    We had a boat, not the size your talking! it had a Volvo Penta Diesel- if you ran the engine for any considerable time and one was sitting down, one got 'white Bum' you know like 'White Finger' using a B&D mouse sander... Eoin

    Yes Borithe the main problem with steam loco design, - build it big and hefty, replace it when it comes loose, and no need to change the existing design 'because it works'. This is the design ethos that got steam a bad name... Motor bikes got smoother when the Japs got involved with their lightweight engineering and more modern ways of thinking! I have a few British made 'Thumpers' - a 1961 BSA C15T 250cc single is the worst- at about 30mph the vibrations make it difficult to hold the bars, above that it smooths out again, then close to 60mph about as fast as I dared to go- your vision blurs, there is a brand new Alpha big end bearing kit installed n all!

    Hi KMCE It's quartered, the chap who built the chassis has the left side leading The wheel balance weights are essential on large wheels to counter-balance the weight of the crankpin boss cast in the wheel, the crankpin, and the motions. The inside cylinder is far ahead of the outside ones because the drive is taken from the front axle and the radius rod driving the valve needs to be as long as possible to set up the correct motion angles with the combining and anchor links to control lap and lead to the valve ports.....

    Hi popeye It all runs smoothly on test but the valve rod does have to much slop in its bore, as suspected! I will work out a sleeve solution on the second cylinder and then apply to both..... Here are a a few photos of the engine break gear and wheel balance weights erected, these cast iron wheels are really nice it seems such a pity to paint them! The break gear is 180deg soldered and the wheel weights were epoxied on, again like the tender I left a generous gap between the break shoes and wheel tyres for wheel removal for the painting work. Now to complete the other side valve gear..... Eoin

    Hi jb It would most likely be a tank in some form of bund- a structure that would hold the full contents of the tank should it leak. The bund walls would be about 1 to 1.2 meters high built of brick or block and lined inside with asphalt in the early days, constructed in concrete with no lining later on. The tank would stand on two rising walls within the bund and the tank would be at a higher level so that if the bund fills the tank would be above the full level and not float! It would not be in an enclosure like a building, generally open above the bund for ventilation. A small discharge metering valve located at one end with hose and standard nozzle would be the associated gubbins...... Eoin

    Hi Ken A fantastic aid to lining- by Wild Swan Publications - 'A Modeller's Handbook Of Painting And Lining' by Ian Rathbone, and Wild Swan's first publication of this type in full colour..... Truly a must have item in the toolbox ISBN 978 1 905184 54 5 Eoin

    Hi KMCE In the 'good book' photo, one can just make out the lining on the cab side around the numberplate, and on the sand/tool boxes- tool box top is black also? the links below give some idea as to how Packetts were lined which could help you - the last photo in the first link would seem a good starting point with the black lining and then add the yellow?? https://www.martynbane.co.uk/peckett/working/inservice.htm https://en.wikipedia.org/wiki/List_of_Peckett_and_Sons_railway_locomotives Eoin

    Hi KMCE 'expletives' a very handy modeller device- somehow by multiple use it all works out OK in the end! Looking Good Eoin

    Hi Noel Nice to see those photos, brings back memories when used to holiday there, worked there, and sailed there- when sailing we stayed in the old station- there used to be a sailing school there- Glenn Ann's I think it was called! Eoin

    This evening I got the 800 trial valve gear side erected, after steel riveting, 14BA tapping and a few nuts soldered it all came together. These are the 800 detail valve parts soldered on to the chassis plate, those cheese head screws are temporary, brass countersunk ones will be used finally. The crosshead is going to miss the combination lever- phew! The slide bar chassis hanger is now soldered in place and the slide bar needs a bit of a trim here. The valve rod is a bit sloppy in its cylinder and I'm a bit concerned as to how it will work under power! but cant test run it until the Loctite sets overnight on the return crank- then I need to shorten the crankpin screw as it fouls the eccentric rod! The return crank should be soldered to the crankpin, but the whole thing needs to be dissembled for painting- soldering will be done after the painting is complete. Eoin

    Today I erected the tender break gear..... The chassis holes for the hangers was worked out very carefully, as the chassis sides were not identical so I used the height gauge to measure and mark the holes from the axles. The chassis has a slight twist in it which also caused some line up problems after the holes were drilled! After some work with a files, a broach and 'gentile persuasion' I set about soldering it together with 180deg solder. I left a good gap on the break shoes and outer lateral break rods so that the wheels can be removed for the painting work. Thats the tender chassis work complete, Eoin

    Hi Mayner It's a Stepcraft 420 with a Kress router/spindle- it also takes a Dremel, the 450 has a working area of about A3 size. They have other options for this machine- wire foam cutter, knife cutting and 3D printer, and fourth axis option- rotary table..... http://stoneycnc.co.uk/stepcraft-overview/ There is also a photo at the start of the thread Eoin
