After having a reasonably functioning FW I started working on the light body.
Some time ago I have found a piece of aluminum profile almost identical in shape to my first handmade lamp it is from an old parking lot gate so I kept it, knowing it can use me for building a light.
I have tried to cut it with a hand saw and a jig saw but all my tries were not pedicular at least in one direction :(
some kind of table saw or miter saw is probably the correct tool for it but since I don't have one, so I had to improvise using my skill saw and a guide, trying to make it safe as possible
I am planning to keep the central partition in order to add strength. It will also allow me to add 2 separate heatsinks: one closer to the front window for the bare LED and one with more space for the optical lens.
I have a new 2 degrees very tight spot lens ant it is pretty big and requires a lot of space.
