[Sarah Carlson]

Thank you for sharing! That's a great post and great example of how to 
respond to well earned wear and tear. I still fret a little bit over marks 
but maybe I'll learn to relax about it.

[RBW] Re: Help me repair Pam's Silver shifters

[Eric Marth]

I don't think the pawls wore out, necessarily, it's that they're missing 
from the shifters I received. 

What's more likely is the spring wore out. I found springs, haven't found 
pawls. 

Christian, I thought of Send Cut Send, as well, I've used them in the past. 
Hand cutting pawls is off the table, too involved!

I too am impressed that the pawls have worn out. I havent seen it mentioned 
yet, what is the original material of the pawl?

For 3d printing, Shapeways.com can print in a variety of materials with 
good resolution and decent timeline. 

For lasercutting, Sendcutsend.com is a good economical option if they have 
a stock that matches the thickenss of the pawl. Resolution with laser 
cutters is pretty good but oversizing the mating surface and filing to fit 
would probably give the best result with the least amount of fiddling. 
Might have to work around a minimum size requirement but you could gang a

A jewelers saw, flat stock, and some paitence would do the same but theres 
a little more skill involved. 

If you need any help drawing it up for cutting shoot me a PM. Happy to help

Wes, Pam’s bike is a model of beausage. There is no Betty Foy used 
harder…maybe Caroline Gollum can give Pam a run for her money, but that’s 
about it. (Caroline wrote in a recent thread that her well-loved Betty had 
a stem seized and then later they discovered the skewer to the wheel was 
seized, too.) Pam just crossed over 74,000 miles on her Betty. Not bad for 
a bike purchased in 2011!

Here is the 10 year anniversary post Pam did about her Betty. I’m sure that 
little bike is far more marked up now than it was in those photos.

[RBW] Re: Help me repair Pam's Silver shifters

[Garth]

A couple things with the ST Sprint shifters Pam. Firstly I don't know for 
sure, but I'd venture to guess the compression washer Riv and others sell 
for the Dia Compe/Riv versions will likely work as I thought these were 
based on the Sprint tooling. Secondly, I read this about Campagnolo DT 
shifters that slip, that is to apply some rosin powder to the inside of the 
washer. Rosin is a tacky powder typically used by baseball pitchers for 
better grip. This gives the shifter washer some added friction. Any 
sporting goods store that sells baseball stuff with have either a rosin bag 
or a bottle of powder. More friction inside the shifter means it doesn't 
need to be tightened as much, hence last longer !

[RBW] Re: Help me repair Pam's Silver shifters

[Pam Bikes]

I ordered a new shifter but - duh - ordered the wrong one.  So I ordered 
the correct one.  It's on it's way.  

I promise I'm not lax about my bike.  But I'm not overly careful.  Parts 
wear out and break.  I like a tall kickstand and I strap my purse on the 
handlebars and sometimes it falls or the wind blows it down.  I have been 
better.  And sometimes I get it off Amtrak and it has fallen apparently.  
So now I have some foam and a cardboard tube I put on the L so if it falls 
it won't break hopefully.  But I know I'll need another shifter at some 
point in the future.  

I like to keep spare parts in the closet.  I use my bike everyday. 

BTW I did try to put an old pair of SunTour shifters on and for some 
reason, They wouldn't get tight enough to have enough friction to hold.  A 
friend had a pair I would have used.

Thank you to everyone who is helping us out.  Among us all we have all the 
parts.

[RBW] Re: Help me repair Pam's Silver shifters

[Wesley]

I am frankly amazed at the workout Pam is giving her bike, to wear out 
multiple shifter pawls! I can imagine a few ways to do a repair, none of 
which are "worth it", in terms of resource and money cost (3D printing, 
filing down a bit of aluminum bar, CNC milling). The most expedient fix, 
IMO, would be to epoxy the ratchet gear to the shifter body so that the 
both directions work in friction mode.

[Garth]

I suspect the bar end shifter is more like the thumbshifter design in that 
the ratchet and all related parts are notable larger than on the Sprint DT 
version. I like the idea of 3d imaging and machining of parts, if/when 
possible !

[RBW] Re: Help me repair Pam's Silver shifters

[Eric Marth]

Thanks, Michael. IIRC the Silver 1s are copied from the Suntour Sprint 
downtube levers. From this diagram it looks like the design of the Silver 
levers is very similar. But the depiction of the pawl (No. 3, "Ratchet 
spring A) looks considerably different than the Silver pawl. It could be 
that other ratcheting Suntour levers contain the parts I require. 

The real bear of the Bar Cons is item No. 15, the hexagonal axle nut! 
There's someone on iBOB who 3D printed some.

[RBW] Re: Help me repair Pam's Silver shifters

[Michael Hammer]

The mechanism looks almost identical to the Suntour Barcon (of course) so 
broken Barcons might be a source of parts.  In addition the stem or 
downtube mounted Suntour power ratchet shifters might also have the 
spring.  See velobase 
here: 
https://velobase.com/ViewComponent.aspx?ID=39b0c9b8-10d7-4324-8bf4-f65eca2d209a=104
  
The power ratchets might be found at a bike recycling place.  Here's a

Great idea about 3D printing, Peter! I'll reach out to Riv on the off 
chance they can get me the file I need. 

Our local library has a maker space with a 3D scanner and 3D printers, so I 
can go get certified and see if I can make some stuff! It's about a 5 
minute walk for me.
