I purchased on of these brass and cast metal kits that uses a Bachmann HO 0-6-0 mechanizim.
I used the etchings that make the cab and saddle tank but will not be using the cast metal details.
I have some PSC details I may use and have been building the others from scratch.
Obviously these are "in progress" shots

Is that a Backwoods kit or from another manufacturer?

Good looking engine Marty!

This is a fine model and it will be even more interesting to see some extra details added.

I have a Backwoods brass kit (climax) sitting here in the box, so any hints on working with the brass would be most appreciated.

Nice new project, Marty. I'll follow with interest and pleasure the machining of the various domes so as they fit the boiler curvature.

Gee, I hope that is the BWM kit Marty.

I just purchased one and have yet to open the box and niff around it, and your looks fantastic!

Now I have to go look.

I decided to build the Boxcab conversion from them first.

Can I ask why you decided to go with the PSC detail parts over those from the kit?

Great work, keep the updates commin!

Thanks guys!
Yes it is a Backwoods kit (they dont pay me to advertise) :D
Anyway,
I chose to use the brass pieces over the kit pieces as the pot metal (or Cero, or whatever)
is not really round and clean.
Then again neither is the PSC castings.
The PSC sand domes are not round enough, or the filler holes straight enough to allow mounting
in the lathe for truing or drilling for mounting hardware.
As for machining the radius on the dome bases I am going to try a flycutter in the mill.
Mounting the dome in a fixture sideways should do it (ordered the fly cutter today)
If the steam dome works I may try the sand domes.

Larry,
Working with brass is easy.
I always solder, it is bullet proof!
Most guys use too much solder, I only use what will stay on the end of a iron.
I have the Radio Shack 20/40 watt iron for most things.
Larger pieces I use a micro torch on.
Also clean, clean, clean.
Most of all a little paste flux (not too much)
Try some scraps from an etching and see how easy it is, clothes pins and
metal blocks make great soldering fixtures.

I also use a piece of black marble tile 12" x 12" to solder on.
Hope this gets some of you started on your brass project.

Well the flycutter came yesterday! (Ordered from Sherline Sunday night!)
So I set up to cut the radius on the steam dome.

First off;
How to set the cutter to make a .750" radius cut? (1.5" diameter)
I thought about a dial indicator, but how to "read" the backside?
So I checked with my caliper and set it a little smaller.
Then I put a scrap in the vise and made some test cuts, eventually I snuck up to a diameter of 1.495"
I had to trim some of the back of the cutter so it wouldn't hit the workpiece.



I decided I didnt need a "jig".
I just mounted the rotary table on it's side and put the 3-jaw chuck in it.
I wasnt really sure how to make sure it was all lined up on the centerline so what I did was put a .032"
music wire in the chuck and a .032 bit in the mill.
Even so I guess the cutter is slightly offset, so I had to move the table back .005"



And the final pass!
The fly cutter cuts great! I'm really glad I needed it!
I ended up moving (or removing from) the dome .025"



I think I did pretty damn good for a first time!
Now for those sand domes that look like turds........



Hope you enjoyed this.

Hey Marty,

Thanks for the step-by-step with the milling process; very informative.

I have been interested in getting a mill and lathe, but I can't yet justify the cost; especially when I don't know how to use one.

So thanks for providing a perfect example of the use of one!

BTW: I too have the same Backwoods Miniatures 0-6-0 conversion kit; it is still in kit form.

Thanks for sharing; looking forward to your continued postings.

Marty, Very nice. Dumb question, what is the piece in front of the dome with the ring through it? I've never seen that before. Roland
