Hi all,
some of you may know that I recently had a heart attack and so am having to find things to do that come with no pressure, while I "recover". (I don't actually feel any different from before "the big pain"). But we must do what the doc. says.
So, I have a couple of projects on the bench which I could have a go at, slotcar-wise. One of which is a model I started on years ago, then got busy making F1 masters for you lucky people.
I have always been a huge fan of specialbuilding. From classic hot rods to English Specials. I guess chief amongst these latter must be Bloody Mary, built from a wooden chassised GN by the Bolster brothers and finished up by John with first 4, then the classic 2 J.A.P. V-twins. I love its hand bashed ally body, its bare minimum work and the fact that it is so Imperially English.
I will get some photos of the starting bits and bobs. I've already made the main chassis members in brass and am working on the bracketry that holds the GN straight tube front axle. The bodywork will be done in aluminium, like the real one, too. I like to make models in the form of putting the motor where the engine would be and driving in a similar way to the real car, so this will have two tiny Mashima motors using belt drive (because you can't get scale chain).
I'm hoping to use a set of RS Slot Racing's new 19" scale wheels with A7 spoking and skinny tyres. We are in posession of the CNC turned ally wheels, but are awaiting the p/e artwork for the spokes currently. I can't do CAD and the etchers no longer accept hand drawn a/w.
Cheers, Martin

Hi Martin
I wasn't aware you had had a heart attack. I do hope you are well and that you continue to recover back to full fitness.
Cheers Andi

Just laid it all out again, because I couldn't find the bits I'd made and I didn't taper the chassis frame anyway! The overall size of this, in 1/32nd scale will be 3 1/2"x 1 5/8"x 1"! Rather tiny for a twin motored model, so it should be rather fast.
Has anyone else thought of making hill-specific models? There so many fabulous cars, such as the FryKaiserwagen, Basil Davenport's Spider, the Cognac Special, etc., etc.
Cheers, Martin

Thanks Andi,
Our posts on this low traffic forum managed to cross. What's the chance of that, eh? I had to rely on Mel and Lloyd possibly making the heart attack known on SCB and SF if they could, but some people were bound to be missed. Anyway, I'm doing what the docs tell me and trying to keep mildly occupied, like labelling all my little plastic drawers today as it was a bit chilly in the workshop.
Cheers, Martin

Well Martin, if you're going to be making 19" Austin Seven wheels and tyres for Miss Bloody Mary, I guess I'm going to have to complete Mrs, JoJo.

Ah, goodo, Chris.
We'll tear you away from those cigar tubes you love so much.
I must say that, in order to fit as many cars as possible, the wheels err a little on the wide side, but with O rings as tyres or, I hope, a nice skinny one from Colin at RS and the 36 spoke look we won't be too far from scale, but those wheels and tyres on Mrs. JoJo AND Bloody Mary, etc. were the very thinnest of A7 wheels at around 3-25 x 19.
Later A7 wheels were as much as 4-75x16 and then there are all the naughty, non original 5-50x15s on the more modern racers, Specials, etc.
Of course, I don't HAVE to use the wheels complete. I might experiment with special turnings, air gaps and all that for my own models, haha!
What body are you using for Mrs. JoJo?
Cheers, Martin

This may help a little. John Bolsters original plans: Drawn up by Richard.

Ah, I've seen those plans, but they're for the single engined version, but the frame's the same, so I will be studying that tomorrow. Thanks mate.
As to those bodies, I think you have your work cut out for you trying to get anything remotely accurate out of them. I don't know Blau Maus in anything but name, but neither look like that photo of Mrs. Jojo!
Cheers, Martin

Chris, I hadn't found that site! You're a gentleman, sir. Many thanks.

Great job guys, very useful information. Those drawings and photos are fantastic.
I've always wanted to make some very small cars, such as these hill climbers or Formula 500's. The lack of suitable wheels is one factor that prevents me from starting one as a project. I'll be interested in seeing the wheels used on this car.
Drawings such as these are also so valuable. The lack of good reference photos and drawings is another impediment that prevents me from starting projects. A lousy excuse I know, but when I see such wonderful drawings as these, it makes me want to hold out until I find good documentation.
I'm tempted to make this hill climber myself, the drawings are so good...
Really looking forward to this.

Aurora,
don't let me stop you starting a model, please, but those drawings are of Bolster's single engined car, which didn't last long before the 4 engined one was built and finally the successful twin engined version, which I'm doing.
However, what about having a bash at Spider or Spider II, both GN framed, but parallel framed, unlike BM. There are loads of photos of Spider on the net.
As for wheels, RS Slot racing with me, are doing skinny 19" scale wheels with 36, 48 or 60 spoke photo etched spokes. Colin (Mr. RS) is planning a couple of skinny tyres to go with them. We have the wheels, we haven't got the p/e yet. But if you scale photos using the size of a wheel as a measure you won't go far wrong. From the BM drawing, I scaled the wheelbase as 6'-8".
Because reference is non existent as published drawings, you can make a model and nobody can gainsay you! Cheers,
Martin

Very similar to Spider, but with what I'm guessing is a whole Frazer-Nash front end, axle, hubs, brakes and wheels. Engine is an OHC type and those twin rear wheels seem to be a fixture. Number 3 on my list, unless something else nudges in to my interest.
Cheers, Martin

Now you guys have opened up a can of worms - I see several cars I'd like to make. The Spider is intriguing, and the GN JAP Grand Prix Special looks like a challenge too.
I've got some FF-030 motors that should be suitable. Looking forward to seeing these skinny RS wheels and tires, they could open up a whole new category of cars!
