The
Cadillac LY7 is a narrow angle 3.6L VVT V6. Unfortunately, the engine suffers
notoriously from early timing chain failures, especially in its first and
second generations from the early 2000s. To make matters worse, it’s generally
not possible to pull these engines in one piece without dropping the subframe and the front suspension and pulling the engine
out from underneath. Here’s the build-up of a new engine in place, leaving the
suspension, exhaust system, transmission, and subframe
in place.
It’s
difficult to up-tire dually pickups in the one ton class. If you slap wider
tires on the narrow wheels, the tires end up too close together – which can
capture rocks and destroy the tires -- and pinch down the beads far more than
design tolerances support, which accelerates wear, damages load carrying
capacity, and facilitates instabilities. If you go with custom 3-position dubs,
you lose off-road capability because the sidewalls are so low and the wheels,
aluminum. If you mount up 10-bolt hub adapters with MDT/HDT wheels and tires,
you have horrible ride quality. Here’s a way to run offroadable
17”x8-1/2” steels with good gaps and no loss of payload capacity.

When
I got tired of running custom billet 5-3/4” dually adapters in front to carry
my custom 17”x8-1/2” wheels – and my stock unit bearings started chirping -- I
reverted the front end to SRW Yukon Free Spins and aftermarket 17x9 wheels –
and lost 40 or 50 lbs per side while gaining an inch and a half of track still centered
on the new serviceable bearings.

how we brought back online a broken down German specialty production welder in
hours instead of weeks using a 3D printed cooling impeller.

I
started putting together an automotive model portfolio – my models of classics,
TV and movie cars, and some original designs. The virtual FTP folder contains a
pdf narrative and the automobiles discussed, in the order
described.

Early
Volvo 5-cylinder turbos used an Italian throttle body
with dual plastic wiper pots for TPS. There were dual pots because they failed
frequently and early, and having two meant you could go a little further once
one died. The throttle body controller was actually smart enough to detect
instabilities attributable to a worn potentiometer wiper and ignore it. This is
an illustrated guide to installing a popular contactless, wearless
Hall Effect refit and tuning it in.

I’ve always been fascinated by Caterpillar tread systems. I thought it might be a challenge to design a completely hardwareless system for hobby robots and complex toys 3D printed on a filament melt deposition 3D printer. It was. This details the design and the settings development, and provides links to downloads.

A
collection of my early artwork – a virtual ftp folder presenting images ranging
over years.
There are advertising images, personal projects, concept cars, and lots of
space stuff, most of which was developed as modeling tutorials in the old days
of the Compuserve 3D Forum. A couple novel covers are
thrown in.

Substantial
upgrades to our last San Antonio home’s utility room/kennel,
start to finish. I designed and custom ordered the cabinet modules, did tear
down and build-up myself, and then had the new countertops installed by pros.
