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.
Well, in the course of making a backup of TheDaguerreotypist this morning I wiped out some crucial WordPress files and brought down the whole site. Thank goodness for ISP’s that make periodic backups without being asked! After the restore I had everything except the most recent post about making a pair of buffing paddles. The pictures of the process are here.
The goal was to make a simple paddle that could be easily replicated in larger sizes, and had a system for holding on the covering cloth in a way that kept tension on the covering and also allowed the cover to be easily changed. The base material is a 1/2″ softwood board with a layer of felt glued to it. It is covered with Ultrasuede. The Ultrasuede has sewn in pockets to hold some pieces of 1/8″ steel rod that in turn are the anchors for a set of four steel springs. I also tried a string and spring version and a rubber band version, neither one of which worked very well.
The dimensions are not critical, you only need to make sure there is enough distance between the two steel rods so that the springs are under some tension. The free ends just tuck under the springs. The whole shebang just sits on the workbench and a plate held with a suction tool is rubbed back and forth along the top. It doesn’t move around much when polishing sixth plates. It might need some kind of hold-down in bigger sizes.
We will see how well it holds up in use. Now off to make a new ground glass for my camera to replace the one that fell out on my foot. This was not my best day ever.
After a couple of false starts I have finally succeeded in completing my gilding stand design. This unit is made entirely from off the shelf hardware and will adjust to plate sizes from ninth plate to 8″x10″. The gallery contains pictures that show the construction details. The construction requires very little machining – the aluminum bar stock that makes up the base was cut to 1 ft. lengths on a table saw and drilled to accommodate the 1/4″-20 threaded rod that makes up the legs of the stand. The turnbuckle bodies were drilled and tapped to accommodate the 6-32 threaded rod that make the plate supports. Cap nuts, wing nuts and star washers are the remaining ingredients. Read more »
