Gallery-03 - P3 Alfa Romeo

The Main body patterns - four in number - were carved in pear

wood and pinned together then made to fit the chassis frame. 

The hood and cowl were formed over these in brass sheet.  The

body/cockpit formed in copper sheet to accomodate the shape,

while the rear section/ fuel tank was formed in aluminium sheet. 

Two further patterns were then made, one for the rear under-tray,

and the last for the front apron.

The pattern for the rear under-tray was carved in pear wood, then

covered with a .010” thick layer of sheet wax - as  used in official

pattern making - This was then put into a box and a resin form

made of the working surface, to make  two matched dies.  Between

these was then formed in sheet copper, the under-tray for the miniature.

The pattern for the front apron was carved in iron, and a resin form made

of the top surface.  I used iron as the sheet metal to be formed into it, needed to be  formed in the final stage with hammer and punches of various shapes, as the final shape had to be crisp and sharp.  The brass sheet was first marked out for the two sets of louvres.  After these were formed in the louvre press, it was put between the iron and resign dies to form the shape, after which the final shaping was undertaken with the hammer and shaped punches.

The fuel tank pattern was made in two halves, these were mounted end to end with a spacer between and a resin form made as above described for use as matched dies. .015” aluminium sheet was then annealed and formed between these to provide the two halves of the fuel tank.  The two halves were then - with great difficulty - soldered together.  It is possible to solder aluminium, but it is not an art that I have mastered, after this attempt, I stayed with brass and copper, except where an aluminium finish was called for. Also the aluminium solder is not the bright silver of aluminium so it cannot be used and polished with out showing a dull grey line  for the soldered joint.


For those looking for more information on the construction of the Falls of Clyde, I am running a ‘Log’ on the building of it on the ‘Model Ship World’ web site.

Check out < > and search for ‘Falls of Clyde’

Most of the photos will  be the same as here, but there will I hope be more insight into the actual working of the materials and building of the model.

Four photos are added at the start of each month and relevant text on the building.  It should be running for a considerable time to come, and hopefully will not repeat what I have here too much.
