    Default Making a rotary vane compressor

    This is the first episode of a video series of making a rotary vane compressor.

    In this video I am using:
    - Weiler Matador SV (1972) Lathe
    - Schaublin SV-51 (1955) Milling machine
    - Solberga (1975) Drill press

    Thanks for moving the Video to here.
    I did not notice earlier that there was this compartment for videos.
    So now I know

    Default Making another part for the rotating vane compressor.

    This part includes a precision hole for the bearing bushing.
    I fail with shrink fitting the bearing bushing but succeed in rescuing it.

    In this video I am using:
    - Weiler Matador SV (1972) Lathe
    - Schaublin SV-51 (1955) Milling machine
    - Solberga (1975) Drill press
    - Wohlhaupter UPA3 Boring/Facing head
    - Tapmatic 50X Tapping head

    Default Making a fairly complex part for the rotary vane air compressor.

    This part has three precision recesses which will be done using the Wohlhaupter UPA3 boring/planing head.

    In this video I am using:
    - Weiler Matador SV (1972) Lathe
    - Schaublin SV-51 (1955) Milling machine
    - Solberga (1975) Drill press
    - Wohlhaupter UPA3 Boring/plaining head
    - Tapmatic 50X reversible tapping head

    Default Making gear pump gears for lubrication system

    Since the vanes of this compressor will be made out of steel, some lubrication is needed.
    There will be a gear oil pump that forces the oil into the blades and also pushes the vanes against the cylinder walls hydraulically.
    Two identical precision gears are therefore made.

    In this video I am using:
    - Weiler Matador SV (1972) Lathe
    - Schaublin SV-51 (1955) Milling machine
    - BS0 Dividing head

    Default Testing the oil pump.

    There are quite some silly animations. Enjoy!

    Default The Cylinder

    The cylinder of this air compressor must be quite accurate.
    I am using my Bison 250mm 4-jaw chuck to turn this cylinder.
    There is a lot of metal removal and problems associated with it.

    Drilling and tapping holes to the ends of the cylinder.
    It is a rather simple task but having them in a perfect bolt circles that are aligned between the ends is no more a simple task.
    Tapping 16 blind holes to 20 millimetre deep M4, that is not a trip in the park either.

    In these videos I am using:
    - Weiler Matador SV (1972) Lathe
    - Schaublin SV-51 (1955) Milling machine
    - Solberga (1975) Drill press
    - BS0 Dividing head
    - Tapmatic X50 tapping attachment

    Default The rotor

    This time it is the rotor.
    It is made out of 50 millimetre cold rolled steel.
    There will be precision turning and eliminating the taper.

    - Weiler Matador SV (1972) Lathe

    Default How to make six grooves 3 millimetres wide and 15 millimetres deep?

    You could try to make those with an endmill but since the grooves are 100 millimetres long that would be a major PITA to pull through.
    The obvious answer is, of course, the humble slitting saw.
    Traditionally I have had no luck whatsoever with those and usually I end up collecting slitting saw shrapnel from my floor.
    It will be very exiting to see what is the outcome this time.

    Default This time it will be the lamelles for the compressor.

    There are 6 of them and they are made out of Uddeholm Vanadis 4 tool steel.
    This steel is quite tough to machine and there are also some challenges with setups.
    I will also get a stopping reminder why safety goggles are a must.

    Default This time it will be another steel puck for the compressor.

    This time it will be another steel puck for the compressor.
    There will be a precision recess for a shaft seal.
    I will be using my Wohlhaupter UPA3 boring head to make that one.

    - Weiler Matador SV (1972) Lathe
    - Schaublin SV-51 (1955) Milling machine

    Default Will this compressor become silent?

    Air enters and exits the compressor through holes in the cylinder walls.
    I machine flats on cylinder sides and holes for air flow.
    Then I put the thing temporarily together and test it.

    - Schaublin SV-51 (1955) Milling machine

    Default The output manifold is just a block of steel with three holes and a recess.

    Although it is so simple, I manage to make a major mistake with it.
    I am lucky enough to catch the mistake in time and take corrective actions.
