Not today but over the last few days ,I've made these washers ,one face has a knurled finish and the other face is counter sunk .

Norman – Had the same problem as you sitting wise so wife and I treated ourselves to one each and the problem is no longer a problem.

Hi Rik

In truth I do have a chair similar to yours and it is pretty comfortable. I recently had a problem with a tooth which involved root canal treatment (ARG!!!) and lying down in bed was very uncomfortable. I took a duvet and some pillows up to my armchair, slept semi-reclined for a couple of nights, and that was much more comfortable.

I think that my wife has warmed to the idea of having a recliner too ( and will, no doubt, be even keener if I show her your post!)

( I still think flying to Australia is off the agenda!)

Regards

Norman

" I still think flying to Australia is off the agenda"

We to as well Norman. Flew back from Key West two years ago which resulted in wife sustaining a DVT and a 48 hour stay in the intensive care unit after the clot moved to her lung – I nearly lost her. She's on permanent Warfarin now and flying is strictly OUT. Never mind though, there are some lovely places we have yet to see in this green and pleasant land and if we wish to venture further afield our favourite – Venice – is a train ride away.

[Speedy Builder5Participant @speedybuilder5]

Had a friend who called round with an electric single phase pool pump.Sometimes it ran, sometimes backwards (he said) and some times just sat there and hummed.

There isn't any switchgear inside, so I guessed it was a capacitor run motor. Dug around in the come in handy box and found an identical 16 Uf capacitor. Fitted it and now he is a happy bunny again. So am I as I fancy a swim tomorrow.

Thanks Michael, they're fan brace washers to hold an engine in place on a model car , the idea is the knurl will bite into the chassis and the larger diameter and washer thickness stops the washers from splitting .

Hi Bob thanks for your interest , it took me a while to work out how to do the knurl ,I tried different ideas and a lot of head scratching ,I'll give it a day or two and see if any of you chaps can come up with a solution .

It will also give me a chance to takes some pictures of the process .

i made the handle today for the blower valve for my 5"g Terrier Stepney. the valve is a captive valve a variation of that described by Don Young for his Doncaster. it also has a steam feed below for the steam brake, as the terriers didnt have manifolds or turrets, i want to avoid as many steam feeds as possible on the turret i will make principally for the whistle valve. the blower valve handle is stainless and didnt take too long. the round part is 3/8" dia and will take a bit more work till im happy with the appearance of the spokes.

partly seen below in the scale 'tray' is part of a batch of 3/16" x 40 tpi union nuts i made on wednesday evening.

cheers,

julian

Thanks Raymond

I find the concept of the distances hard to grasp. My son lives in Melbourne and his partner works between there and Sidney – just nipping on a plane when required. (It's like going from here to Italy for a meeting !)

We have been watching a superb series on TV of a UK comic, John Bishop, cycling from Sydney to Cairns. It looks like a great country and these programs give us a bit of an insight – sadly I'm never likely to go there. Sitting in my armchair for any length of time is bad enough – the prospect of hours and hours cramped up on a plane doesn't bear thinking about!

Regards

Norman

Norman your not alone in grasping the size or distances as an ex-coach driver having driven overnight to Melbourne from Sydney 11 1/2 hrs, now it can be done in 9 hrs.
Or to Brisbane then 14 hrs now its been cut to about 12 tops due to major highway upgrades by passing towns.

Its like me watching UK shows being a Geordie learning about back home LOL.

Pity you'd love the place maybe a sea cruise or do as the boat people do LOL.

Get that weather sorted in Oz. Only 4 weeks 'til I'm at my nephew's wedding in Melbourne.
Now – must get back to shed base concreting.

4 weeks and how long you staying??

Here's why also see this link

4 weeks well thats September spring should be here but Victoria being Victoria make sure you have wellies

[Clive HartlandParticipant @clivehartland94829]

A few days a go I mentioned and asked if anyone was following the Rosetta probe that is chasing a comet and will rendezvous with it in 3 days time, there were no replies?

So, interestingly the Rosetta probe with a range of scientific instruments has already measured the comets temperature as -70C which confirms that it is mainly dust particles. with some ice as it also gives off water vapour, roughly 2 small cups a day. Pictures are now on the ESA Rosetta website showing the comet and its shape. The comet itself is travelling at 15.3 Km per sec. relative to the Sun and is some 540 million Km away from our Sun at this time.

Clive

[OuBallieParticipant @ouballie]

Been watching Clive.

Just not too much to comment on, but the photo of the comet's solid centre in the SMH is something else.

What an achievement to get one with such detail.

A great pity the politicians cannot get there heads out of their proverbial and do something constructive for the human race!

Back to bees now.

There are over a dozen Lavender bushes down our street, and they are humming with bees, bumbles and butterflies.

The residents must have dug out all the clay in the borders to get those bushes looking so healthy.

Wonderful sight, and GD captivated my the little creatures. Her hands are clasped to her tummy, and without our having told her to do so either.

Geoff – Recovering from an afternoon with her using the iPad.

[Neil WyattModerator @neilwyatt]

OK Clive, I'm visiting the Rosetta website for you now

I get the 'Sky and Telescope' newsletter for my astro-news. Perhaps they don't consider ESA missions worthy of mention?

Saturn and Mars very bright last night, with the moon lining up for the next pass. Vega overhead and Deneb bright in the S.E. seemed almost as bright as the planets. Sadkly we will lose Mars and Saturn soon, but Jupiter is creeping back.

Neil

P.S. Just about to post this when deep throbbing music starts, very loud!

[Martin WParticipant @martinw]

Clive

Another interesting part of this mission is the track Rosetta and how many slingshots it took as it wove in and out of the near planets, see 'Where is Rosetta' on the site. How they work it all out to arrive at a point in space at a precise time and speed with the required accuracy is beyond me. In makes fascinating reading and the images are now beginning to reveal more information. Landing is going to be interesting and any images Rosetta gets as it accompanies the comet around the sun at peak activity could be stunning.

Cheers

Martin

PS  Slight Correction to Water Loss

The comet is losing 2 glasses of water each second, Quote "ESA’s Rosetta spacecraft has found that comet 67P/Churyumov–Gerasimenko is releasing the equivalent of two small glasses of water into space every second, even at a cold 583 million kilometres from the Sun."

That's a lot of water per day and will only get worse the nearer it approaches perihelion.

Not really today, yesterday actually but I didn't get home 'til very late. I know this thread is supposed to be about stuff we made but this is more "what I did" Definitely along an engineering theme though. This was a six hour round trip – yes, I know it is shorter than that from Manchester to Coventry but I had to make detours to pick up and drop off a friend of mine, we went down to the lovely Greyhound Club to do a bit of field target shooting. It did pour down on and off but the company and great food at the pub/restaurant more than made up for this. The location is not easy to find, you need to know where you are going, but when you get there it is well worth the trip, this is the view from the outside seating area:

It gets better:

The place is Hawkesbury Junction, better known as Sutton Stop by the boating people and the "Roving Bridge" (would be grateful if someone could tell me why it is called that) leads down to the little building in between the two Canals which was the Toll House. In the background you can see what was a pumping station but is now no more than just a shell sadly. This Information Poster at the site gives a good potted history:

I think they got a bargain at £630 for the bridge and to all accounts that included delivery, wish I could get one for that!

Anyway, I hope you enjoyed that and there are some more pictures in my album.

[StovepipeParticipant @stovepipe]

Clive,

I'm sure that not the slightest snub was intended, and forum members on here are often interested and appreciated the reminder. Speaking for myself, I like to read about the results afterwards. Not being possessed of a mathematical bent, and being aware that all items in the universe are in perpetual motion, I never fail to be amazed at the sheer computational ability of the individuals involved.

One might also suggest that all we get from politicians is perpetual motion.

Dennis

[Robert Turner 1Participant @robertturner1]

A 'Roving bridge' is designed so that a horse towing a barge can cross from one side of the canal to the other without having to disconnect themselves from their boat. That's why the ramp one one side has a big loop. Without the loop, the tow rope would tie itself in a knot around the bridge.

Theres something very serene about canals, though 200 years ago, they must have been very busy carrying the materials and products of the early industrial revolution. From a design/engineering point of view, they are fascinating. They had no tensile materials to build from and very limited ability to pump water. Basically all they had to work with was gravity.
