My Aluminizing System
Well there it is, not particularly pretty, but it works and its portable J Below is a list of possibly interesting aspects of my system.
Here’s a short list of things I need to do still.
To date, I’ve ran a bunch of test pieces through, a 5” mirror, and a 10” mirror, all with good results, and only one catastrophe. The bad part is, the one catastrophe over shadows all the good results up till now L What happened was as I heated the tungsten filament, a blob of aluminum fell off the heater, and landed on the mirror surface. At first I didn’t think much of it, as it looked just like a what happens when a blob of plumbing solder lands on a cold surface. Unfortunately the aluminum was MUCH to hot for the Pyrex mirror to handle, and a pit about a ¼” in diameter and 0.015” deep formed. The worse part is, the blob of aluminum didn’t land in the center of the mirror, but about 3 inches from the edge (still not certain how it landed so far from the center.) Today I learned a valuable lesson, either pre-melt the aluminum in an empty chamber OR install a shutter to prevent this from happening! Going from a finished mirror back to 80 grit is not something I ever want to have happen again!
Here’s a picture of a recent test item to at least show the thing works J
That’s it for the moment, still bummed about damaging a mirror, but I did learn a lesson, worse part is I had been warned about just such a thing happening! Sigh…
Anyway, check out some of the sub links on the left if you are interested in seeing just exactly how I got to this point.
