Aluminium Grades

Diesel injection pump isn't really suitable, the clearances inside required to get up to 115 bar to 280 bar - 1700 psi to 4,000 psi means the slightest lack of lubrication or grit and it's toast.

Going slightly off topic but whilst looking up these pressures which I had forgotten [ past life ] I found out that the latest diesel with high pressure common rail systems use pressures up to 2,000 Bar or 29,400 psi.

Home made water jet anyone ?

They are even more fragile....Some reduce engine power and even cut the engine to "not" run out of fuel....kills the pumps.

Right, Didn't know that not had the pleasure of owning / running one of these our two vehicles are on the last of the mechanically injected engines with no brain etc.

Hate to loose this independence.

On topic I did tell Michael T6 machined OK

Im told that the Al from pistons is nice to work, melts nicely for casting into ingots and machines cleanly. Another reason to visit Looms?
Havent used pistons myself but I have used hard disc chassis; nice light alloy that melts easily (dont know temps - got no thermocouple).
Used the melt to cast a replacement key cos the buggers* wanted £8.50 for what seems to be a bog-standard mortice key.
Theres someone with a website about casting etc who uses HDD Al regularly with good results, I'll try and dig out his URL.

Does anyone in the Derby/Notts area know a good source of fire bricks?
I only need a dozen or less for a small electric Al melting project, I dont need a pallet full! Preferably the ones you can cut with a wood saw.

*I tried 3 different keycutters, one had a nice engraver that looked PC driven. He wouldnt let me play after Id sniffed at his prices.:heehee:
