Copper Plating
bkoenig:
There are some liquid masking products that might make it easier to mask off the rest of the mold.
unfy:
VHT Flame proof is indeed something I was looking at.
Menards has some of the rustoleum 2000f resistant stuff for $5 a rattle can afaik.
That'll all come down later when I get a spare mold heh.
The liquid masking stuff is prolly something i'd definitely look at.
The top built / clothespin rigging stuff is mostly built. Well, all the wood work is done. I was off by a lil bit on a few holes so need to grind down the hanger rods a lil bit so they fit... drill their mounting holes (10 of them, takes a bit per piece of metal, and prolly will require two holes given 1/4" final size).
Need to cut up and crimp ~14 feet of wire for it all too.
Almost done!
edit:
Will be later in the week, back is killing me.
unfy:
Semi-completed.
Might have to move the clothespin hanger things a bit, which will be fine / easy.
Might have to rethink the clothespins things themselves... getting a consistent clamp is kinda rough.
Anyhoo... pictures!
Cups in place, clamps for copper anodes clipped to cup (no copper yet, gotta take a few min to cut it up eventually).
Clothespins hanging on hanger framework. The rainbow wire stuff is for equidistant stuff.
Demonstrating lifting the clothespin hanging stuff. Drawer slides on right can see the lifting whatever.
I've not come up with a clean way of raising / lowering it all yet. In due time.
Clothespins - I like them, I do. Possibly a bit partial since I spent a fair amount of time making them heh.
They don't make for a consistent grab though. While with fiddling they can all be made to be fairly centered, it's just not "rock solid".
edit (2013-03-07) to avoid post bloat:
Didn't see a whole lot at hardware store that looks to be of help to the clothespin <> bar clamping problem.
The |_| shaped aluminum rods in the welding section were too long in the 'legs' for the most part...
Basically, I'll try drilling some holes in the bars and using bolts & wing nuts to attach stuff to see how quickly that goes. Actually, I've got a spare that I drilled some holes in already that I'll toy with. Defeats half the purpose of the clothespins though.
Actually...
There's also something I can't think of what it's called.
It's V shaped. At the vertex/corner of the V is a hole. The legs of the V are held open by a spring. When you squeeze the legs together, the hole at the vertex gets bigger.
It's kind of like a quick release nut thing ?
Hrm.
I'll have to look at other hardware stores as well. I'm pretty sure there's something that can be done with a |_| or even just a shallow L bracket.
edit again:
'quick release nut thing' is actually a drywall anchor thing. i recall the cheap ones not having the screw plate in the picture of this item:

edit yet again:
copper flashing all cut up, got 24 strips for 24 cells total atm. i might have been able to squeeze out one more for the 10 foot by 6 inch roll if this was the original plan.
looking at clothespins and stuff, i just dunno.
unfy:
I think I worked out a solution the clothespin. Prolly over engineering, but whatever.
Gonna take off the top clothespin (that would clamp to the copper tubing originally).
Instead....
Well, currently using 1/8 inch thick by about 3/4 inch wide galvanized chain link strapping as the hanger bar. It's hung vertically (like | , not like -- ).
Anyhoo, picked up some aluminum edging that's L shaped. It's about half an inch long on the short leg and 3/4 inch long on the longer leg.
The thought, as it stands, is to cut the aluminum edging to about 1.5 inches in length... maybe 1.75. Position the edging so that it's like a 7 instead of like an L. This way the lip of the edging rests on top of the hanging bar. Attach the clothespin to the edging on the 'outside' ... like:

Then.... in the power bus bar, have to sets of screws attached about an inch apart for each 'clothespin hanger area' ...

The long face of the L/7 shaped aluminum brackets would be something like:
_________________
| ### |
| ___ ### ___ |
| | | ### | | |
| | | ### | | |
|__| |__###__| |__|
Where # = the clothespin. Basically, two grooves cut along the bottom of the longer lip.
This way, the 7 bracket slides over the power bar and attacked via the two screws with the slots. keeping it parallel to the power bar is done via the lip part of the 7 bracket.
Some wingnuts for each of the two screws for each each of the rigging bar (and matching grooves in 7 bracket). The wingnuts would never need to be fully removed, just loosened a little.
Now.... does it need to be two screws / groove lines ? Prolly not. I'll undoubtedly reduce it to one to save on labor and that I don't think it's really required.
Does it actually need to be wing nutted in place ? i think so - the clothespin is providing the electrical contact so... yeah. Now... if I used a bit of sheet metal (left over copper or something) to act as a leaf contact between the 7 bracket and the power bar... that would prolly make the wingnut unecessary. ... but then you run the risk of the leaf causing the thing to not rest properly on the bar or something.
How to go about doing this ?
I do have a dremel, but I'm thinking just drill holes at the stopping point in the 7 bracket, then use a mini hacksaw with a mini miter cut box to two lines down to the drill hole. Thankfully aluminum is soft.
Now, having learned what I have about myself concerning being completely and utterly unable to drill a hole accurately... this will all have to wait a week or so ... need to pick up a decent drill press.
edit: ps: ph33r mah ascii artz skillz
edit:
Actually, we've got some easily accessible drill presses here at work that look like they should do the trick for this one time use thing.
I will note, why on earth does the boss let folks beat the baby juice out of our tools ? I looked around the wood & metal working area of the shop and got sooooo depressed. Several drill presses that are chewed up / bad belts / etc.... spot welders that haven't been cared for... sliding power miter saws allowed to rust on the slide rails... a metal lathe that just breaks my heart. If I had a place to put it and the ability to carry it out the door I would *so* steal that thing and love it long time.
Hank:
If you ever need some, I have some different types of copper.. like plate, bar, round stock
pretty cool `speriment ya got goin`there unfy...although I must admit them berrys bullets are looking better all the time ;D
