Meet Zaphod…

Tuesday, August 26th, 2008

…the camera. He has two lenses, one in the front and one in the back–one of which can be tucked away, you know, when he just wants to look like a box.

So I’ve already taken my camera out for a few spins. The results thus far have been amazing. When I took my first two shots, I had no idea what to expect. I was worried about light leaks or focusing problems between the surface of the ground glass and the film. To my delight (and surprise), the first two shots came out close to perfect.

And now I really have to say…I’m addicted.

Finishing the Camera

Tuesday, August 26th, 2008

After spending nearly seven months on this project, I decided that August would be it. I needed to finish the camera before my photo class’ landscape shoot. So in one big effort to do that, over the span of one week I oiled the cherry, polished the brass, and plopped together some bellows (still looking for the right material, but blackout curtain, painted black, was what I used).

Keep in mind I was also working full time every day, so this was *not* an easy task.

I took a lot of shots throughout the night, mostly in an effort to create a time lapse video in the future. Here are a couple highlights:

All of the wood pieces are laid out. I spent an entire evening sanding each piece, first with 80 grit, then 100 grit, then 150 grit, then 220 grit sandpaper.

The Final Bits of Construction

Monday, August 25th, 2008

Here are some photos from the final phases of construction of the camera.

The font standard–a little buggy but it works.

A Teaser…

Tuesday, August 5th, 2008

After pulling an all nighter on *Friday* night, folding the bellows the morning of my first shoot, and attaching the bellows on location, I’m pretty exhausted. I just finished developing the film last night–my first two shots!–and it looks fantastic! No light leaks, and it’s just beautiful.

Anyway, here’s a few quick photos from my first shoot. I’m trying to compile more detailed posts of the last part of the construction process as well as the assembly of the camera. I’m just extremely busy right now…but hopefully I can get *some* work done on the train to DC this weekend.

a closer look

Saturday, May 10th, 2008

Last Wednesday I woke up rushing to turn in my 6.002 p-set. Since it was a pre-lab I needed a copy of it for reference, and I didn’t feel like scanning it and being 15 minutes late to recitation. So I took out my handy Nikon D70 and took some quick shots of the pages.

I got to the last page…*chunk..ddddrrrr* *flisp* *flisp*

The. Shutter. Is. Not. Opening.

Mirror. Not. Flipping.

Camera. Broken.

Yeah…how anti-climactic is that? The last photo you ever take is a .002 pre-lab. I knew you were dangerous course 6! Psh.

Anyway, while the camera is off to Nikon to be nursed back to health, I’m borrowing The Tech’s d300 (drool) to document the building of my 8×10.

Macro shot, anyone?

wibbly-wobbly, timey-wimey

Saturday, May 3rd, 2008

There is very annoying thing that happens to a project as you start closing in on completion. All of a sudden all these little nit-picky details that each take at least 30mins to do pop up. Like hey…I need to cut slots, I need to cut screw holes, I need to recess the wood here, I have to mill that..

What consoles me is the fact that, hey, this thing is starting to look like a camera. I seem to have this crazy idea that I’ll finish it during finals week—my two finals are on Monday, so once that’s over I’m freeee! But, no, I really mean finishing…as in finishing the wood…polishing the brass.

Hey, I like to be optimistic. If it doesn’t get done? Well, I’m signing up for a year membership to the hobby shop anyway.

Machining Brass

Friday, April 25th, 2008

Perhaps the most time consuming part of this whole endeavor is milling, drilling, and filing all of the brass pieces. It definitely puts a whole new perspective on things when you start looking at all the little pieces of machined metal all around you. Although most of that work is automated now, it really makes you wonder how anything got done back in the day when files were the most readily available thing.

Making a hole in a piece of brass takes three steps. First, you need a center bit to drill a small hole right where you want it. For most of my pieces, precision isn’t necessarily required, so I’m eyeballing hole placements with a drill press and some scratch marks to save time. When precision is required, a milling machine is definitely needed.

The focusing rack

Tuesday, April 22nd, 2008

Now that I’m comfortable with most of the machines at the hobby shop, the progress on the camera is definitely increasing in pace. This week I’m wrapping up work on the focusing rack and starting on the front standard.

  • body
  • base
  • focusing rack
  • front standard
  • ground glass and negative holder
  • finishing

I can confidently say that I’m finishing up the toughest and most complex part of the camera. I’m also hoping that my ground glass arrives soon so I can finish up some simple things on the ground glass and negative holder frames.

Here is what the camera looks like so far.

Brass!

Friday, March 28th, 2008

The end of February and beginning of March was spent trying to find all the necessary hardware before I could move on with the rest of the camera. I was able to scrounge up most of my brass pieces from McMaster-Carr and SmallParts, but I was delayed in finding a brass rack (brass pinions were everywhere). Eventually I found it right under my nose at McMaster-Carr after some user interface issues (Biyeun!Fail). The whole incident is quite embarrassing.

With the brass finally available, I spent most of March learning how to machine the parts that I needed. I also spent most of March realizing that I was a Physicist and not an Electrical Engineer, and the whole process of switching majors left me without much time to take photos of the machining process (but I’m sure I’ll have some of those soon).

A week after add date, I also decided that, with all this work put into the camera, I really ought to receive some credit for it. Unfortunately, this idea came the night of the Spring for-credit UROP proposal deadline. But after some emails, I was able to get a proposal in by the following Monday. Now I have the best UROP ever, with Thery Mislick (from the Edgerton Center) as my supervisor.

I assure you…more is to come.

Not another mitered frame

Friday, February 15th, 2008

The beginning of February was dominated by mitered frames. I had three to build: one for the base, one for the film holder, and one for the ground glass. Unfortunately, the shipment of my ground glass was going to be a little delayed, so I left the frames for the film holder and the ground glass unfinished.

An example of one of those frames.
