Thread: Garmin sat nav

The battery on my Garmin isn’t very good either. I bought one of their chargers to use indoors from time to time.

I would have liked it in my car but it was an additional £600. I’ve got a fairly decent iPhone though so I can use that if needed.

The OP was clearly about insert tooling as per the picture so I don’t know why it’s changed to HSS? thinking

Does it matter ?

… The thread is about Tool post height

MichaelG.

No, but is was originally about insert tooling.

Humans have poor memories. The arguments made against modern and future technologies are very similar to those made against the very ones we use today. Many people don’t like change and make illogical arguments about things they don’t fully understand. Some of them are even second guessing technologies yet to be developed. We really don’t know how this is all going to play out but the decision has been made to get rid of out dated technology that had a limited timescale anyway. Whether EV’s remain long term or are replaced with something else shouldn’t be of any great concern to anyone on here as they won’t be around anyway. There are many myths about EV’s already and making up more just because some folks have no imagination to tackle the problems isn’t fooling anyone. And it’s certainly not fooling those in power - at the moment.

There seems to be lots of research into energy storage so I wonder if the ultimate goal is to go almost fully renewable at some point? I did read an article some time ago that suggested we could as a species go virtually fully solar if suitably interconnected. They even suggested the acreage of panels required and it wasn’t as large as you might expect.

I'd want the option of having a long bar poking out of the rear of the headstock.

Rod

It depends what you mean by “long”. I’ve had a couple of feet of material sticking out the back of my hobby lathe without issue. Some thinner stuff has needed extra support though. Speed of course is another issue.

I found at the model engineering shows all the bigger stuff was cheaper. I suppose because many model engineers have modest size machines. I’ve paid as little as six or seven pounds for a tool holder. Having machined a Sandvik tool holder for a friend I was confident of being able to machine them when needed.

Thread: Insert Tip radius?
09/07/2021 16:24:47

Thanks for your thoughts folks, most helpful.

09/07/2021 11:23:46

I’m just wondering what tip radius most of you find the most useful for carbide inserts? I’ve just bought some .4’s so I can get a reasonably tight shoulder and the finish was good. I’m just wondering if I should get some .8 as well? If I need a really tight shoulder I use HSS in a tangential tool but I like using inserts for aluminium alloy.

Does all this beg the question, why use bigger tooling than that which will fit?

regards Martin

Edited By Martin Kyte on 09/07/2021 08:04:19

The smallest tool holder for some inserts is 16mm so no choice. The TNMG is a case in point. I’ve just got some polished inserts for aluminium at a very good price and they work really well. The tool holders are cheap on the auction site.

08/07/2021 23:17:07

I think my little 8 1/2” x 14” is meant to take 10 or maybe 12mm tooling? I bought a 16mm TNMG holder and trimmed a couple of mm off the bottom and it works well. The holder is quite tough but it wasn’t too much trouble to trim it down with a carbide mill.

Its nothing to do with how much you tighten a QCTP ! The problem is with the amount of overhang some have. The tool needs to be within the footprint of the cross slide for maximum rigidity.

I agree. It’s also not difficult to understand if you compare some of them. I guess if you’ve spent hundreds of pounds on tool holders you’re less likely to find fault though.

Height adjustment is often mentioned as some kind of insurmountable advantage. I use a Tangential tool which has built in height adjustment. I also use insert tooling with tool holders that have been machined to the correct height for my four way or I’ve permanently bonded shims to the bottom.
It seems nonsensical to have height adjustment when using inserts, perhaps that why it’s not used on CNC machines. Of course, if you use lots of hand ground tooling and are a professional then I can sort of see the argument. As for speed, it only takes me a couple of seconds to change tools in my four way.

I’ve just checked the specs for my VMC and it’s apparently 415kg and it’s fine in my shed. My lathe sits on a wooden bench and I’m sure weighs something similar to an ML7. The foundations are concrete, then there are 50mm bearers with insulation between and then topped with 19mm boards. I then laid 9mm ply on top that which was painted to give an easy to clean surface.

I’m actually just as interested in the decline in Diesel cars as we really need to get them off our streets as soon as possible. Luckily the message is getting across. Hopefully the complete ban on using Diesel cars can be brought forward by ten or fifteen years.

I’ve got a VMC simply screwed down to my wooden shed floor and haven’t experienced any problems with it so far.

If I need to chop a lump from a big bar I drill it then use a hacksaw. I have seen folks drill at 90° as well before sawing.
I joined the Belt Grinder group on FB, some nice looking machines on there.

Sorry Bazyle but that idea is just not tenable for many thousands of people who like me could not re-charge a car at home, and in many cases may not be able to do so at their destinations either.

What of all those who live in large blocks of flats, flats above town-centre shops; terraced houses built before motor-cars were common, or even invented? (As I do)

In homes built without drives, on banks well above or below the road level?

In trendy modern housing-estates built to resemble olde-worlde villages, with limited and scattered parking areas?The vague hope was that such pseudo-villages, like the Middle Farm estate (so-called ' Poundbury ' ) near Dorchester, in Dorset, would include or be very close to the places of employment etc. of residents, whom would appear assumed not to have lives outside of home and work. I think it was Government policy not so long ago to encourage such developments precisely to discourage car ownership.

Such motorists have to take pot-luck on where they park; so will need ready access to convenient public charging-points just as most (though by no means all) presently have ready access to convenient filling-stations. And the time to wait in long, long queues.

'

I think vast numbers of people will be forced off the roads by cost and practicality

Electric cars are very, very expensive new, and not very likely to drop sufficiently in price for any but those who can also afford homes with private drives and chargers. Low-price second-hand battery-electric cars are likely to be too expensive for many because the low price is due to its costly batteries having about expired. Sooner or later the revenue lost by reduced liquid-fuel sales will likely force the government to tax car electricity, and that possibility may be why if you have a high-power charger at home it has to have its own meter.

Practicality? Well, as above. If you cannot charge the car at home you are forced to use public chargers, and what takes 5 minutes now will take (by equivalence) 15 minutes or more, per car - and for less range, so something needing very careful thought.

How do you pay, too? I have seen no charging-points with card-readers, apparently intending paying the unstated cost by "smart"-phone... assuming all motorists have or will want such a 'phone, good 'phone signals, and you don't mind the added 'phone contract and middle-man fees. It assumes the only charger for miles around on a dark cold wet night will be a) working, b) not in a radio shadow, c) compatible with your car and phone - the government making no attempt to enforce both easy payment and single-standard electrics.

For example, from my home in the South of England to my caving-club in Yorkshire is 300 miles / 8 hours by petrol car, with about 100 miles on ordinary roads. To my brother near Glasgow is some 400miles, 8/9 hrs, about 80 miles non-motorway. These would become expeditions, especially in Winter when I would need prepare for far longer times and take warm clothing, hot drinks, and even a precautionary sleeping-bag. At least if I did not carry much with me, both are accessible by train, via Bristol - the club is close to a station on the Leeds-Settle-Carlisle line.

.

I think many people's lives will become very limited or even very isolated; and all sorts of leisure and social activities, groups, venues etc. will be curtailed or ended, at great financial and cultural cost to the country with little real return for the overall good; climate-change notwithstanding.

Edited By Nigel Graham 2 on 16/06/2021 00:45:55

Do you ever park your car at a supermarket, DIY store, leisure centre etc etc that will in time all have dozens if not hundreds of charging points. Or does everything have to be done now, all at once. It took 25 Years for the first Petrol station to open in the UK.
If you’re driving 300 miles there are several EV’s that can do that. One of the Tesla’s does 400. The Highway Code though says you should be taking a break of 15 minutes every two hours - plenty of time for an EV top up whilst you’re having a coffee.

EV’s are expensive at the moment but the cost is coming down. Second hand models will trickle down as petrol models do. Only the super rich could afford petrol cars in the early days. ICE cars aren’t expected to be banned from our roads until 2050 so there’s plenty of time develop the EV concept.

EV Myths

I don’t yet have an EV but I’m hoping to get one when the price comes down a bit as they are much cheaper to run and absolutely lovely to drive I’m told.

Thanks Chris. The particular attraction for me is that although they are a similar cost to other inserts you get six cutting tips. I’ll order some polished ones to try.

Thread: Strimmer /BrushCutter any recommendations ?

Petrol powered tools used by gardeners have really destroyed the peace and quiet we used to enjoy in our village. Virtually every gardening “problem” seems to require a very noisy solution. I’m pleased with our battery powered mower but admit we don’t have a large amount of grass to cut. As for strimmers in particular I dread to think of the amount of wildlife destroyed by them every year. Hedgehogs in particular often seem to fall prey to them losing a limb or worse. I can only hope that Petrol powered garden tools get banned along with cars.
