Thread: Chuck backplate error
09/01/2021 06:26:28

Maybe the interesting article in MEW # 292 ( April 2020) by Jacques Maurel re: Adjustable 3 Jaw Chucks could be of use for people seeking precision?

Given all that, I found that soft jaws are an easy alternative solution and easy to make.

Thread: Turnbuckle manufacture
09/01/2021 03:12:55

Thank you very much William.

Excellent work that has given me a few ideas. The little jig for milling and drilling the flats is going to be handy for a star't.

As one of my models is a Free Flight BE2e I want the rigging to be functional and adjustable for trimming purposes, hence the turnbuckles.

Here are a few photos, more in my album BE2e

Thanks for all the repies people. I shall check out the various suppliers and as postage can be a factor it makes sense to buy a single die nut and multiple taps in one go, (Also handy if I break one).

I also plan to experiment with aluminium alloy tubing to speed things up a bit.

G'day all.

I have decided to make some small working turnbuckles for rigging some of my model aircraft biplanes, so plenty needed in a few sizes ranging from 8mm long to 16mm long.

Body material 2024 T4 aluminium alloy (I have plenty) so have devised the following machining sequence.

1.Turn outside to turnbuckle diameter.
2. Drill for tapping size through appropriate length
3. Tap to just under 1/2 length with right hand (conventional) tap
4. Part off
5. Insert threaded rod into tapped end (to prevent collapse) and grip tapped end in soft-jaws drilled appropriately to suit diameter
6..Tap left hand thread
7. Move to mill to drill the x-;hole

My biggest problem is locating some left hand taps and dies for the holes and connector ends. I have decided to use brass for the connectors btw

Typical sizes range from 8BA or about 1mm to 2mm for the larger models.

I can mess around on my C3 minilathe with silver steel (I have both imperial and metric leadscrews, gears and threading dials} to attempt to make a tap and a die or just maybe it would be easier to just buy a left-hand tap and matching die but the respectable suppliers seem to be asking quite a bit and I would rather pay a fair price buy once than some crapola from an unknown vendor on Ebay.

All constructive comments and ideas are welcomed.

Thread: ME magazine late again
04/01/2021 12:02:31
Posted by Eric Cox on 04/01/2021 10:18:10:

Once again I'm awaiting delivery of the latest issue of ME magazine (4655), Is there any reason for late delivery or am I just unlucky.

Oh dear, with current restrictions affecting publicatioin and postal deliveries you are fortunate and should count yourself lucky that any magazines were published and delivered at all.

I just received (4th January 2021) a Christmas card from my sister in the UK, it was posted 11th December 2020.

As for a reason for 'late delivery' consider keeping up with the daily news. There are a few major issues affecting our daily lives at this time..

I was absolutely astounded when all my 2020 copies of MEW actually made it to Australia.

So please be patient Eric, there are a few greater problems affecting the world than your timely delivery of a magazine. Hopefully it should arrive soon.

Thread: Motor for a gyroscope.
01/01/2021 02:50:41

When I used to teach radar technicians about gyroscopic precession in a ferrite isolator my demonstration model of choice was the front wheel from a bicycle with a pair of wooden handles attached to the hub.

I used to get the students to hold the handles while another would spin it, then told the student on the handles to twist the wheel.

They soon learned about gyroscopic precession.

Thread: Christmas Disasters!
31/12/2020 04:47:33

On Christmas Eve I stopped by the local road block (NSW-Vic border) and told the policeman a joke about why the Indian cricketers could not be infected by the corona virus (they cannot catch anything that comes from a bat).

Poiceman pulled down his facemask, yep, he was of Indian descent. OMG, how embarassing!

Roll on just a few days later and instead of Indian, insert Australian cricketers and the joke still works.

Next time I am stopped at the road block I shall just answer "My mum told me never to talk to strangers"

If you never hear from me for a while it's maybe because I am in gaol. Do prisoners get internet access?

Thread: A white xmas

No such weather here down-under, actually a mild Christmas, no 40°C days so far and thunderstorms for the next few days.

This time last year bushfires were rampant but now we have. **LINK**

So have to keep an eye on them as lightning strikes caused most of the fires

Have a great new year.

I have an idea to market toilet paper printed with "2020, put it behind you" just to wipe away the memories of a realy crappy year

Nice lathe the SB Heavy Ten.

I have a few contacts in the US who use them for gun-smithing duties as they can fit a rifle barrel through the headstock and using an outboard spider they can cut and ream a chamber for custom rifles.

Wouln't mind one.

Thread: Christmas Cracker Jokes .. and similar

Why does the Indian cricket team not have to go into isolation?

Because they can't catch anything that comes from a bat.

Thread: Cannot let this pass without comment
25/12/2020 02:14:59

Given the low RPM of the lathe and (presumably) low torque then the ingenious use of a high speed rotary cutter makes sense.

+1 for ingenuity

Thread: Mery Christmas Everybody

Best wishes to all the forum members and MTM people (especially Neil and the moderators) for keeping this a safe place to forget about the news and just de-stress.

Also thanks to whomever waved the magic wand to ensure that all my copies of MEW arrived at my local newsagent in a country town in Victoria, Australia. Awesome!

Here's to a better 2021.

Eating local tiger prawns, lobster and oysters for a traditional Aussie Christmas lunch, washed down with some VB tinnies and Australian wine.

29°C today so took a Christmas card, a tin of toffees and some fresh apricots to the police who man a border control checkpoint near my home. After over 30 years military service I know what it is like to be recalled from leave at short notice and deployed at Christmas.

So here's to all the police, testers and medical staff who are working hard to keep us all safe

Thread: Covid19 - Overseas Subscriptions
22/12/2020 04:13:22

I visited my newsagent (Wodonga, Vic. Australia) today for the first time since March as I only usually have two magazines on regular order, both from the U.K. and after reading about distribution problems I sort of gave up on ever obtaining a recent copy in these difficult times.

Well imagine my surprise when the lovely lady told me that they had all my magazines ready to go and there they were! MEW complete from March - October and most of my Aeromodeller magazines.

I felt a bit embarrassed that I had not visited sooner, but with all the doom and gloom forecasts there was no way that I suspected that these magazines had slipped through the hoops. Happy to top up the till for my local newsagent just before Christmas. Didn't even have to wear a mask after months of trying to do the right thing.

So all's well that ends well.

Have a safe and happy Christmas and let's hope that 2021 is a bit nicer than 2020

Thread: Jobs we had as kids
09/09/2020 09:22:43

I forgot to mention that many of my local peers were into drugs. I remember the names blues and bennies and was horrified after what I saw the effects that they had on them.

This was a pity as they were pretty good kids to grow up with but come 15-16 the dealers got their hooks into them.

My late dear mum once remarked I did not get sucked in because I was too busy building model aeroplanes and working. Very astute mum. A few of them died of heroin overdoses before reaching 18.

Also managed to fit in 4 years at the Army Cadets (the annual camps were my holidays), and learned many useful skills (map-reading, rafting and rifle shooting) among others.

Nowadays I notice a lot of 'umbrella kids', sheltered from the big cruel world by overprotective parents, left alone with Facebook imaginary friends and totally unprepared for the real world. A local teenager was run over while chasing an imaginary 'Pokemon' with his mobile phone, very sad.

As a young bloke growing up in the East End of London, it seems that I always had a job of some sort either after school or on weekends.

The majority of my wages went to the family (6 brothers and sisters) but my parents never pressured me to seek the work, it just seemed the right thing to do.

So here is a list of the jobs that I did, some paid quite well.

Age 12-14 paper rounds. The tips of sixpence made it worthwhile as the wages were lousy.

Age 12-16 washing cars at the local pub each Sunday lunchtime opening. Made a few quid at that one.

Age 16. Spent school summer holidays humping coal up stairs in multi storey flats.The workout toughened me enough to sort out a few local bullies who were hassling my family. Pay was ok

Age 16-18, Glassworks in Homerton E9. Loading glasses into conveyor belts to go through fusing furnacxe or unloading after the transfers were fused. - Very hot work.

Age 17 School summer holidays full time at the 'Metal Box Factory' in Hackney. Wow, could those ladies solder, learned a lot there.

Age 15-18, Resident guru at the local second hand shop. If I fixed a broken item I got paid so electrical items were my favourites. Nickname was 'brains'. The owner was a survivor of the Nijmegen paratroop drop into Holland and had just lost his son (about my age) in a motorcycle accident so I finally figured out that I was replacement son. Finally gave that job away when I discovered that taxi driving mates were delivering dodgy goods (stolen goodsand pistols) .

A lathe was but a dream but I did manage to save enough to purchase a few model aeroplane engines and kits, usually from Henry J. Nicholls shop at 308 Holloway Road,.

Lol, a bit of a rant but that is what it was like in the 60's for a kid in London.

So how did the rest of you survive in the age of flower power and hippy culture?

Lumiweld works well if one carefully follows the instructions.

My first attempt restored a broken out mounting lug on an ancient DC Dart model diesel engine,

Apart from the fact thet the repair is a bit darker than the original it's still working quite well 20 years later
