I acquired this micro lathe in March 2008. This little machine is UNIMAT, model DB-200 and was made in Austria back in 1950-70's.
Here is nice web site describing history of this little gem.
I will be adding pictures of attachments that came with the lathe as well as drawings of attachments that I am planning to build.
ELS - Electronic Lead Screw
This is a very valuable addition to the micro lathe.
Developed by John Dammeyer (more info on his web site
) it provides
many capabilities found on large lates. With the ELS, you will get ability to cut ANY thread (imperial, metric, special...)
but not only that, you will also get the following:
- SFM read out
- power feed for Z and X axis
- DRO for Z and X axis
- ability to cut precise tapers
- pre-defined tapers:
- Morse taper #0, #1, #2, #3, #4, #5, #6, #7
- Jacobs taper #0, #1, #2, #2A, #3, #4, #5, #6)
- IT taper, ER taper, R8 taper, 5C taper, 3C taper
- rapid traverse for Z axis (i.e. when you need to move tool away for measurement)
Below are some pictures, of my implementation on the Unimat as well as drawings of parts necessary to do the modification.
This is still pretty much work in progress, I will add more and better pictures as I progress.
UNIMAT - Power feed with a stepper motor
Bellow is a picture of possible arrangement with a stepper motor mounted behind the lathe
OCLE - Oscillating column engine
I am planning to make detailed set of drawings for this engine that can be made on Unimat.
It is based on the drawings for River Queen OCLE engine published in the Edelstaal Technical Institute Booklet No. B-100.
Two Cylinder Vertical Steam Engine
This model is based on the article by C.W.Woodson, published in January 1953 issue of Popular Mechanics Magazine
Single Cylinder Horizontal Steam Engine with reverse
This model is based on the chapter 43 of Elmer Verburg's book Elmer's Engines
