That look great Tug!
There are some pretty fussy little parts there, nice job.

Whoa - another show of your level of accuracy (of what could have been part off the installation)  :praise2:

Kind of makes one wonder if this is an engine, a Museum Display Model or a piece of Art ....  :thinking:

Oh and I fully understand that you do it this way because this is what gives you pleasure - not in order to impress others .... though we are anyway .... like with a number of other peoples work on this site  :cheers:

Take care and thanks for showing Tug  :cheers:

Hi Guys just to say I've finally finished with the brass  ::) and happy about that too - not one of my favourite materials to machine.

Just the governor mods to do and some pipework on the condenser along with the final 1mm pipework on the lube 'system'. Talking of that I think these are the smallest 'accuratly dimensioned' things I've ever made. Olives for said pipe at 1 mm bore x 1.6 od and a 30 degree taper. Well aware it's not watchmaking its as close as I want to get though!  With  the diameters the same they require a slight tweaking with a fine needle file to fit the pipe and will be located with a smear of loctite rather than an attempt to solder them in place



Also need to do some glass cutting but more on that later.

Thanks for looking in guys - not long to go now  :ThumbsUp:

Regards - Tug

Hi Guys - despite the lack of posting I have been beavering away to get this all wrapped up before the festive season (Hmm what festive season)

nearly there but thought you might like to see the governor mod ready to fit. Doesn't look much but the time it's taken is well out of proportion to it's image. Also took the opportunity to add a raising block which caused a few fit issues but after several assembly and dis-assemblies today it's working okay



The dashpot is much smaller than that designed - that looked a bit overscale - but it works okay using the steam oil as before.

Not long now and I'll 'reveal all' - very little left to do

Regards - Tug

PS cnr - spanner now back in the box marked 'extra big spanners' ;)

That looks great Tug.

Your attention to detail is really going to show in the quality of the final model!

Looking great Ramon.   :ThumbsUp: :ThumbsUp: :ThumbsUp:

 I'll bet the 2 ton overhead hoist came in handy getting that big spanner back in the box.  :Lol:    :cheers:

Hi Guys - thanks for looking in  :ThumbsUp:

Well to coin a phrase 'The end is nigh'! but there are still a couple of small items that need attention.
One of them was the need to do some glass cutting - no not 4mm thick for a case but something a tad thinner!

This afternoon I cut four pieces 8mm x 11.5mm from a microsope glass slide. I purchased a pack of 50 to hedge the expected potential scrappage. When they first arrived about a month ago I had a quick tentative go but three slides later decided it needed a slightly more controlled approach rather than the quick have a go and see what happens scenario!

So, taking my time I managed to get all five 8mm wide strips plus one scrap from one slide then successfully cut the 11.5 length on four of them - I used a carbide scriber made from an old discarded cutter and lubricated it with white spirit. Once scribed and placed over the wire along the line the glass cracked quite uniformly under finger pressure.

This is the 'kit' and the remaining waste glass - the pencil lines are the  dimensions required. There are  about five sheets of copy paper underneath to provide some give when pressing down on the scriber.


These are the actual pieces required along with their receptacles (oilers for the main bearings)


Yet one more fiddly little job accomplished these will get epoxied in place tomorrow  :)

Regards for now - Tug

Well I'm pleased to report that the initial test on the lube system proved successful up to the outlets on the distribution block. Whether it will push it further through the microbore tube remains to be discovered.



It has raised another mod required though in that, of course, a check valve will need to be put into the system somewhere - I think I may be able to modify the inlet to the block to act as such.

Biggest problem at the moment is computer based - I have been having real problems opening pages and particular my photos - this one pic has take the best part of the morning trying at intervals to get it into the album to be able to post.

It is intermittent - sometimes a blank page with 'This site cannot be reached - Google has taken to long to respond' message quickly followed by another blank page with 'No internet connection' and everything just sitting there sulking.

The internet connection is bloody secured and connected however.

Does not bode well  :(

Time for an upgrade in the New Year me thinks

Hi Willy - How are you? I hope you are keeping well with all that's going on around us.

Not so sure about the 'museum quality' but it will be going to Forncett - hopefully.

Stay safe - hope to catch up with you sometime next year
