Replacing the Chassis/Body Shell Bushings on an Olympia SM.

A few days ago I stumbled across a very nice Olympia SM-3 in grey crinkle finish.  I was thrilled to bring it home, but my excitement evaporated quickly as tried to type out my first line.  The carriage would advance to the 20th space on the platen, but no further without grinding.  My first thought was carriage issues or even worse, escapement. But the problem disappeared when I hit the shift lock.  So I checked the body alignment and sure enough the tab stops were hitting the top edge of the body shell. 

Time to replace the chassis to body bushings.  As common as this problem is, it should have been this first thing I checked on this machine. 

As you can see, the original bushings are slowly turning to goo and will need to be replaced.  These actually are not too badly degenerated.  At this point I can just remove the screws one at a time and pop out or scrape out the old bushings, slide new ones in  and replace the screws.  You may need to gently pry the body shell away from the chassis to break the old bushing away from the metal. 

This picture shows the proper size bushing you will need to provide proper spacing.  

This is a simple operation, but you will have to turn the machine upside down and place it one a well padded surface to keep from damaging it.  Try not to let any of the old rubber fall into the machine as it be like a bit of Oobleck in the machinery, only black instead of green an no apologies, sincere or otherwise, will dissolve it.  

If you've done it right, it will restore body shell alignment so your carriage and body shell are properly spaced like the machine to the right.  

 



Later we will look at what you have to do if your bushings look more like this.

On the Workbench

Nothing special on my workbench right now.  Just clearing up a few minor repairs before I start a couple of major projects.  Finished an Underwood Five desktop that was a complete wreck.  Missing a right hand platen knob, replaced several keys from a parts machine.  The previous owner somehow managed to get the platen installed backwards.  Should not have been possible but it was.  The front cover was gone and the side plates damaged.  Looked like they were forced into place with a ball peen hammer.  Wish I had pictures, but I somehow managed to delete them from my camera before I could load them.  It was only a dollar at the estate sale, but I would not have bought it even for that small a price had I not had an identical parts machine at home with a missing segment assembly.  It looks pretty good now.  It will be up on EBay next week if I can get moving.  

I currently have a grey Olympia SM-3 sitting on my bench with the usual rotted body to chassis bushings. Since this is a common repair I will post pictures of the process for any that are interested.  

My Argyle P201 is Here!!!

A few days ago I was trawling Ebay, looking for bargains when I came across a Nippo Argyle P-201 listed. I have wanted one ever since I read about them on Will Davis' Portable Typewriter Reference Site, but I never really expected to find one. It took Will a few years to find his. 

So when I found this one sitting with less than three hours left and no bids, I could not pass it up. It was only after I had put my bid on it, that I recognized the picture used as being the same on on Will's web page.

This is a mirror of Will's site.

I e-mailed the seller but he was not very helpful or willing to send me a picture of the actual item. I resigned myself to having thrown away my $35. But this afternoon the package arrived and I was astonished to find that I had received exactly what I had bid on. 

It needs some work. Two screws are missing in the carriage shift framework, so the carriage wobbles a bit when in use. I am hoping to get this fixed tomorrow if I can find screws the right size and then I can write a review of the machine. 

Update

I was finally able to get a pair of tiny bolts to fit this machine.  They are not perfect, but they allow the machine to function without the carriage rattling like a Ford Model T driving over a freshly plowed field.  

First some basics.  The Nippo Argyle is derived from the old Halberg design.  This machine was not a commercial success, but the basic design was reused by Nippo and Royal (with Royal having mush more success than Nippo.)  

This is a carriage shifted machine with 42 keys, and no tabulator.  Being a small flat portable it has the expected dowel plate design.  The body is metal and it comes in a zippered vinyl carry case.  This serial number of this machine is 2013988.

Not to upset any fans of this machine, but I would not want to write a 300 page novel on this machine.  Even with the repairs made it has a loose and imprecise feel to it.  Not as bad as an SCM Corsair or the like, but not as good as a Brother Webster.  To be fair I do not get the impression that this poor machine was valued as a prize possession.  Many of the typebars were slightly bent, the segment plate was badly gummed up and there is a dent in the ribbon cover.

It has parallel action on the carriage lift and shifts smoothly.  Most small flat portables with carriage shift simply tilt the carriage back, a much simpler and probably cheaper to produce design.  Due to a slightly imperfect fit of the bolts I put in, the carriage does not drop on its own and has to be pushed down.  I will be correcting this at the earliest opportunity.   The alignment does not seem consistent, some of the letters do not strike the same point twice in a row.  It is not obvious, but I tend to be a perfectionist.  I though that the problem might be the bolts I replaced, but the fit more snug that the originals so if anything it is more stable than it was straight from the factory.  

My verdict is, while this is a worthy addition to any collection it is best suited for casual correspondence or notes.  Not really suitable for serious writing.  

No, it is not for sale!
