Gear Reduction System #GR #MODS


 

Greg and members, Ref you tube postings.
Just doing a spring clean on my computer and found this.maybe of interest.


This was me machining more gear reduction motor mounting brackets for Real Bull lathes, Sietg have?
different type motor end plates, but Robert Furmanak of Florida owns a Sieg mini lathe and had? good success with his design many years ago.
Video : Expanation, an aluminium billet boled to a face plate, 25 mm eccentricity, 3 mm deep cuts.80 mm final diameter,?using my 2:1 reduction ratio. GR now double the torque with a loss of almost 45%of top RPM.
Max RPM of the Real Bull from the factory 2500 RPM, Crazy speeds for a metal turner like me , or even wood.
machinst, 100 mm chuck running at 2500 RPM, IMHO, not safe.
So far, I have supplied a total of 6 gear reduction units worldwide for Real Bull lathes, all seem happy?
campers in its use.?
More info is available in the digitalhobbyist forum under hashtag #GR
Naturally my first prototype motor bracket was machined with the original power supplied from the factory supplied lathe, what a SLOW job that was.
Hope of interest, and inspires forum members of future projects.
Regards
John Lindo
