Sidney Lathe Assembly

Added the saddle, apron, and headstock base.

The carriage is held to the ways by a small block bolted to the bottom of the saddle and bearing on the lower side of the ways.   The area resting on the ways is higher than the area bolted to the saddle.  There is play.   I'm wondering if this needs to be eliminated to prevent chatter.



According to Chirpy this does not need to be tight because the turning work forces the saddle down on this side.

Update: I may have had the plate positioned incorrectly.  I put it back on after taking these pictures and there is no noticeable play.

Mounted the backgear and spindle.

Snugged up the front headstock bearing without shims.  Used a drift in the back of one of the mounting holes and managed to turn off the face plate.  I will have to chase that hole but its not big deal in terms of lost thread.

The interior taper does not look good.

I'm about to where I need to start thinking about the motor and counter shaft.   A shortcut would be to temporally use the motor off the Jet dust collector if it would work.     Or maybe permanently.

Started on the motor today.  Got it taken apart.  Looks better than I expected.  Tomorrow I plan to wash the motor end covers in the heated parts was to degrease them.   The brushes stay with armature  Its a funny setup.  All the brushes are in one big holder.  It has a flat communicator which I cleaned with fine sandpaper.

Painted the motor yesterday.  From now on I will try to paint it after assembly.

Looked at the counter shaft.   Never seen a bearing tightened like this.   Backing them off allowed it to turn easily and the top half of the bearing I inspected looked good.





This is kind of interesting.   The felt wick of the bottom bea on the left soaks up oil from the reservoir on the right.

Played with the countershaft.  Had to add lead weights to the tower for balance.
