I cant remember but definately not d**k smiths or jaycar, i will have to search through some old records as i have not purchased any for quite a few years - i brought 50 or so 10 years ago and they last quite a while - it was from a company in victoria or nsw i think

i used to service/repair complex machinery in the printing industry and they were brilliant for cleaning contactor and switch contacts - it would remove all the carbon and polish them back to brand new without damaging the silver coating of the contact face - its essential to have clean resistance free contacts when using on low voltage applications and use a quality lubrication grease designed for electrical switches on reassembly

its a strip of grey double sided velcro type material 10mm wide by approx 170mm long and about 3mm thick

No worries, i'll do some checking.

With those tips, I'll have to peruse a few things in the shed. I was going to try shaping some knitting needles , they are a hard plastic , might do the job as opposed to nails, worth a try. The springs would need to be in better condition.

Might purchase two Bic retractable pens and use those springs and see how it goes.
