    Two separate contactors for fwd/rev. Then the main contactor set up as an NVR. I think what I thought was a separate winding on the main contactor is just a secondary little coil to energise the pilot light "P/L". Then the fwd and reverse contactors have a small set of NC auxiliary contacts. They're just used to break the feed to the other contactors coil. Just going to chuck in 3 modern contactors I think, retain the original overload (unless I can find another). The existing coils are all 415VAC. I'll either use 230 or 48VAC coils and a small control trannie if necessary. The fwd/rev is a proper (you can see it sloshing about) mercury switch. Keeps the grey matter ticking over. No star / delta on this..... It's being run off a dodgy phase converter.

    The hold on contact is on 1 & 2 isn't it on that RH contactor? Drops out if the o'load trips or you press stop. Or a power failure.

    Just interested more than anything. They're big lumps too. Fully strippable. 415V coils. Burnt to a crisp. Can't access the motor terminal box without moving the lathe. Measured nom 6 Ohm between each phase at the overload. IR was circa 2M Ohm each phase to earth. In a damp old shed!

    Playing with an old lathe here and the main contactor cum NVR switch has burnt out. A weird thing I've never seen is the contactor coil has two windings? I've seen motor brake coils with two windings where one winding excites the brake then ms later it gets the full wallop to release but never seen a contactor like it. Contactors are pre 1948 when British Klockner were sold.
  5. Fairy Liquid is alkaline isn't it? Try vinegar in water even over a small area, just as a test.
  6. Tell me about it! Went to bed, cat scratched at door waking me up. Got up and let him in. Cat sat on the bedside table, I went back to sleep. Cat trod on my head waking me up. Went back to sleep. Awoken again by the cat projectile vomitting across the duvet, I woke up, shooed it out, changed the bedding. Went back to sleep. SWMBO came to bed waking me up. Went back to sleep. No.1 son woke me up as he came up the stairs to his bedroom after an all night gaming session. Genuine offer to swap one wife, son (c/w degree) and a vomitting tabby for your ASHP. I'll flog it on and buy insulation. ?
  7. Just bought the twin 5.0Ah Makita kit with the 10% off code.
  8. That probably means Jack Schidtt unless they want to put it in writing.
  9. A good builder could recreate the "inny outy" effect of your original render. I seem to recall your new extension matching pretty well and that you deliberately asked for it not be all clinical and smooth? Plenty of low energy builds on here with thick walls (due to insulation) where the resulting house looks very traditional. Tbh a bad builder might actually get closer to the orginal without trying! ?
  10. I followed 2, riding abreast, for miles along a very narrow country lane. At a junction I wound the window down and said "Excuse me mate but I'm pretty sure the Highway Code says you should have given way. Got a right mouthful back.
  11. Been bolting steel up for 40 years. Only ever use a nyloc or full nut & spring washer on assemblies. Usually specified by someone a lot cleverer than me anyway. Very occasionally a castle nut and split pin and even rarer a tri pointed washer on HSFG (high strength friction grip) stuff. I'd have to go way back to think of the last time I used Aerotight or Binx nuts.
  12. Very few are courteous tbh. Older ones are better. Younger types tend to glance over their shoulders then go ar$e up, head down for 4 miles whilst ignorong every opportunity to pull over/slow down/let you pass, whilst creating a tailback of traffic behind them.
  13. Worms are good for the soil and ecosystem etc. I'd be loathe to "kill" them deliberately I'd get 5L of white vinegar, dilute it and spray the patio with it. Worms don't like acidic soils particularly. There are nuclear options but I'm not going to recommend them.
  14. What I say to the kids when I see a cyclist holding everything up? "Ah the C word!"
  15. Trying to explain to my mate why cladding his workshop in laminate flooring he's planning to get from Freecycle etc is not a good idea. For example: - Some have MDF cores. Moisture will get at it from the back. - Joint profile is completely wrong for shedding water. Multiple entry points for rain to get in. - Even a blockboard substrate probably isn't made suitable for external use. Help me out with a sentence or two why it's a really bad idea! I saw what happened when the FiL made a shed by cladding an old greenhouse frame in MDF and covering it in roofing felt. Eventually the MDF became so sodden, the weight of the felt alone broke the MDF apart. ?
  16. Obviously the full nut goes on first. The half nut is there just so the subsequent decorative nut caps don't sit properly! ?
  17. How about some reassuringly expensive Aerotight nuts,?
  18. I'll raise you full nut and a half nut! ?
  19. Best get the grinder ready if you're fitting lots of M16 A2 stainless.
  20. You could dispense with the full nut and split washer and use a nyloc nut instead. Always, always, always lube the nut / bolt interface with copper or aluminium based anti seize compound when using nyloc nuts.
  21. You could retain the character with external wall insulation (ewi). You'd still be pi$$ing into the wind because of your floor situation so even more expense to dig those up and take the ewi down below the footings. Even then you'll have cold bridges up through the internal walls. Let's not even start on the roof! You'd likely need to change that to get enough overhang to cover the ewi. Do all that and you'll still need to address the air tightness. The low energy houses on here and our traditional builds are a million miles apart. One of the passive type house builds on here took less energy to heat for 24hrs than it takes to boil a kettle...like 2/3 less. Just for a minute take that in. I wholeheartedly agree with the sentiments of Insulate Britain btw. I'm quite happy if they want to come and glue themselves to my outside walls.
  22. You basically have a traditional, shitty old big house with FA insulation, holes galore, leaky as a colander with multiple heat loss paths. JUST LIKE ME! You either knock down and rebuild or try and bring the insulation spec up. You can't do either without ? None of the above will deter installers selling you a pup. The government handing the grants out don't give a sh!t as they've ticked a box that your house has been "improved", "made green" and is helping save the planet. I would never have an ASAP as my building fabric just isn't right for it. If I was well insulated etc I would.
  23. It's astounding / time is fleeting / madness takes its toll ...
