HRG Aero

Some will have seen this little gem on the Slotforum or Tom Wysoms wonderful blog, Slotty Salad. Tom really is the one responsible for starting this one off as it began life as a SMEC kit.
Carved from a solid block of wood, painted and detailed, Tom did rather a lovely job of it. I expressed an interest in the model and asked Tom what his intentions were. Being the lovely chap that he is, he sent me both the master and the mould with the strict instruction to do what I liked with it.

Well I have, but the research required to find out a little more about these cars took some doing. Total number built of the Aerodynamic Speeder, to give it it's proper title, varies between thirty five and forty one. I guess as with any other small scale hand builders, the true history will be almost impossble to find. The chassis was HRGs own and apparently flexed so much that the suspension wasn't really required. Power came from a 1500cc SOHC Singer engine giving 65 bhp which was just enough to get it moving. The sleek shape adding to it's top speed of just 100 mph.

Produced from 1945 apparently, although 1946 is more probable to around 1950, the shape is of particular note. Aerodynamics in those days were very much in their infancy as far as automotive design went, but the effort the HRG designers achieved is as good as it got. All hand panelled in aluminium the car is certainly distinctive for it's day.

The model itself as mentioned was originally built from the SMEC kit and plans and research revealed that the latter was a little off from scale. The body itself was too wide by 4mm and needed slimming down. The plans also showed that the body tapered from the front wings to the rear wings in straight lines. In actual fact the body sides were parallel from a point in front of the front wings to the leading edge of the doors where it did taper inwards to the rear wings. Some fairly major surgery was required to rectify this. Once the correct width had been obtained, the car started to take on the character of the fullsize. The photograph above shows how it looked before the slimming down took place. The photo's below, show it after.

There was some fairly fine detail in the body too, such as the beading running along the tops of the wings and also the louvres. Tom had managed to capture this quite well, but when I re-cast the first body, for some reason some of it got lost. So there was no real alternative than to start all over again. The beading has yet to be added, as I feel it will be easier to apply it to the next cast, plus the fact that the liquid poly cement might just attack the yellow primer/filler and spoil the finish. The louvres took some thinking out and as ever, a solution popped up just when I wasn't expecting it.

Whilst I was rummaging around in the shed looking for whatever it was I needed, I spotted a box of tile spacers. The type usually used for bathrooms/kitchens etc. Being made of plastic, I thought they would be ideal, particularly as the number of ribs matched exactly what I wanted. Bingo! Cut to shape with a scalpel, sanded down and trimmed to fit, I think they look very good. One or two may need replacing before the moulding takes place as a little bit of damage has occured during fitting up.

The hood was made completely from Chemical Metal with just two small pieces of obeche to act as supports for the filler. The outlines of the hood frame were achieved by varying grades of wet and dry and one finger used to obtain the shaping in between. All the panel lines were filled and re-cut with a razor saw and the various details, such as side lamps, number plate housing, boot lid handle were made up from scrap aluminium.

The quarter bumpers at the front were built up from litho plate and filler and eventually will be cast in metal and polished up. Finaly the grille, or I should say one of six as I have seen that many variations. In the kit i'm proposing to include three, giving the option of building either a road car or a race version. An interesting little car, that's probably unknown to a lot of people. I think it looks quite cute!

Peter Seager-Thomas's wheels.

Some of you will have seen Peters wheels as they've developed over the last few months, and I think you'll agree that they are probably the best of their type around. They have been developed mainly because Peter felt that there was a gap in the market for something a little better than was already on offer. I tend to agree as everything else out there either falls short or are too blingy. Peters main aim was to produce a limited number mainly for his own use, with any remander going on Ebay. The thought of these little jewels vanishing I felt would be a shame, so I offered to take over production as they were just too good to let go. They will be available in a day or two from the GP-Miniatures website along with suitable tyres and spinners, or as some call them, wheel nuts.
The photo below shows the wheels in kit form. Four wheel rims, which are two part items, eight photo-etched spokes, one inner and one outer per wheel, hubs, spinners and tyres. An instruction sheet for assembly is also included, although I have to say that the thought Peter has put into them, means that they really are very simple and quick to put together.

The wheels shown are fifteen inch diameter and will be joined very soon by a sixteen inch version. The finishing touch to any model and one that will guarantee to lift it to another level.

Taffys P3

Hi Taffy.

I assume the nickname is related to Mike Hawthorn name for Wolfgang Von Tripps?

The Alfa in the picture driven by Carraciola is an 8C Monza. Rudi did in fact race a P3 during his time with Scuderia Ferrari.


Incidentally, I note that the 1/32 Scratchbuilt Slotcar Forum on my web page at least comes with a translation option, so try it everyone!


I like the car and as ever will make a few comments.


Later P3 Alfas did in fact have hydraulic brakes. These were introduced in 1935 with the Dubonnet independant suspension.

I tried to get a Mac pinches body but he no longer does them. I am working on a P3 body now and then.

As with other efforts, I like the finish of the car. A friend tells me all my cars look far too clean!

Ah, Bugatti wheels?

My own Alfa wheels are almost ready with final work under way. I hope I will be putting some sets together over the Christmas period. This is the prototype wheel. Production examples will be almost identical.




Like other wheels to date, the diameter is correct at 19", the number of spokes is correct and the pattern of the spokes is also correct. I'll post more details when I have all the parts.

Alfa P3

Peter, you wanted to see more proper pre-war cars? Here we go: For inspiration I had a picture of Rudolf Carraciolas white painted Alfa P2.



And I had a MacPinches body plus PinkCar-axles and motor... That is the result.
I know, they didn´t have hydraulic brakes at that times, but I wanted to do anything to make the front axle to look a little bit more serious and not like a toy...





My first attempt in airbrushing...






Used the PinkCar-axles for a couple of other cars, so I have a nice quartet now. More pics soon.
I hope , you enjoy!
