weight was added.  You can find plenty of videos of people trying to use load sensors by mounting them on a flat surface; that won’t work.

Dog Weight Scale, Part 1: Cutting the Circular Base

I want to learn how to use Load Sensors to continuously weigh stuff with an Arduino, so I thought it would be fun to continuously weigh our dog, Pippa, while she sleeps in her bed each night.  The project is a little like Nate Seidle’s Beehive scale, but simpler.

The idea is to turn Pippa’s bed into a scale. Pippa’s in fine shape right now, but it’s always good to keep an eye on your dog’s weight, and a custom-made scale is a great way to do it.

How to Make a Drill Press Table

As multiple woodworkers have mentioned, a drill press as-is is poorly suited to doing woodworking: the cast iron table can transfer grease to the wood; the table is small; the table has limited places to fasten clamps to hold the wood down.

So here I am making a drill press table.

I started with a sketch based on this drill press plan, with an offset waste plug circle from this nice design.  I’ll narrate the project as a “how to” from here on.

Adding a Finish to the Glockenspiel Case

Previously I finished the labels for the glockenspiel. In this post I literally Finish the case.

Last weekend and this weekend are nicely warm enough, so I’ve put a few coats of Minwax gloss polyurethane  finish on the Robotic Glockenspiel case.  In a few days the finish will be dry, and I can do the final fine-sanding (to remove dust captured in the Finish) and assemble the thing.

P.S., don’t copy my style of finishing – I’ve not learned how to do it well, and here I’ve not done most of what you want to do to make it come out right. I haven’t put down a drop cloth or newspapers to keep the surroundings from being Finished; I haven’t used pinpoint-tip stands to keep the work from sticking to the support table; I haven’t sanded between coats to remove dust/pollen; I’ve sprayed when it was breezier than it should be.

That said, I expect it will turn out well enough for this first-prototype, and functional enough to keep dirt from getting into the wood. (How many times have I said “the end is in sight”?) The end is in sight!

Next I complete the project at last!

Final Labels for the Glockenspiel Buttons

Since trying out woodburned labels, I made another attempt at scrollsawing the button labels for the Robotic Glockenspiel, and am happy enough with the results that I’ve glued the labels to the glockenspiel box. I’m so happy to have finally made up my mind – whew!

So this blog is a sort of “how to scrollsaw” in a nutshell.

Scrollsawed Button Labels for the Glockenspiel

Since putting a lid on the glockenspiel case, I’ve been wrestling with exactly how to label the robotic glockenspiel buttons: If I had a laser engraver I probably would have engraved (woodburned) the labels on; sticking paper labels on could look pretty sloppy; decals sounded like a production of their own, with the risk of gumming up my printer; painting the labels would require a steady hand; woodburning by hand is another option; so is gluing on scroll-sawn raised labels.

So today I tried out my new (used) RBI Hawk 220 VS scrollsaw, that I’d cleaned up a few weeks ago.

Putting Hinges, Lid on the Glockenspiel

Since fixing the sound of the chimes,  I’ve been finishing the software for the glockenspiel. Now all the buttons work: on/off, play/pause, skip back, skip forward, and shuffle. Woohoo!

Today I made the lid, attached the molding on the edges of the lid, attached the piano hinge and attached the side hinges. It’s not fine furniture, but I’m learning a lot about how to make The Real Thing. For example, don’t sand the wood with the sandpaper you used to remove rust from your new scrollsaw (ouch!).

All the hardware (except the front latch and the feet, which should install easity) is now installed.  So now I’ve taken all the hardware off so I can easily do the labels and spray the finish.

Next I plan to label the buttons – I plan to try woodburning – the end is in sight!
