Lasersaur, the new open source laser cutter from Nortd Labs. Finally a precision cutting machine within reach… (a long reach, but at an order of magnitude less than prior costs for an equal sized machine). Check it out at at http://labs.nortd.com/lasersaur/
Now I’m off to the laser cutting class at TechLab SF.
First visit to TechShop San Francisco yesterday for the Angular Sheetmetal class. Got checked out on the 50 inch hydraulic shear, the similarly sized bending brake, a Beverly and straight manual shear, turret punch and spot welder. Part of the long trail of getting a better source of plates. TechShop is a fantastic resource. I’m not sure I have enough free time to make membership worthwhile yet, but I do plan to keep taking classes and perhaps going on a day-use basis if that is allowed. TechShop only has a few locataions in the US, but it is well worth checking out if you are anywhere near one. The URL is http://www.techshop.ws/index.html
As firsts go, I’m reasonably happy with it. My first mercury developed image on a traditional silver plate – a little over three years since I started. Since I can only devote a few hours a week to making progress, I’m OK with that. Lots of problems of course - underexposure, issues with the polish, wet process marks, you name it. But I can see it and it didn’t take me multiple tries to get there. Perhaps taking a picture of the Goddess of Mercy was a good plan. A hundred more to go (give or take) and maybe I will be at beginner status. This one is fumed with iodine only for 33 seconds to the first light golden yellow, exposed 10 seconds at f1.7 in 15 EV full sun outdoors. Developed over Hg at 100 Deg C for 10 minutes. For a the whole picture in a slightly enlarged view see here. Now I just need to figure out which of the problems to tackle first….
I have been working for a while on a prototype sixth plate fuming box to replace one I had. This one is unusual in that the iodine and bromine containers are movable and can slide under the plate without having to move it from box to box. It is constructed of modern materials (Acrylic and Type II PVC). It also features a laser cut acrylic plate holder that is designed to mount directly onto an 8×10 view camera and be held in place with rare earth magnets. Since it is a little hard to discern how it works from the photo gallery, I have also made a short video that can be seen here. Please excuse the primitive production values. I will report in again when I have had a chance to test the box in action.
Have been working slowly on a general equipment upgrade. Today I spent about an hour creating a plate holder for my 35mm Pentax that will take the mini-plates I plan to use in getting up to speed with mercury developed daguerreotypes. This is cut from a piece of 0.02 inch polycarbonate. I made it the same width as a piece of 35mm film I had laying around and cut it to a length that made sense for the camera model. Highly engineered blue tape fastenings. Not so pretty, but does the job.
