Hey Hypnos1,
How do i get the black metal shields off of the c3gs'?
Right then mab, here we go...don't want to sound like Mother, but please take VERY careful note of the pointers...would hate for anything to go amiss with these little treasures:
1. The bottom outer rim of the canister is folded (fairly soft metal) over the metal protective tube base. So, using a pair of small (preferably) pliers, gradually and gently prise that rim away, as per photo #1 - you don't need to pull it
too far away :
At this point you can see clearly the different-shaped cut-out for orientating the base to tube (church window as opposed to round)...
2. You may well have to gently 'wiggle' the metal base and/or adjust the prised rim to lift out said base.
NOTE : there are 3 washers - over pins 2,5, and7 (not exactly sure why...perhaps something to do with heat transference?). They might possibly come adrift as you remove the base...
The protruding "locator" on the side of the central metal cylinder corresponds to the mid-point between pins 1 and 8.
This mid-point is marked on the glass bottom by a
tiny pimple, located at the 6 o'clock position in photo #2 - the pins running clockwise from #1(to the left of mid-point as you look from below)...
Note the 'church window' of the metal base sits over pin #6 - (I'm sure 2, seated either side of the 'mid-point' would have been
much less confusing lol!).
3. You now have 2 options, of course...#1: pop it straight into the adapter, which would need EXTREME care - you would have to clearly mark that mid-point on the side of the tube, to ensure correct location with the indent on the adapter. Also, that protruding glass tube seal looks rather vulnerable - probably no trouble when pushing the tube
in (still with care..), but potentially a problem if having to waggle hard to pull it
out!
Option 2 is much safer, of course : glue the base back on...as there's a small gap between metal and the glass, something like a 2-part rapid-setting clear resin/adhesive applied to the inside rim of the metal base should do the trick...or whatever your preference is, mab. And don't forget those 3 washers!
Just make DOUBLY sure of the positioning - church window to same, and protruding metal 'locator' to glass 'pimple' - and all will be well...
If ever you should have a problem with a base - eg (not that it
would happen, I'm sure!) : the base comes unstuck, and then gets damaged prising it out of the adapter (aren't I a cheerful chappie?!) - have no fear, I've a couple of spare ones you could have.
Hopefully, mab, this is all the info you'll need. So I shall wish you all the best with the project - it certainly is worth the (minimal) effort to reveal the beauty hidden within!
Any problems/questions, just post or PM me...
Cheers...and remember the 30-50hrs burn-in needed!!
