I want to know how Dazza keeps his workshop so amazingly clean.... doesn't his swarf go everwhere like mine does? Don't his hands pick up grime and leave oily marks on all surfaces? Or is it magic??

Must be magic, mine sounds like the same as yours Malcolm.

All looking very impressive! What does the slomo mechanism in the tender do and how does it work? It is a geared flywheel to cheat mass, for slow and smooth realistic speed for the small garden steamers. With them one can shunt very nicely and not look 4478 going down Stoke Bank. smallsteamperformance.com.au/www.youtube.com/watch?v=LdtOTsi4um0

Malcolm Every month or two after some projects, I sweep up, blow the machines down and then mop the floor, before it gets out of hand. All of my machine tools are in cabinet/chest drawers, not on the wall, they rust in no time here in our summer humidity. In the next life I will put stainless sheets on the wall behind the mill so when the air hose is out it keeps the mess. My model engineering is to be enjoyed so I decided to not slum it, rather a nice ME workshop than a new bucket of nuts and bolts that I give donations to Petro chemical companies. So I have 17 year old station wagon. I am close to buying another roller cabinet and chest that is 1500mm long, for more storage of the fiddly bits of stock and materials. My material storage is terrible, it is here and there and any where. I might get that later this year when the $ become readily available.

That looks a lot like mine. 40 years plus of building for others leaves machinery looking tatty and well worn. [Have worn out 3 of thost cheap but indispensible band saws] Storage of short lengths of material is a real bind as it doesn't pay to throw too much out.

Is that the one that works a bit like KERS in F1? The flywheel gives a form of inertia to the whole caboodle.

Hi Dazza, if the slomo is in the tender how does it start to spin when the loco moves. I would have thought it might just drag the tender round without the wheels turning. I know that it must work because I have heard of them being fitted in wagons but it would be a lot easier to keep the weight constant in a wagon than in a tender. I would love to hear your thoughts on this.

I know that it must work because I have heard of them being fitted in wagons but it would be a lot easier to keep the weight constant in a wagon than in a tender. I would love to hear your thoughts on this. Mike It is best to have a Slomo mech directly on the loco drive axle, but I learnt about the virtues of the Slomo mech far too late to do that, so a tender mount was the solution. This has been done many times before. There is a chain connecting up the Slomo to the two tender wheels. Skidding will occur if the tender is too light but this tender already weighs 2kg. I tested with a simple push and all worked well. If one goes too quick it does skid and then pick up, but at normal operation it appears to work to expectations. I may have to add 500grams to the front of the tender to even up the axle loads. They make a wee whirring noise which some complain about but those who do complain seem to not mind jerky moving garden locos at slow speed and seem quite content to see a NG 16mm loco doing a scale 126mph . I will take a photo of the set up in this tender next week. Right now I am off to Gympie for a weekend driving and firing steam.

Aiming for 15.95mm , I am happy with that. Pump eccentric, some final finish work tonight. I am not entirely satisfied with it and my processes, but I will get over this.

Llewellyn Loco Work's Captain Plod made the arm last night. Got to make 1/16" rivet snaps tonight, then onto the ram, case hardened pin and a wee bronze bush to go into the arm.

Last Friday, up to Gympie, cleaned 974, Saturday lit up, 5am the lit rages went in, not breath of breeze in the shed and the light up wood was a bit sappy so smokey till it was well caught and hot, so 10 mins was spent outside the shed with a strong Brownian Motion producer till it cleared, 90 mins the needle moved which is the norm if done right, then fired the AM trip, handed over to arvo crew at the table as I would be out of hours. Sunday drove S10 and S11 out and back, then 2 hours drive home, then the two beers.

Malcolm The good fortune we have here is not lost on me. The active Covid cases in Qld yesterday was 6, all of them in hotel quarantine and they were all imports via returning citizens, no deaths for months and months. The advantage of a moat of water around us and stopping international travel hard! Tourism in many sectors is being bashed up, but the consequences other wise is horrible. A lot of businesses are actually booming and at times it is the usual " do not let a crises go to waste" . The Mary Valley Rattler made good profit and is doing well with local tourism.
But, it can all change tomorrow.

Half your luck Dazza! some great beasts to play with. Yes, I am living the dream. I have waited decades to do this and the stars and planets have lined up. I have slowed my rotation on the roster to an average of every three weeks up to Gympie. After one week I have the urge to get back. Meanwhile I sate my needs in the Red Room, I want to try and paint this little loco next year. Then start my 5" C17 or perhaps a 4 1/2 Foden Steam Lorry. I like steam lorries.

The lads at the Llewellyn Loco Works ponder a start on their first ever boiler fittings, the phosphor bronze was brought up from the stores, however before the swarf is flying about, a clean up of the workshop, floor mop was done first to clear the craniums.

Question to the collective wisdom What is the name of that product that you heat in a saucepan and pour into pipe/tubing for bending purposes and can be melted out at how water temperature and reused ?
