I just tried the bell crank lever from my 29K71 in the 29K1 and it DOES NOT work - yet!

The BCL fits technically but it has to be modified otherwise it is rubbing on the revolving handle and does not feed properly.

So I will try to install more 29K71 parts and see what exactly is going on...

To be continued.....

okay....

I now have installed the revolving handle, the motion ring and the bell crank lever of my 29K71 in the 29K1. All 3 parts fit w/o problem - at least in my case - not sure if this will work on all 29K short arm machines.

I now get 6SPI max. out of it WHEN I have almost zero tension on the blade spring but that means that I have not much foot lift and I can sew maybe 3-4mm thick. When I put more tension on the blade spring I have a higher foot lift but the stitches are shorter.

So it could be that just a new + modified bell crank lever can do the job.

I will order one and will modify it. So in case it works - fine - if not then this project is dead, I don´t want to invest too much money in it.

some pictures of the bottom housing.

When I polished the name plate I found a different nomenclature on the backside of the tag - pretty interesting (but not overwhelming).

I just have ordered the bell crank lever for the 29K71 and will see what I can do with it...

I use electrolysis all of the time as it is the cheapest and least labor intensive method to clean parts and even loosen rusted in screws.

wish I had seen this thread earlier- I am a passionate restorer of vintage home sewing machines, and have ~50. Plus my two consews. If you need parts and have trouble finding them, or if you are looking for specialist repair information, then a great resource is the Vintage Sewing Machine forum on QuiltingBoard.

http://www.quiltingboard.com/vintage-antique-machine-enthusiasts-f22/%C2'> ......some of the threads have thousands of posts.

these sorts of machines are straightforward, and addictive to repair. I love the close tolerances, and making a quilt on a treadle that is 100+ years old. I am sure that sooner or later I will run across a vintage industrial machine besides my Willcox and Gibbs(1890 chain stitch sewer) and drag it home.

when you get this running, I want to see a video!

I´m almost done with I´m just waiting for bell crank lever and some screws. New paint is silver + black. It will no longer use the treadle base, I have motorized it ;)

GOOD NEWS!

Today my last order from College Sewing has arrived and I was able to install the BCL.

I had to grind down maybe 1/2mm - 1mm on one side of the ring with my Dremel and voila - it fits and works absolutely perfect. But that was a bit of trial and error. Sorry I took no pictures but it really was a comparatively easy repair. Maybe I´ll take some pics in the days to come but for today I don´t want to rip the head apart again (I think I did it 5 or 6 times today).

Seems I now get 5.5 SPI out of it (w/o thread and on plain paper) but I will measure it again when I´m done with the entire setup. I think when I replace the feed motion ring as well I probably would get an even better score. But comparing with the 7 - 6.5 SPI I got out of it when I first cranked the machine it is a pretty good result!

So when you have issues with too short stitches I really would recommend replacing the Bell Crank Lever and (maybe) the Feed Motion Ring.

But be aware that you have to modify the parts and I only can speak for the 29K1 as I have not worked on any other "old type" 29K machine. But I think this repair will work on most other 29K too.

Conclusion until now: I think it it worth the money and the work!

To be continued... ;)

Or the quick easy solution as I have done. 5 minutes to put a spot of brass on the one part and a few minutes with a file to make it fit the groove on the other one and you save $$$$ and don't through away good easily fixable parts.

For sure a good idea but not everybody has hard soldering or welding equipment (like me) ;)

I´ll keep my BCL - maybe one day I can reuse it like you suggested but until then I have replace the parts when I´m restoring a machine.
