Vacuum former has failed its PAT test

[amcewen]

The insulation resistance test has failed. It should be >20Mohms but is currently 0.33Mohms.

Maybe we just need to replace some of the wiring?

Heater wiring done already (mostly) so this might be fan wiring, or panel switches.

This was looked at again today by @Sean-anotherone and a potential user (Chris) who concluded that low insulation resistance of the ceramic heater elements is the culprit. While it might be possible to “bake out” the heaters with some use, a better solution might be to remount the heater assembly using ceramic stand-off’s, so it is isolated from the chassis. Chris has offered to investigate this option.

Have found a source of ceramic feed throughs used in pottery kilns that should fix this - they insulate the pin / bolt from the panel it goes thorugh. I have ordered 5 medium size - see https://www.cromartiehobbycraft.co.uk/Catalogue/Ceramic-Kilns-Electric-Kilns-Pottery-Kilns/Kiln-Spares-Kiln-Elements/Porcelain-Insulators/Porcelain-Insulators-Complete-Medium-22mm-dia-6mm-pin-PORCELAINSCOMPLETE-MEDIUM - the two ceramic parts separate and form a sleeve to insulate the panel from the metal pin. I'll bring them in the first Thursday after they arrive.

Also hopefully collect the sample plastic tray and tool / which I think I left my the sample 3D printed objects near the door, or maybe on a random desk - hope they are still there as they are important to me :-) Best wishes, Chris

Feed throughs have arrived - allbeing well will see you on Thursday night and bring them then.

Excellent. If you can bring the receipt, or email it to hello@doesliverpool.com, we can sort out reimbursing you for it.

And @JackiePease stashed your samples on @DoESsean's desk (IIRC)
