That's her, looking smarter than she did in 2000!
Fortunately the Lyttelton Preservation Society is very active and there are many photographs available from them. One of your photos shows some great detail of the anchor winch which will be very useful. Winches are almost like a fingerprint for these old tugs, seldom seeing two alike. Occre's offering is fairly poor, so I'll happily bin it and make a Lyttelton replica. ▲

Hi Nonsuch,
The hull has came out really well. Keep up the good work. It would be nice to see some more photos of your steam plant. Martin555. ▲

Lovely engine NS,
Looking forward to seeing some running on steam shots at some point. Cheers, Stephen. ▲

Good looking engine.Sounds as if the engine will have good power to run the boat. Do you know the make of the engine.Will you be putting in a boiler or will you run the engine with a motor.You probably know this all ready but if it is steam for the boat.You will need full access to all fittings and will need a condenser for contaminated steam from the engine. Good luck with the build.

Just spotted that Ebay seller "Galgig" has items listed again. He seems to have changed to model vintage four stroke stationary engines. If you "visit sellers shop" he has a twin cylinder marine steam plant advertised. Consists of engine with reverse, boiler, burner, gas tank and condenser.
Says it's the last one and is at Β£900 including free postage. ▲

Thanks for raising a doubt. It appears that the "under 3 bar litres" is no longer an exemption. It was dropped in the 2013 UK rule ammendment.
The rule now only stipulates the working pressure of 3 bar. As the boiler volume is only 0.42 litres it would have been well under the previous regs. It's probably best to send it for testing and let the examiner decide whether it needs a certificate, but with the rule change I suspect it does. ▲

Funnily enough model loco cylinders are either PB or cast iron! Brass was good enough ough for Mamod

Your comments on boiler certification are correct as a general assumption but be aware that different countries have different specifications for model boilers Australia being one of them
Normally 4 inch diameter copper drawn pipe with a suitable wall thickness works around the certification Good Luck and enjoy the build ▲

Keith Appleton is a YouTuber whose channel deals with model steam engine troubleshooting and repair. He does a review of this exact Microcosm engine and gives it the thumbs up. His only reservation is the brass cylinder block rather than cast iron. But as he points out, a few minutes running round the pond isn't like a 5" loco hauling a carriage full of young children for several hours at a gala.
Plus if it wears, you just swap out the silicon piston ring. They should be quite good enough for the likes of us. ▲

Thank you for your reply.Great find and price for the plant. Steam engines and boilers are very expensive and hard to find on line. Any thing I've bid on most times gets out bid.I do keep looking.

I would say the nearer to the engine the better with regard to the lubricator, and the simplest quick fix would be to empty it using a syringe, replace the needle with flexible tubing.

Thanks for the comments. I share your concern over the lubricator and am considering moving it. Currently it feeds back into the regulator valve and then into the inlet T piece (manifold)
I am thinking of putting a T piece into the main inlet pipe, just ahead of the regulator. This would place the lubricator running transversely, just infront of the engine. Much better access, although it would mean locating the lubricator on the boiler side of the regulator. Is there a reason that the lubricator should be on the engine side of the regulator? ▲

Very nice to see yet another convert to Steam, and that has to be the bargain of the year your boiler and a very nice steam engine for less than half price. I also managed a bargain out of Mr. Galgig an automatic gas control valve as the only bidder. I am wondering about your engine access especially with regard to the bottom drain valve on the lubricator? Mind a really nice hull you have there, and wishing you every success with your build. Regards, Gary. Attached is a photo of a Cheddar steam plant to go into a Mountfleet Clyde puffer hull.

Doesn't matter if it isn't what others do. Making it easy to work on or repair is the bottom line. I think you did a nice job and it looks good to boot.

I mount my rudder this way too. It makes sense to be able to remove the rudder easily, then work on the wheel and shaft.

Hi Nonsuch,
Lovely fitting it is a big improvement over the original cast one. Clearly Occre didn't put much effort into the kit, grabbing a prop and rudder out of their parts bin and throwing it into the kit, saying that will do. Cheers, Stephen. ▲

Thanks for the info.
As you say, "who's going to know?" I'm finding it difficult to not follow the plans and use a reference photo. I got carried away and added all the bollards round the bow and stern hawse eyes but they're Ulises not Lyttelton! As they won't come off without leaving scars, they can stay. At the end of the day, all I really want is a live steam tug boat that looks pretty. (Purists accept my apologies now!) ▲

The motor and boiler are out of the boat at the moment. I have been bench running and checking working pressure. It runs at 25-30psi and max's at about 42psi with the regulator turned off. In my mind test certificate exempt.
I have just bought a roll of copper pipe and a mini pipe bender, so will take photos of the reinstallation and post here once working again. I'm experimenting with a second superheater set up to replace the condenser. Condensers keep a lot of heat inside the model and unless you have a boiler feed pump are simply emptied out periodically. Their purpose is basically to prevent hot water squirting up the chimney. I am trying a second superheater coil for the motor exhaust. As long as the coil is hot before the steam regulator is turned on, no hot water is blown out. No problems there then? What I do have is a fabulous amount of steam from the chimney. It looks great, but the jury is still out on that one! Mike ▲

The new motor came from the guy who supplied the original vertical twin and boiler unit. They're branded as "Microcosm" but the only outlet that I know of is on Ebay. His seller name is Galgig. He lists a few items under "steam" which annoyingly is found under "toys and games". Once you find one of his items visit his shop, as he by no means shows everything in the listings.
He's in China and although his English is far better than my Mandarin, communication is basic. I have dealt with him three times now and consider him an OK guy. Mike ▲

I'm realising that the detail is what I really like doing best. I was obviously always suited to static sail and am now itching to finish the tug so that I can start my next frigate build.
