I was struggling to think why you'd want to clean up an acorn shell...

Well the cooling fan passes air through it on this one so it needs a good
clean every now and again...

That UJ is in excellent shape compared to one I once replaced in the
propshaft of a Mk 1 Triumph 2000. The bearing journals on *that* UJ
had not only long since ground the needles to powder, they had also
ground themselves into a conical shape. There *was* a bit of a clunk
in the drivetrain, as I recall. It's truly amazing how bad those
joints can get, yet still perform their basic function.

Loved the final frame "Now how am I going to do the chassis".

If only...

I've got some ali castings which are an absolute bugger to clean - all nooks
and crannies, even a toothbrush won't do the job. Have heard rumours of an
electrolytic process which sounds ideal, but can't find out anything
further.

Anything known? Does it work? Where can I get it done?

TIA,

My understanding is that (salt or other) corroded aluminium casings can
be cleaned by rubbing with a warm/hot mixture of 50/50 (old pickling)
vinegar and water. The addition of a drop or two of washing up liquid
in the mix might improve wetting and cleaning effectiveness.

I can't answer your question, but I suggest you look in Yellow
Pages for an engine reconditioner, and give them a ring. One
local to me had an chemical tank for cleaning old engine parts.
Immersed in the tank for a few hours, then hosed with a steam
cleaner, resulted in parts that were spotless.
Dunno what the chemical was, but it was one made specifically for
the job.

Strong alkaline chemical.

One item that has come into play recently is glass bead blasting of
parts like aluminum heads etc. we have found that the beads get forced
into porosity and cleaning sometimes does not remove all the beads, some
have taken up to three years to work themselves out into the engine -
with bad results.

Far better to use an acid cleaner on aluminum. Alkali eats alloy and
gasket faces will be etched.
