Alan,
Like you I can't post pics, forum tells me that the file is too big but I don't see a way to change the file size.
George.

Just posted a photo. I reduce the size by open it in paint reduce it & save with a surfix (a) so retaining the original.

That's the way to do it!

Hi George, when I use the upper add photos button I noticed that the resize title is not underlined and even though I've been useing that facility always it now says invalid file. So I tried the bottom attachments button and that said file too large so I resized in paint and and low and behold it worked. I don't like doing it this way cos it means I need a resized for uploads file in my pictures but needs must. I hope it will return to normal soon. I don't have a mac but do have an iPhone but when I downloaded ios5 my pics got all mixed up and I haven't got round to sorting them out. If I was starting again I'd certainly choose a mac. You live and learn right?
Jerry.

Thanks Jerry,
I have sent P.M. to Martin, so I shall wait and see what Martin has to say and if he can help.

When I go to the bottom ATTACHMENTS and OTHER OPTIONS the browser box comes up and when I put in a picture of my Yarrow boiler up comes where the pic is from, normally I would just click on the post button and Bob's your uncle , although in this day and age he might be my auntie.
but when I do this it tells me that the file is too big and 161kb is the max but there is no place to change it.
George.

First of all thank you George an excellent and informed answer to our question.

Now to my biggest bug, this bit about not being able to post pictures as we did before.
Good luck with your post to him George, he seems to ignore me but have been nagging him a bit.

http://www.modelboatmayhem.co.uk/forum/index.php?topic=11159.855

If all those who can't post pictures tell the admin. (Martin) on the link above, he may see that it's not just me that want's it back the way it was.
That's the trouble with us oldies! we don't like change.

Kerrsy......a little off thread...however if you go back & review...you will always find good comment from [Jerry C] & [Mick-patternmaker]

The postings ......

typically by these members are the learning curves to us all.......your Alaska build also has the potential to be such a build

Jerry C · « **Reply #108 on:** November 03, 2012, 11:12:09 am »

Derek, cheque in the post!

Kerrsy · « **Reply #109 on:** November 03, 2012, 11:43:27 am »

Thank you Derek
I don't think I'm in the same league as those guys but I really appreciate you saying so and from half way round the world!
I do hope they sort out the problems with the website soon as the format of this site is great.

I too have been watching the project and am fascinated at the time and effort you have put in to this, way beyond my present capabilities and tooling.
Grendel

derekwarner · « **Reply #111 on:** November 03, 2012, 11:47:12 am »

Kerrsy/Jerry & all ...again a little off topic
I am sure we all agree....it's a generational thing
I am a 1/2 baked 60+ year old engineer & can do most things reasonably well
My father @ 80 years was still a brillant engineer & craftsman... I will never be as talanted as he was
My father said that his father was the most brillant engineers welder & craftsman that he had ever seen
So keeping this on thread I understand my grandfather built a few planked rowing boats........
It's a generational thing........I can only aspire to be a better craftsman in the future...... Derek

Just thinking Kerrsy....you & my dad [Max] would have got on like a house on fire

.....prior to his retirement he was the Senior Welding Inspector for the Australian Iron & Steel group on OZ.......

Kerrsy · « **Reply #112 on:** November 04, 2012, 03:39:57 pm »

Hi Derek
What a lovely comment, thank you
I nearly went to aussy in the 60's we may even have met!
It,s great that it runs in your family.
Do have a build log ?
Alan

irishcarguy · « **Reply #113 on:** November 04, 2012, 04:20:12 pm »

You see Kerrsy all your thread needed was a little boost to have your talent & patience showcased for us all to see, keep up the good work, Mick B.

derekwarner · « **Reply #114 on:** November 10, 2012, 10:28:51 am »

Kerrsy....I have a build..... drew the plans & commenced the build in November 2000

...but no build log

Plank on frame hull ...with most brass bits purchased ....all the wood & most of the steam tubes will be mine....

I have no access to [adequate sized] machinery

It is my retirement project.......

.....Derek

Kerrsy · « **Reply #115 on:** November 11, 2012, 06:50:39 pm »

Hi Derek
The machinery looks great, I'd love to see more pictures of the actual boat and some details about what engine that is and why it's on the side.
Do you have enough to start a log? even if you just publish pictures of your boat I'm sure we would all like to see it.
Cheers, Alan

Look's to me like Derek's engine is configured to run as a paddle engine.

Kerrsy · « **Reply #118 on:** November 17, 2012, 01:05:27 pm »

Hi all
Just got to grips with this pain in the A"£$% system that we now have to go through to post pictures

Just lined a few thing up to see the layout, ignore the paint job that's work in progress.
Had to use a flexible coupling to line up the shaft, as in the original drawing the Prop shaf was going to line up with a D10.
The TVR being smaller, I've had to raise it up, but it is much more in keeping with the scale of the original.
My lack of boat knowledge and perspective, not knowing this engine has messed me up a bit but It's all worked out for the best in the end.
I don't normally do this but I have had such good service and it is such a good website for finding what pulley and what belt for a given centre that i must recommend
http://www.motionco.co.uk/pulleys-belts-c-25.html
You can mix and match Pulley and Belt and it will show you what centres you will end up with. Great.
So looks like it will all fit in the end.

derekwarner · « **Reply #119 on:** November 17, 2012, 02:27:14 pm »

Kerrsy.....the concept drive is fundamentally OK....

but you could consider an additional single bearing element to provent whip lash/vibration or and wear between the engine & the shaft coupling...from your image this distance appears to be approx 50 mm?
Idealily the bearing could be installed mid position between the outboard pinion on the lower drive shaft @ the engine end & the universal coupling
Other driveline builders may have an alternate thought

So as not to get too far off thread...yes my steam engine is a 9cc Saito Y2DR horizontal paddler.......& yes the retirement project .....Derek

Kerrsy · « **Reply #120 on:** November 17, 2012, 03:46:00 pm »

Hi Derek
thanks for the advice but what I didn't show was the two bearing housings under the engine.
These are 4 mm ball bearings in aluminium blocks that fit onto the shaft and hold it steady.
The shaft is 150mm long and at 4mm realy stiff
Thanks anyway
cheers alan

steamboatmodel · « **Reply #121 on:** November 17, 2012, 10:31:26 pm »

Alan,
It looks great and gives you a chance to play with different pulley ratios to increase or decrease prop speed.
Regards,
Gerald.

Kerrsy · « **Reply #122 on:** November 17, 2012, 10:50:23 pm »

Thank you Gerald
That's a good point but I couldn't go any bigger with the bottom one, It leaves options though
regards, alan

Norseman · « **Reply #123 on:** November 17, 2012, 11:27:08 pm »

Hi Alan

I lost your thread in the great meltdown and my previous posts appear as Mkenzig for some reason. Anyway I have reread it all and there's lots for people like me (steam curious) to think about. So I probably won't say much but I will certainly enjoy the discussion

Dave

derekwarner · « **Reply #124 on:** November 18, 2012, 12:19:49 am »

That rigidity is good Kerrsy......

....the toothed belt & pulleys will be the silent elements in the total drive assembly, but you are combining 19th century steam with 21st century components

You could always fabricate a shim brass plate box to hide the pulleys & belt......& then maintain the visual aura of that old time steam look

....
Bernhard BB......uses this method to hide or disguise components to great effect in his open hulled model vessels.........Derek
