Linus, for your C8 gasket, some of the light will be blocked due to the height and the 120* LED emission angle. I think the best I could do to correct this is use 1/32” stainless steel dowel pins and also put a heavy chamfer on the square pocket. Let me know what you think:
I made the base extra thick to give me a bit of adjustment room regarding focusing of the led. i.e Gives me some leeway in terms of pulling the emitter out of the reflector some ways, I intend to sand them down to a minimum once I’m happy I’ve found a decent compromise between minimizing the donutyness of the hotspot and maximizing output on these particular reflectors.
I wish I could give you some more exact dimensions to fully take advantage of your great service but this will have to do for now.
The dowels are a cool idea but I’m happy just to go with something standard like these
Test cut a couple of the S2+ xp series rings. It seems the process is more forgiving than I thought it would be so I will probably be able to make these out of black acetal (delrin) rather than nylon. :bigsmile: Acetal machines a lot nicer than nylon and should require less deburring effort. I will test the process with acetal shortly.
I usually sand down the centering ring bottom side and then use superglue to prevent it from rotating when tightening reflector/bezel. I also put a tiny-tiny bit of grease on the top edge/lip of centering ring where reflector will sit so that it could slide more easily when I tighten everything up
Hi fellas. I got into a rather large machining job which I had to prioritize and haven’t had time for anything else. I see the light at the end of the tunnel though and will be able to get back to my fun/hobby projects soon. I will update when I cut some of these these from black acetal.
shrick, I’d recommend using acetal (delrin) if you make them manually. It’s doable but not the easiest project for a novice and it will probably take more effort than it’s worth. As for the tiny end mills, you can use a 1/32” 2fl which shouldn’t give you any trouble in acetal. In the square pocket, machine a relief past the corners in one axis to provide clearance, at least the radius of the cutter in length.
