Hello All… This is my first post to the Logan section !!!
I am a new Logan 820 owner, Serial # 40926, born in 1946 !! I purchased this machine….Rebuilt. It is not in "museum condition"….but very nice !!!
A few… Idiosyncrasies……Chip pan is backwards, Forward/Off/Reverse switch wired backwards, missing Holding bracket for Headstock Cover….and a problem with the Friction Clutch.
Locking wheels are great to move the Lathe around....BUT....I will likely migrate to the " Hockey Puck " design feet in the near future for most accurate leveling !!
I have had a chance to start to learn the machine. My neighbor( Paul) is a retired machinist….and a great Mechanic / Machinist. He has taught me MANY things….and is most patient !!! I am very grateful !!
In his opinion....which I trust completely.....Ways are great, Headstock was rebuilt ( New bearings), Run-out checked and very good…..+/- .001 @ 12”. Original 3/4 Hp motor - 110 VAC. QCGB all working good and Lead screw good.
SO....yesterday......we just fixed the Friction Clutch. How fortunate it was a simple fix !!!!! The Clutch knob would NOT engage….Cross direction or Longitudinally.
I searched the forum….and found this…….

Thank you 58A !!
So….we open the Apron Clam Shell up…..Note, Handles can stay attached….just remove ALL bolts you can see.
All gears are in great condition….including the Half-nut !!
We only found that one ….. of the two….very small springs in the inside of the clutch unit had fallen out….and would prevent the clutch washers from compressing properly !!!
SO….put the spring back in….cleaned up the Clam seating lips, applied a very thin layer of GE Silicon Sealant, bolted the Clam Shell together, mounted the unit back to the Lathe and reconnected the Lead Screw end clamp.
Note: One must remove the Lead Screw clamp to slide the Apron assemble off the Lead screw. Used 80W Gear Oil to refill the Apron reservoir.
Works perfect !!! Paul is a genius….and this forum is of GREAT HELP !!!! THANK YOU !!
SO….sorry if I have failed to us any correct names…..I am new to this Lathe Repair business….and I am sure I barely qualify as an Apprentice Machinist….BUT….It is a great feeling to keep this vintage machine ready….for another 73 years of duty !!!
I am very glad I opted for a vintage unit....built like a tank....and with good tolerance....and...it just seems right to give this lathe TLC and more opportunity to continue to machine with purpose and pride.
Just thought I would share my joy and experience !! I did not want another hobby....but am oddly attracted to this passion !! I get it !!
