Firsky's in the early days, a reminice from Alan Hitchcock

[Bob Purton]

Whilst we are on Friskies, can John tell me if the chassis are brazed together or welded? I believe that Zeta's are brazed.

[marcus]

Pardon my ignorance, but were Frisky brakes unique or adapted from something like an Austin A 30? Just curiosity!

[john Meadows]

All the prototypes including the Sprint, were brazed and also some of the earlier cars.  The later ones were welded

I don,t know on the Zeta but I bet Fred Diwell does.

Ref the brakes, most bits on a Frisky were either off, or adapted from another car.


General comment - The Sport rear hubs were a mass produced item off the shelf in 1958. but the brake linings were an odd size because the MIRA upon testing the brakes said they were excessive so they cut down the lining area to reduce the friction

Wheels       10inch as Bond Mk G, Lightburn Zeta

Rear Brakes       Mini brake shoes drums cylinders, back plate will fit most F3's

Front Brakes      Front Brake cylinders as pre 1962 Morris Minor
(F3 had hydraulic brakes only on the front wheels, with only a handbrake on the rear)

Shoes         Front   LB 3067 DC 202,  Rear 3068 DC 202
         Also Mintex MRL2  compares with LB68 (info of an empty             Mintex brake pads box)

Hyd Brake cylinder   Replacement parts Mini Mk1  KL71535

Bleed screws      BMC part 3H 2428  


Master Cylinder   Lockheed 95292 (kitKL71571)also 91622 (3872) 3/4" fits with brakehose BH120 Same parts as Standard 8 car & Triumph Herald?   Also try Lockheed VauxhallVictor

Well you did ask!

Cheers John, I had a feeling they might have BMC ancestry.

[Bob Purton]

I know Zeta's are brazed because I examined Nick Polls car. It had something to do with reducing the risk of stress cracking on competition chassis joints.

[marcus]

Makes sense... my understanding is that brazing is slightly less strong than weld, but more flexible, so it is less inclined to fracture for a given mass/material/joint type.

[john Meadows]

I'm sure I'm teaching my granny  to suck eggs here but when welding the two metals melt run into each other and become one upon cooling. Brazing on the otherhand is more akin to a strong glue. I spent my formative years working for BOC and belived that brazing was not alowed on structural members on production cars despite the fact it was virtualy as strong, but I could be wrong!

I have an apology to all you Frisky fans as I fed you bit of bum information about the Sprint.

The Sprint was not to be built at Vickers-Armstrong (Aircraft ) Ltd, an agreement had been reached by October 1958  that they would make the front Suspension, and negotiations were taking place for them also to make the chassis and running gear.

The Sprint was to be built by Frisky Cars Ltd at Meadows.

Vickers did offer full use of their wind tunnel facilities for testing

But as I said it never went ahead, but I hang my head in shame for misleading you all
