c6 brass ring help?

jcranmer · May 30, 2013

I hate to ask, but does anyone have a very detailed tutorial with good quality pictures? I just managed to mangle another brass ring. It can't be this hard to get a 17mm battery contact board in a c6.

Which way does the ring go? Shelf towards the inside of the pill or outside? If it goes to the inside do you normally press the ring before you solder the battery contact boards negative to it or do you solder and then press it?

Here is what I do.

1. Get your 17mm driver board or contact board ready. File the pieces sticking out on the edge until flush with the sides of the rest of the driver/contact board.

2. Press the driver board into the brass ring. One side has an indentation; this is where the driver goes. You want the components in the driver facing the side WITHOUT the indentation.

3. Once the board has been pressed into the brass ring, solder leads to your driver if you haven't already and then press the ring/board assembly into the driver pill. You want the components inside the pill and the contact point facing outwards. Make sure the leads go through the holes as the assembly is very hard to remove once pressed.

Any questions?

That sounds just like what I have been doing. I just can't seem to get the brass ring & contact board pressed into the pill. I actually shattered the last brass ring trying to press it in with a vice.

Maybe I have a pill that's a little out of spec. Time to try another one.

Oh and if anyone has some spare brass rings, I could use some.

I actually mangled one recently or I would have an extra one. I will be making a C6 build here soon, and I will make a video of that process.

survival laser sells the rings and pill cheap

That would be great. I basically understand everything that needs to be done, but I guess the brass ring isn't easy as it seems. (Well it could also be I really don't have much use of my right hand too. )

That's actually the route I'm going. Picked up a battery board at the same time. Maybe I'll get it this time. Now I have to wait till Friday for my replacement WESD51 that also died on me today.

You need two flat surfaces pushing together. If you only push on one side the ring get mangled. Or just push very gentle around the ring with a plier. Do that in small steps.

I mount a small diameter (approx. 3/8") aluminum rod in a drill press chuck, and use it to press on the center of the pill. The brass ring goes in easily. For drilled pills, I place a 5/16" square lathe tool across the center of the pill and press on that.

:beer: May have to give that a try. Hadn't even considered the "press" part of my drill press. :thanks:

Try it you'll like it.

My preferred method is actually the opposite = first press the bare ring into the aluminium pill. Then press whatever boards you need into it.

Sounds dumb but actually once the ring is in place, it cannot be shattered or warped. Who would've thought huh?

Obviously just be careful to press the narrowed side first, and you're good to go.

Extra bonus, hammering the board/driver out normally doesn't remove the ring, it stays in place.

That's why I just make my heatsink's board sockets appropriate width right away. That ring is best pressed into aluminium and forgotten. Moment it's not in the pill, you can lose it or destroy it.

The problem with pressing the brass ring into the pill first is that it makes it more difficult to solder the driver to the ring, due to the "heat sinking" effect of the aluminum (for me anyway).

Eudaimonium · Jun 1, 2013

I never soldered anything on the brass ring.

My favorite method of getting a case connection is the diode's case.
Second favorite is putting some solder on a wire, and pinching it in between the contact board and ring/heatsink/whatever.

IsaacT · Jun 1, 2013

The hard part with using Diode Case is that I believe they are talking about the C6's here, and they are anodized so there isn't a connection up at the head.

Eudaimonium · Jun 1, 2013

I make my C6 heatsinks just long enough to hit the aluminium pill.

:na:

So there's that.

You could use the third case pin of the diode for the connection. But that would make thinks was too complicated. The heatsink must be long enough to touch the pill.

Anyway the best is just solder the brass ring to the driver and then press the whole into the pill. That is the way the C6 pill is designed.
If you want to take out the driver/ring in the future then make the solder connection small as possible. You can push the driver out of the pill from the other side though the small holes with a screwdriver or a small rod.
The brass ring can also be taken out with a small screwdriver by wiggling the small gap in the inside between the ring and the pill.

I have never mangled any brass ring this way and I have build many C6 lasers.
