Dec 2021 pics of Sprite

Still much work to do on what is quite a rough car; at the moment just about back on the road for some test runs, carb and brake adjustment, install and wire up AH horn push and column cone  (to complete the installation of a recently acquired Lempert replica Falcon Le Mans steering wheel); some welding for seat belt mounts in the inner sills, sort some of the paint issues, repair off-side wing, lower portion (or replace with a good secondhand heritage wing have in stock), maybe install the GRP bonnet and rear boot lid I have, weld in mounts for rear roll cage and install rear cage (Aleybars with removable diagonal) perhaps do a few hillclimbs later in 2022. 

Longer term plans will be bodywork including return to its original Speedwell Blue, put in proper floor panels (to replace previous owner’s homemade panels), plus build and install an overbored 9CG engine using NoS oversized (plus 20 thou) flat top high compression Sprite pistons for the 948 engine (capacity to be 960cc). And put on a Warwick MkII hardtop (if I can find one to go with the glass rear side windows for this hardtop that I already have).

Locost - new project

Aug 2019

I collected a new project - a Locost 7. Plan to build up into a road-legal hillclimb car. Get the Sprite back on the road first.

Jan 2022 pics to ID chassis on Locostbuilders forum (is it a Stuart Taylor Motorsport [STM] chassis?), No work carried out since purchase. Note front towing eye, steering rack mounts and upper and lower suspension wishbones, hooped steering column mount, rear towing eye. Also additional round tube in tunnel (as per 750 MC Locost Championship regs?). Chassis thought to be a former 750 MC Locost racer. May be repairs to front chassis?

Rear brake cylinder sizes

Comparison of wheel cylinder sizes.

Lockheed rear wheel brake cylinder, twin piston comparison as found on BMC rear axles [Midget, Sprite, Austin A40] and Mini rear. Fixed cylinder, one per side.

Cylinder bore
part number
AP Caparo
part number
Old Lockheed
part number
Notes on original applications (not an exhaustive list; approx years)
1/2" (0.5)

Mini 1275GT rear - 1975 to 1976.
5/8 (0.625)
Mini Mk1 Cooper S with servo; rear.
Mini MkI (not Cooper or Cooper S) rear - 1962 to 1967
9/16" (0.563)

Mini MkI rear - 1959 to 1967
9/16" (0.563)

Mini MkIII rear - 1974 to 1978
11/16" (0.689)
MG Midget [1500] rear - 1975 to 1979.
Mini 1275GT rear - 1964 to 1975.
3/4" (0.75)
Austin Healey Sprite & MG Midget (1098 & 1275 engines) rear, 1964 to 1975.
Austin A40 Mk2, rear - 1962 to 1968.
Mini MkI (not Cooper or Cooper S) rear - 1959 to 1962.
Mini MkII (not Cooper or Cooper S) rear - 1967 to 1975
plus other Minis
7/8" (0.875)
1962 MG Midget Mk1 & Austin Healey Sprite MkII rear (with front drum brakes and twin piston fixed single rear wheel brake cylinders). NB earlier cars have sliding single piston wheel cylinder of 7/8" bore in a different back-plate.

NB position of locating pin and matching hole in original rear brake back-plate may vary, so might need to drill different locating pin hole in rear brake back-plate if considering changing sizes of wheel cylinder outside original application.

Note early Austin Healey Sprite and MG Midgets (until approx late 1962) as well as Morris Minors had a different style wheel cylinder (single piston, sliding), rather than the above fixed cylinders with dual pistons..

Would MGB wheel cylinders GWC1103 (7/8" [0.875]) - MGB GT and MGB Roadster GWC1122 (13/16"? 31/64? [0.8?]) fit any of the above rear back-plates?

Rear brake backplate comparison

On the left In pictures 1 and 2 below - early Sprite and Midget (948 engine and front drum brakes) with sliding single piston single wheel cylinder (7/8 inch diameter piston bore); middle is the later 1098cc and 1275cc engined Sprite and Midget (had front disc brakes) with a single wheel cylinder with twin pistons (3/4 inch diameter) which is fixed, not sliding, and on the right is the Wolseley 8 inch.

Note do not have a picture of the 1500 engined MG Midget rear brake backplates for comparison and whether these differ from 1098/1275 backplates (may be difference on location of wheel cylinder mounting pin hole?).

First picture below shows the rear of the rear backplates and the second picture below shows the front of the rear backplates.

                                                                       Picture 1

Picture 2

Picture 3

Picture 3 above - comparison between early and later backplates and wheel cylinders - upper pair of backplates are early Sprite/Midget: note the sliding wheel cylinder is a Morris 1000 of 3/4 inch bore, rather than the 7/8 inch bore rear wheel cylinders for MkI & II Sprites that have front drum brakes (my 1961 AH Sprite MkII has front disc brake conversion). Lower pair of backplates are later Midget and Sprite with single twin piston wheel cylinder.

Historic Monte Carlo Rally start in Paisley, Scotland

I went to one of the start points for the 2018 Historic Monte Carlo Rally in Paisley, Scotland last night (31 Jan) 

Great fun - the attached picture sums it up 

Picture is of a 1934 Lagonda M45 Tourer crewed by James Mann and Tracey Miklaucich, car in same family since new and first rallied on the RAC in 1934 and first Monte Carlo rally in 1936 and rallied off and on ever since!. 

There were also other cars from the 1930s to 1970s, such as Triumph Herald, Ford Popular, Mini Cooper, MGB, SAAB V4, MG TC. No Midgets or Sprites this year from this start point.
