Logan 6560LH Restoration

John, the first step after buying a Logan lathe is to go to logan actuators website and order a manual from Scott Logan for about $25. He can tell you when it was first sold and where it shipped to.
Scott also runs a Yahoo group named "lathe" dedicated to Logan lathes. Lots of good info there too.
 
Hi John,

I straightened up your first posts a little if you don't mind. Looks like you are getting some good starting advice. I have a 6561H and will use you project as a reference once I get started in tearing mine down. Keep the info and questions coming.
 
John, If I'm reading this correctly I think your talking about the worm gear that the lead/feed screw turns. The screw has a keyway running almost the entire length which the key in the worm gear runs in. That worm gear powers the longitudinal feeds as well as cross feeds. The cross feed doesn't actually have a worm gear to drive it, (unless it's different than the smaller logan models), it's driven by the big gear sticking out the top of your apron. I get the impression that the key in the worm gear is worn as well as the bushings it sits between. I don't think there are spacers between the gear and the bushings. You just have a lot of wear. I have made bronze spacers to tighten that up. You will probably have to make a special key to fit the worm gear. I would imagine those parts are very pricey if you have to replace them. I don't know where you would get that worm gear other than Logan. The bushings you could make. Good luck.

Hey;

There is always ebay for used parts, but I don't think they will be nearly as plentiful for this newer lathe as they are for the older ones. Yes, the prices from Logan seem pretty steep, but that is likely based solely on how much time they take to make. The fact that someone has gone to the trouble to make them available at all is pretty amazing, really. If you are just learning about lathes, there is a guy on You Tube called Tubalcain who was just recently making a new shoulder gear for his quick change gear box. He could not find on on ebay, and commented that a new one from Logan was "$200!" He found something to match the gear, and with a shoulder, but with different ID/OD. By the time he was done turning and making reducer bushings, he said the price from Logan looked about right, and he'd never make one again!

Try to explain your issues as clearly as possible, and take lot of pics. That will help those here with such knowledge to help you through!

Thank you already ordered manual should arrive tomorrow,unfortunately my lathe bed does not have serial no. Engraved on bed . Bed May been reground at some point. Do have casting date and no. Their appears to be some variation in apron disernable by serial no. I have measured all existing parts once manual arrives I'll contact logan to clarify .i have manual online some schematics do not match what is existing.some one has already done some replacement/repair,manual does give dimn. Specs for parts in question.

Thanks Randy there is a logan rebuild on this site I found when looking up logan ,it was logan 12"found it very informative ,unfortunately for me found after most of my disassembly was done,I guess I'm saying his was obviously easier and correct ,well that's part of learning curve or crash

thanks for input I will be posting more pictures soon,logan prices are worthy ,I'm just fiscally prudent you know cheap,I bought the lathe at good price , there always a trade off , will be contacting logan for clarification ,intend to do this as correct as possible , Thanks again for the responses, actually motivating to have others interested,never been on a forum before wasn't sure what to exspect. Thanks again
 
Good morning America
I am currently disassembling my new ally acquired logan 6560lh . Have back gear assembly,gear box, apron, removed, some things in apron don't look rite, worm gear severely worn and was difficult to remove.their was no key for shaft .shaft key aprox 3/16 but worm gear slot only 1/8".
not sure how clutch assembly functions, and how to identify how much wear is acceptable.
this is my first lathe rebuild . Any one out there familiar with this machine.

. Good morning America. Well I just got off the phone with Scott from logan,confirmed my suspicion wrong worm installed by previous owner, replacement parts for worm , worm gear,set of new bushing just shy of 1000.00 ,only paid 1025.00 for the lathe.
going down to local machine shop see what they will charge.luckily found source for back and revers gears,bushings that are a 1/3 of logan, some good news.and they are new old stock not used.
 
I guess the insurance company would tell you that your machine is totaled....but as long as you have patience you can make the lathe whole again. Is there any chance of making the worm gear you already have work? If it's just a matter of making some spacers to center it on the other gear (I'm having a problem picturing just how it sets in there...I'm thinking it engages the bottom of the other gear) that wouldn't be a big deal. It would be a lot more economical than having one cut at a machine shop. Keep us posted on your progress.

hey Chuck the sitttiaaaion is worm does not have key machined into it,it has a key way,the key way size doesn't even match key way size in power feed screw, and the treads beyond use.threads on worm gear are also to severely worn,I believe what occurred is they used a mismatched assembly that allowed key to wear and stress ,over load worm gear to worm to cause excessive wear,there was excessive metal frags in assembly, the positive is back gear,reverse gears,and gearbox gears are in good condition. It is what it is .going to exhaust couple other options, may just have to bite the bullet. Considered putting apron back on operate lathe utilizing 1/2 nut to machine parts needed, I just don't have the expertise to machine inside of the worm with the key.a simple inside diameter is one the but with a key incorporated into it is beyond my capability. All else fails bigger hammer
