    2011 Collection Rectangular Extrusion




    Wide Black Body Beam Shot at ~880mA.


    Wide light body

    Cutting


    Next use some 1/4 inch by 3/4 flat strip.

    Rip it to the inside height of the light body to form you slug. Then cross cut to fit width.

    Used bench grinder to shape reginas to fit.

    On off Switch

    Using Tamiya mini connectors with heat shrink covers.

    Driver for both lights

    Smaller orange light is made from
    Aluminum Rectangular Tubing .75" X 1.5" X .062
    Sorry no link on this extrusion. Found it on ebay about a year ago and haven't needed any since.



    Small Orange light with shortened Regina reflectors beam shot ~880 mA.




    Using modified reginas.

    Cut to fit internal of extrusion.
    Slug done same way as above. Trial and error to get tight fit from aluminum bar stock.


    Fins can be "dado" cut.


    This is done with multiple soft steel saw blades spaced with grinding wheel/cut off discs.

    The disks come in various widths so you can make whatever spacing you want/need.



    Just gives a little better uniformity and is faster since 3 beds are cut at a time.

    I like them. Good thing is if any body pesters me about selling lights I can just tell them to buy the Amoeba, they get the same great beam and good customer service.

    Neat process. Bright too. Do you do the ano yourself?

    Very nice OD! On the black light with the edges cut off the Reginas, do you notice any weird changes in the beam quality over a stock Regina?

    Do the ano at home. It's a hobby. As it making the lights.


    No major artifacts with the wide body modification. I was worried about it as well, but its very smooth beam and throws a little better than the shortened regina.

    Flip side to that is the shorter regina gives better fill, so it is actually the better riding light for me.

    Cool. I have a couple that I have milled a few mm off the edge to fit my next microlight. I have not tested them and was a bit worried that it might be a problem.

    The Amoeba is very nice, but I like the fins and finish of yours, odtexas. Nice use of the dado cutters.
