The Paraboilc Mirror;

This is a excelent calulator for parabolic formulas.

I was able to create the profile and the focus point of my desired Parabolic Mirror.

I then cut 20 of these poly curves on my cnc cutter. The 20 profiles were then assembled into this block and held fast by a 3/8 x 5 " bolt.

I Cut a peice of 6" copper pipe and hammered it over the form this took a long tiime and I used my bender, clamps and sledge hammer to form the copper very close to the profile.

The curve was smoothed and 80 grit sand paper was attached to the block.

The sanding block was clamped into a bench vice. The first sanding took only 7 hours. Dedication to a single task. I used water and oil to assist the honing. Next 240 grit 4 hours of sanding.Then 600 grit. 4 hours. Finally 1200 grit and a polishing paste 12 hours.

The mirror will be nickel plated then gold for ~ 90% reflective surface.

Brass end plates were then machined on the cnc, and the yag mount hole were cut.

This is one of the led modules I am using.

I have modified it to remove the ears and the corner tabs.

I will be using the connection inside the module.

Here the 9 modules are mounted on the heatsink. I used 1" stainless No. 4X40 the extra length will assist in the cooling. This whole unit will sit in an enclosure that will be water cooled.

I have place the mirror on the top of the led bank to show the alignment.
