Thread: Flooding
25/01/2021 05:51:24

Where I live, the willow trees were ripped out a few years ago (to appease the greenies).

Unfortunately, no native trees have been planted to replace the willows and so the soil is washing into the Mitta Mitta river and the fishing is declining angling waters

A large estate has recently been built on a floodplain near the Kiewa river in Vic, Au.

The property developer is a close friend of the local mayor of Wodonga.

Make up your own minds and conclusions.

Steel packing case strip can be usefully recycled as shims.

It;s quite consistent both in width and tihickness

Thread: Coronavirus death stats
17/01/2021 05:11:52

There are some places in Australia that refuse entry to people who cannot prove that they have been vaccinated.

Eg; Some child care centres deny admission to children whom are not immunised against measles and some aged care facilities deny access to people whom do not have a current influenza vaccination.

I would not be surprised if that in the future, such facilities might require a Covid-19 vaccination certificate.

IMHO people who refuse to be vaccinated (with a proven vaccine) are being quite selfish in putting tthe rest of the community at risk due to their intransigence.

Thread: 3D Resin Printers
17/01/2021 04:38:25

Thanks for the replies people.

The ability to print small details is important for my requirement to make multiple small cylinders for a dummy radial engine and also a contact at a local university has offered to 3D laser scan me (student training exercise) so I can make my pilots as minute replicas of myself (just need to find appropiate flying helmets).

Looks like I shall go ahead with the purchase as I use uv cure resin for some fishing flies and so already have a uv bench torch. Loon uv resins and torches

I have no experience with 3D printers, but appreciate their useful properties for manufacturing intricate components for model aircraft, such as dummy engines, pilots, corrugated wing skin moulds and also fishing lure prototypes amongst other things.

I came across this interesting machine here in Australia Jaycar 3D resin printer

It reminded me of the early stereolithography machines that I observed in the early 1990"s and then they cost big $$$ (used to prototype Holden bumper bars)

I know that similar machines are available from overseas at a cheaper price but I prefer the local consumer protection laws and warranty conditions.

So my question is: Has anybody used one of these machines and what are the advantages/disadvantages compared to a filament 3D printer?

Thread: Boring bar size ?
13/01/2021 10:49:30
Posted by Speedy Builder5 on 12/01/2021 06:51:00:

If you are not going to machine a standard boring bar, you will be limited by what you can grip in the tool post.

Why not make one to suit:-

Boring bar - home made

Right idea but crappy workshop techniques..

I winced when his drill press vice rocked visibly under the drill and the his filing rocking and rolling was horrible to watch. Was there even a handle on the needle files?

Definitely a bodger.

Thread: Sherline motor died
11/01/2021 11:01:29

My original (Australian) Sherline lathe ((brass bed) wvas powered with a sewing machine motor with a lamp dimmer as the speed control and a rubber 'O' ring belt drive. A bit scary at high rpm when the drive belt went a bi oval but a great lathe for making modekl engine parrts such as spraybars and needlle valves

Thread: The Repair Shop is getting to me...
11/01/2021 09:11:55

As for programs that turn me off are some, but not all, Australian fishing shows.

Most are just thinly veiled advertorials for the sponsor's products ranging from boats, sounders, rods, reels and lures they are often hosted by muppets who just want to show off their sunglasses and underwater cameras.

I wince evey time that I see a right handed bloke cast a rod with his right hand and the switch it to to their left (less dominant) hand to wind the handl. with their right hand.

Even worse are the ones who cast a fly rod, fight the fish with the fly rod in their right hand whilst stripping line with their left hand and the wind the fly line in with their right hand.

At one alpine lake that I like to fish, even the use of a mobile phone would get one the cold shoulder'
We go there to get away from all that crapola!

Totally inefficient and a poor way to promote the finesse of the noble art of angling.

Izaak Walton must be rolling in his grave.

Rant over, now back to the OP's topic.

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
30/12/2020 09:49:20

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

Thread: South Bend Heavy Ten Fixed Steady
30/12/2020 06:39:12

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.
