The Restoration: Lotus 51a chassis # 51A/FF/119
Paint Scheme ideas
Party- Invited my
local car club, the Brazos
Brits, over for a party where the theme was
strip the chassis
to ready it for blasting.

after only ~3 hours of Brits work !!

and ready for "chroming". Actually a
lot of the bits like the driveshafts, front uprights and many
smaller pieces were nickel plated so they polish up real nice.
This may not be the fastest car on the track, but it's going to start
out as the cleanest!
on the car! Look at it shine!
the engine and gearbox apart.
Engine looked good except for scores on the crank bearings so it is now 30/30 under. Inside of block was deburred and painted by previous builder - looked nice! Gearbox was leaking from the front and rear covers as well as one output shaft seal, so it is getting new gaskets and rubber (oh, to replace the shaft seal get the big c-clip out and the shaft and all will come out with it - shaft has a big nut on the inside end that is then removed once out of the car). Apparently the gaskets are no longer made (it's the renault R8 / type 330 box) so I'll make up a set. Front seal seemed to be something lotus had laying around (see tech for part number) as it wasnt standard lotus elan/cortina/7 stuff nor renault, but the local bearing place had it on the shelf.
||Throw out bearing has proven
hard to find but only because it was masked with a bearing carrier from
a 60ish era ford anglia, and a fabricated bobbin lotus made up to get
the spacine right. The bearing itself turned out to be the plain
old round nose ford unit used in many lotus with ford blocks.
From the part numbers my local bearing place had no problems crossing
it, but it kept coming up obsolete regardless of manufacturor.
The carrier is no longer made. smallfordspares.co.uk have the
carrier in a diagram for 105 gearboxes, but it was 105speed.com that
had some used ones and sent me one for $30. Photo of unit dissasemled.

is rebuilt! Ready to be mated to the gearbox and put in the car
soon to be connected up to its 6000rpm max heathkit homemade tach that
came with the car.
(and yesterday, and last week, and last month, and tomorrow....)
|Cleaning and polishing hardware
- it never ends! And yes, the "dust proof" laptop is up to look
at photos to see where in the heck the bolts go!
Brakes! note to self-
put aluminum side panels on before suspension!
(3 masters, 1 slave, and 4 calipers is way to much to rebuild in a row - need a break!)
|| Update: after some long
engine trials, and a new crank after finding a crack, i've had it out
for a couple practices and one race weekend. The car ran
competitivly, at the front of mid pack. That will improve as i
get used to driving a formula car. Ran 1:56 as best time on a hot
weekend at TWS, long course. Not bad for first full race
weekend. This will probably be the last update, with future news
on the main 51 page.
