Re: Reset needed to restore power [2 Attachments]

Hello John,

Thank you for the response. I was suspecting a thermal issue based on what I've seen. Your message confirms that may be possible.

I have been unable to find a part number or any documentation on this that would help lead me to an adjustment, or a replacement if something is wrong.

Also, if anyone has a 10k with the stock 1/2 hp 3 phase motor it would help to know what current it draws.

Thank you,
John

Francis Tuttle Technology Center in Oklahoma City. North-West side of town. South-West side of town has Moore-Norman Technology Center. The precision manual machining class cost $1800 last last I looked. The CNC machinist class, which includes the manual machinist class was $4200 IIRC. Don't know how much the course(s) cost at Moore-Norman.

As for justifying, SWMBO has her own little list of things she thinks we need around the house. Gotta give her priority once in a while. Besides, she has let me buy two lathes, a mill, and a shaper in the last few years. Plus a lot of stuff I need for them. She also encouraged me to take the class. I have no complaints. :)

Bill, where did you find
a school that teaches machining? I have been looking for one
for a long time. By the way, I don't think you have to
justify buying a super precision, beautiful tool that will
last you the rest of yours and your children's lives if
taken care of. If you can afford it, buy
it.

Hi, contactor on the left,

this acts as an adjustable fuse,
can it be set, a shade higher, ??

On my South Bend 10k the power will randomly shut down and a reset is needed to restore power. I'm looking for ideas on what might be causing this.

Current consumption is 4.6 Amps while turning and does not increase when the lathe shuts down.

I am using a 5 HP rotary phase converter which is unaffected by the shut down.

Re: Inspection thoughts?

glenn brooks <animalbrakeman@...>
 

I keep a gallon of diesel , some paint thinner, and a gallon of Evaporust around the shop to clean my lathes and mills - load the diesel a quart at time in a laundry room plastic spray bottle.  Squirt a little on your dirty/rusty surface and scrub down with shop rags, an abrasive green sponge, or the occasional LIGHT use of 600 grit wet dry sand paper for difficult  rust spots. A quick overwipe with paint thinner cuts the excess diesel if you want to get rid of residue.  

Also you may look at cleaning the ways with Vactra way oil to remove all traces of the grey slurry that comes out from under of the saddle onto the V's when you first lube it.  The grey colored oily smears  are composed of minute metal dust picked up by the way oil, and caused by the saddle wearing against the ways.  This grey slurry acts as an abrasive and eats into the matched surfaces as your saddle travails back and forth.  A lot of people in industry clean this stuff religiously off their machines. Sometimes takes four or five cleanings in a row to see clean oil roll out of the saddle .  But it's worth it.

Afterwards I always coat all the bare metal surfaces with way oil.  It collets dirt and grime from the air, but is super good at protecting the surfaces.  Just wipe off and recoat each time you use the lathe.  

Sounds like you will be getting a very nice, tight machine!

It was as advertised. Picking it up Saturday. Busy making room in the shop (basement) for it, as it is quite large. The apparent corrosion on the thread dial was an anomaly in the photo, no corrosion on the dial at all.

A lot of the paint shows cracks and much of it looks like it will flake right off. Any thought on repair? I certainly don't need/want to repaint it, but would like to get the built up dust off of it without doing any additional damage.

Anyone tried electrostatic paint? Years ago I watched a guy paint some office furniture with it and was amazed at the quality of the paint job and the almost non-existent overspray.

Surface plates Re: Newbie (New Member, New to me South Bend)

Gregg Eshelman
 

Cast iron gets used for high precision surface plates. In 2014 a huge one made by Gorton for use in their factory was sold on eBay. According to the data plate on it, it took seven years from casting through various stages before their craftsmen *started* the final scraping step. That master plate apparently became the foundation for all the testing at Gorton, possibly for the rest of their existence.


Dunno if the person who bought it hauled it the 420+ miles home or if the museum in Racine, WI accepted it as a donation or loan.

There are 3 issues here, which should not be confused with each other, namely mass, stiffness and damping.

If something rings when you hit it, it doesn't contain much damping.  If it just goes thud or squelch, it has lots.  Concrete damps much better than steel, as, incidentally, does cast iron.  All 3 together can help if your machining problem is vibration.

If your machining problem is persuading your machine to maintain alignment despite a built in natural tendency to do otherwise, then the only necessary parameter in its mounting is stiffness, so it can be forced into shape rather than it forcing its flimsy foundation into its preferred shape.  Beware wood, as while it is thermally stable, its shape changes with humidity, to quite a significant extent, so it and high precision are mutually exclusive.  To be honest, for a hobby lathe, a rectangular framework of substantial angle iron, having diagonals in both directions in every plane, attached close to the holding down points for the machine, ought to be stiff enough to provide the required result.  I would recomend bolting rather than welding, as welded articles change shape over years due to their working stresses stress relieving the welds (unless you have a big enough and hot enough oven in which it can be stress relieved!).

Granite (the type of rock does matter) is used for high precision surface plates as it is more stable than the common alternative, cast iron.  It can also be used for the guide ways of the sorts of machine tools that are part of a building.

Re: Newbie (New Member, New to me South Bend)

Bolt the headstock end down snug then check to see which side of the tailstock end foot is not touching the benchtop. Put shims under that side. Making sure the bed isn't twisted is easiest if it's level - but with a precision level you can adjust the shims to get the same amount of front to back tilt at both ends.

An option some years on the 9" Workshop (and others with the bench mount option?) was an adjustable tailstock end foot. The procedure with that one was loosen the adjuster screws, bolt both feet down snug then use a level and the adjuster screws to ensure there's no twist in the bed.

Thanks Ed! 

I have read that adding a concrete base to an existing table was a recommended solution for these smaller lathes such that they could more easily build high tolerance parts for the war effort. A 3" thick concrete slab and a 1" steel plate weigh about the same. I don't know which I worry about more... my ability to pour a flat slab on concrete or prying my wallet open enough to pay for a 1" thick slab of CRS!  :)

If the table top is not nice and flat, what is the procedure for leveling, or mounting the lathe so that bed twist is not an issue?

Thanks for the suggestion!

Re: headstock stock run out?

Johnny,
Do not worry about having taper in your piston.

Real pistons are tapered and are barrel shaped. They DO NOT have a true cylindical shape. Generally, the bottom of the piston has the largest diameter, though it isn't truly round.

Normally I wouldn't worry about a .0005 tolerance. However,
the plans for the  small IC engine I am building call
for the piston to be no more than .0012 smaller than the
cylinder. With an inch and a half long cylinder, a .0007
difference in diameters to start with seems to be too much.
 
  Please feel free to correct me if I am missing some thing
here. I am teaching myself and can use all the help I can
get. Thanks

Another suggestion if you have some time...

Search Craigslist ( Both local and around the country ) for a machinist who is retiring.   They usually have excellent equipment and have taken great care of it.  They are looking for someone who is willing to pay more than import prices for items.  Also they are usually willing to make a better deal on a "bundle".

Nice bench! It looks very sturdy. The one leg under the "tail" seems somewhat unique. The vertical space for the chip tray seems generous.

After checking out the net for information on the AXA Multifix. Decided to buy a AXA Multifix Type A including 4 holders, made in Germeny, no Chinese copy. It came in last saterday and after some modifications it fits the original toolpost. So now both type toolpostholders can be used on the lathe.
