Well i got it guys.
There is using brake clean and there is USING brake clean! :big:
Seems spraying it directly on it vs a wipe rag did the trick.
Frame #1 is completed and shining nicely.
On to Frame #2.
 
Today I tried a new piece of software, the Alibre Cad and Drawing software.
It worked very well and was extremely user friendly.
I was able to create the frame end brackets and make a nice drawing for shop use.
 
Well I finished up the frame rails today.
Feel good to get through that first one without any real issues.
I even have me original drills and tap! ;)
On to the End Sill Brackets next.
 
I have started to mill out the 3 flat surfaces which will mount the end sill bracket to the end sill. The original plans call for this to be a separate piece soldered to the bracket. One nice thing with a mill I can just mill it all from a solid block saving the soldering step. I also allowed my Visual Mill 6.0 program to choose the feed and speed for this operation. I must say I was somewhat surprised at how slow it set the rotation speed. Just 267 rpm. I had it setup to cut .01 deep cuts. It cut perfectly with nice small chips and no smoke. Posted below is the feed and speed setting for this cut on 304 stainless steel with a 1/2" HSS End Mill.

The second bracket seems to have come out just as expected.
It also fits pretty darn nice to the frame rail.
Oh, and I have since came to my senses and am cutting in a vise now instead of the hold down
clamps with such a small part. :p

 
After a long break with this project I have picked it back up and am hitting it hard once again.
With the Frame Rails completed I worked on completing the End Brackets next.

The coupler Draw Heads came next.
This was by far the trickiest CNC work I had done to date on this Loco.
They came out really cool looking.

Here is the Base Plate.

Last night I completed work on the Hand Holds which are mounted to the top of the End Sills. This would be my first bit of soldering on this loco.
Being that I will be using a great deal of stainless steel and brass, I had to find the right kind of solder to do the job.
I finally came upon the Muggyweld SSF-6 flux and solder rods.
This stuff works great.:D

Here is a shot of the end of the hand hold soldered to hand hold base.

Good to here your back to the loco. I love watching the loco builds.
