No.9 Back 'Home' !!

.

Going back nearly 20 years I had just started to set up a home workshop (Deja vu) To cut a long story short the relationship I was in went south in a right royal fashion and I left leaving behind the machines (which I had only owned for a couple of months )

The other week my son mentioned to me a steam engine I had also left (TBH I had forgotten all about) Memory cogs start turning in my head and I recalled starting a Stuart No.9. So I asked him to bring it.

The photos show what I have :-

Obvious first missing is the drawing.!

I seem to have made a right dogs danglers all those years ago of the PCD on the cylinder ends. Although the covers fit they do so in only one position of rotation.

The main bearings don't look right somehow and one of the caps is AWOL. There may be others missing.

I know spare castings are available from Stuart's for this engine still, but I have mixed thoughts about 're-attacking' the project as in the last 20 years I have become more fussy about standards of finish etc. And I think I will be always looking at faults.

So what is the best plan for this do you think.? Also I am basically a 'newbie' once again to model engineering.

Cheers, Nick

Put it in a box and send it to me with your compliments. Pre-paid of course.

Pahhhh.!

You are not even offering a packet of Hob Nobs in trade.

Like you I started a Stuart Turner engine in my youth. It was a No.7a with reversing gear. When my life changed I put it in a sealed box with anti-rust paper and looked at it occasionally. After retiring a few years ago I was bullied into continuing it. I thought it would keep me busy between other projects but it, the reversing gear, took far longer than expected.

Yes, I was unhappy about some of my early work and decided to remake some parts. However I am moderately happy with the result.

I think you should try to finish the model whatever you think of your earlier work.

I rebuilt a S9 last year, it had been started, but was in a sorry state.

Nick, sent you a PM Ian S C

Is there any product available that will fill holes in cast iron and then enable them to be drilled and re tapped. Or will it always have a tendency to re follow the original hole.

Cheers, Nick

Drill and tap a bigger hole on the correct centre, glue in with one of the propriety "Loctites" and redrill and tap correct Dia.

Regards Ian

Other way is to have the hole filled with a high Nickel weld.

One of the studs on the front cylinder cover on mine was stripped, I tapped it 10 32 / 3/16" UNF, and made a stepped stud, think the studs are 4 BA. Another stud in the steam chest had to be moved, I drilled and tapped that and screwed in a slug of cast iron.

Nick,, please complete, I am doing a no 9 now, made a pigs ear of the end caps, so got a lump of cast iron off ebay , much cheaper than stuarts, and re-did them ok now, but not sure about drilling the exhaust port, into stean chest,, can you help me there,, can supply to you a copy of the building plans.

Terry Welcome to the forum, I have just posted one of your three attempts to post

The exhaust port is the largest one in the middle of the set of 3 on the valve face, this is drilled to one side of the cylinder block not into the bore. The other two slots are the inlets which are drilled at an angle to the top & bottom of the cylinder bore. The actual steam inlet is in the top side of teh valve chest
