My Logan 200 Lathe Rehab


First, I would like to thank those that have posted info on this sight regarding their Logan Lathes. I have accessed many of these threads and have learned a lot. Especially, I would like to thank those that have spent the time posting their progress on restoring Logan 200 Lathes specifically. Obviously, for me, these have been the most informative. It has been so helpful I thought I would post the work on my lathe hoping it will benefit someone else that heads down this path.


A little history

I purchased my Logan 200 Lathe on 12/10/2013 for XXXXXXXXX The serial number is 15012 so it appears it was manufactured in 1942 according to the info on the Logan Lathe Website. I had always wanted a small lathe in my home shop so when a friend mentioned his son-in-law might be interested in selling a small lathe I told him I may be interested. He must have told his son-in-law I was looking for a small lathe because the next day I had an email from his son-in-law with pictures of the lathe and his telephone number. I called him immediately and we spoke about what came with it and his honest assessment about its’ age, condition, and what would come with it. He told me it ran and everything works but he only used it to turn some plastic and wood. He was unsure about how it would be for turning steel and other metals. After finding out his price I went and picked it up immediately.


This is what it looked like at the location where I picked it up:

The lathe came with a full set of change gears (I think), six inch Cushman three jaw chuck, a steady rest, a lantern tool post, dead center, live center, some wood cutting chisels, and many misc. HSS cutting bits.


First, I should mention the last time I ran a metal lathe was in shop class in high school. I’m retired now so I won’t say how many years ago that was. Anyway, I had to refresh my memory in basic turning and facing operations along with learning the operation of this machine. Thanks to this website and YouTube, I was able to accomplish the basics.


I had planned on checking the machine over to assess what it needed and get started on refurbishing right away but other priorities took over. Recently, I returned to starting to work on this project. Getting reacquainted with basic lathe operations and working on several projects on the lathe helped me to determine the obvious needs of this machine. I’m sure there are many “less obvious” issues I’ll face once I start taking things apart. I was unsure if I wanted to spend time and money rehabbing this machine or just sell it and go buy a new 12 X 36 lathe. Cabin fever has set in and I needed a project so I guess I’ll get started on the rehab.


Getting Started

To date, I have purchased several items for this lathe as well as completed some minor repairs. I replaced the countershaft and bushings, installed a serpentine belt, installed a linked drive belt, installed a Phase II AXA size QCTP, and purchased a Shars 6 inch 3 jaw chuck and back plate. My spindle cone pulley gear had three teeth missing so I just purchased a used spindle cone pulley with gear from an eBay seller. It turns out this cone pulley with gear is in good shape but has been reworked with a brass sleeve and the ID of the pulley and gear measure 1.200 in. so as-is it is too small to fit my 1.250 in. spindle. I’m going to enlist the help of a small local machine shop to help me take care of that.


Yesterday, I started to take the lathe apart. I thought I would start with disassembling and removing the head stock.

Once I had the headstock off the lathe bed, I removed the back gears. Then, I was trying to figure out how to remove the name plate without destroying it when I noticed there were two tiny holes visible inside the headstock case. I used a small finishing nail that I ground flat on one end and cut the head off the other end and put it in a small chuck with MT2 mandrel. I was able to tap out the small drive screws and keep the name plate intact.

One of the surprises in disassembling the headstock was the keyed shifter gear LA-129 on the back gear eccentric shaft. The gear that came off of the eccentric shaft LA-125 has two keyways and looks like a 24 tooth change gear with an extra keyway to me. Unfortunately, I didn’t pay attention to which key slot was engaged with the key so it may be an adventure figuring out proper reassembly if there is such a thing. Has anyone else had a shifter gear like this?

I’m not sure exactly how well the back gears worked because the key was missing in the shifter rod so it was impossible to keep the rod in the right position. I was able to hold the rod out with the bull gear disengaged and the back gears worked as far as spinning the spindle. However, there was some noise that may be caused by the gears not meshing right because of the shifter rod key missing. I have a shifter rod key and spring on order from Logan.


Anyway, the pile of parts are on the bench and I’ll be focusing on the headstock assy. before moving on to the bed, apron, carriage, etc. It is apparent to me this machine has been apart before, maybe several times, for repairs.

That’s it for now.

CHARGE!

Not trying to hack your thread, but my back gear looked like the pic below.

Don't suppose it matters as long as it works. You do what you have to, eh? Also, I have a reference to that cone pulley gear on my thread. The originals on our old timers were not bushed. My replacement was the late bushed variety, and required use of that gear and the cone that fits it instead of my original. Again, no matter as long as it works and is not a cobb job!

Looking forward to paying you back!
 
Hey, Redlineman.

No worries of you hacking my thread. I'm happy to see your response here. Please feel free to post whatever you feel is relevant.

I see your shifter gear has one keyway in it which is what I suspected. I'm sure having two keyways will make getting it right twice as difficult. Although, I have not cleaned up my shifter gear yet with the hope I can figure out its' original position. When it was disassembled, I was not paying attention to how many keyways were in the gear expecting only one. Oh well.

If you look at the spindle cone pulley on the table with the rest of the parts, you will see there is a bushing in the end of the gear. The cone pulley that came on the lathe with the gear that is missing three teeth is in the plastic bag with all of the other spindle parts. Anyway, I used the Logan Spindle drawing that you posted on your thread to take the spindle and cone pulley to a local machine shop to machine the spindle to 1.225 in. where the cone pulley rides and bore the bushings in the cone pulley and pinion gear to 1.2275 in. That will remove the scoring from the spindle and give the proper clearance for lubrication between the spindle and cone pulley. Also, this will eliminate what I think was excessive play between the original cone pulley and spindle. You could grab the cone pulley and pull it up and down and feel it knocking. I think that contributed to the noise when running in back gears. Too bad I don't have another lathe lying around to do the machine work myself. Believe me, I thought about it. A new 12 X 36 would do. Anyway.............

Oh yea, I also took my back gear eccentric shaft in to the local machine shop with the other parts to have a screwdriver slot cut in the end to ease installing the shifter in the proper position. Thanks, again for that tip.

Today, I'm going to introduce some parts to the blast cabinet and then brush on some paint. I'll post more pics when I make more progress.

looking good already!
can't wait to see the thread progress...:)
 
I was able to remove the change gear threading plate off of the change gear cover the same way I removed the nameplate from the headstock.

Here’s the outside of the change gear cover.

I introduced the parts to the blast cabinet to clean them up and get them ready for paint. I’m just blasting off the old paint, washing the best I can to try and get the oil and grease out of the pores of the castings and brush on some paint.

Here’s a few of the parts after I brushed some paint on. By the way, I purchased a quart of Benjamin Moore Baby Seal Grey 2119-30 shortly after Redlineman’s post in 2013 about his research on the original color of the Logan 200 Lathe. Thanks, Redlineman.

I think I have some Glyptal left somewhere in my paint cabinet that I used to coat engine lifter valleys that I’ll use to coat the inside of my headstock to save some paint. As you can see, I blasted, washed, and painted the parts. I hope I don’t regret not using any primer.

I will continue the blast, wash, and paint the rest of the parts but I won’t bore you with posting pictures of them. I will post pictures of future assemblies, disassembly’s, and anything else that may be of interest.

That’s it for now.

Yur flyin, man!

At this rate you stand to beat both Tom and I! I sure wish you had done your resto before I started mine so I would have thought to knock the drive screws out from the back. DOH! I also wish that Matthew would make me a new badge. Mine is pretty hammered. As for the shifter gear, the tracks left on the back side should make it fairly easy to decipher. whichever slot they had used when you got it, you can bet it is a bodge to get around some mayhem done to the shifter mechanism itself. I think they regularly are exposed to mayhem. Mine didn't even HAVE a shifter!

I'll make sure I have my thirst primed for when you go to adjust the back gear lash. When you use that slot to adjust it, you'll quickly see that the beer will rightly be on you!! :D
 
Thanks Ulma Doctor.

Redlineman, the beer is already definitely on me!

Oh boo, great timing for me... I'm about to refurbish the same lathe... I appreciate your post, thank you.
 
Hey, lo7us.

The more the merrier!

There's a lot of very good information on this site for those rehabbing Logan Lathes. Certainly, I have benefitted greatly from others that have posted info on their restoration projects. I won't try to name them all. The main reason I am posting info on my project is with the hope someone can benefit from the info on my project.

Today consisted of more parts blasting and some painting. Also, I am supposed to pick up my spindle, Cone pulley, and eccentric shaft from the machine shop this afternoon so I have my fingers crossed all is done.

I removed the rest of the parts from the bed of the lathe. Since everything else was off the bed, I removed the tailstock, leadscrew, apron, saddle, and rack. I removed the leadscrew by removing the right bracket and spacing collar. Then, I removed the left bracket and pulled the leadscrew out of the saddle to the left. Next, I removed the saddle by removing the two allen head bolts that attach it to the carriage. Then, I removed the front gib and saddle gib and removed the carriage. I removed the rack by taking out the 7 machine screws.

At this point, the only thing left standing is the bed, bed supports, chip pan, and legs. I took the opportunity to clean up the ways with a lot of scraping and rubbing with some solvent and a scotchbrite pad.

The ways are in fair shape with lots of dings around the chuck area. It’s not as clean as some of the others I’ve seen on this site but I’m playing the hand I was dealt. Here’s a picture of the cleaned up ways and a close-up of the dinged area by the chuck.

IMG_0968_zpsesrt0ioy.jpg

I’ll be concentrating on cleaning and painting the bed, chip pan, risers, and legs. That will allow me to reassemble it as it is now and install the assemblies and parts as I complete them. Theoretically, anyway.

That’s it for now.
