Ordered three cells from RS components. https://uk.rs-online.com/web/p/speciality-size-rechargeable-batteries/8801551/ Not perhaps the cheapest but I am suspicious of the eBay stuff and these cheap on-line sellers seem too full of gimmicks for my liking. I need a reliable long term result, not a flash in the pan.

Have you seen these? This is a three cell pack but also come in 2 and 4 cells enclosures. https://www.ebay.co.uk/itm/Battery-Holder-Box-Case-DIY-for-battery-packs-1x-2x-3x-4x-18650-cells-UK-FreeP-P/182891735071?hash=item2a9532681f:m:mooQhmh4rS23BLh2OK38M1Q Means you can use standard untagged cells and you can swap cells in/out for your battery charging or replacement needs. This makes for a good external battery. You would need to identify a way to lock the cells into the EN-EL4 for internal battery recelling. In this case it is probably best to use tagged cells.

Please can anybody suggest a source for small quantities of copper foil, about 0.15mm thick (or thin!) this equates to 0.005 of an inch (five thou) or 36 Imperial wire gauge. I don't need much, an A5 sheet would probably last me for years! I have searched and searched but it needs to be a UK supplier who is happy to supply small quantities. Possibly some specialised craft or model shop? It's for the tag connections, the tags provided on the ends of the cells aren't long enough nor in the right places radially at the battery ends. Soldering wire connections of sufficient capacity is bulky in the tight confines of the battery housing, there isn't room. The tags are nickel plated steel and are 0.15mm thick by 5mm wide. I don't want to go much thicker to retain flexibility for assembly. Copper will have less electrical resistance than nickel plated steel and be more ductile and flexible. It's also easier to work, can be cut with sharp scissors, craft knife, etc, and very easy to solder. I did consider brass but it's not so flexible and it cracks when repeatedly bent.

Brass or copper will work. Craft store is the place to go or check in B&Q as I saw some there some time ago. They do brass rod (actually rectangular section which would work). Remember with copper and brass you can heat it and beat it to make it easier to work with.

Scrounging round a scrap yard I found a piece of clean 0.5mm thick copper, will anneal it tomorrow and see what it's like but I think it's a bit thick. It's OK for some parts but not flexible enough for the battery to PCB connection which has to be like a hinge.

How is the re-celling activity going? I have six new ordinary 18650 cells. I might have a go building a unit if I find any of my batteries die.

Have stalled slightly, cars and life getting in the way a bit. I have glued the cells together with Gorilla glue so they are 'as one' I have found some thin copper, 7 thou I think. They are sat waiting for the soldering iron... I am also creating a panoramic head for 360/180º spherical panoramas. I have got my lathe up and running at last. This is an 'artists' impression of the pano head, turned from solid aluminium.    I have made the curved bit and am working on the revolving hub at the moment. Need to incorporate some sort of click locations to the vertical (pan) axis. Have made the main hub parts, tomorrow I make the steel shaft for it to rotate on.

A couple of drawings, the intended lens being my 16mm f2.8 fisheye. The red marks denote the field of view of the lens at horizontal.   The centre axis of the partial ring is at the nodal axis, both vertical and horizontal, the pan axis is taken care of by the length of the arm connecting the hub and the curved dovetail ring. That will be fixed for each camera, two arms, one longer for the D3 the other shorter for the D200 and D300.

What software you using for your CAD.
