Has anyone added an X axis motor to a South Bend Heavy 10 c/w taper attachment?

If so any photos?

Thanks
John

Bull Gear plunger on Heavy 10

Hi again,
    Well, I had some time to mess around while waiting for an answer and discovered it on my own. I made up a plunger (on a Unimat 3 that I also have) and that sucker won't go past that spring in the bull gear without removing the retainer spring as far as I can tell! Maybe if you chamfer the front enough it may,  but then I don't know how effective it'll be in the pulley. Might have too little "bite" to be effective.
Thanks anyway, and at least I've now contributed something to the group however uninformed it may be.
Thanks again,
Art

Bull Gear plunger on Heavy 10

Art Port
 

Hi,
   This is part 2 of an introductory note with a question. I am rebuilding a heavy 10 and find that in a previous move the plunger fell out of the bull gear and took a walk for itself. The whole spindle is currently apart and I'd like to get it back together forthwith. Can I insert a plunger into the receiver after the lathe is reassembled (and I fabricate one) - will it just sneak in through the spring retainer and stay - or will I have to make one before I put the bull gear and pulley system back together on the spindle? That would NOT be fun, in my book.
   Thanks,
Art Port, who's been lurking here for over 20 yrs without a question to ask or advice to offer. Perhaps after this deep dive into my SB, I'll have the experience and hubris to jump in somewhere!

Bill,
The winding up and binding suggests to me that maybe one pair is dragging or jamming on the pair next to it or on its shaft. Can you reach in and wiggle each gear to make sure none are stuck on their shaft?

Thanks,

I would say NOOOO, do not pin the f to d.  I'm pretty sure that would lock the gear train up.  Any chance the left tumbler is bent or worn enough that the tumbler idler is dropping out of mesh when in the e or f range?  Did the gearbox work fine previously and this problem just appeared one day?

Re: Twin gear box

Check the lubrication between the cone pulley shaft and the spindle. 
In back gear these use the spindle as a bearing. There is not a lot of clearance here. 
If you are using the teflon grease, you should take the pulleys off and lubricate the Id manually and the OD of the spindle manually. Do not rely on sticking some grease into the grease/oil hole. 
With grease this should be done yearly. 
I prefer to use oil for this reason.

Regarding copyright of HTRAL: I am not a lawyer, but I will put in my two cents anyway. 

Reading a history of South Bend found at www.southbendlathe.com it says the the authors of HTRAL are John J. O’Brien and Miles W. O’Brien, two identical twin brothers. According to the history, Miles died in 1936. John died in 1946. 

Now, reading a Wikipedia article entitled “Copyright law of the United States”, the article reads “Copyright protection generally lasts for 70 years after the death of the author”. 

1946 + 70 = 2016, so presumably HTRAL would now be in the ‘public domain’ and no longer under copyright protection.

I have numerous hard copies of HTRAL, so I don’t need any electronic pdf files of same.
