Feed Lifting Rock Shaft (FLRS) Reassembly

Hello everyone.  I sincerely apologize for my overly extended absence.  I could go into the details as to why, but that would be boring.  Instead we’ll just jump right into the reassembly of Ms. Rusty!

We left off last time installing the Connecting Rods.  The next step I tackled was the Feed Lifting Rock Shaft, or FLRS as I affectionately call it.  The next two photos show all the pieces/parts needed to install the FLRS.

All the individual parts 

Parts laid out in approximately correct location when assembled. It took me a bit to figure this out as I’ve been away from Ms. Rusty for so long!

The first step is putting one half of the feed dog raising mechanism on the left end of the shaft as shown below – be sure to put it on facing the right way (screw toward the inside of the machine)

The mechanism at the right end of the FRLS (Feed Lifting Rock Shaft) is used to raise or lower the feed dogs.  The pictures below show the position of the second half (front/left half) )when the feed dogs are raised and lowered.  Honestly, I’m not sure which one is represents raised or lowered.  I could make an educated guess, but I’m sure I’ll figure it out after the feed dogs are installed.  The screws will also have to be adjusted a bit after the feed dogs are in to make sure they are at the correct height for sewing.

At this point the rod is ready to put into the base of the machine. Lay the machine on its side with the bottom facing you and the balance wheel end to the right.  The FLRS attaches to the top legs in the base. Put the two “pointy” screws partially into the legs on the machine base on both the right and left side.  The photo below shows a “pointy” screw in the right leg of the base.

Place the FLRS bar between the screws and tighten a bit.  You don’t want the bar too tight, just enough to hold it, as you need some room so you can attach it to the connecting rod. Attach the end of the feed connecting rod (installed here) to the FLRS via the taper hole.  The connecting rod should be towards the balance wheel and the nut towards the bobbin area (see photo below). 

Tighten or adjust the end nuts and taper nuts as needed so when the balance wheel is turned by hand the connecting rod doesn’t bind or drag, nor have too much play.  It isn’t too hard to do this.  It’s pretty obvious that you need to move/adjust the FLRS one way or the other if you can’t even get the connecting rod to butt up against the taper hole.  This is what happened to me on my first try.  Once I had things lined up right, everything just slid into place.  After that, only minor adjustments were needed to make it rotate smoothly.  It seemed to me that if it didn’t feel/look right, it probably wasn’t right. 

Here is a photo of the bottom side of Ms. Rusty with the FLRS fully installed.

Connecting Rods Assembly–Part 2

Welcome to Part 2 of the Connecting Rod Saga.  Fortunately, installation of the second connecting rod was much easier than the first one.  The photo below shows the connecting rod with the end cap connected and the screws attached. 

The end cap must be removed to put it onto the horizontal arm shaft.  At the top of the cap is an oil wick, which in Ms. Rusty’s case was all dried up and looked like a piece of lint stuck in the top hole.  I applied quite a bit of sewing machine oil to the wick to moisten it and “fluff” it up.  The photo below shows the cap as viewed from above so you can see the oil wick.

Connecting Rods Reassembly–Part 1

First of all, let me apologize for the long delay between posts.  Between work, making 3 baby quilts, and a much needed vacation, I haven’t had much time for blogging.  The next month should be a little better so I’m going to try to post at least once every week for the next 4 weeks.  Now, back to Ms. Rusty.

The Singer 201 has two connecting rods –  one with an end cap and one that is forked.  This post will cover the forked connecting rod and the next post will cover the other rod. 

Below is a photo of the parts used to reassemble the forked connecting rod.  The rod itself (top), the feed regulator (bottom), the slide block (small rectangle), the hinge screw and the hinge screw washer. 

Upright Arm Shaft Reassembly

Today’s adventure was pretty straight forward for a change.  I decided to install the upright arm shaft, which is the shaft with gears that connects the lower gear shaft with the upper gear shaft.  A picture is below and a link to the disassembly of this baby is here.

The upper gear is the smaller one, and that is the one that I took off to insert into the arm of the machine.  The photo below shows the “flat” of the shaft where one of the set screws of the gear should rest against when it is reassembled.

If I haven’t mentioned it before, I’m lightly oiling all the parts with regular sewing machine oil before assembly.  This helps the parts slide together easier and adds a little protection from rust.

Here are photos of the bottom of Ms. Rusty and they show the “before” and “after” shots.  It’s easier to show pictures than try to describe where to insert the shaft.

 

Now here is a photo of the top end of the shaft, as seen through the arm side cover opening.

 

What this photo is intended to show is that it is not possible to attach the top gear to the shaft without first moving the gear on the horizontal arm shaft out of the way.  That is why I didn’t worry too much about exact placement when this gear was initially installed.  After the horizontal gear is pushed back a bit, then the upright gear can be put on.  This can be a bit awkward for one person to do since you have to push up on the shaft while aligning the gear over the hole, and then tightening the screw.  To solve this problem, I propped up the shaft at the bottom with a small box of toothpicks and then it went pretty smoothly.  An alternative would be to have a helper or a third hand, but I had neither at the time You can tell the gear is in proper position on the shaft when, using the words of the Singer Adjuster Manual, the end of the the shaft is approximately flush with the face of the gear.

The next step is to bring the gear of the horizontal arm shaft and put it in mesh with the gear of the upper arm shaft.  It helps to have a pair of bent nose pliers for this step to pull and hold the horizontal gear into place to tighten the set screws.  The photo below shows the completed assembly.

Then I rotated the shafts at the balance wheel hub to make sure everything was turning smoothly and nothing was binding.  The adjusters manual warns that the gears should not be pressed too tightly against the bushings as this could “retard the free rotation of the upright arm shaft”.

When I was sure everything was working the way it should be (at least as far as I could tell), I applied grease to the gears and did a few more rotations to work the grease into the gears.  I want to make sure those babies are ready for the big show when the time comes!

Next time I’ll tackle the connecting rods.  Oooooo – what fun!

Reassembly of Thread Take-up Lever

Today’s post cover’s the reinstallation of the Thread Take-up Lever Assembly and the Needle Bar Link.  These parts attach to the end of the horizontal arm shaft that we installed in the previous post.  Fortunately, these are pretty easy to put back on.
The thread take up lever goes on first.  A key land mark on this piece is the flat edge on the post for the set screw.
