This is my Harrison M250 lathe. It's a 1984 model, but was installed in
a Government shop and was therefore little used. I had to change the motor
to a 220/1ph but otherwise it needed nothing but tooling. I just love this
machine! |

Here's a jig to hold clutch backing plates on the lathe while they're
pared down by 2 lb. The jig indexes the plate every 120 degrees to give it
that kinda triangular shape. The plate can also be centered for knocking
the back off or facing the friction surface. |
|
And here's what the plate looks like when it's done. At 4.4 lb it's
well within the 'safe' limit. |
|
Here's a solid centre flywheel which has had 4 lb taken off. At 13.8 lb
it's well within the 'safe' limit' |
|
Here's the latest mod for my distributors. I've installed needle roller
bearings (3/4" OD x 1/2" ID x 3/4" long) in the distributor body and made
a new shaft with an OD of 0.498". This solves a lot of the shaft movement
problems and with Luminition solid-state ignition, the spark is dead
accurate. |
|
Here's another jig used for lightening those grossly overweight 1300
rods.I use a 1/2" ball end mill cutter to put a slot across the balancing
pad, then round the thing over and shape it nicely. This doesn't reduce
the weight much, but every little bit counts. |
|
Here's a crank being tapered on the lathe. It's already been wedged on
the mill. This process only takes about 2 lb off the piece, but the
polishing process eliminates stress concentration sites. After the
polishing is done, it gets nitrided, leaving a nice satin black finish. |

My 500lb workbench made from 4x4x0.25" angle iron with a steel top, a
bay for the air compressor (left) and 2 huge drawers for rags. Scrap
stainless sheet was liberally utilized. Free is good!! The A-frame engine
hoist is designed to straddle the bench so engines can be picked up and
dropped effortlessly. NOTE! The bench is unusually TIDY!! |
|
The bench has 2 roll out carts designed to support engines during iccy
tear downs. The shelves underneath are for the casings and other bits, but
while the Cooper S is all torn apart, this area is for storage of
goodies. |
|
In the corner of the bench is this custom A series engine stand. It's
made from 4" diameter, 1/4" wall, steel tube. There's an axle in the head
which makes rolling the engine upside-down a snap. The base sucks. I made
it from a rotating base for a vice, but it is too light for the torque
being applied, so I'll be making a new one from 1/2" steel plate and
bearings. |

A deadwheel drive for the Halda odometer. I managed
to find several 8:1 worm gear sets, but the pitch centre is larger than
the Halda stuff, so I had to make my own housing. Works like a damn and
because the gears are hardened steel they should last
forever. |
|
Here’s a look at the corner of my shop in May 2002 with my new milling
machine in place. It’s a Bridgeport clone with power quill feed, power
traverse and DRO. It sits right beside my Harrison M250 and I don’t know
how I ever worked without either of these! On the right is the engine test
stand, details for which you will find on my EFI project
page. |
