The Corliss project

[lab-dad]

You guys are right.
It's been a crappy couple of months, sorry.
I have started on the new molds from stripwood.

Thanks for telling me what I needed to hear.

That's what happens when you get good.

Thank God your back, I was starting to worry about you.  The only thing you need to hear is get going and finish this beauty.

Marty ,

   Is there a reason why you made the concrete stepped ?  Although it is perfectly possible to cast concrete in the real World like that , it does make quite alot of extra work for no apparent advantage . Please tell as we need to know .

   Good to see you back producing , even if you do scrap it .

  So you've given up on doing it in brick ?

Thanks Nick,
It is stepped so I have a place to rest the floor beams (in addition to some posts).
Yes first attempt is sCRAPed.
Second attempt is drying/curing - (boy did it get hot!)
I thought of carving "bricks" but most of the examples I could find used a poured concrete.
The new molds are done with scale 2x8's as forms.
Hopefully I can take a pic this evening.

better?.................


there are some air holes(not too bad for the size)-its 3 3/4 square and 2 1/4" thick, may be I can disguise them?.....

Any suggestions for the basic coloring (I usually use Silverwood) and then some grease/oil stains.
I'm also thinking some rust where it would likely occur being many parts are cast iron.

Much better!

I would not worry about the air holes at all. Very often you see cavities larger than those in prototype concrete work.
Here in Norway the builders (and pissed off) architects call them "Steinreir" wich means "Rock nest" or "pebble nest".

They occur when you do not vibrate the poured concrete properly, the aggregate (usualy gravel) clumps together and makes pockets of air/gravel. I guess Marc know the proper terms in english!

Marty I agree with Havard...no problem with the holes....you could even accentuate/detail them a bit....I do this on my castings by stippling with the Micro-Mark wire pencil.....try it on a test piece first though.






Here we (at least I) just call it a "shitty pour" and unacceptable  ....I actually rarely run across these in this day and age......maybe because the contractors I work with know what an ass I can be in the field when stuff like that happens...and it usually ends up costing them......so they try real hard not to have them.

 Marc ,

   Yes , I can imagine you could be a pain in the ass to work for !

 Marty ,

   Significantly better results . I bet you feel happier now ,

I thought some might find my mold design of interest.
Basically 1/4" poplar with 1/4"x 1/8" planks glued to it.
Does require a little calculating before any cutting though.
By having backing sections (in this case cheap hardboard) the mold stays square.
I tape it all up and use clamps to keep it that way.


And the foundation;


I just realized I need to make the tall one for the large pillow-block too.

Nice mold and casting. It's coming along splendidly.

  This looks a lot better.
  Take in account that cast iron is corroding far less than steel. A bit surface rust........Don't overdo it as these machines were normally placed in well build enginehouses, not much change of condense etc.
