Ty's HF 7x10 Mini Lathe Page

This is my SMALL machine shop.

I own a Central Machinery ( Runmaster) 7x10 Mini Lathe, and a Sherline Model 2000 Vertical Mill.
I purchased both items with the idea being that if I didn't like, or couldn't use them well,
that I would not have THOUSANDS of dollars tied up in them. I have found that I can pick up
a new skill very quickly, and currently am building an arsenal of tooling for both mill & lathe.

Front of the 7x10

Left Side of the 7x10

This is a nice lathe within its limits. It is called a 7x10 but, the maximum you can turn with this little jewel is around 3" ( with the cross slide under the workpiece that is...). It can turn a piece just under 10" or so in length. I have found this lathe to be a real joy to use, and am getting really comfortable with the idea that there is probably nothing I cannot make with it ( within its size limits of course ).


What my 7x10 came with:
  • A 4 position toolpost. ( Capable of holding up to 5/8" Tools. 

  • My center height is dead on 5/16"above the bottom of the tool holing area.)
  • A Live Center. MT#2 
  • A Tail Stock ( Adjustable ) Bore is MT#2. 
  • Two combination wrenches 8mm-10mm, 14mm-17mm. 
  • Assorted Metric Allen wrenches. 
  • A plastic oil bottle. 
  • 3" 3 jaw chuck ( Self Centering ). 
  • A Fair Manual. ( Images Muddy & Dark, But Good Info.) 
  • A set of change gears for 26 different threads.
