Pallet Deconstruction Workshop

These days, there are hundreds of websites providing interesting project ideas made from pallet wood. But taking apart a pallet is not always an easy task – and can leave you with more scraps than materials.

In this workshop, learn different methods of effectively taking apart a pallet. Come away with a stack of pallet materials for your next project! Bring along a pair of work gloves if you have them.

About the Instructor: While no expert woodworker, Amy has deconstructed her share of pallets and is enthusiastic about using pallets to make all sorts of things: from bookshelves to tables to dartboard cabinets.

Max: 6 participants     Members $15  |  Non-members $20

Member’s project: Judith’s Kitchen Facelift

YuKonstruct member Judith sent us the following story about sprucing up her kitchen with a little help from the tools in our shop.

The kitchen before re-finishing
The kitchen before re-finishing

For quite a while I wanted to renovate my kitchen.  The wooden doors were faded and rough looking and needed some TLC.  I never got the time and the tools to do it until recently after I talked to a volunteer at YuKonstruct.  I asked him if he thought I could sand down the doors and re-finish them.  He encouraged me to do so because there is a big sander in the wood working workshop I could use.

When I brought in my kitchen doors after a few days Logan, YuKonstruct’s facilities manager, had a look at the doors and we made an appointment for an evening to get the job done.  Logan was very supportive.  He showed me how to work with the sander and helped me put the first few items through the machine.

After the doors were done they already looked better than before.  The next weekend I painted the doors and installed them complete with new knobs that matched the counter.  Now I have a beautiful kitchen again!

It is great to have a place like Yukonstruct with all kinds of tools and help available to make things happen I could not do otherwise.

Member’s Project: A Telescope Built From Scratch

Why don’t you just buy one?

That’s a question I’ve heard countless times, and when it comes to building a telescope, you really have to think about it twice. After all, buying a decent telescope is quite easy and relatively cheap. You can get a good view at the moon, the planets and some galaxies for a few hundred dollars including shipping to Whitehorse. On the other hand, building a telescope is an arduous task; you have to find the materials, build your own tools and spend hundreds of hours around a polishing stand. it also involves a lot of patience and precision. At first sight, anyone sensible would take 15 minutes to place an order on-line and wait for the telescope to arrive. Well, call me crazy… I chose the DIY option.

The starting point: a blank of borosilicate glass

As a maker, I always favor building over buying, even if it costs more money for the final product. You simply can’t buy the pleasure and knowledge that you gain by building something yourself.

Making the mirror of the telescope is the most time consuming part but also the most interesting. First, you need to order a circular piece of glass with a low coefficient of expansion (pyrex, zerodur, borosilicate, etc). Then you need to build a circular tool out of waterproof plaster, cover it with tiles and rub it against the glass with silicon carbide in between. Using finer grit will slowly make the concave surface smoother. Once you’ve reached the desired sagitta, you can polish the surface using a different tool; this one is covered with pitch and the polishing agent is cerium oxide. When you have a nice polished surface, you need to transform that spherical surface into a paraboloid. This is where the time consuming part begins. During that step you will remove a minute amount of glass to approach the perfect theoretical shape. If you complete that step successfully, your mirror will have a surface so regular that if you were to stretch it to the size of a football field, the highest default would only be a thousand of an inch high. Of course, to control the surface with such precision, you need to build a special instrument which takes even more time and material.

When you’ve reach that step, it’s already been a few month since you began the project. However, if you managed to reach the desired precision, you most likely have a better mirror than most commercial mirrors.

Once the mirror is complete, it is sent for aluminizing. During this operation, a thin coat of aluminium is evaporated onto the surface of the mirror; this requires a vacuum pump and a high voltage source. As much as I would like to do it myself, I reckon it is not really worth building an entire vacuum chamber for a single mirror.

The focal length is measured on the finished mirror.  We will use this measurement to design the tube of the telescope. I wanted to use something nicer than plywood so I went for red cedar trims that I resawed to get 1/4″ boards. These boards where assembled together using bird’s mouth joinery to form an hexadecagonal tube (16 sides). Some baffles were laser cut on YuKonstruct’s Epilog laser cutter; these will prevent internal light reflection. The tube was then painted black inside and coated with several coats of spar varnish to make it dew proof.

The last step consists of putting everything together. A hole is drilled on the side with a hole saw to accommodate the focuser; a cell is built for the primary mirror and a support is made to hold the elliptical mirror in place. I went with a curved vane for the ease of build and for the fact that it will limit diffraction spikes around bright stars.

As I was busy building other things, it took about a year to complete the instrument. On the first afternoon after completion, I tried to locate Jupiter in the evening sky; it took about 5 minutes to spot it with the naked eye because the sun was still shining bright above the horizon. Once I found it, I aligned the scope and focused on the planet. As a first observation, I didn’t know what to expect. Well…turns out I saw details on Jupiter that I never saw before on other instruments.

I am now really eager to try it on deep sky objects on a dark winter sky. Next project: make a proper stand for the instrument.
