Gallery- 01

After many requests I am at long last devoting a Gallery to the louvre

Press, that is featured in a number of Build Galleries, and has been

used in the creating of almost all of the car miniatures.  If it has louvres

on the hood, then this machine has produced them.

The machine consists of a cam operated ram, to the bottom of which

are attached the required tools, to match those attached to the base. 

It is made from steel gauge plate and mounted on a cast iron base plate.

The principle set of tools are for cutting straight louvres - for this the

ram is fitted with a small cutter wheel in the form of a ‘D’, the straight

side providing the cutting edge, the rounded side forming the louvre. 

This engages with a grooved plate, on which the panel to take the

louvres is clamped.  The grooved plate is mounted on a table, that can

be indexed from left to right, with precision adjustment, while also

being able to be moved from front to back, to adjustable stops.  The adjustable stops locate on two replaceable bars, that can be notched and/or shaped to match what ever combination of louvres are required.

On the P3 Alfa Romeo, some 32 different lengths of louvre were required for the panels on the top and sides of the hood.  Those on the top being tapered from front to rear,  With a tapered stop bar on one side of the machine and a straight one on the other side, a tapered set of louvres was possible.  On one side of the hood of the 2.3 Alfa, a step was required in the length of louvres as they passed over the steering box cover - a stepped stop bar on one side of the machine took care if the possible problem.

Several of the Duesenberg models required curved louvres to the side of the hoods, the centre of which is the centre of the spare wheel, from where they then all radiate out from.  A plate was machine with the requisite number of grooves, and a pivot point to correspond with the required centre and mounted on the indexable table under the ‘D’ Cutter.  A guide plate was then machined to be mounted on top of the grooved plate, to act as a clamp for the brass plate being provided with louvres, but also act as the variable stop for each of the cut louvres, as it is traversed from left to right under the cutting wheel. So producing the distinctive curved Duesenberg hood side panels.

With the ‘D’ cutter wheel replaced with a rectangular cutting press tool (punch) , and the indexing table replaced with the bottom half of the press tool, provided with a slot and spring loaded stop, to take the sheet brass side panel and to exactly locate each opening. The tool was modified to produce the rectangular openings for the sides of the Bugatti Royale hood.  The small rectangles pressed out, were then reassembled on frames, to represent the opening hood side vents.

In use the hood top or side brass plates requiring the louvres, is clamped to the table above the grooved plate.  This is then indexed by a wheel on the left of the unit to exactly match the cutting edge of the ‘D’ cutter wheel, to one edge of the groove below,  The top handle is them brought over to plunge the cutter through the brass plate, the table is then moved back and forth, with a lever on the right of the table, to set stops to cut the louvre.  The table is them indexed to the next groove and the process repeated, until all of the louvres are cut and formed.


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.
