seeing the mounts were all prepped decided to work on the thrust box,, the casting halfs were filed flat and loctited together,, milled and drilled for the through bolts, drilled for the mounting studs,, fitted a thin brass tube in place of the shaft to use as a drill guide,, drilled the box and then finished up things with the reamers.. the box is mainly for show but will provide some shaft support.. a condensate pump  driven by an eccentric will be outboard of the box..

spent some time today with the opti-visor on making the cylinder cocks,, wanted to make them as small as possible trying to keep the scale look.. they still need the drain hole drilled but will do that when they get installed so it will be correctly positioned..(I'll make a nice brass spanner to work them) made up the fitting for steam admission on the HP chest top. polished the valve faces of the block and the valves.still have to make the travelers for the box links and the brass side and top panels,,

a bit more of the the small stuff,, made the valve shafts with some silver soldering.. the link sliders were made by cutting and filing some brass stock(had to mill it to correct thickness first) when the crescent shaped piece fit in the groove of the extra link stock it was drilled (using the stock as a holding fixture) the the separate guides were cut..lot of small drilling and filing, but it feels good and moves smoothly.. may have the grind down the bolt heads of the rod bolts for clearance along with the lock nuts on the back side..

slim seems to like shiny objects,, gave him a big one today  work on one of the engine shrouds is being fitted,, lots of fun forming some sheet brass,, made a pattern with a piece of heavy-duty aluminum foil.. still have to make the other side and decide if they will be soldered together at the top center seam..

Wow, that really changed the look of the engine. Did you make a wood form, or just bent over the engine? Very clean result.

used a few pieces of round and square stock to get the basic side shape,, marked for the top bends and used a bench anvil and stock in a vice to work those into shape,,marked and trimmed for the cylinder tops,,  it really does change the look.. the foil pattern helped greatly..

finished the other side shroud and it was soldered to the other,, kind of just set everything in place to get a good look at things,, there are a lot of parts involved here.. will have to get started on a boat frame section for a test stand..

Looking fantastic!    :popcorn: :popcorn: :popcorn:




Oh, and don't forget to make Slim  a 'life' jacket, unless you fatten him up on cookies he won't float to well!
