KDF: Kingfisher Digital Foundry

In my day job I'm a high school computer engineering teacher.  The subject is still relatively new and covers a ridiculous range of differing technologies, all lumped under 'computer technology' because they all have some vague connection to it.  While teaching it in class can be demanding, the upside is that in the decade I've been working away at it I've become familiar with technology well beyond my background in IT.  From electronics engineering to 3d modelling and 3d printing, I've had a front row seat to the evolution of digital technology as it rapidly expands and evolves in the 21st Century.

The other benefit of this front row seat is that I've gotten to work with some skilled teachers with diverse technical backgrounds.  From Jeff who was working in CAD and 3d industrial design when most people didn't have a computer to Katy the engineer who was one of the only people in our school board who could get the first generation of 3d printers dependable enough to actually use in class, I know some very technically adept adults.

Then there are my graduates, who have gone off to work in fields ranging from robotics and industrial engineering to electronics, IT and computer science; I know years of very technically advanced young adults who bring a staggering array of expertise and intelligence to the table.

On this cold and rainy March Break Tuesday in the middle of the COVID-19 epidemic, I'm wondering how we could leverage all that expertise and create a niche product that could serve a number of different markets.

I recently found myself frustrated by a lack of parts for the late '90s Honda Fireblade I was restoring.  Knowing that Katy has been using 3d printing to create prototypes in her class, including printing in flexible materials, I was wondering why no one has filled this gap as business proposition.  To replace one perished airbox rubber tube I would have had to pay to get four them shipped from a place in the UK at over €100; no one in North America had one.  I suspect Jeff could have made an accurate model in an hour and then Katy could have printed it in about 30 minutes.  We'd then have that model on hand if it was ever ordered again and could be filling individual orders for them in thirty minutes.  At $20 plus shipping for the part we'd be offering rare parts that meet specific needs for way less than the market is willing or able to at the moment.  For ten bucks more we could put initials or a symbol on a printed piece to satisfy the customizers.  Beyond the capital costs of getting the 3d printer needed, printing a part we had a model for is a quick and easy process and would only require maybe $5 in parts and power.

There are other angles to this besides micro-manufacturing old, out of production parts.  We could also create small batch bespoke parts for companies building prototypes.  By rapidly producing accurate, high tolerance parts, we'd also be creating a library of digital 3d model files that could also be part of the service. Those models could then go on be used in production.

Beyond the out-of-production parts market and assisting companies in with their prototyping needs, there is also the opportunity to pursue bespoke custom parts.  Within five minutes of the first time I saw 3d printed additive manufacturing technology, I started thinking about custom motorcycle fairings.  The default at the moment is to stamp out cheap copies of fairings, but it wouldn't cost much more to digitally redesign unique 3d variants of fairings and sell those, it would just need a large format printer.  Variations in ducting for people wanting to fit a turbocharger?  No problem.  Want to get really crazy?  A dragon scale fairing for a Game of Thrones fan?  This is a 3d printed fairing with scales that have depth and texture.  It would take custom motorcycle design to the next level, especially with a sympathetic paint job on top.

As far as the technology needed to create our digital foundry, I'm partial to the Formlabs 3d printers because they look like something out of Terminator.  They also produce very high resolution models. Their new 3L large format printer comes close to being able to make detailed, high resolution models almost up to a cubic foot in size.



The process of additive manufacturing (3d printing) is surging forward.  It isn't quite ready for the range of parts I have in mind, which would include being able to print 3d flexible parts that are fuel resistant, but this is more a chemical engineering bottleneck than anything else, and chemistry these days is rocketing ahead


I'm hoping that just as I'm ready to retire from teaching, micro-manufacturing will have caught up and I can retire right into another profession making locally developed and manufactured bespoke components in a micro-manufacturing facility of my own, Big Hero 6 style.


Front right is a holographic desktop and keyboard - not quite there yet, but I've got physical hardware that does the same job now.  The blue thing in the back right corner is a large format 3d printer - in the film he prints everything from carbon fibre armour to metal mechanical parts.  This kind of localized production will be the norm rather than the exception in the next couple of decades.  You can watch Big Hero 6 on Disney - I highly recommend it.

This isn't the first time I've kicked around the idea of applying emerging digital technologies to mechanics and manufacturing:

Yesterday I was out in the garage using a Structure Sensor to 3d model my motorcycles, there are so many things we could do digitally with mechanical engineering and manufacturing:

Chain and Agony, or, the End of Local Parts Suppliers

I've got to admit I'm a bit pissed off.  After trying to wrap my head around chains and sprockets online I decided to buy locally and have a chat with the parts desk at my regional dealer.  Since it was my first time doing a chain/sprocket replacement I figured I'd pay the extra cost and get some face to face advice.

Trying to get details out of the parts-desk guy was like pulling teeth.  He seemed frustrated with my questions and didn't offer up much.  I guess the logic there was, 'just bring it in to service.'  I left paying over $300 taxes in for what would have cost me $240 online, but was none the wiser.  I was at least assured that these were the specific parts I needed.

After a series of confusing and frustrating situations, here is the advice I wish the parts guy at the dealer had given me:

The Ninja 650r uses a 114 link chain, he gave me a 120 link chain but told me this was the stock chain especially for my bike.  He's not wrong, but he didn't tell me I'd have to 'break' the chain.  Here is how I wish it'd gone down:


You're going to need one of
these to break and master
link up a motorcycle chain.
It isn't expensive (about
sixty bucks)
Parts guy: "I'm ordering you the chain size for your bike, but it comes with six extra links.  When it comes in I'll get one of the guys to break the chain so it fits your bike specifically.  If you want I'll even ask him to do it when you come to pick it up so you can see how he does it."

He could have sold me a $60 tool (probably for more) and I would have left knowing what I was getting into, instead all I got was the exasperated face.  

When I hung the chain on the bike it was way too long (it was a 120 link chain going on a 114 link bike, but I didn't know that at the time).  I had to go digging to find out why the chain 'specific to my bike' obviously didn't fit.

This experience asks a larger question about brick and mortar stores versus shopping online: why would I spend the gas and time driving there and then pay the extra 20% for the experience if I can pay less online?  If there is nothing value added in me bothering to buy at full retail locally, then why would I do it?

Second up, I wish he'd have offered me some pragmatic advice for doing my own chain work:

Parts guy: "Is this your first motorcycle chain?  It's pretty easy to mess it up.  I'd suggest going for a basic O-ring chain for your first go.  If you botch the job you're only out fifty bucks and you've learned something."

I ended up buying the bells and whistles X-ring chain on his advice, and then breaking it a link too short (after looking up how to do that on that paragon of customer support, the internet).  It's an expensive learning experience breaking a chain so that it doesn't fit my bike.  At least it's still over 110 links and a 520 sized chain, meaning it'll work on a lot of other bikes.  Now I've not got to decide whether to seal it up and wait for an ideal use or try and resell it (at a loss).

One way or another, I don't think I'll be driving down to the local dealer again for parts, I get my questions answered with more patience on the internet, which beggars belief.

Note:  a couple of days later I went online and picked up a basic O-link chain from the same Japanese chain manufacturer from
Canada's Motorcycle (35% cheaper than the equivalent chain from the dealer).  In a matter of moments the chain was on its way (free delivery).  It got here in the same amount of time it took the dealer to order it in (but I didn't have to drive down to the city twice).  I'm all for buying locally and helping out the area economy, but if local business don't realize how they can add value to a local buying experience they're going to kill it stone dead.

Note²:  maybe it's only a motorcycle dealership thing.  I went to RONA to make an order for deck parts and they couldn't have been more fantastic, same with Universal Rentals in Fergus, equally awesome customer service.  Are motorbike shops just too cool to care?
