Re: Switch Smoke

Years ago I sold my South Bend 9A. When the prospective customer turned it on, the switch arced and smoked a bit, and blew the breaker.

Not good timing. :-)


Switch Smoke

G K
 

Working on the SB9 tonight, and smelled a little burn.  Flipped the switch off. looked around and saw no issues.  Flipped it back on and pop goes the breaker, and smoke from the switch.  I believe the switch is the original (1942) drum switch.  Unplugged it, and took the cover off the switch, and the jumper was fried.  No idea why.  I'm not an electrician, but can use a voltmeter.  Suggested troubleshoot? 

120 volt circuit. Furmas R44, 6-terminal switch, Dayton 3/4 hp motor.

I'm planning on pulling it apart tomorrow and look for any additional burned wires, but I do not believe I will find any from a cursory look.  Then I'll wire a receptacle directly onto the motor to see if there are any issues there.  If were good there, I will re-wire the switch and see what happens.  Maybe some chips got inside and caused a short.  Not sure.  Any chance capacitor went back and caused the short?  The only burn smell is in the proximity of the switch, but that could be where the smallest gauge wire (jumper) is located.

Thanks,

Greg

47/37 Metric Transposing Gear

I am not sure if this is your problem.
On the lead screw is a spacer. It allows the gear position to be moved to engage either the inner or outside gear on the compound.
Here is a 127/100 setup on my 9” change gear workshop.

Is this your issue.

Thanks Dave, I wanted to see you solutions. 
I have a slotted plate that I have been thinking of using in a similar way.

Hi Jim, Basically I decided to make three tapered spigots to fit onto my T slotted milling plate, a vertical slide, and a rotary plate ( with a' dividing head' feature) to then fit them onto the existing cross slide with the compound slide removed.

I think I shall shelve the idea of a T slotted cross slide for the moment. The Myford is an option but the V channel is about 9mm wider which would mean quite chunky gib strips plus the additional machining required to adapt it. I tend to try and make most  attachments for my SB. To date that includes two and three point steady - from a pulley wheel!, taper turning attachment, thread dial to name a few. Not the real thing but they seem to work!

Thanks for the offer Frank, but living in the UK the transit costs make it hardly worth it. I'm sure someone more local could use it. Since posting the query I've received some useful info. and using that I've adapted what I've got to give me a few milling options using the existing crosslide. Dave

I’m a proponent of the uncut serpentine belt.  I have had one on my SB9a for about 7 years now, I think it will last a lifetime. When you disassemble the spindle, take the opportunity to change the felt plungers and replace the fiber end washer with a needle bearing conversion.

If you really don’t want to disassemble the spindle, I have the below belt on my SB13. They are available on eBay for about $25.

The fellow who briefly owned my 9C before me had cut a serpentine belt and crudely laced it together. I improved on that, following the lacing instruction in the SB manual and using 50 lb test Spider Wire. That worked well and the lacing lasted about a year.

Then I decided to "bite the bullet." I bought a new serpentine belt and removed the spindle to put it on uncut. Similar disassembly of the drive pulley assembly. That has worked like a charm for several years now, with no end in site.

Ebay has several sellers offering custom belts for SB and other lathes. Leather and synthetic, cut to length and with the skived joint or the alligator-style joints. Looks like $30 and up with shipping. https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=south+bend+lathe+belts&_sacat=0

May also be folks local to you. I'm in OKC, and my former employer had a couple places the could get belts made for their old equipment. Check your Yellow Pages if you don't see something you like on Ebay.

HTH!
