Trog Tetris

July 23rd, 2008

I cut out a few rusty sections of the floor a few months back.    Yesterday, I finally started replacing them.   Here’s a shot with the 1″ square tube floor “joists” welded in place.

Luckily an L shaped piece of 14 ga steel fell into place, after a careful rotation.

I’m hoping a rectangular piece is next.

Overhead welding sucks, so I’m going to drill holes in the sheet metal and weld to the joists from the top, rather than from below.

Here’s a blurry pic of the new panel with holes drilled and weld-thru cold galvanizing primer.   The primer has zinc in it, to minimize corrosion in the space between the panel and the support pieces.

I also removed the cowling covering the rear portion of the engine and transmission and cleaned all the rust off of it.

Cheezbrgr vs Cheezbrgr

July 1st, 2008

In the catagory of unnecessary data I don’t need, I performed tests  of the outputs of the old cheezbrgr lights compared with the new LED lights.    I placed a piece of white Sintrel 1 meter away from the lights.   There was some ambient light in the shop due to the skylights.    All pictures were taken with a Canon 30D 1/45sec F 1.8 with a 35mm lens.

In each picture pair, the top one is old incandescent and the bottom is LED.   Pictures were taken off axis by about 1 meter and from about 2 meters away.   (I had a prime, non-zoom lens on the camera and had to step back to capture the illuminated patch.)

Tail light:   The only test where the results were pretty close, though the LED seems to be hotter in the center.

Brake:  Here the LED light is radically brighter.   This is the case that matters most, I think.

Turn Flasher.   Again LED better — I could barely see the incandescent flasher on the Sintrel..

And finally, a comparison of the incandescent tail and brake light vs LED brake light (night braking)

I didn’t test the reverse lights.
