There are other ways to mound a spindle motor on your legacy I chose the swing 
away type with

A gear, this when incorporated with all the different legacy gears gives a 
greater range of speeds with the variable speed gear motor from very slow to 
quite fast.

Thank you for all the valuable information that you have been providing over 
the many years.  I'm a new Legacy Mill owner and have learned a lot by reading 
your posts.  Thank you.

 

I have some question for Curt George, but anyone can chime in and share their 
thoughts.

 

Over the last two months, I have purchased two Legacy mills, one model 1000 
(used but in great condition with lots of gears and goodies) and one model 1800 
(a brand new 2004 model, still in its boxes).   

 I'm in the process of putting together the 1800.   The tip on the grooved rail 
will help ensure that I do it correctly.

On the Legacy model 1000, my first upgrade is replacing the plastic bushings in 
the headstock and tailstock with ball bearings. 

Curt, referencing your YouTube video on the "Spindle Drive Modification" 
<https://www.youtube.com/watch?v=SXCC-EolhjQ>. 

I’m impressed and understand your video description and demo of the spindle 
drive.  I would like to incorporate this upgrade into my Legacy model 1000. 

 Questions:  

On the DC drive motor, what brand, model and torque value and speed would you 
recommend? 

On the DC motor controller what brand and size would be best?  

Would a reversible controller and motor have an advantage? 

Another option to achieve variable speed and direction control, would a 3-phase 
motor and controller.  Would that be a good choice?

Curt, on a side note, I started collecting and using Shopsmith tools about 6 
years ago.  I also noticed that you have Shopsmith tools in your shop.  I took 
note that you had successfully adapted Shopsmith parts to your legacy – great 
job! 

 I agree with your encouraging viewers to explore their imaginations without 
limits. 

 VR, 

Nathaniel Bacon
