    Heating a garage workshop

    It shouldn't be using max power 24/7 though. I set the thermostat on mine between 12 and 15C (the higher end if I know I'm going to do stuff in the garage with chemicals that like a bit more temperature). In a well insulated space it won't be running for long periods when the room is up to...

    Heating a garage workshop

    Assuming it's well insulated, an electric oil filled radiator (e.g. TRD41025 Dragon 4 Oil filled radiator | Delonghi International) will keep the temperature to a sensible level (e.g. 13C) even through the winter. They're pretty safe, and don't create extra moisture. I also use a dehumidifier...

    New chuck question

    Agreed about needing to turn a backplate, but unless a Pratt Burnerd chuck looks like trash they'll generally be pretty good (in my admittedly limited experience). This document (http://www.rotagriponline.com/datasheets/Pratt/PrattChuckSpares.pdf) is hugely useful for decoding "what" a PB chuck...

    New chuck question

    If you use a lot of standard size rods then a collet chuck might be better, as they're much more suited to removing and remounting stock (without introducing runout). Even a decent 3 jaw will give (some) problems when you remove and remount stock.

    Checking a lathe (runout, ways etc.)?

    To be honest; it felt like an ideal excuse to make a ball turning attachment for the lathe, and make some up from HDPE rod. That, or find a used set of snooker balls :)

    The MA thread - AKA Everyday Fan Vault Construction for Beginners.

    Today I learned "conoid" and "spandrel" :)

    Checking a lathe (runout, ways etc.)?

    That looks great. There is a Harrison 140 also available locally. Looks cosmetically good from the photos, but it is £2000. As for the Chippie; certainly I'd want to be talking the guy down to (or under) the £1000 mark. For the capacities though; aren't the Chipmaster 5x20 and the Harrison 140...

    Checking a lathe (runout, ways etc.)?

    As far as I understand, the Chipmaster has two "speeds"; in the sense that the variator has a roughly 9:1 range, with the low gear range (35-300rpm) powering the spindle via gears, and the high range (320-3000rpm) being belt driven. I'm told (but haven't confirmed) that 6 pole induction motor...

    Checking a lathe (runout, ways etc.)?

    Got it - the use of a tube makes sense now. Thanks. As a childhood user of Lego I consider myself to be an expert on gearing and torque ;) Absolutely understood on the VFD vs variator torque issue. From what I've seen, people who pick up a Chippie tend to replace the variator (even if it's a...

    Any (post 2008) Economists in the house? - Inflation.

    You can't trust the octopus guys; they're really slippery. That said, I hear the rhinos are a bit horny. Still, I'd rate either of them as having a better chance of winning a General Election than the Labour party Jacob would like to see.

    Any (post 2008) Economists in the house? - Inflation.

    Which countries? PR has always struck me as the most "fair" system; if 2.8% of the electorate favour the octopus nostril party*, then 2.8% of the seats in your house of parliament will go to the nostril boys. However, I thought that in practice it tends to rarely return a majority government...

    Checking a lathe (runout, ways etc.)?

    The lathes.co.uk website is both very useful, and very frustrating (as often I just want tables of dimensions and model numbers). I see it mentions that "later" models were hardened, but as far as I can see there's no info as to when that happened. The one I'm looking at has a serial number that...

    Checking a lathe (runout, ways etc.)?

    Very useful info - thanks. I can guarantee that there's nothing wrong with the variator; as there is no variator 😁. It currently has a 3 phase motor control; though I don't know if it's running the original motor. That doesn't worry me particularly, as I get the gist that many people swap out...

    Checking a lathe (runout, ways etc.)?

    That's kinda what I'm hoping; given that it looks cosmetically rough but the owner seems quite happy that I want to clock it to check the bearings. I'm going to see it this weekend, so I guess if he knows it's a dog then he might have been evasive about me saying that I want to check it over...

    Any (post 2008) Economists in the house? - Inflation.

    I'm not sure I'd consider the Grauniad (sic) as a well respect paper. I mean, even as as stinkin' lefty on many issues I find it a bit over the top ;)

    Any (post 2008) Economists in the house? - Inflation.

    I guess that's always the problem with tax laws; simple and people will (rightly) point out that there are exceptions who are unfairly hit due to their specific circumstances. Complex and you introduce loopholes that are exploited by those with the resources to do so. That said, I'm pretty...

    Any (post 2008) Economists in the house? - Inflation.

    Personally, I'm not after harsh taxation; just preventing the massive tax avoidance that allows large profits to be made with almost zero tax payment. Agreed that it'd "take only one haven country" to cause problems, but it would surely be possible for a nation to introduce rules to try to bar...

    Any (post 2008) Economists in the house? - Inflation.

    That's the root of the problem; if there were no tax havens available (such that the ultra wealthy couldn't leave to avoid taxes) then that issue would solve itself. I'm not talking about "punishing" high earners; just ensuring that those individuals and companies who are raking in huge sums of...

    Any (post 2008) Economists in the house? - Inflation.

    Funnily enough I was having a similar conversation with some very pro-Labour (anti-Starmer) friends recently. My suggestion was that Labour need a Boris; get an entertaining clown in charge, amuse the people, get the votes, then (in theory, probably not in reality) put in place policies to...

    Checking a lathe (runout, ways etc.)?

    Thanks. I have my eye on a Colchester Chipmaster 5x20. Well, actually two - one looking pretty sorry for itself cosmetically, but obviously much cheaper. I quite enjoy restoring a "lost dog", but regrinding worn ways and replacing Gamet bearings is something out of my skill (or wallet) zone.
