Powermatic 45 restoration

I did get some time to put paint on the bed.  The inside looks almost as good as the outside will.

I did turn the head stock over and get the underside of the housing finished so its done.
ning-bedandpartspainted-42365-94.jpg?wid

And lastly I got the underside of the banjo painted so that's a good sign.

Even though I had weather issues, I did move forward and that's always good.  Ja'nette wants to look at the
variable speed lower shaft to see if she can recreate it.  The damage on mine is almost too severe to put it back in.
I don't want this to die the first time I use it.

I ran into some issues with the reconstruction of my lathe.  Seems that the lower shaft variable speed (I don't make up these names I get them out of the manual) has too much play on the second bearing.  Its so bad that you can wiggle the shaft and hear the shaft hitting the bearing. 


 


ning-lowershaftvariablespeed2-42364-11.jning-lowershaftvariablespeed-42364-70.jpI took time to draw up the shaft to show it to a machinist.  I hope there is something that can be done.  I just received an email from a powermatic parts person who wants $50 plus shipping.  If all else fails that will be the way to go.

50$ doesn't sound bad for OEM part. You are still amazing with your restoration. Thanks again. bob

Thank you Bob.  I am really trying my best.  This is the first restoration I have ever tried.  I had asked my father-in-law to teach me about metal work (I am good at mechanics but never spent time with metal just wood).  Unfortunately we never hooked up before this project, so I have been learning on my own.  Besides he has been busy with a 1936 Ford V8 3 Window coupe.  He just got it back from the paint shop and now hes putting the interior in.  Little joke here though he has had that car since before my wife was born and shes in her mid 40's.


Yes $50 is cheap when you look at it (its an assembly and will be good to have additional spare parts if needed).

I agree, 50 bucks for the lower shaft is not bad at all. It would be fairly simple to make but I doubt ya could get it done for less.


 


That is going to be a sweet machine when you are done with it Doug .... Keep up the good work!

Thanks Shane.  I really am getting excited about this project.  I can see a light at the end of the tunnel (as long as its not another train headed at me LOL)

I went out this morning to check on the bed and head stock.  I had put some paint on the remaining areas before calling it quits last night.  I was pleased to see the paint was dry to the touch so I took off the tape. 


ning-bedfinalpaint1-42359-33.jpg?width=7Now if that picture doesn't say 10,000 words I don't know what would.  So much work has gone into such a small project.

Looking good. Keep it up.

Guys,


Won't be any updates for a couple of days.  I got sent out to Springfield Mo to install a MRI.  Should be home by Sunday afternoon.  Gives the paint some time to harden I hope. 

Hummmm, wonder if there are any woodworking places in Springfield?????

Doug,


Man you are doing some fine restoration work even for a seasoned restorer let alone a beginner. Just don't loose patience with the "detail work" as anyone that does a lot of restoration work will tell you ........ the difference between a good job and an excellent job is the sum total of quality work on all aspects of the restoration and not just a good paint job and lousy detail to bare metal parts, poor threads, bearings, worn parts that need attention, and the list goes on and on and on. I am reading between the lines and don't know you, but you have an exceptional "eye" for just a beginner on restoration and you may just get hooked on restoring machinery like several of us have. 


 


Here is an idea..........I only live an hour from Springfield, MO and was wondering if you have any free time please feel free to come visit my sheds as I have dozens of restored machines that I have done and we can compare notes if you want.


 


You can tell your father-in-law that I have a 1937 Ford coupe that I bought in 1966 for $100.00 and drove it 70 miles back home back then. It is still as I bought it and I need to restore it, street rod it, or sell it.


 


If you want to come over to visit please drop me a personal email to oldtriumphs>at<hotmail>dot<com


 


I hope that you can come over and visit.


 


Thanks ~ Dan Wyatt

Well I am back home and checked on the paint for the bed.  It feels much harder that when I left it.  This means that maybe I can get some more work done on the stand (sanding the primer) and possibly getting it painted.  I have to go back to Springfield Mo for installation on the day after labor day.  The schedule is 3 weeks of installation.


 


Have you ever heard of a ground hog installation?


Its when do your installation, turn your back and hit the on button.  If you see your shadow you have 6 more weeks of installation.

I have begun to put some of the parts back together with the paint now drying and hardening.  The first is the variable speed mount.  It has 2 arms, one that rides on the cam and the other that rides against the bearing plate.  The cam is attached to the variable speed dial.  As it is turned, the bearing transmits force to the upper sheave drive through the two arms. 


ning-speedselectorcontrolarms-42351-47.j


The bearing needs to ride on the cam and must be in the correct position.  The lock washer must reside between the bearing and the arm as shown.


ning-cambearing-42351-32.jpg?width=721The parts have a much better paint job now than when I started and most likely when it was new.  The parts did not have coverage over the entire surface.

The other arm has a bolt that rides against a bearing plate that is attached to the sheave drive for speed selection.


ning-adjustorforvariablespeedselection2-


I think I have to take that bolt and nut off and clean them up.  They are just not up to the standards I started with.

I couldn't help but want to put more back together.  The tool rest came to mind and so I went at it.


ning-toolrestpainted-42349-16.jpg?width=


I wanted to show it from all angles.


ning-toolrestpainted3-42349-77.jpg?width


Including the under side with and without the clamp.

I am still working on the restoration of the lathe.  I went to a welder to see if he could make something of the mess with my motor mount.  He told me most likely that the cradle would buckle when welded and suggested that I go to Graingers to buy a new one.  So I went to them and they told me they no longer have cradles that large.  The longest was just over 6 inches.  I needed one that span over 9.  Another friend told me to come to their shop, that there might be one that I could have.  Long story short, I have a new cradle but here is the one that came with the lathe. Minor work had to be done to the new one but it will work just fine.

I have a update for you today.  I went over and picked up the new lower shaft for my lathe.  It looked fantastic.The old one had damage shown below.


ning-lowershaftb-42347-32.jpg?width=721


Here is the new one installed in the L122 bearing housing beside the old shaft.


ning-lowershaftnewandold-42347-57.jpg?wi


Then I assembled the shaft with the motor pulley and lower sheave.


ning-lowershaftassembly-42347-9.jpg?widtFrom there it goes into the lower speed assembly.


ning-lowerassembly-42347-27.jpg?width=72


This is just a dry fit and will be taken back apart to clean up the bolts, washers, and nuts.  Then final assembly will come later when the stand has had a chance to dry and harden.  I will be working on the motor cradle and preparing it for primer today.  Then Sunday I will be sanding and painting the stand.  What happened to Saturday?  My neighbor just invited me to the Ohio State Footbal game.  GO BUCKS!

Well before I get a thousand responses that the bearing housing is backwards (it is) I have identified where the problem came from.  Powermatic's drawing was wrong in 1964.  The drawing has the L122 bearing housing facing as I have it built. 


ning-lowerspeeddrawing-42346-40.jpg?widt


This is wrong.  It should be facing the other way as in this drawing.ning-newermanual-42346-79.png?width=721


But even this drawing has issues. 


ning-mistakeondrawing-42346-74.jpg?widthI'm not trying to be picky but errors like this can lead to other problems.  At least this was a dry fit and can easily be corrected.
