Most of the work has been done
... just finishing the boring job.
|
|
Hallowing out the box.
|
 |
|
 |
| Now the fun begins ... took a 1"
diameter 936 Bronze round stock sliced down the middle. These are about
5" long to make 4 sets. |
|
Finished the rough side and took
a little off to square them up a bit ... just not too much. Still need
enough material to get the 11/16" diameter flange.
|
 |
|
 |
Ready for soft soldering. Notice
that these little jewels are about 1 1/4" long, a little over the 7/8"
drawing. But I wanted more material in the 4 jaw chuck.
|
|
Squeezing out the excess solder
using a small press. The aluminum blocks are to help keep the bronze
somewhat square. The two pieces like to move around on the wet solder.
|
 |
|
 |
I melted solder on two surfaces before
pressing them together. This way I don't have to worry if there is
enough solder sandwiched between them.
|
|
Cleaned up the
edges a bit. Here I'm using a Co-Ax indicator to center the work pieces
in the 4 jaw chuck. This not a critical alignment, just want to be sure
there is enough material for the outer flange diameter.
|
 |
|
 |
| Another blurry picture. Glad I had
extra material as there wasn't much in the chuck. |
|
Here we have a bushing fixture
similar to a 5C collect. Brass round stock in placed in a 3 jaw, drill
and bored then it remains in the chuck for each bushing. Loosing the
chuck just enough to remove and install the next bushing.

After heating to melt the solder
then fine sanding and these bushings are ready to go. If you look
closely you can see the temporary black dots to identify the mating
pairs.
|
|
Thought I would add something new
... the colors are different so that the features can be seen better.
|
|
Although there is still more to do with these parts I'm well on my way
to start putting the Drive Assembly together. Soon I will have a
skeleton frame on some tracks. |
| Until Next
Time |
