Countdown to Woodworking in America

Only one week left before immersing myself in all that is woodworking.  I never expected the degree to which this event has amped up my anticipation.  I have been so preoccupied with dreaming about the event that I have done pretty much nothing of value out in the workshop, instead favouring hours of time online.

Online?  Strange as it may seem, there are a few aspects of this event that seem to keep me tied to a computer for hours on end.

  1. Reading and re-reading the workshop descriptions and pondering what I want to get out of them
  2. Vendors, vendors and more vendors….should those S’s be $’s?  Yes, like a kid with the Sears Christmas Wish Book in December…I drool over handplanes that are worth more than my car, ponder how much money is involved in making me a better woodworker…the correlation of tool cost to skill is exponential is it not?
  3. Keeping up with the general buzz around the online woodworking community.  While maybe not everyone is going…everyone is talking about going and wants to go.

So, tonight I have to get myself off the couch and into the workshop, even if it is to dig around in the scrap bin for the Scrap Exchange that is being planned online. 

I am in between projects right now and am justifying not doing much on a new project until after my skills have reached new heights from all the skill I will develop through osmosis at WIA….and of course from the new tools I’ll come home with.

Apart from a laundry list of shiny new tools which in reality will be much shorter once reality hit$, I do have some concrete objectives that I hope to get out of this trip.

  1. I’m new to most hand tool techniques (watched too much Norm and not enough Roy) – but I want to see how the basics are done and try to incorporate as much of them into my next project as I can
  2. Design – understanding the way that one applies design methodologies and get a better handle on the creative process
  3. Above all else, meet up with and generally harrass as many of these other crazy woodworkers who are spending entirely too much time online, but loving it nonetheless.

Just a few more sleeps…..maybe enough time to grow a beard.

Marble Tower – for charity?

The marble tower is done and making a home inside the house (sadly no more playing in the workshop, back to work). 

A few years ago I came across a marble tower that was bigger than the one I made, but conspicuously similar in design.  It was in a restaurant and had a gumball dispenser on top that was presumably for charity purposes. 

Coincidentally, I came across the very same thing a couple of weeks ago, although the sides are encased in some sort of plexiglass type material to protect it from the public.  The money collected was to go to a local hospital and if you got a black gumball, you won a prize.  My daughter gave it a try.  The gumball wound its way around the various ramps and mechanisms (making far less sound) and ultimately depositing the gumball in a receptacle at the bottom.

What do you know, my daughter got the black gumball and won admission to the pumpkin-land they will set up this fall.  Cool!

I snapped a couple of blurry pictures (sorry) as you’ll see below.  It appears that an entrepreneur has worked out a CNC method for producing the parts for these marble towers and produces them as needed for charity gumball dispensing. 

I actually googled something like ‘charity gumball tower’ and was able to find one source for these….starting at over $1000 each.  While, I would go poor selling the one I made at such prices (labour costs coming in below minimum wage), it is interesting to note that something that starts as a handcrafted item can be produced through a mostly mechanical means at a cost that is viable from a business point of view.

This has me pondering the differences between Production work and what could be considered Research and Development.  After developing the process of building something can you recover that cost through the subsequent mass production of the item?  This would be an interesting exercise in developing a business plan around the initial cost of developing a piece of custom woodwork and then selling replicas of it at a level where the R&D costs are recovered in a short enough time to start generating profit on the items.  Hmmm!

Of course, this flies in the face of a custom woodworking business where the customer is buying the item in part because it is unique.  The question then is where does type of approach fit in?  My neighbour made a few bucks off of mass produced mirrors and rocking horses by hocking his wares at various craft shows and fairs, but this is not a viable business model.  This obviously isn’t how the greats did it…but then they have something the rest of us might just be missing (aside from thinning hair, I don’t see a lot of Sam Maloof when I look in the mirror.)  Then there is always the question of what ‘custom’ really means, it’s a big world out there, especially on the internet..can more than one person be willing to pay a lot of money for their own ‘copy’ of a custom piece?  I digress, perhaps I’ve been reading too many articles on making woodworking a business.   What would Adam King say?


Marble Tower – finished!

Yes, it is finally done.

Before I get to the finished product, I did have a few things to touch up before I even got to the finishing stage.

Final touches:

– the loading mechanism at the top needed some fine tuning and I decided to cut out most of the plywood in the supporting structure for it…it looked strange to me having a big piece of solid material right at the top.

– in a few places I needed to embellish the rails with bumpers to keep the marbles from making a premature escape from their noisy adventure.

– several screw holes needed to be plugged and cleaned up.

Once these steps were done, I had a whole lot of finicky sanding to do.  A good lesson on something like this is to prefinish all that you can.  The first 3 or 4 coats of varnish were wiped on (regular varnish thinned down with mineral spirits and applied with an old cotton sock), followed by a final coat sprayed on (spray can…not HVLP… 😦 ).

I left the finish to cure for a couple of days and buffed it out with a ‘000’ scotchbrite pad (couldn’t find any ‘0000’).  The handful of moving parts also got a light coat of paste wax to keep them from sticking.

…..and…(drum roll)…ta da!

 

There’s nothing quite as satisfying as completing a project.  When it’s something you can actually just go ahead and use right away, it’s even better.  But when it makes lots of noise, then it’s just awesome!

I’ve got three videos for you:

Video 1:  A tour of the tower.

Video 2:  The full effect (and my ugly mug to boot).  I’m also playing with actually editing video (which I can see is going to suck up lots of time if I start doing more videos)

Video 3:  A few close-up shots of the various parts in action.

This entire process had its ups and downs and suffered from some serious procrastination, but it was fun and I learned a lot from the process.  I was able to try out a couple of new techniques and now have a fun toy and interesting conversation piece.

Hmmm..so, what’s next???


Marble Tower – decisions, decisions

I could go on about great planning and thinking ahead and any number of good reasons for why I went ahead and put the bottom mechanism in place long before I was ‘supposed to’…but in reality, it looked like fun, so I jumped ahead and did it completely out of sequence.

Having done this out of sequence turned out to be quite helpful when I was doing the short and winding road in the previous post, since I didn’t have to guess or calculate how high it had to be when it ended, nor did I have to figure out a way to attach it.  Yea me!

This part looked like fun to me, kind of like a small section of a mechanical binary counting machine you’d find in a kid’s science museum.  Ok, I’m probably reaching, but it evoked that kind of feeling in me.  Basically the divider flips back and forth between the two tracks, using the marble’s weight to move the divider as it passes by.

I pretty much followed the plans to a T for this part.  Well, except for the little trough at the end where the marbles rest….you can’t expect me to do a whole section by the book!

No real significant challenges in this part, just a lot of thankfulness that I’ve got a bandsaw, without which I am dead sure I would have done it differently…as in not at all. 

The one area where I spent some time and did a mock-up was on the little cog-wheels.  I wanted them to be the same and had a bit of trouble making the first one look just like the template, and it ended up a little off balance in the end.  From the exercise of building one, I figured out a more straightforward way of cutting them on the bandsaw.

The plans were to have a wheel with four spokes 90 degrees to each other but each with a slight curve to them, with a cylinder stuck on the end of each spoke to catch the marble.  This is a little tedious to do, at least with my tools….(feel free to read that as skills instead of tools).  So, instead I made each spoke a bit more like a teardrop shape, which was both easier and to my eye, a little nicer – less like the old erector sets.  The cogs spin freely on some thin dowel material (bamboo skewer to be exact), which I later trimmed down and capped off.

Instead of the planned for trough, I decided to let the marbles collect in a triangular pen.  I took some 1/8″ strips of ash and glued them from the uprights back towards the center where they intersected with this last mechanism, as well as one strip across the front to keep the marbles in place. 

 I tried dry fitting the triangular pen in place and it looked pretty good to me, so I glued them down.  Yes kids, it’s lesson time!  Dry fit…glue…sounds right.  Oh wait…there’s a mechanical activity happening somewhere in there too…a marble is supposed to be involved.  The plan should have been:  dry fit – TEST – rethink – dry fit – TEST – glue.  Insert sheepish look.

Apparently the marbles are able to bounce just high enough to hop over the ash strips, only to be found several minutes later with a telescopic magnet on a stick – buried in wood shavings under a cabinet.  After several such tests and some R-rated language I cut an additional strip to increase the height enough to bounce the marbles back into their pen.

Yes, this was done out of sequence (as you can see this part without the bell and winding road)…which I will claim was planned out for your viewing pleasure.  🙂

This was the last step in build process, but I am still far from ‘done’.  The tower now actually works, but there are some glitches and there are a few things I have to go back and revisit as well as some trim work.

My next update will include some pictures of the finished product along with a flawless execution of 10 marbles through the dispensing mechanism and all subsequent ramps, toys, bells and xylophones, to end with a pile of marbles nestled in the triangular pen with nothing but the faint pealing of the bell to give away the maelstrom of activity that just took place.  Too dramatic?  No…just you wait…you’ll see!

Still don’t believe me?  Ok…here’s a teaser….and if you watch carefully at the end you’ll see my issue with the inadequate front pen rail.
