The next stage of the Ponfa pram restoration job was perfectly timed for late summer when we had some dry days which were not too breezy.  The respraying of the pram had to take place out of doors.

I used silicone carbide paper to carefully sand down the body work and a metal file to remove a couple of paint bubbles from the wheels and spokes to prepare for painting.  I also applied Kurust to the spots on the body where the paint had been scratched away, I couldn't see any rust but just wanted to be sure.  The Kurust only turns black on contact with rust, otherwise it remains orange brown.  The chassis received the same treatment and proved to have very little rust.

The brown marks are where I painted Kurust on the spots on the pram body just in case there was any rust where the paint had scratched off

I bought Plastikote satin finish radiator paint in spray cans. I did not want the pram body to be shiny and was doing respraying of another doll related project at the same time so the paint (2 cans of it in the end) served both projects well.  I set up a large cardboard box on a table on the back patio in a sheltered corner and propped the pram parts in the box.  The rubber tyres on the wheels was carefully covered with strips of masking tape to prevent them getting painted.

I masked off the Ponfa pram label as I did not want it covered in paint.  The respraying of the pram body, chassis and wheel hubs was done in many short batches of spraying to provide an even coat with no bubbles or runs.  I also sanded down between some layers of paint with a piece of silicone carbide paper to smooth the surface.  The parts for repainting would be propped in different positions for each stage so that each surface received paint.  The paint was quick drying so I was usually able to add another layer every 15 minutes or so, with light sanding approximately every 4 layers.

I lost count of the number of spray layers which were needed to paint the pram body, chassis and wheels or the number of times I gently sanded the surface smooth, however eventually I was satisfied with the finish and was able to remove the masking tape.

The pram handle needed some attention before being put back on the resprayed body.  We discovered that the inside of the bolt holes had sharp edges which needed to be filed smooth and flat and also the handle needed very slight reshaping.

The pram handle showing that where the bolt holes are the handle splayed outwards, it also sprung tightly against the body of the pram and needed slight reshaping so it wouldn't scratch the paintwork when it was refitted.

My husband did the filing and reshaping and I bolted it back onto the pram.

Ponfa pram restoration - part 3

See Ponfa Pram restoration - Part 1 and Ponfa pram restoration - Part 2.

I took the Ponfa pram parts in a box to Dawn L's Midsummer Sasha celebration in June, Rosie S had brought her pram, which also needed some restoration, for us to compare.  Rosie's pram is a Doucet of the different body shape (there are Doucet and Red prams with the identical body shape and chassis to my Ponfa pram) and it was interesting to compare them.  Her pram hood was in much better condition than mine but the body was in need of restoration.  Theresa had also brought her restored Red pram (same body shape as my Ponfa) and of course we had Dawn's wonderful collection to admire (she has at least 15 miniature prams one of which she was in the middle of restoring).

After this for a while pram restoration had to stop as we had family events and the garden to concentrate on so it wasn't until later in August that I was able to devote any useful time to the pram again.

I took the plunge and removed the hood fabric from the frame.  I had noticed that the frame was a bit rusty and when I was still debating whether to replace the fabric or not, the rust at the joint made the choice easier - I did not want it to get worse and I knew how to treat it.  I am glad I made this decision as removing the fabric proved that it was beyond repair because of extensive rust staining on the inside of the fabric.  This would have been impossible to clean off satisfactorily.  I will keep the original hood fabric as it belongs to the pram.

I photographed the fabric removal in stages for reference during the remaking of the hood.  The lining, edging strip around the inside top of the hood and outer fabric were stitched onto the frame using a thread which went through all three layers, in other words all three pieces were stitched on at once.

Before reshaping the frame I sanded it down with the fine grade silicone carbide paper to remove any loose rust.  The surface was not heavily pitted so I could tell that the rust period was only from one short time in the history of this pram, which was a relief.  A heavily pitted surface would have resulted in the frame being much less robust and possibly unable to withstand reshaping.

To correct the frame distortion I made a cardboard template of the correct shape of the curve so that the two sides of the curved frame section would match. One side was more or less okay, so I traced this onto card and cut it out.  This gave my husband the curve to work to when reshaping the frame.

Once all the hood frame parts were reshaped (he used pliers, a bench vice and bare hands) I painted Kurust onto the main frame where the rust had been. This special rust treatment turns the old rust patches black and prevents any further rusting, as it provides a fine protective coat on the metal.  It had to dry then be rubbed over with paper towel to ensure there was no residue remaining which might have stained any future fabric.  I then painted the joint areas with silver paint where the two sections of the frame are joined together with nuts and bolts, as these would be the only areas of the frame which would show once the fabric was stitched in place.
