    Beautiful workmanship as usual Rob. This is going to be a terrific build.

    Thanks Tom,

    Once the rear bulkhead was soldered in, next up I concentrated on getting the many details on the rear of the tender added.

    It's quite busy back there...

    Just read the whole thread and I'm impressed by your quality workmanship. You do crack on with these kits at a rapid pace. Great work, keep it coming.

    Cheers, Gary.

    Superb workmanship in the making process as usual Rob,:tophat: interesting that access ladder isn't vastly different (apart from the length extending below the buffing beam) from the BR standard one I've been working on tonight. I think these threads make for a great comparison in tender designs.:thumbs:

    Thanks for the kind words All,

    Following on as you might expect from detailing the rear I started adding to the front Bulkhead and the Inner coal space.

    Now getting nearer to the finish line - I didn't get it finished on Thursday evening as I had hoped:(

    The final chapter on the tender ended on Saturday morning.

    Up the thread Gary said:
    On the conservative side I have 49 hours in the tender alone. I am now on with the loco chassis.

    Hi Ron,

    It came with some Premier couplings, which along with the tender axles boxes will be fitted by Warren Haywood after painting.

    A couple of things Rob. Just how much handling will the tender take given all the detail. Do these parts come off easily or will they take the odd nudge ? Prior to painting, how much more cleaning ( and how is it done ) to get the model free from the odd bits of grease and debri to enable a nice clean finish ?

    cheers

    Hi Toto,

    Because of the design of the tender prototype and the battleship plates that make up the tender sides it is remarkably robust. The flares at the back protect most of the detail and scrubbing with Shiny Sinks and a toothbrush after completion only had me slightly bending the top of one side of the ladder and dislodging one of the L shaped levers on the tender front.

    Compared to other builds where the scrub down has left me with bits in the bottom of the sink I count myself quite lucky.

    Usually I rinse after each soldering session, if it starts to get really grubby I dunk in a solution of soda crystals to kill the acid of the flux (Soda Crystals are Alkali) before scrubbing with Shiny Sinks or if it's really bad Bar Keepers Friend I use a combination of old toothbrushes and plastic pan shiner sheets which I cut into little squares for scrubbing brass work.

    Before it's painted Warren dunks it in cellulose thinners to clean prior to priming and because it can be some time before he gets to painting it no matter how clean I deliver it, it will have tarnished by the time he paints it.

    So it's onto the loco chassis,

    I made a start on Saturday afternoon and up to last night I had made it to

    Which brought me to the end of drawing number 2 of the chassis instructions.

    I made one minor error in that I got one of the chassis spacers/supports the wrong way up which meant that the hole for the brake cylinder was in the wrong place. Rather than take the chassis apart again I just redrilled the hole at the other end of the spacer and filed the tabs of a couple of brackets that should have fit into some slots. Job done and brakes fitted as they should be.
