Knighty, I've tried messaging you but nothing is showing up as "sent" at my end, are they getting to you?

I've got it, just in time too, I've been trying to pass them on for a while and was about to give up and was going scrap them tomorrow!
(having a bit of a clear out)

I'll hold them for you, just let me know when you want them :-)

No need to tap if the cell posts are already threaded. Copper is so soft if you were feeling courageous you could probably run the tap in with a drill without fear of breaking the tap.
Use a cable ampacity chart to spec to spec the bar CSA to max load + 20%.

Heatshrink the bar between bolt holes to insulate any extraneous metal. Fuse the main positive with an ANL <1m from the main terminal.

You can use thicker aluminium to get the same conductivity values which is usually cheaper and slightly more corrosion resistant.

Marine grade would be fully insulated with shrink and terminal caps, tinned bar, glue lined colour coded shrink tinned lugs and tinned hardware. The less reactive (oxidising, anodizing metals in the mix the better). Avoid steel & zinc (bolts and washers) wherever possible.
 
Cheep and cheerful solutions involve servicing with a wire wheel every once in a while.

400(+) - 300 scrap value = couple of hundred...What's the problem?
Put them in a box on the wall with a big T on it and they'll be worth three times that.  Knighty practically paid you!  ralph

I know that, but getting the point across has been "delicate".

I blame it on her hormones, silly girl gets pregnant far too easily!

I can send you a photo of what my other half has to put up with if it helps the situation Stevie? I've way more expensive taste in barely working gear... Roll Eyes
My argument is yes dear it's expensive lecky, but it's clean and a cheaper investment than planning permission!

Of course I used to spend ~ 1.20 a kWh for alternator lecky. So by my standards I'm saving bucketloads.

hi, sorry I disappeared there

replied to PM but thought I better reply here too after we missed each other before

I've got a chest infection (bit susceptible to them after I damaged my left lung in a fall last year)

and then I coughed so much / so hard I strained the muscles in my back / right side :-(

I'll sort them out early next week - which day works best for delivery for you ? - or if we wait to organise it next week you can give me an exact date and I'll get it sorted this end :-)

No worries, i'm well aware of how badly a bad back can slow you down.

Could you get them to me for next friday? The 13th, what could go wrong...? If not, any day apart from thursdays are good for me (better half does night shifts on wednesday/thursday night, and needs her kip)
