That makes sense! I was thinking it was the name of something when I read it. Where could I find something like that? I’ve sourced pretty much everything else! And any preference on the type of grease?
I’m always scavenging bits & pieces of stuff that I think I might find useful when I come across them, no idea where that ring came from.
Just try to find a piece of tube the correct diameter or order a small sample piece etc.
I use light white lithium grease.
Moly is a bugger to get rid of, silicone grease doesn’t work too well.
Also, you’re better using white or preferably transparent tape.
Once you’ve used the UV light on one side you can flip the mould over and blast the other, useful if you make a thick mix as sometimes the UV light doesn’t penetrate all the way through.
I have everything sourced and ready to go but for the life of me, I can’t seem to get the drilling to come out right manually. I’m tired of ruining boards! I can always wait a few months til I visit my folks and use the old mans drill press. But I was thinking maybe I could order a custom mcpcb from oshpark. So i downloaded some pcb making software but there doesn’t seem to be a simple way to just tell it to put holes in places. Does anybody have any experience with that kinda stuff that could guide me to do that? Is it even possible?
You mean drilling the template?
Drill smaller holes than needed and hand file them to the right size/ positions with small diamond files, that’s what I did anyway.
Trying to drill the holes manually first time will lead to lots of… experience
Here’s one that has slots for tritium vials (not shown in the preview, it’s lying on its top side).
Though it might make more sense to print a mold from this so you can cast them in silicone + glo.
No idea what filament doesn’t stick to silicone, you might have to experiment with that.
First I tried ExpressPCB. Played with it for about ten minutes and gave up. Next I tried Design Spark but it had an error installing, so on to the next. I think I’ve got it figured out with Fritzing.
