I accomplished a number of small tasks this weekend – working on a plate polishing holder, charging up an iodine box – but the little exercise I thought I would post on was the test I did for mercury fumes. I wanted to test the new Mercury Indicator Powder I got from Lab Safety Supply. A while ago a dear friend gave me some mercury in support of my dagurreian passion. It was an item he had picked up out of curiosity many years ago as a young man and had carted around with him from place to place. I don’t know how he had it stored when he had it, but it came to me in a polyethylene eye wash bottle sealed inside a gasketed Army surplus ammo can. I was curious to discover if polyethylene is mercury vapor proof. Read more »

Having some time off from work. Have created what (I hope!) are the final cutting templates for the stainless steel dag plate project. Also picked up an odd Packard type shutter on e-Bay that I may try to replicate in acrylic. Also spending some time on finalizing the sixth plate camera and experimenting with creating [...]
- Two days of laser prep

Two straight days of prepping plans for laser cutting. Steel plate cutting templates, lens mounts and film holder mounts for the B&J 8×10 and some experimental 35mm plate holders made out of 1/32 ABS. Not quite done, but should be good to go when Pagoda Arts reopens after vacation time. A great leap forward.

Did a dry run today of the new plate cutting templates at Tech Shop. Ran into some problems with the first cut and had to back off on the production run. Need to make some template adjustments. The good news is that the cutting is three times as precise as it needs to be. Finished [...]

Have been slowly moving forward with my experiment to create stainless steel based plates. Today I plan to finalize the cutting templates so I can cut up the 1′x2′ piece I had plated. The plan is to use 1/16″ acrylic laser-cut templates to guide the cutting on the 40″ hydraulic shear at TechShop. The real [...]
