Christmas Gift Making


I wonder if I was a Santa Elf in one of my previous lives...

It's nearly time for some keen folks' mid year Christmas, so probably about time for the 2013 Christmas gift making round-up.  For someone who is a fist shaking festive grinch, I sure do put a lot of effort into designing and making gifts for family.  It the only way I can think of to turn something I loathe, which is shopping for gifts into an enjoyable experience, which is creating something in my personal sweatshop - *ahem* - workroom.

Last festive gifting involved printing some photo books, making some food and the usual sewing and toy making.  There seems to be an emerging theme of DIY toys, clothes, food and photography.

I should be about the last person in the western world to want to do this, but I even sewed a holiday outfit for my daughter.  Red and white happen to be her colours, and my weakness for elephants compelled me to buy elephant print cotton

'71 MGB Race Car Clock


The making of an analogue time piece.
A bit over a year ago we rather ambitiously went on a frenzied but rewarding mission making everyone's Christmas presents.  I managed to document some of the projects in a timely manner, but lost steam half way through, letting the process photos gather the digital equivalent of dust and cobwebs.  Perhaps, it's time to unearth another one of those undertakings.

One gift I didn’t have to think hard about for a clock for my other half.  Well, there was a lot of thinking involved, but that involved resolving the design details as opposed to coming up with the concept.  We have a garage/workshop, which is my husband’s greasy second home.  He didn’t have a clock and couldn’t get his phone out of his pocket with filthy hands to check the time, so there were frequent issues with punctuality, especially around dinner time.  I set out to resolve this persistent concern with something of design significance to this wonderful man: his 1971 MGB race car.

I had the design finalised by mid November and cut the first prototype.  I gleefully patted myself on the back for being so organised with the whole Christmas whatsitnow.  The plywood clock face had the design engraved into it, and then the design was cut separately out of card and inlaid into the wood recess.  It worked perfectly, so I sent the files to the fabricator to have the inlay components cut out of brass.  After not hearing back from them for a few weeks, I got slightly anxious and called them, only to be told that they couldn’t cut brass and that they had emailed me about the issue.  The email must have been eaten by the internets because I never received it.  I really wanted the vintage look of brass, but by then it was too late to find another fabricator, so I made the decision to use stainless steel instead.  At least that would match the chrome of the car.

I firmly decided to avoid a last minute mad making panic A La Design School, so I forcefully crossed my fingers in hope of getting my parts back on time.  I couldn’t work on any other components until the metal parts arrived, so when I was told ten days before the deadline that my files were unreadable (despite being especially converted for industrial CAD cutters), I developed a persistent twitch to accompany my morning sickness.  What followed was a series of phone conversations with the fabricator where I had to convince them that the design was to be cut exactly as specified – I’d already prototyped it, and it worked, and no extra bridges were needed.  Yes, yes Cut As Is, Please I Know What I'm Doing scenario.

Finally, on the 21st of December, at the end of the work day, I had the parts personally delivered by the lovely factory manager.  I gave him tasty jam to say "thank you".  
Thank You jam
I spent the next morning frantically and painstakingly grinding off the unavoidable bridges between the laser piercing points to get my parts out of the unyielding sheet.  I wished I had a Dremmel and not a gutless little rotary tool.  Anyone who’s worked with stainless steel is familiar with its pervasive attribute for eliciting coarse language.  After much swearing, sweating and bleeding I had all the metal bits separated and laid out.  Fortunately, the parts turned out about 95% accurate to the design, which meant only minor tweaking of the original drawing to get the engraving of the clock face identical to the unchangeable stainless components.

Next came the inlay prep work.  Firstly, when you laser cut wood, you can't just grab the cut part and expect it to be good enough for a product.  I see those examples in the market place all the time, and it bugs the hell out of me.   A laser beams is basically a very concentrated fire.  It burns.  Intensely.  People seem to be surprised by that.  The heat causes charring on the material surface, in the direction of the pull of the extraction.  Quite a bit of sanding is required to tidy up the laser cut parts.

After all that grind, it was time for some serious effort to inlay the springy, shiny steel parts into the engraving without making a mess.  Getting the intricate MG cut-out to stay flat was remarkably difficult and incredibly frustrating.

Oh the terrible glue mess!

Next step is sealing the clock to make sure that the wood lasts well.  I  decided on a spray lacquer.  Unfortunately I couldn't get into a ventilated paint booth, so had to do the spraying outdoors, at the mercy of Wellington wind.
Deciding between a wax and a lacquer.  Wax and metal should have been quite obviously a dumb idea.

I was on the receiving end of some suspicious looks from people who must have mistaken me for a tagging delinquent.  Several lacquer coats later the clock face was ready for its pointy hands.  I bought a cheap clock mechanism and swapped its paper thin aluminium hands for my custom cut ones.  Two days before Christmas the clock was finally complete and ready to be packaged into an insanely beautiful box made from some cardboard scrap.

Gifting That Was

We've already made a little dent in the new year, but it seems that only a few days ago it was still full on making of stuff to shove under the plastic tree.  Previous Christmas involved much much making, but this one was scaled back in comparison, though still shopping-free.

Rubik Desk


My birthday gift: a DIY computer desk to replace the handy but unstable old one.  I love it!  Rubik the Retarded Raven is laser engraved into the plywood.  The best thing about the desk, aside from its functionality is that it's made entirely from waste material.  The plywood used to be part of our rotten walkway that had to be replaced with something that didn't feel like quicksand.  The base of the desk is made from short scraps of steel tube welded into a continuous longer piece.

Arachnid Bowl



Some plywood, glue, tools...  Oh wait, no glue and no tools!  Simply slot the pieces together, and in a couple of minutes the flat cutouts are transformed into a 3D bowl that is perfect for all that nutritious fruit.  Mmmm vitamin C.  Yum.
 
 One thing of note is that when assembling the bowl, it helps to apply the pressure right on the joint to avoid stressing the material.  Once assembled, the bowl is strong, but the individual ribs are fragile on their own.

More free designs on Thingiverse

The blogging silence hasn't been reflective of my design work.  Here are a few designs I've produced recently.  They are all available for free from Thingiverse.


Jewellery tree made from American Cherry veneer MDF:


Nested Animal puzzle made from Earth-friendly bamboo.  This is like a jigsaw puzzle, but it's made from all kinds of animals that snuggly fit together without any carnivorous carnage:

Tulip Vase made from 4mm plywood.  A test tube fits snuggly inside to hold flowers or some such:

Wishbone Candle Holder made from 4.5mm acrylic.  Two halves slot together to form the 3D structure:

Dinosaur


Project: wheelie dinosaur for a four year old with a dinosaur obsession - inspired by WoodMarvels
Materials: flawed 10mm poplar plywood, dowel.
Constraints: fit on the material scrap.

Our four year old nephew is an expert in two things: dinosaurs and diggers.  I figured that a spotted dinosaur on wheels would make a sweet present.  The idea of the WoodMarvels layered profiles was a good starting point, and it was a pretty straight forward project that fit on a small sheet of 10mm Eurolite Poplar plywood.  The material wasn’t suitable for Personal Factory making because it had gouges and bog on one side.

The cut design was sanded, glued together and waxed.  The wheel axels were the only non-laser cut component, but were cut from dowel instead.

  The toy was an awkward shape to wrap, so I made a quick box for it.

Flat Pack Fruit Bowl

 Intolerance.  Well, that is more or less what happens when you design interlocking parts that require decent tolerances, and the material scraps used in fabrication all come from different batches.  I decided to make some flat pack fruit bowls to use up some of my plywood offcuts, but the first bowl was to be made out of red tint acrylic for a ruby wedding anniversary present.  Acrylic is definitely not the ideal choice for something that is a combination of a) delicate, b) has lots of interlocking joints, c) will be handled a lot.  However, in this case it was more about aesthetics because the bowl was to be an exo-skeleton for a clear glass bowl.  The main design challenge was making the lasecut bowl fit precisely over the contours of the glass bowl.  I made the initial prototypes from corrugated card to test out whether my idea and contouring was going to work.  Once the acrylic design was finalised, I tweaked the form for a plywood version.  The files for the latter can be downloaded for free from my Ponoko Personal Factory showroom.  These customised if required and lasercut.
