So, for those of you watching :paranoia: ....

Got the last of the steam chest mounting holes drilled/tapped/assembled:

Then I started laying out the lines for the recessed panels and lettering in the lids, which will look like this:


It quickly became clear that this lettering is a LOT smaller than the ones on the track supports, and it is not really practical to carve it in myself like the supports. So, I think I will do like I did on the Lombard boiler front plate, and have them photo etched and inset them into place. Does not cost much, and looks really nice. So, will make up the artwork for these panels (smaller ones for the steering engine too) plus the numbers for the boiler doors and send them off.

Thanks Gary - still quite a ways to go on them, but all the big parts are there now. Next are all the internal bits, conrods/pistons/valves/levers/ports/passages/glands/etc.

Dog you been working those poor elfs overtime man give them a break..... :lolb:
Looking good Chris and looking sweeter then a bowl of sugar... :ThumbsUp:

We had some warm weather today, so all the elves and I hopped in the sleigh and went and took my mother out for lunch and a walk - then I threw them back in the shop!   :LittleDevil:

If giving them a brake doesn't work threaten to but them in that dimension where the days are 40hours long and they have to shovel coal.
PS The big guy north of me (I am not talking about Brian) wants the sleigh back something about a recall on the brakes.

So if the brakes break, can I just throw a reindeer under the runners?   :LittleDevil:

Chris,


I am greatly relieved at your decision to have the letters and numbers photo etched.  If you had attempted and succeeded in cranking that out on a manual mill, I would have had to revisit my thinking regarding the handling of little shop assistants. Being of Irish decent, my small assistants are less likely to be moved by a plate of cookies but seem to appreciate a good Irish Whiskey. I don't allow that in the shop but I have been known to have a drop in the evening while sitting at the computer.  Their help is sometimes evident in the output of silly drawings.

There are thing that you can do and some things you can't do.
Don't worry about it. try it anyway.

I would not have attempted the lettering on the mill, like the track support lettering it would be done by hand with the high speed air rotary tool and dental bits. These letters are just too small though. I have sent the artwork off for a quote.
Keep an eye on your elves, drunk shop elves swinging from the chandelier can really make a mess!!

Got the recesses in the steam chest lids cut:

and cut the bars to length for the con rods and the end caps, then drilled/tapped for some 1-72 screws to hold them together:

Con rod blanks are ready for drilling and shaping...

And drilled/bored the big end bearing holes (will get bronze bearings in them)

then started drilling the other ends for the crosshead pins - using a bit of aluminum bar as a jig to get them all to match lengths easily. The brass bushing around the screw has a shoulder to hold down the part, and the OD of the bushing lower end matches the holes in the parts.

I meant no negative judgement. As it happens I have some alien DNA myself.
