Reminder To All SBL Group Members

The FAQ will answer many of your questions. READ IT FIRST!

All discussion relating to South Bend and similar lathes is welcome: lathes, tooling, methods of work, repair, restoration, projects, the saving of SBL by LeBlond, where you found your old SBL, when you first started working with one of these beasts, etc.

Picture attachments are fine but try to keep file sizes small. Be kind to our dial-up members. When posting materials from other sources, be aware of the Copyright restrictions. If you know the material is copyright free its permissible to post it. If you are unaware if its Copyright stats its best to offer to send individual copies.


Please remember to trim your posts. Quote only enough of the previous message to maintain the continuity of the thread.

Brief postings by members on items for sale/trade/need are fine. Please offer them here first then eBay.


This is not a commercial group, but members "in the business" are welcome to let the group know about on-topic services. Please note however, that SPAMMERS will be banned.

FOR SALE POLICY

Sale of personal items may be advertised to the list. However, it is asked that all transactions take place in private. This includes replying to sellers and pricing information. It is suggested that sellers include geographic information and shipping policy in their posting.

Commercial activity is expressly prohibited by Yahoo Groups Terms of Service. However, discussions by members "in the business" are welcome to let the group know about on-topic services.

Please note however, that SPAMMERS will be banned without recourse.

AUCTION POLICY

It is asked that before any list member places an item for sale on an online auction service such as Yahoo, Ebay, etc that they offer it to the group first as a courtesy to the membership. Publicizing of personal auctions not offered to the group first not only is in bad taste, but is highly discouraged. See section on For Sale Policy for further information.

From time to time, there are unscrupulous sellers encountered through online services. It is permissible for members report the actions of these sellers, however please refrain for making any disparaging remarks about these individuals. The proper place for leaving feedback is at those online services.

Re: South Bend 9" pulley systems

The spindle pulley or the counter shaft pulley?

The spindle pulley - probably not, just judging from the spindle thread and through-hole sizes.

You might have better luck with the counter shaft pulley.

A 4 groove pulley was not offered on the 10L . It was offered on the 9” and the 10K.

Sorry, but that is also misguided. It is horsepower that moves metal. At 0 rpm you can have all the torque you want, but no work is getting done.

While I do think that the clausing butcher on ebay should be shot, he is somewhat correct. Since horsepower is directly proportional with speed, at half speed you need a double HP motor to maintain the original metal removal rate that would be afforded by a 2:1 countershaft. So, if you want lots of HP down low, you need a big motor. Now, that does mean at higher speeds you are going to have enough grunt to break stuff. Belt slippage might help you some, but there is no reason to have 7.5 HP on a small lathe. A countershaft is much easier.

I am very strong technically but am poor on expressing myself without a technical edge so please excuse me if I come across too strong.


Torque is what produces work.  Work is what removes metal when we are turning it.  Power is a function of how much work you do in a given amount of time.  Torque is what we care about when we size motors – most of the time.


With that said, most applications state the required horsepower, but at a given rpm.  Nothing wrong with that as we know what a motor will put out in torque if we know hp and speed.  We just need to remember that up to base speed (rated motor rpm) the motor produces constant torque and produces constant horsepower above base speed.  We also need to know that hp = torque x speed / 5250.  This is the basis of all motor applications.


I work with motors almost on a daily basis.  Was working on a new 20,000 hp motor application this week.  I am the final technical sign-off (including sizing of the motors) on many projects including 3 multi-million dollar projects we are working on right now.  I know my motors and motor applications.

Thanks for sharing but that is so misguided it's not even funny.  Its crazy funny.


Motor VFD basics:


Below base speed (rpm the motor is rated at) a motor runs in constant torque mode.  Torque is what you really care about because it develops the force necessary to do work.  


Let's use a 1 hp 1750 rpm 60 hertz rated motor for example.  This motor is rated for around 3 lb-ft of torque.  That means at 0 hertz (not turning) it is rated for 3 lb-ft, at 30 hz 3 lb-ft and at 60 hz (rated speed) 

3 lb-ft.  It will develop a lot more than 3 lb-ft of torque but is rated for 3 lb-ft.
Power (hp) = torque x speed / 5250.  At zero speed you have 0 hp, at 30 hz 0.5 hp and at 60 hz 1 hp.  Above 60 hz you have constant hp (1 hp) and the torque diminishes proportionally.
A drive that is run in scalar mode (volts/hz) will lose low end torque.  This was a problem with early drives and current very cheap drives.  Modern drives that have sensorless vector control do not lose any torque at low speed.
His lathe originally came with a 1 hp motor.  All he needed was a 1 hp sensorless vector drive and he would have had the same performance as originally with all the benefits of a VFD.

Jim,

First I tried to put the pics in as attachments.  It took the attachments but they don't seem to show up as pictures (or at least I could not find them).

I used the help feature on the forum and found how to add pictures to an album but not to a thread.  All the other forums I participate in make it pretty easy to add a picture by just hitting an add image icon.  All  my images are on my computer - I don't have any on the web.

I then googled it for help with no success.

How does one add the pics to a thread?

A 33HP motor ? Why ? a 5HP VFD will not work. You need a 1/2HP motor maybe a 3/4HP not more

I wouldn't use wood.  Hopefully I load the pics right but this is what I will be installing for my 16 inch.  The selector switch and red light is power on.  The pushbuttons (might be original to the lathe - not sure) are forward, reverse and stop.  I made the box with the pot and power switch.

Radio Shack or Ebay or Amazon or Waytek should be viable sources for a pot.  Remember you also need a knob and label.  Probably a 5k ohm pot but you need to read your manual to be sure/
