Re: metric gear help

got it sorted. the lead screw gear must mesh with the 63-tooth gear on the 80/63 gear set. the 80 meshes to the 32-tooth spur gear


Re: metric gear help

sorry south bend 10k lathe. half nuts and not running the machine. spinning by hand as it is a very short 1/2" of threaded area


Re: metric gear help

mike allen
 

        Hate to ask a stupid question , but are you using the clutch or the half nuts ? What lathe , 9 , 10  or larger ? If you go to the  files section for  the group & use the search in the upper right

        for metric you will see several things for metric threading .

Sounds like the worm drive key is riding out of position when the saddle is moved, I had a similar issue with mine after stripping it to install new felts, you can check this with a torchlight and see if it jumps out after moving it, if it jumps out it will allow about an inch of movement until it jams up.

Re: Two and Three Point Steadies

        Depending on the size of the car that the rotors came off they should make a good steady . I've been thinking about getting one from a small car to use for a base for a micrometer stand . Good

        luck with that project & keep us posted on the project . These are the kind of projects I really like then ones that are way , way out of the box !

That sounds like a good idea. I was at a Ford dealership about a month ago and saw two late model rotors in the trash. They just looked so useable for something that I asked if I could have them.. I’m thinking that they would make great repurpose as a steady.  Especially since I think the rotor has a stamped steel center and cast iron brake friction surface. Remove the stamped steel center and it’s almost good to go.  

  Anyway, great idea.

I am thinking of using maybe a 1 ton truck disk brake rotor to do something like this.
Has anyone seen this done before?  The rotors are cast iron and very strong.


Re: South Bend Fourteen Lathe Drive Belts

Mark R. Jonkman
 

The south bend fourteen doesn’t use flat belts. It has a Reeves drive for variable speed and a main drive belt that I believe is like a timing belt on mine. 

Completely different beast then 9,10 or 14.5” lathes.

I know I will have to remove a pulley to get the belt on/off. What else should get inspected? My Clausing has fiber bushings in the pullies, I will check them. Drive isn't making noise, so I expect they are OK. Mostly looking for the "gotcha" items, i.e. special tools, hidden setscrews, etc.

Thank you for your help.
It is dual V-belt. 
Ted says he has them and also provided cross reference to current parts.
We may get my friend's lathe fixed.
Having a lot of slip in high torque operations, i.e. drilling large holes, etc.
Tried retensioning the belts, but no real improvement. I suspect the problem is the Vari-Drive belt, rather than the spindle belts. 
The original owner says they have never been replaced.
Either way, we will scuff up the pulleys, replace the belts, retension and giv'er a go..

Well, I may have looked at the wrong part number.
I show the timing belt as PT4456TT1, but I believe that is the single drive belt on the post Nov 1974 up.
I don’t show the number you listed, does it have dual drive belts?
I looked in the older parts list, and the AC dual drive belts match the number you list, starting at about SN 73TT876.
That belt is 66.93-inches.

Hi Derrick,
If anyone might have them it would be Ted…
The part numbers you list are for a November 1974 forward, starting about SN 74TT1260.
The variable speed belt is a Speed Selector Inc. belt # 2322V421
This belt is still listed in their belt catalog, but not sure with out calling.
I believe the variable speed belt is the same as the older 14’s before the above date.
The timing belt is a Browning 660H100
The timing belt is not the same as the older belt.
You should be able to cross the 660H100, I see them listed from 13.00 to 106.00
That belt is 66-inchs x 1-inch
I don’t know the length of the VSD belt, only that it is 10.5-inchs center to center.
The Speed Selector price list as of 4/22 lists the belt at 54.00.
 
Hope that helps,
 
Steve

On my SB 9” lathe, the taper attachment has a locking nut that engages it and also another screw which much be removed whenever I use it. I remember that I once had both the taper engaged and the other screw in also. It locked the carriage up in a similar way you describe.

Why not take your motor to a local electric motor repair shop and ask them for the correct key?  They should have them by the batch for el-cheapo prices.

Hi,

Does anyone know the correct size of the woodfruff key that locks the bull gear to the spindle?

I'm a child of the metric system and when i measure it with guessameters I don't seem to fall on a standard size ("standard" as in what I can fond on ebay)

Thanks in advance.

Make sure that the taper attachment locking nut isn’t engaged. On my SB 9” lathe, the taper attachment has a locking nut that engages it and also another screw which much be removed whenever I use it.

Thank you for your help.

It is dual V-belt. 

Ted says he has them and also provided cross reference to current parts.

We may get my friend's lathe fixed.

Having a lot of slip in high torque operations, i.e. drilling large holes, etc.

Tried retensioning the belts, but no real improvement. I suspect the problem is the Vari-Drive belt, rather than the spindle belts. 

The original owner says they have never been replaced.

Either way, we will scuff up the pulleys, replace the belts, retension and giv'er a go.. 

Thanx and Good Shootin'

Well, I may have looked at the wrong part number.

I show the timing belt as PT4456TT1, but I believe that is the single drive belt on the post Nov 1974 up.

I don’t show the number you listed, does it have dual drive belts?

I looked in the older parts list, and the AC dual drive belts match the number you list, starting at about SN 73TT876.

That belt is 66.93-inches.

Hi Derrick,

If anyone might have them it would be Ted…

The part numbers you list are for a November 1974 forward, starting about SN 74TT1260.

The variable speed belt is a Speed Selector Inc. belt # 2322V421

This belt is still listed in their belt catalog, but not sure with out calling.

I believe the variable speed belt is the same as the older 14’s before the above date.

The timing belt is a Browning 660H100

The timing belt is not the same as the older belt.

You should be able to cross the 660H100, I see them listed from 13.00 to 106.00

That belt is 66-inchs x 1-inch

I don’t know the length of the VSD belt, only that it is 10.5-inchs center to center.

The Speed Selector price list as of 4/22 lists the belt at 54.00.

 

Hope that helps,

 

Steve

Working that as a backup. I tried to find mfg and numbers on old belts but they are gone. Found a guy (TED PFLUGNER (latheman2@...) that says he might have them. Mostly I was hoping someone in the Forum had current P/N's. I will post results if I can source them. 

Thanx and Good Shootin'

Do you have the original belts? Can you take measurements off them and look them up from there? I have a south bend fourteen though right now it’s in my son’s shop about 20 miles away. If you need measurements and ain’t in a hurry I might be able to measure them.
