Double Pulley

A few weeks ago I asked my brother to cut a short H20 pump double pulley for me out of some billet aluminum stock. He dropped it off last night, I want to hang it up in the living room, but it's going on the car tomorrow. I should have the A/C in the Squire up and running just in time for Christmas.

Or a log manifold made of oregin or pinus radiata...woodern spoon for you addo, that's wickedly funny.
 
No, I was serious. During WWII, a few hard-up Brits discovered that old, seasoned oak made half-decent pistons. It "glazed" as the resins burned to form a gas-tight coating, and the charred top didn't hurt a low-compression undersquare motor. I have heard of these still turning up (no pun intended) during overhauls in the '80s.

Compared to that duty, a tough, long-grained timber would do well as a pulley.

I have seen a four-cylinder car engine with a wooden piston (and three
alloy ones), turned up from lignum vitae from a bowling ball... It was
even running fairly well, we stripped the head because it was burning a
lot of oil :-)

but i wanna know more!!!!!!!
this sounds very cool...
 
People think ebony is hard and dense. Well, lignum vitae creams it for toughness. This stuff is a greenish dark brown and as the guy says, was once used for bowling balls. Bakelite took over that duty, but LV is a precious and valued timber; even a decent piece 2×3×4" will be worth money, so bowling balls become mallet heads, chisel butts, file and gouge handles. It is really, really heavy.

People were more resourceful "back then". One set of brake shoes off the Singer have been hand made by a blacksmith - it took careful inspection to reveal this. Austerity in wartime UK was no joke either, so improvisation was the way to get ahead.

Wow, man. And I thought I was just takin the pi$$ out of you. Thanks for that.

I guess you'd use woodern pistons of the same age for a six, or it may need re-ringing..

May be cheeper than forged pistons :hmmm: :smash:
 
:lol: I got it! But imagine the 'phone call from the mechanic: "You know that knock? Number four had borers in it."
 
Or "we split the piston but the bore is fine".

I like wood, it is never truly dead, and that stuff can cop a hamering
 
Wood? From an old bowling ball?
Personally, I think I'll stick with aluminum (from beer cans!), although there is some harmony here, as beer and bowling go nice together...
If somebody really wants to turn one out of wood (or aluminum), here's a scan of the plans I drew up for mine:
