Tailstock alignment and Dead Center

To align the tailstock we need to know the exact center of the headstock.   This is done by turning a  60 degree taper which can later be used as a dead center.  A pin with threads in the printers junk was used.

In these images you see a smooth center and a rougher one.   The smooth is in the tailstock, other in the headstock. 

The left image, with the dial showing, is taken from the top and illustrates the left/right alignment.  This is easily adjusted with two bolts on the tailstock.   Mr Pete shows a method using a dial indicator mounted in the chuck to check the center in the tailstock.  The plan is to use this to further refine this alignment.

The right image is taken from the side and illustrates the up/down misalignment.  Luckily the tailstock on the left is lower than the headstock and can be raised with shims between the two halves of the tailstock.  The 'interesting' part of this will be getting the tailstock quill in line with the spindle.  If its skewed it will make drilling difficult.

Lathe Installation

I calling this lathe installation because the lathe is moving to its working location and hard wired to the buildings electrical system. 

The motor is on the tower and the tower is bolted to the wall with one bolt.  Need to see if I need the 2nd one and then figure out how to make that happen.

The plan is to use 1/2" thin wall  metal conduit down the wall and under the lathe then up to the drum switch.  Run the switched wires back up the same conduit and into the box then small armor cable to the motor.   That should be a 'fun' bit of conduit bending.   It has to clear the edge of the chip tray (in case I get it installed later) and drop to go under the lathe bed then a 90 up to the drum switch.

Need to add images here.

First chips on Tuesday.  Faced the hub on an old aluminum pulley.   The bit was one I just picked up.  I'm sure it could use sharpening.

Created a casting pattern for leveling feet.  It will also raise the lathe to a better working height.  I'm not sure if it is smooth enough to pull from the mold.   The paint in the images is wet and it may look different when dry.

Lawn and Garden Tractor Update

Removed the JD111, JD160, and the old Murray 11HP with no rear end from the van truck. I pulled the motor from the Murray 11HP.   I think it will go into that strange Murray that shoots grass out both sides of the deck.    The DYT4000, LT1000(2) and the Murray with the Brigs Oppy went into the truck.  No point in having good tractors outside and junkers inside.  Need to figure out a better outside place to store the JDs.

Was gifted with a Cub Cadet ZT.  This is the one I worked on several times.  After I put a new PTO clutch it developed other hopefully minor problems and the owner just wanted a new one.  I tucked it under a 1000 poly tank for the winter.  Not sure what I'm going to do with the thing.  Its a nice ZT but I really have no use of it.

Shop Wiring For Lathe

The plan is to setup the lathe motor for 220V and piggyback it to the breaker connect to the round outlet on the bottom left of the box, that I have yet to use.  The wires will use the conduit on the upper right which is empty.

The image below did not come out well.  IPhone X camera was having fits.  The conduit to the right of the first connector was already in place.  The next two bits and the box were added.  It was easier to use 2 sections for the double bend on the left side of the post.  I'm still debating on what plugs and sockets if any will be used.  Not much of a down side to hardwiring it.  Maybe even drop conduit out the bottom of the box and have it connect to the drum switch.  Need to see if that makes sense.

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.

January 4th

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.

January 5th

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.

January 7th

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.

January 9th

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

Sidney Lathe Assembly Begins

I have been somewhat negligent in keeping up the blog.  Most all the parts are cleaned and painted.  The quick change gearbox needs more cleaning and paint.  The lead screw needs cleaning and maybe paint.
