First Drive With the Singer

Last Updated on Tuesday, 20 November 2012 13:53 Written by Administrator Monday, 19 November 2012 23:22

The Singer has basically been in running condition for quite a while but I just have not even tried to drive it. The main reason perhaps being the fact that getting it out of the garage required a little bit of manoeuvering and I have also have had something else to do, like repairing the SAAB engine. Yesterday I finally took the Singer out from the garage and tried to drive it the first time. The engine had been running already earlied and so it fired easily on the first try and I let it warm a little for a while.

Then I realized that there was something wrong with the clutch because it did not release properly. It took a while to find out that it did in fact release but the adjustment has something wrong since the clutch is properly engaged when the pedal is up, released when the pedal is about half way down and again engaged when the pedal is fully pressed. I need to check the adjustment, hopefully the problem is there and I do not need to open the clutch. However after this finding I was able to give the car a little spin on the yard by just pressing the clutch half way down while shifting gears.

The good thing is that beside the clutch everything seems to work as supposed. Of course there is still some adjustments to be done, for instance I suspect the carburettor fuel level may be a bit high because of the black smoke puffs also whet the choke is not on. While doing the checks before the drive I also noticed that the right front brake hose was little wet and I tightened it's connections. I need to keep an eye on that to see if it is the hose itself that has a leak.

 

Chassis Plate Fabrication

The chassis plate of my car had been lost at some point during the life of the car. I have found out that some Singer clubs have manufactured reproductions at some point but now they are not available anymore. Therefore I decided to try fabricating the plate myself. The plate is brass and it has the texts etched to the surface. First I needed a good protograph from an original chassis plate to create the graphics. When I collected ptotographs from the plates from different sources I noticed that there a different versions of the plate.This is described more in another article here.

After selecting the photograph I would use, I corrected its perspective and scaled the photo to correct chassis plate size. Then I created the chassis plate geometry with a vector graphics program by using the scaled picture in the background as a reference. This way I could get the geometry very close to the original. Then I printed the graphics onto transparent slide as a mirror image to be used as a exposure screen. This is because when you use the screen upside down, the ink side is against the exposed surface and creates more accurate edges.

I cut brass plates that are slightly larger than the final plate dimensions to allow some toerance on the exposure screen placement. Then I protected the backside with wide plastic tape so that it will not be etched later. The front side of the brass plate is then painted with photo sensitive paint (I used Positiv 20 that is widely used in printed circuit board fabrication and is available from electronics stores)

When the photo sensitive paint is fully dried the screen transparency is placed on the surface and suporrted with a glass plate. This combination is then exposed to ultraviolet light (The exposure time depends on the light used, I used an old alpine sun lamp and a two and a half minute exposure). The exposed plate is then developed by placing it into a solution of mild lye (NaOH) where the exposed paint dissolves and the unexposed is hardened so that it will protect the surface from etching.

The developed sheet is then placed into etching solution (I used ferrichloride FeCl3 which is also available from electronics hobby stores). The etching time depends on the solution strength and temperature. When the etching is deep enough the plate is taken out of the solution, washed and the remaining protective paint is removed with acetone. Below is a plate in developing solution and a developed plate showing the geometry on protective paint. On the right are two developed plates on the left and two etched plates on the right.

The etched plate is then painted black and let to dry. The high portions are then sanded to bare brass while the etched recesses retain the black paint. I still do not master the process throughly but the result seems somewhat decent already, as seen below right.

Side Screen Restoration

The side screens in my car were in original but very deteriorated condition as shown in the pictures below

The side screen frames made from D-section tube were in quite decent condition and shape.I sandblaster the frames and painted them black. The sceet metal paltes inside the screens were obviously originaly non-painted and they were so rusted that I needed to fabricate new plates.

The side screens are attached to the fixtures on the top edge of the door with conical peg on the bottom edge of the screen. The fixture parts were in good condition because they are chromed brass parts. However the chromed steel pegs were badly rusted so I fabricated new pegs from stainless steel.

Because of the bad condition of the side screens it was in many places difficult to figure out how the fabric has been sewn on top of the sheet metal plates inside the side screens. I made some paper templates to find correct shape for the different flaps on the screens.

Sewing of the double duck fabric was quite an effort because the material is so thick. It was also challenging to sew just outside the sheet metal plate insede the fabric, as required in multiple places on the screens.

The original toughened windows were in good condition, thy just needed proper cleaning. However the chromed brass window channels were corroded. I fabricated new channels fron stainless steel. Getting the channel lengths and corner miters correct was bit challenging but after several trial fittings I got then adjusted correct. I alse made new pull tabs for the screens.

Restored side screens. Looks pretty decent.

Instrument Panel Finished

I have now installed the self fabricated start and choke cables. They do look like the originals and were the last components to be attached on the instrument panel.

Start And Choke Cables

Last Updated on Thursday, 08 March 2012 21:37 Written by Administrator Saturday, 25 February 2012 00:00

The original Singer start and choke cables have a 1/2 inch installation hole on the instrument panel. I could not find any generic cables that would have this installation hole size, they all seem to be for a smaller hole and also for a thinner panel. Therefore I decided to fabricate new bezels to the cables to make the cable suitable for 1/2 inch holes and have a long enough thread to go through the instrument panel. It also made possible to reproduce the original bezel size and shape to make the cables look like the originals.

I turned the new bezels from solid stainless steel, polished the bezel and then attached modified generic cables into them. I removed the ´╗┐plastic knob from the generic cable and threaded the cable end to accept the new fabricated knobs. Below are the new bezels in variour stages, the bezel attached to the cable and fabricated cables with an original cable.

Doors installed

After finishing the door upholstery I installed the doors in place already a couple weeks ago. Today I adjusted them properly by adding some shims under a two of the hinges. I also installed the outer door handles. The doors function now very nicely and also close with a nice sound even thoug they are very light because there are no windows on them.
