doesnt help that im in no way a machinist and all i know ive gotten from the likes of this old tony and the fabrication series! (and binky of course!) https://www.youtube.com/channel/UCcxlBLmujrjTVSSUkzZ2Jlg https://www.youtube.com/user/featony/videos

sorry, i typo'd that.. meant to type center drill

SUTO would be my choice, mostly because there's a ton of it around and i can usually cadge some for nowt (SuperUniversalTractorOil)

you don't start with a drill bit for a start use a tailstock center first http://www.technologystudent.com/equip1/mlathe4.htm

yes. my sponsor... really bad photoshops:

it seems i've been a bit slow to update this today i spent a LOT of paint and hours (and thinners...) painting the rear of the lorry. looks a lot more presentable now... before after the generator box has been fitted behind the rear wheels and 12v and 240v wiring has been run to the front. so it looks a lot better from the rear now, at least!

my tig has one of those. its a total pain in the arris!

rcd or mcb? and fyi, if you only have a rcd at the source end of a feed to the garage, then you have no overcurrent protection, only earth fault protection, which is dangerous... ignoring that, a decent sized ( but not too big for the conductor sizej RCBO would solve your issue. if you actually have a mcb thats tripping, then changing it for a d type should stop the inrush from tripping it. if its a rcd thats tripping id be more concerned.

for wd40 these work well... https://www.ebay.co.uk/p/Silverline-427579-Sprayer-500-Ml/5031172108?iid=223465390346&chn=ps

no. i wouldnt run less than a 90a alternator with a split charge. but it doesnt rule out a battery issue.

a boat fuel tank, and get welding

used to have these on my bike... http://www.mcdiscount.co.uk/search?q=stebel nautilus compact 12volt&ts=bs&gclid=EAIaIQobChMIg4T3g7DB4QIVBrDtCh1QbQEXEAQYAiABEgKvQfD_BwE made the mot tester shat himself every year

your second questions answers the first. the three amigos are probably caused by the abs sensors.

i wouldnt do it with anything in the pipe. it wont work. at best itll end up brittle. also, i would doubt that that will fail, ive run worse for years. if your worried about it carry a length of hose and some jubilee clips for a emergency repair.

ive had that happen at a couple of dodgy garages to a couple of mates of mine. their face when they called me, i rocked up with a trailer and took the cars a mile down the road, dropped them off and then went back a hour later with a clean pass sheet and a request for a appeal form!
