Up next on my "to do" list is the drill press.
The one I am building is based on the CHB (now Sierra West) Camelback version with auto feed.
You can see the SW one here; http://www.sierrawestscalemodels.com/oscale/machine.shtml
For reference here is a picture of a real one;
Mine will have the gear operated auto feed not belt driven as shown in the reference image.
The big(actually just one of them) challenge was the column.
It needed to be 9/16" at the base and halfway up taper to 5/16, then a 90 degree bend.
Easy.....
Here is the brass rod (solid) on the lathe being tapered;
Once the taper was complete I heated it to anneal it (make it softer) and put the bend in it.
Here I am attaching the upper bearing guide.
The base was milled from .250" aluminum plate.
I needed the weight to keep it from tipping over, that column is heavy!
The collars for the table support are aluminum and the arm is .250" thick flat brass.
The table is three layers of styrene.
This allowed me to form the "T" slots accurately.
Here I am milling the through holes in the table after I turned it round on the lathe.
And here is where I am at currently.
More soon.

Well Mr. Jones I see your making progress on the Drill Press.
I guess I will have to go on line and find you something hard to do.
As always you don't let us down. Your machineing skills are unbelievable!!

Working on the automatic feed gears.
There are 11 gears in the picture below, the squares on the mat are one inch.
The shafts are .062" for reference.
Sure was fun calculating the shaft locations and fabricating the jig to align everything.

Working my way through the gears.......
The auto feed is some fiddly stuff.
I keep thinking to myself "how the hell did Charlie (Brohmmer) do this in "O" scale!!!!
I have since moved the parts a little and decided on a smaller driven gear.
Turning down the cast one in this picture was sure a challenge......Oh well.
More soon.

Sure does look like Charlie's. Excellent job on the gears, Mr. Jones.
Maybe you should go into business selling these little gems.

Had to get some color,finishes, pigment on the pieces.
Also moving along.
Some minor bits to add to the table lift (I'm getting tired of using tape to hold it up!)
Also the lower quill gear can not be secured until final assembly.
I am especially proud of the hand shaped handles on the table lift crank.
More soon!
Thanks for looking!

Looks really excellent with some color on the gears.
They really stand out now.
